Hello!

Thank you for the quick hint!

I have downloaded and compiled the v4l drivers rom the mercruial-repo.

If i set the USB_PID_MSI_DIGI_VOX_MINI_II to 0x0506 i get following dmesg:

this continues... to reset and restart

the folder /dev/dvb/adapter0/ is created anyway.
#dvbscan --> Failed to open frontend

In case of "define USB_PID_LIFEVIEW_TV_WALKER_TWIN_COLD 0x0506" the  
cpu-load goes up for about 30 seconds, but i was unable to get the dmesg,  
bec. my keyboard somehow get locked (no response on any keypress, even  
numlock was disfunct).

With USB_PID_DPOSH_M9206_COLD set to 0x0506 it seems not to work at all...
dmesg after plugging in:
[  283.191498] usb 6-3: new high speed USB device using ehci_hcd and  
address 9
[  283.306767] PM: Adding info for usb:6-3
[  283.306878] PM: Adding info for No Bus:usbdev6.9_ep00
[  283.306909] usb 6-3: configuration #1 chosen from 1 choice
[  283.307003] PM: Adding info for usb:6-3:1.0
[  283.307095] PM: Adding info for No Bus:usbdev6.9

I have done a first quick dvb-snoop on Windows XP (running in a VMWare).  
The log contains the plugin of the COLD device, it seems to get some  
commands, then replugs as the hot (0x0500 as far as i can see).
   The logfile: http://nopaste.info/eead046817.html

Firmware:
I did not get any hint (by dmesg), which (or if at all) firmware is sent  
to the stick... how can i debug this? Or where is it defined, which FW is  
send to whom?

TIA
Daniel Weigl
