I just noticed that after I applied the latest updates (apt-get dist- ugrade) to my Ubuntu 14.04 system that USB redirection is now failing on THIS system as well - just like the 14.10 system failed.
FWIW, I do not see any apparomor denial messages in /var/log/syslog or anywhere else. So far I've not found anything to indicate why passthrough failed, seems like a silent failure whatever it is. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1392504 Title: USB Passthrough is not working anymore Status in QEMU: New Status in qemu package in Ubuntu: Incomplete Bug description: After upgrading from Ubuntu 14.04 to Ubuntu 14.10 USB passthrough in QEMU (version is now 2.1.0 - Debian2.1+dfsg-4ubuntu6.1) is not working any more.
