Hi, i have the same problem in Raspbmc with Avermedia A835B(3835).
The message logs:

sudo cat messages|grep 'A835 (Click to View)

In http://www.linuxtv.org/wiki/index.php/DVB-T_USB_Devices/Full, says that this device looks identical to the A835 and has the same model number on the box but has a different chip inside.

It says that the correct firmware is here: https://github.com/OpenELEC/dvb-firmware/raw/master/firmware/dvb-usb-it9135-02.fw.

How can i install it?
Thank you!!
