Hi Everybody! First sorry for my bad english, i will try to done a good job.

I got an qnap TS-451+ NAS and a PCTV DVB-S2 Stick.

I installed the right tvheadend qpkg but there is no reciever availible in tvheadend?

is it possible to install the driver manually? or another soulution?

i tried to put the reciever into the front usb and into the back usb but there are no reaction.

i also tried to restart the nas...

TVH do not install devices it just use them,
so devices must work.

Ah okay, thank you for the fast reply.
Is there a Soulution to install the PCTV DVB-S2 Stick Drivers in the QTS OS from the NAS?
