Has anyone else her had the problem described in
https://bugzilla.kernel.org/show_bug.cgi?id=65021
ie complete xhci freeze when a second pctv290e is accessed with vlc.
I'm wondering if this is a problem specific to em28xx or the pctv290e
or to this kind of device (ie dvb usb).

I have seen multiple times USB3 issues and reboot is needed in order to
solve those. USB3 is simply not enough robust yet. Due to that, I will
never use USB3 ports when developing the drivers - I only test it very
quickly when driver is about ready.

Thanks to all, I applied the patch suggested by Olli Salonen and I can
now run multiple vlc's on my NUC.

It seems I managed to miss the reply-all button, so I thought that in
case someone else is looking at this I'll post it here on the mailing
list as well. This is what I wrote:
"I saw this quite a while ago on my Intel NUC (that only has USB 3
ports, so I've got no choice).
The same issue is reported here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1313279
In OpenELEC we got rid of the issue by reverting one patch, look here:
https://github.com/OpenELEC/OpenELEC.tv/commit/b636927dec20652ff020e54ed7838a2e9be51e03
"
Cheers,
-olli
