Description Igor Zinovyev 2017-01-24 08:03:49 UTC
I have been running Ubuntu with Linux 4.8 kernel. Yesterday I have tried switching to latest from Mainline, i.e. 4.10-rc5 and the Line6 USB Toneport (UX2 Studio) has stopped working. There is no sound, playback freezes when I select the device.

Please let me know what information you need about my system - happy to provide logs and debug info.

You can see that there are some error messages about read and write failures related to the snd_usb_toneport module.

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.

The same problem on Gentoo with vanilla-sources 4.9.4-4.9.6 with Line6 POS Studio UX1
Comment 9 Igor Zinovyev 2017-02-08 08:49:21 UTC
There is a revert that fixes this patch that is queued for the next 4.10 RC, and the full patch is going to be included in 4.11, according to this thread:
