http://bugzilla.opensuse.org/show_bug.cgi?id=1205737 http://bugzilla.opensuse.org/show_bug.cgi?id=1205737#c4 --- Comment #4 from T Adams <timothyadams@ymail.com> --- I download the extension pack and guest additions from https://download.virtualbox.org/virtualbox/, don't remember ever having gotten them another way. The "One of the USB devices attached to this computer has malfunctioned" message comes from within the Windows 7 client itself. I use two scanners through the Win 7 client, and the problem affects both. I again restored the working 6.1.40 snapshot, and will post again here if I do more troubleshooting. I then can try different USB configurations in Win 7 and see what lsusb shows for the scanner in Tumbleweed, as you suggest. I understand that I may be in the lurch if other users aren't affected by this issue. There may be something odd in my setup. Larry, thanks again for your response, and for your work on VB for openSUSE. -- You are receiving this mail because: You are on the CC list for the bug.
