none needed The QT1010 in this device has it's problems. If you get no or poor signal on Linux, that's "normal". You can try lowering the signal strength from your antenna, remove signal boosters and/or buy an attenuator. Or buy a device with better support.

Making it Work

Works out of the box since 2.6.23. However, the combination QT1010+ZL10353 is problematic. If you are having problems with reception, try reducing the signal strength. Disable boosters and/or use an attenuator.

Firmware

None required.
