== Introduction ==
* [[ATSC USB Devices]]
Here is a market overview of available DVB/ATSC USB devices sorted by its required LinuxTV driver (if supported - and yes - most of them are). Generally it is a good idea to use dvb-kernel from CVS, because some drivers can be very new and thus have not made their way into the mainstream kernel.
* [[DVB-C USB Devices]]
* [[DVB-S USB Devices]]
* [[DVB-S2 USB Devices]]
* [[DVB-T USB Devices]]
* [[DVB-T2 USB Devices]]

__TOC__
Please help to keep this list up-to-date so that it is useful for everyone!
==Introduction==
'''For all DVB USB devices you will need to load (if not compiled into the kernel):'''
* i2c-core
* crc32
* firmware_class
* dvb-core.ko
* dvb-pll.ko
and maybe others too. If the loading fails for any particular module you'll get a "unknown symbol" message. Then have a look at dmesg to find out, which symbols (functions) are missing. After you've found out which module was absent, please come back here and add it to the list/device-entry.


The ''Type'' field specifies the USB standard(s) supported by the device.

; USB1.1
'''Legend:''' the field type specifies the real USB-standard of the device
: The device supports USB 1.1 only, and will work at 1.1 speeds when attached to a USB 2.0 port.
- '''USB1.1''': the device can be run on the USB1.1 and on the USB2.0 bus but only with USB1.1-speed.
; USB2.0
- '''USB2.0''': the device can only be connected to a real USB2.0 port and runs with USB2.0-speed.
(delivering the complete [[TS|Transport Stream]] to the software demuxer.)
: The device supports USB 2.0 only, and will not work when attached to a USB 1.1-only port. Such devices are normally capable of delivering the complete [[TS|Transport Stream]] to the software demuxer.
; USB2.0, USB1.1
- '''USB2.0/USB1.1''': the device is actually USB2.0, but can also be driven on a USB1.1 port. (if not
mentioned elsewhere, these boxes can deliver the complete [[TS|Transport Stream]] when running in USB2.0 mode)
: The device supports USB 1.1 and USB 2.0, and will work at any speed supported by 1.1 or 2.0. When running in USB 2.0 mode, such devices can deliver the complete [[TS|Transport Stream]] (unless specified otherwise).


== Firmware ==
== Firmware ==


Most of the USB devices need a firmware to run. Some of the firmware files can be downloaded here: [http://www.linuxtv.org/downloads/firmware/] or here: [http://www.thadathil.net/dvb/fw/] .
Most of the USB devices need firmware to run. Some of the firmware files can be downloaded from [http://www.linuxtv.org/downloads/firmware/ here].


You need to copy the firmware to the correct place on your system. This will normally be /lib/firmware or a folder below it. Here is an example:
== Additional technical information ==


- $ cd /lib/firmware
This section starts describing devices which hit the market beginning of spring 2004. It does not cover TTUSB-based devices.
- $ ls
- 2.6.15-23-amd64-xeon
- $ cd 2.6.15-23-amd64-xeon
- $ sudo cp ~/dvb-usb-umt-010-02.fw .


Now, you need to unplug your USB device. Plug it in again, and then take a look at dmesg.
=== DVB-USB devices host-controlled ===
- $ dmesg
- < ...... lines cut for clarity ..... >
- usb 5-2: USB disconnect, address 3
- usb 5-2: new high speed USB device using ehci_hcd and address 8
- dvb-usb: found a 'Hanftek UMT-010 DVB-T USB2.0' in cold state, will try to load a firmware
- dvb-usb: downloading firmware from file 'dvb-usb-umt-010-02.fw' to the 'Cypress FX2'
- dvb-usb: Hanftek UMT-010 DVB-T USB2.0 successfully initialized and connected.
- usb 5-2: USB disconnect, address 8
- dvb-usb: generic DVB-USB module successfully deinitialized and disconnected.


In this case, I have success, because the firmware was loaded.
When first AC-Adapter-free USB devices (with the capability of receiving DVB Signals) hit the market, every vendor was using the generic USB-device-controller from Cypress (FX1 (AN2135/AN2235), FX2) as an interface between the DVB-hardware and the host.


Remember that on some system the firmware is loaded by udev, so if for some reason the firmware is not loaded you may check that
As those controllers are very generic, one has to create (and download) an (small or not so small) embedded software to those controller to give vendor-specific and the wanted functionality. After downloading the so-called firmware vendors used the reboot-feature of the controller to re-enumerate with new USB Vendor/Product-IDs and a new USB-layout. On the host this looks like a normal disconnect and connect of an USB device.
udev is acutally running.
To check you could for example issue the command:
- $ ps -e | grep udev


If the output is empty, then you have to restart the udev daemon. For example in a Debian based system you may try with:
Because the memory for storing the firmware was limited, vendors decided not to put any DVB-demodulator and RF-tuner specific code into the firmware, but only to implement interface functionality. At that time, the common way to control other components was [[I2C]]. The other necessary feature was data-streaming. With such a firmware, every functionality is done from the host - mainly the driving of the demodulator and the tuner.
- $ sudo /etc/init.d/udev restart


then try again, removing and inserting the module again with modprobe.
Host-controlled devices are the ones based on DiBcom (dibusb, dib0700), Nebula (DigiTV), Hanftek and others. (see below)


== Additional Technical Information ==
=== DVB-USB device firmware-controlled ===


This section starts describing devices which hit the market beginning of spring 2004. It does not cover TTUSB-based devices.
Another approach was coming later: When it started, that putting more memory on a board/into an IC with almost no increase of the [[BOM]]. Vendors started to put the demodulator and tuner-driver into the firmware. This was simplifying the host-part dramatically, because if you have a new hardware, you just need to modify the (platform-independent) firmware part and, as long as the firmware-interface is not changing, the host-driver stays the same.


=== Host Controlled DVB USB Devices ===
Firmware-controlled devices: Twinhan VP7045/VP7021, Terratec Cinergy T2, Wideview and others.

== DVB-T ==


Because the memory for storing the firmware was limited, vendors decided not to put any DVB-demodulator and RF-tuner specific code into the firmware, but only to implement interface functionality. At that time, the common way to control other components was [[I²C Protocol|I²C]]. The other necessary feature was data-streaming. With such a firmware, every functionality is done from the host - mainly the driving of the demodulator and the tuner.
=== AVerMedia AverTV A800 ===


Host-controlled devices are the ones based on DiBcom (dibusb, dib0700), Nebula (DigiTV), Hanftek and others. (see below)
All devices below are fully supported by the LinuxTV driver. The following drivers are needed for these devices:
- dib3000-common.ko
- dib3000mc.ko
- dvb-usb.ko
- dvb-usb-dibusb-common.ko
- dvb-usb-a800.ko


=== Firmware Controlled DVB USB Devices===
These [[frontend|frontend(s)]]/[[demodulator|demodulator(s)]] can be found in various revisions of this device:
- [[DiB3000P|DiBcom 3000P]]

(The driver was completely [[reverse-engineering|reverse-engineered]] without the help of its real vendor (assuming WideView is the manufacturer - UPDATE: the vendor was so kind to provide information about unknown commands, hence the driver is complete))

'''Attention:'''

There is a new Firmware 1.0.2.14 for the MD 95700 from Medion available.
You can download it directly from the Medion Webserver. [http://www1.medion.de/downloads/index.pl?op=detail&id=2804&type=treiber&lang=de]

'''Please read the Readme''' befor you flash the Box.

This update fix some Videoproblems.
But the new Firmware is incompatible with the old dvb-usb Driver's.
You need the new dvd-usb drivers (cxusb.c >= V1.5 and cxusb.h >= 1.2)
Have a look to the cvs-tree dvb-kernel/linux/drivers/media/dvb/dvb-usb [http://www.linuxtv.org/cgi-bin/viewcvs.cgi/dvb-kernel/linux/drivers/media/dvb/dvb-usb/]

== Unspecified/Unknown devices ==

If you own one or more devices from the following list and you want to help the development, please contact the [[linux-dvb-ml|linux-dvb Mailing list].

=== Anysee Edition 30 DVB-T USB2 ===

The design seems to be similar with the Twinhan Alpha Stick (same Tuner and Demod), but it doesn't work with the alpha-driver (vp7045) and firmware.

Anysee doesn't want to help OpenSource-developers to write a linux-driver by handing out specs. Reverse-engineering would be possible anyway, but why, there are plenty of other USB devices working in Linux.

[http://anysee.com/]

=== DVBWorld (?) DVB-S USB2 Box ===

[http://www.dmsiusa.com/usb_box.htm]

=== SIEMSSEN & CO. - Opera S1 ===

A similar deviece to the DVBWorld seems to be sold in Germany by one of the well known discounters and its german distributor is Siemssen [http://www.siemssen.de/] under the name Opera DVB-S1.
The card contains a Cypress CY7C87013A-56PCX to manage the USB-Part that seems to control a Xilinx Spartan(R) XC3850 FPGA. The tuner box reads Sharp, but I cannot find out more about it.

I'm able to upload the firmware to turn the device from cold mode to warm USB ID but programming the FPGA still fails.
For my card/driver:
The cold USB ID is: VID 0x04b4 (CYPRESS) PID: 0x2830
The warm USB ID is: VID 0x695C (???????) PID: 0x3829


DVB-S cards in similar cases can be found on different asian sites
[http://www.dvb-device.com/ace42sc.htm]
[http://www.szforwardvideo.com/en/manager/product_read.asp?ID=96]

Despite of the fact, that all those devices look quite similar and have similar hardware, siemssen still claims that they are build completely different and their drivers can not be exchanged in any way.

