Can't use scanner with USB 2.0

[Floyd21_fr]

Hi,

I am using version 5.0.6 (but also tried 5.0.10) of VirtualBox with a 64 bits Ubuntu guest on a 64 bits Ubuntu host, and with the appropriate version of the VirtualBox Guest Additions installed. I have to use a scanner within VirtualBox, which uses USB 2.0 bus, but enabling 'USB 2.0 (EHCI) Controller' in guest parameters does not seem to work properly. In order to test the scanner, I use xsane to scan a document.

Selecting 'USB 1.1 (OHCI) Controller' works perfectly : the document is scanned then saved in a file with the chosen extension.

When selecting 'USB 2.0 (EHCI) Controller', scanning begins but blocks after a while, it ends with an error message on device I/O. It seems that data transfers suddenly stop, control type transfers are then sent 3 times each 10 seconds, as if the device was not connected anymore. I've tried with the latest version 5.0.10 of VirtualBox but I get the same problem.

Are there recommendations on scanner use with VirtualBox or particularly USB 2.0?

Thanks

Please reopen if still relevant with a recent version of VirtualBox.
