Kai, I am a user not a dev or tech person.
I had issues with USB and a Fujitsu scanner. I am using OpenSuSE 13.1 on a new machine with a Gigabyte Z97-UD5H motherboard. He MB has both USB2 and USB3 and the BIOS supports legacy USB, EHCI and XHCI USB. What I did find is that if you look at USB connections using the following (As user or root) dmesg | grep -i usb Within the output you should find something like the following: [ 1.317162] usb 3-5: new high-speed USB device number 3 using xhci_hcd [ 1.359084] usb 3-5: New USB device found, idVendor=04c5, idProduct=11a2 [ 1.359086] usb 3-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 1.359087] usb 3-5: Product: ScanSnap S1500 [ 1.359088] usb 3-5: Manufacturer: Fujitsu [ 1.359166] usb 3-5: ep 0x81 - rounding interval to 128 microframes, ep desc says 255 microframes [ 1.359167] usb 3-5: ep 0x2 - rounding interval to 128 microframes, ep desc says 255 microframes Search out the “microframes” issue for distro. It is a known kernel issue for scanners using either USB2 or USB3. A patch is available and rolled out to OpenSuSE 13.1 over the weekend. I installed in Monday and all is well.
