DVB-T stick with Afatech AF9035 chipset. On plugging in, dmesg gives:

[ 35.464061] usb 1-4: new high speed USB device number 2 using ehci_hcd
[ 35.607974] usb 1-4: New USB device found, idVendor=07ca, idProduct=a835
[ 35.610036] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 35.612210] usb 1-4: Product: A835
[ 35.614323] usb 1-4: Manufacturer: AVerMedia TECHNOLOGIES, Inc
[ 35.616394] usb 1-4: SerialNumber: 3030833016220

No firmware loading despite I copied dvb-usb-9035-01.fw to /lib/firmware, because there is no support yet in the mainline kernel for AF9035 chipset. I found a DKMS package on http://ppa.launchpad.net/mariodebian/dvb-usb-af9035/ubuntu/pool/main/a/af90xx-dkms/ and built it after adding the device's ID (07CA:A835) to dvb/dvb-usb-ids.h, however it didn't work out and I still get the same dmesg output.

Tested on fully updated Debian Sid.
