Problems with my Canon CanoScan 4400F

Hi,
I use the Free Version of VirtualHere on an OrangePi 2+
The Client is a Windows 10 PC with VirtualHere 3.2.2
The Server has Version 2.5.6

Every time i start scanning I get an error message from ScanGear
"Code : 2,155,0"

dmesg says:
[112353.980319] usb 2-1.4: reset high-speed USB device number 12 using sunxi-ehci

The scan preview works perfectly and very fast.

Has some body an idea?
