Hi All, Recently purchased one of these (0413:6a05), the instructions @ http://www.linuxtv.org/wiki/index.php/Leadtek_WinFast_DTV_Dual_Dongle appear to be wrong. Running 3.14.5 I didn't need to patch drivers/media/usb/dvb-usb-v2/af9035.c, however the tuner wouldn't work (it would be detected, but not able to tune) After a lot of stuffing around, I ended up patching it913x.c instead and everything is working well, here is my dmesg output: [ 3.981516] usb 3-2: new high-speed USB device number 2 using xhci_hcd [ 4.149345] usb 3-2: New USB device found, idVendor=0413, idProduct=6a05 [ 4.149355] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 4.149361] usb 3-2: Product: WinFast DTV Dongle Dual [ 4.149366] usb 3-2: Manufacturer: Leadtek [ 380.529378] it913x: Chip Version=02 Chip Type=9135 [ 380.530913] it913x: Remote propriety (raw) modeit913x: Dual mode=3 Tuner Type=38 [ 380.531310] it913x: Unknown tuner ID applying default 0x60it913x: Chip Version=02 Chip Type=9135
1) Older Leadtek was using V1 chips as seen on Wiki log. That device was added about ~9 months ago, Kernel 3.13. 2) It says "Unknown tuner ID applying default 0x60". Unfortunately it does not say which was the ID driver fixes. This makes me wonder if it is 0x38 which was used for V1 devices and it is not working due to wrong ID. 3) I don't have any IT9135 V2 dual device (single V1 & V2 and dual V1). So I cannot even make any tests.

AF9035 debug could be nice to see. Or any other debug which shows tuner ID. I suspect overriding tuner ID with correct ID 0x60 will make this device working. Like I did for these devices:
