Here are some suggestions on how to go about it: 1. get vmware player and recompile kernel with usbmon 2. install windows and drivers 3. rmmod ehci_hcd (vmware might freak out your computer otherwise) You will probably need these and probably some more to get usbmon working: (look up with google) mount -t debugfs none_debugs /sys/kernel/debug modprobe usbmon mount -t usbfs none /proc/bus/usb chmod -R a+rw /proc/bus/usb (security!!) To fetch the firmware: 1. Unplug aerial cable so that no other data comes out of the device. 2. Kill/remove program called uremote.exe (if you have it) as it will cause i2c traffic that's not very interesting. 3. Plug you device and look for something interesting data being sent to the device. These should be control messages - look up usb spec for more details. It should get sent immediately after device is connected so you don't have to start any dvb software. You will probably need to write another script to turn that firmware into binary from. Attached perl script should put some sense to usbmon logs and m9206 i2c messages. Be aware though that it might break easily. AFAIK, vmware does not seem to support isoch/bulk transfers so you probably wont see any picture. -- Aapo Tahkola
