Hello Mauro
I just noticed current em28xx driver seem to be broken. When I plug
device first time it loads correctly, but when I re-plug it, it does not
work anymore but yells a lot of noise to message log. Tested with PCTV
290e and 292e both same. Other USB DVB devices are working so it is very
likely em28xx driver bug.

Easy to reproduce:
plug device
unplug device
plug device

em28xx broken 4.9.0-rc6+

2016-12-05 Thread Antti Palosaari 

Hello Mauro
I just noticed current em28xx driver seem to be broken. When I plug 
device first time it loads correctly, but when I re-plug it, it does not 
work anymore but yells a lot of noise to message log. Tested with PCTV 
290e and 292e both same. Other USB DVB devices are working so it is very 
likely em28xx driver bug.


Easy to reproduce:
plug device
unplug device
plug device

regards
Antti
