Hi all,
I have a PCTV nanostick T2 290e which is supported in the latest linux kernel - I have used this device on OpenELEC no problem.
However I have installed 'xbian-package-tvheadend' and gone to the web interface on another computer but the device is not shown - I have made sure it has power and is directly plugged into the pi.
dmesg shows:
Some others seem to think that's it's something to do with the Kernel version - I am running 3.12.7+

Any idea friends?
I have a PCTV nanostick T2 290e which is supported in the latest linux kernel - I have used this device on OpenELEC no problem.

dmesg shows:
