My testing, so far, results are as follows: Using a fully updated fresh install of a TW VM without installing any Guest Additions in guest. 7.0.4 additions in host, using xsane for scan program: openSUSE Tumbleweed host - Tumbleweed guest - USB 3 port: Everything works. openSUSE Tumbleweed host - Tumbleweed guest - USB 2 port: Everything works. Both ports initially got a garbled input and had to be disconnected and xsane restarted. After installing Guest Additions 7.0.4: openSUSE Tumbleweed host - Tumbleweed guest - USB 3 port: Everything works. openSUSE Tumbleweed host - Tumbleweed guest - USB 2 port: Everything works. Again, it took some fiddling to get the correct output from xsane. With a Windows 7 VM, the device manager reports that the driver is unable to start for either USB2 or 3. With a Windows 10 VM and using the driver for Windows 8.1, which is reported to work, the Device Manager says the "The device reported an I/O error." I reinstalled the driver and the Guest Extensions without any effect. To test if the problem was that suspect Windows driver, I installed the driver and software for an Epson V600, which works on my wife's Windows 10 machine. Again the I/O error resulted. It appears that the problem is only with Windows, other than the problems getting a correct connection in Linux, but that may not be new. I have only done scanning with the host until this test. -- You are receiving this mail because: You are on the CC list for the bug.
