[Qemu-devel] USB ehci passthru issues

[Peter Lieven]

Hi,


I have a DVB-S2 tuner that is passed to a vServer running Qemu via EHCI.

After some time of operation the tuner always fails with the following errors 
in the log:

Feb  7 15:12:17 tvheadend-neu kernel: [ 1346.926238] usb 1-1: failed=-75

Feb  7 15:12:19 tvheadend-neu kernel: [ 1348.925886] usb 1-1: dvb_usb_v2: 
usb_bulk_msg() failed=-75

Feb  7 15:12:17 tvheadend-neu kernel: [ 1346.926238] usb 1-1: failed=-110

Feb  7 15:12:19 tvheadend-neu kernel: [ 1348.925886] usb 1-1: dvb_usb_v2: 
usb_bulk_msg() failed=-110


Has anyone seen this before? The error -110 is repeated about every second.

I already tried to blacklist the tuner drviers on the host, but that didn't 
help.


Thanks,
Peter