With this setup you will have bandwidth problems with no appropriate warning whatsoever on any log file. Except that video will look horrible.

For information about supported USB devices, see the appropriate device category:


Introduction

For all DVB USB devices you will need to load (if not compiled into the kernel):

  • i2c-core
  • crc32
  • firmware_class
  • dvb-core.ko
  • dvb-pll.ko

and maybe others too. If the loading fails for any particular module you'll get a "unknown symbol" message. Then have a look at dmesg to find out, which symbols (functions) are missing. After you've found out which module was absent, please come back here and add it to the list/device-entry.

The Type field specifies the USB standard(s) supported by the device.

USB1.1
The device supports USB 1.1 only, and will work at 1.1 speeds when attached to a USB 2.0 port.
USB2.0
The device supports USB 2.0 only, and will not work when attached to a USB 1.1-only port. Such devices are normally capable of delivering the complete Transport Stream to the software demuxer.
USB2.0, USB1.1
The device supports USB 1.1 and USB 2.0, and will work at any speed supported by 1.1 or 2.0. When running in USB 2.0 mode, such devices can deliver the complete Transport Stream (unless specified otherwise).

Firmware

Most of the USB devices need firmware to run. Some of the firmware files can be downloaded from here.

You need to copy the firmware to the correct place on your system. This will normally be /lib/firmware or a folder below it. Here is an example: 

- $ cd /lib/firmware
- $ ls
- 2.6.15-23-amd64-xeon
- $ cd 2.6.15-23-amd64-xeon
- $ sudo cp ~/dvb-usb-umt-010-02.fw .

Now, you need to unplug your USB device. Plug it in again, and then take a look at dmesg. 

- $ dmesg
- < ...... lines cut for clarity ..... >
- usb 5-2: USB disconnect, address 3
- usb 5-2: new high speed USB device using ehci_hcd and address 8
- dvb-usb: found a 'Hanftek UMT-010 DVB-T USB2.0' in cold state, will try to load a firmware
- dvb-usb: downloading firmware from file 'dvb-usb-umt-010-02.fw' to the 'Cypress FX2'
- dvb-usb: Hanftek UMT-010 DVB-T USB2.0 successfully initialized and connected.
- usb 5-2: USB disconnect, address 8
- dvb-usb: generic DVB-USB module successfully deinitialized and disconnected.

In this case, I have success, because the firmware was loaded.

Remember that on some system the firmware is loaded by udev, so if for some reason the firmware is not loaded you may check that udev is acutally running. To check you could for example issue the command: 

- $ ps -e | grep udev

If the output is empty, then you have to restart the udev daemon. For example in a Debian based system you may try with: 

- $ sudo /etc/init.d/udev restart

then try again, removing and inserting the module again with modprobe.

Additional Technical Information

This section starts describing devices which hit the market beginning of spring 2004. It does not cover TTUSB-based devices.

Host Controlled DVB USB Devices

When first AC-Adapter-free USB devices (with the capability of receiving DVB Signals) hit the market, every vendor was using the generic USB-device-controller from Cypress (FX1 (AN2135/AN2235), FX2) as an interface between the DVB-hardware and the host.

As those controllers are very generic, one has to create (and download) an (small or not so small) embedded software to those controller to give vendor-specific and the wanted functionality. After downloading the so-called firmware vendors used the reboot-feature of the controller to re-enumerate with new USB Vendor/Product-IDs and a new USB-layout. On the host this looks like a normal disconnect and connect of an USB device.

Because the memory for storing the firmware was limited, vendors decided not to put any DVB-demodulator and RF-tuner specific code into the firmware, but only to implement interface functionality. At that time, the common way to control other components was I²C. The other necessary feature was data-streaming. With such a firmware, every functionality is done from the host - mainly the driving of the demodulator and the tuner.

Host-controlled devices are the ones based on DiBcom (dibusb, dib0700), Nebula (DigiTV), Hanftek and others. (see below)

Firmware Controlled DVB USB Devices

Another approach was coming later: When it started, that putting more memory on a board/into an IC with almost no increase of the BOM. Vendors started to put the demodulator and tuner-driver into the firmware. This was simplifying the host-part dramatically, because if you have a new hardware, you just need to modify the (platform-independent) firmware part and, as long as the firmware-interface is not changing, the host-driver stays the same.

Firmware-controlled devices: Twinhan VP7045/VP7021, Terratec Cinergy T2, Wideview and others.
