Description Vesa Halttunen 2012-01-21 23:18:25 UTC

Description of problem:
Trying to use a CanoScan D1250U2 USB scanner in VirtualBox results in the error message

Failed to create a proxy device for the USB device. (Error: VERR_READ_ERROR)
Error Code: NS_ERROR_FAILURE (0x80004005)

if /lib/udev/mtp-probe exists.

Version-Release number of selected component (if applicable):
libmtp.i686 1.1.1-2.fc16

How reproducible:
always

Steps to Reproduce:
1. Install VirtualBox (VirtualBox-4.1-4.1.8_75467_fedora16-1.i686)
2. Install the VirtualBox USB 2.0 support package
3. Configure a virtual machine running Windows (7)
4. Boot up the virtual machine
5. Attach the CanoScan D1250U2 USB scanner
6. Select Devices->USB Devices->Canon CanoScan
  
Actual results:
Failed to create a proxy device for the USB device. (Error: VERR_READ_ERROR)
Error Code: NS_ERROR_FAILURE (0x80004005)

Expected results:
The scanner is usable from inside VirtualBox.

Additional info:
Seems that this has been reported elsewhere as well: http://osdir.com/ml/general/2011-06/msg20017.html

Comment 1 Vesa Halttunen 2012-01-21 23:19:44 UTC

Workaround is to mv /lib/udev/mtp-probe to /lib/udev/mtp-probe.bak but then udevd will naturally say

Jan 22 01:09:01 vesuri udevd[2455]: failed to execute '/lib/udev/mtp-probe' 'mtp-probe /sys/devices/pci0000:00/0000:00:1a.7/usb1/1-4 1 2': No such file or directory

Comment 2 Linus Walleij 2012-01-25 16:16:23 UTC

Can you provide lsusb -v for this scanner, so I can try to avoid
poking it...

Comment 4 Linus Walleij 2012-01-28 08:54:04 UTC

Hm yeah that's a *very* strange device, it is a scanner, yet it provides a vendor-specific device descriptor, which has two bulk EP and one interrupt EP, just like an MTP device :-(

I will think of something, probably I'll just explicitly blacklist Canon devices since they don't make MTP equipment for a quick fix.
