USB passthru not work with Mac OS X El Capitan
QEMU emulator version 2.4.50 with kernel kvm module from linux kernel 3.16.0 or 4.2.3
Since upgrading from Yosemite to El Capitan - USB passthru does not work. Note USB passthru worked perfectly with Maverick and Yosemite. I attempt to use different USB hosts. I found a patch for widows xp that had similar problem the patch was applied in 2012. Note NO problems with USB passthru with windows or linux clients. If it matters the devices that I am trying to passthru USB are smartcard reader and webcam. The devices are present in El Capitan but do not function.
These are the massages from loading the VM (El Capitan). The first two lines are from the clover bootloader. The ehci warnings are generated when loading Mac Os X El Capitan.
QEMU 2.4.50 monitor - type 'help' for more information
### These messages below started when using the clover bootloader and occur when loading El Capitan, Maverick or Yosemite.
### The bootloader is Clover version 3292

#### Below are errors when the guest host (El Capitan) is loading from qemu monitor. The messages below only occur when loading El Capitan.

the following qemu command has worked flawlessly with Yosemite and Maverick.

If anything else I can do to debug the problem please let me know.
