Re: [linux-dvb] AVerMedia AverTV Hybrid Volar HX (A827) support?

[Ivan Kuten <ivan.kuten@promwad.com>]

Hello Zdenek, Antti

I have some spare time to do some work.
First step I need to make USBsnoop working to see where firmware upload goes.
Those logs I posted seem a little bit broken, right, because XP crashes and system reboots
when usbsnoop enabled. But anyway usbsnoop capture some data.

Antti, can you post a part of usbsnoop log where firmware is loaded?

Regards,
Ivan
