Comment # 3 on bug 1205737 from Larry Rainey

Is the failure in Linux VirtualBox or Windows 7 Guest Additions?

The Windows guest additions are not part of the Tumbleweed Virtualbox as they
are copyright by Oracle.

If it is the Windows guest additions - they are now done by the OpenSUSE team
but by Oracle Virtualbox and they need to get the logs from you to see what
failed. The Oracle Virtualbox forum is the place to put the bug information in
the Windows guests section.

I am wondering if the scanner is not freeing from the Linux driver when the
Devices > USB > USB Settings selects the scanner.

I don't have a USB scanner to test with.

I test with USB camera, USB to nvme converter, USB to SSD converter, USB 2
flash drive, and a USB 3 flash drive. They all work in windows 10, 11 and back
in Tumbleweed.

I am trying to remember Windows 7 - I think it had USB 3 support.

Have you tried the USB 2 in the Windows 7 config instead of the USB 3 to see if
it is the Virtualbox USB pass thru?

What does the lsusb show for the scanner in Tumbleweed?
