[sane-devel] Fwd: Re: SANE project

[Chris Glasoe]

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.
