I've recently bought a Freecom DVB-T USB Stick. It works fine in
Windows, but on the same PC (Samsung V25 portable, 2.4 P4, 512Mb ram)
with Suse 10.0 OSS it does not seem to be recognised...

lsmod | grep dvb

dvb_usb_dtt200u         8580  0
dvb_usb                17928  1 dvb_usb_dtt200u
dvb_core               77480  1 dvb_usb
firmware_class          9856  2 pcmcia,dvb_usb
i2c_core               20368  3 i2c_algo_bit,i2c_i801,dvb_usb
dvb_pll                 9348  1 dvb_usb
usbcore               112512  7

dmesg | grep dvb

dvb_usb: module not supported by Novell, setting U taint flag.
dvb_usb_dtt200u: module not supported by Novell, setting U taint flag.
usbcore: registered new driver dvb_usb_dtt200u

So, I think the correct modules are loaded?

lsusb -v

Bus 004 Device 003: ID 14aa:022a AVerMedia (again) or C&E

  bLength                18

  iProduct                0

  Configuration Descriptor:
    bLength                 9
    bDescriptorType         2
    wTotalLength          171
    bNumInterfaces          1
    bConfigurationValue     1
    iConfiguration          0
    bmAttributes         0x80
    MaxPower              100mA

Again, this looks OK.

However, when I unplug/plug in the stick dmesg gives:

usb 4-3: USB disconnect, address 3
usb 4-3: new high speed USB device using ehci_hcd and address 4

Ie. It doesn't seem to recognise the device as dvb-usb. The LED on the
USB stick remains off.

My /lib/firmware has dvb-usb-wt220u-01.fw (I've also tried

The device does not appear if I do a "cat /proc/bus/usb/devices"

Any ideas? From what I can make out from hours of googling these devices
should work OK.
