assigning complete usb controller to vm. scanner device works but very, very slow

[Steffen Hartmann]

Hello,

I've assigned my scanner (and the complete usb controller) via this description
https://www.qubes-os.org/doc/assigning-devices/ into a virtual machine.

I can use scanimage to use the scanner but it takes about 5 minutes to scan a page.
Everything works however.

Using Scanimage -L also works but also a long delay (30 sec).
This is true for debian 8 and also for fedora 23 and fedora 24 templates.

I also updated to kernel 4.8.12-12 (insde VM) but no change.

OS is Qubes 3.2 running the above kernel in DOM0
PC: Dell 5500 precision

This is probably a compatibility issue with that particular scanner
model. I've used a couple of different scanners in Qubes VMs and
haven't noticed any significant difference in scan times.
