The switch is done in the PCI initialisation. Blacklisting the module doesn't help. You need to build a kernel without XHCI. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

When I connect it to a USB3 port, scanimage -L doesn't work correctly. There are three possible outcomes: 1 - it reports the scanner correctly and then hangs for a very long time (this only happens on the first attempt after it is connected). 2 - It hangs for a while and then says that no scanners were identified. 3 - It immediately says that no scanners were identified. When connecting the scanner to a USB3 port, sane-find-scanner as well as lsusb always detect the scanner correctly (i.e., repeatedly, even after scanimage -L failed to detect the scanner). When connecting the scanner to a USB2 port on the same machine, everything works fine. I see this behavior both on my desktop and laptop. My desktop has an Etron EJ168A USB3 controller. I am not sure what is in my laptop. But the behavior is clearly not specific to the Haswell chipset. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

http://bugzilla.novell.com/show_bug.cgi?id=856794 Hans-Peter Jansen changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hpj@urpla.net --- Comment #15 from Hans-Peter Jansen --- This is a real showstopper. After changing my primary system to a haswell based one, that only provides xhci driven usb devices. Interestingly, this problem bites primary people, that are using a scanner with linux. Mine is an Epson Perfection 4490 Photo. The xhci driver throws this message: rounding interval to 128 microframes, ep desc says 255 microframes resulting in a non operational device. The only solution, I found so far, is adding a USB2 only extension card: http://www.startech.com/Cards-Adapters/USB-2/Card/4-Port-PCI-Express-Low-Pro... My new board is an Asus Z97-A. To cap all this, its UEFI BIOS is confused from time to time due to this card (2 of 3 reboots), where it fails to detect my keyboard properly, resulting in a additional beep during POST, and missing keyboard control within grub2. If I need keyboard control for grub2, I have to turn off the scanner before reboot. Oh well. What I really dislike here is the way, how this issue is handled. There's some discussion on linux usb ML, but no solution. -- You are receiving this mail because: You are on the CC list for the bug.
