Hi, I recently bought a Tevii S650 USB DVB-S2 device (dw2102 driver). But when i connect it, my Desktop seems to get some HID inputs (some random keys are typed in a terminal). Pretty strange, but I set disable_rc_polling=1 for dvb_usb to get rid of this problem as the pattern reminded me of a Remote. But now i get oops (tried on two different linux systems). I verified the Hardware on Windows 7 and it works fine... Currently i'm using 4.12.0-1-amd64 (debian testing), but I checked everything 4.9-4.12(Debian) and even 4.13 (vanilla) has the same problems. Can anyone help me, or has some suggestions how to further debug? [ 11.106776] dvb-usb: found a 'TeVii S650 USB2.0' in warm state.
