Hello!

I try to use a Hauppauge DEC3000-s USB box with my Linux machine. I am using a 
self-compiled kernel 2.6.18 from kernel.org.
The firmware seems to be loaded:
dmesg output:
ohci_hcd 0000:00:02.0: wakeup
usb 2-3: new full speed USB device using ohci_hcd and address 6
usb 2-3: device descriptor read/64, error -110
usb 2-3: configuration #1 chosen from 1 choice
ttusb_dec: Firmware 2.28<6>ttusb_dec: found DSP code "DEC2540-t".
usb 2-3: USB disconnect, address 6
ohci_hcd 0000:00:02.0: wakeup
usb 2-3: new full speed USB device using ohci_hcd and address 7
usb 2-3: configuration #1 chosen from 1 choice
DVB: registering new adapter (DEC3000-s).
DVB: registering frontend 0 (TechnoTrend/Hauppauge DEC3000-s Frontend)...

The devices under /dev/dvb/adapter0/ are created. But I get an error when I 
try to scan:
scan /usr/share/doc/dvb-utils/examples/scan/dvb-s/Astra-19.2E | tee 
channels.conf

Done.

dmesg gives:
ttusbdecfe_read_status: returned unknown value: 0
ttusbdecfe_read_status: returned unknown value: 0
ttusbdecfe_read_status: returned unknown value: 0
...

I do not know if this is okay, but the box seems to hang after the firmware 
has been loaded. I cannot turn it off with the remote control anymore.

I have tried to find some information about these error messages but had no 
luck. I hope that you can tell me what I am doing wrong.

Benjamin Eikel
