[Qemu-discuss] qemu linux host USB passthrough firmware update fails

[Maximilian Kaul]

Hi list,
Sorry, if this is the wrong place to ask this kind of questions but I couldn't 
find a better one. If there is please be so kind as to direct me there.

I have a MacBook Air 6,2 running archlinux and I set up a qemu Windows 7
x64 guest. It works great. However, there is one problem: I have one USB
device that needs a firmware update, and there are only updaters for
Windows and OS X :(

My usual approach would be to just add the device to my Windows guest via

-usbdevice host:auto:*:*:0x2514:*,id=jawbone

where 0x2514 is the vendor ID. This works for all my other USB devices.
But in this case, what happens is the following:
The device gets discovered by the guest and the updater starts. I think
that at some point it puts the device in a special mode to update the
firmware and then the updater fails. lsusb on the host does not show the
device at that point. The only way I have found to make the device
visible again is to unplug and then replug it.

qemu monitor displays this error message when I try do update the device:

QEMU 2.0.0 monitor - type 'help' for more information
(qemu) libusb_release_interface: -4 [NO_DEVICE]
libusb: error [_open_sysfs_attr] open 
/sys/bus/usb/devices/1-2/bConfigurationValue failed ret=-1 errno=2
libusb: error [_get_usbfs_fd] File doesn't exist, wait 10 ms and try again

libusb: error [_get_usbfs_fd] libusb couldn't open USB device 
/dev/bus/usb/001/052: No such file or directory

I have tried to add a USB controller and attach the device to that, with
the same result:

-device piix3-usb-uhci,id=uhci (it's a full speed device)
-device usb-host,bus=uhci.0,vendorid=0x2514,productid=0x0002,id=jawbone

I use qemu 2.0.0-4 with 3.15.1-1-ARCH 64 bit kernel; all software is 
(archlinux)-up-to-date.

dmesg outputs this:

Is there anything else I could try?
Thanks for your help!
