I think it is related to Apparmor, I see the following lines in
/etc/syslog:

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. Already tried to remove and attach the USB devices. I use 1
  USB2 HDD  +  1 USB3 HDD to a virtual linux machine; 1 USB2 HDD to a
  virual FNAS machine and a USB 2camera to virtual Win7 machine. All
  these devices are not working any more.
