Christopher (penalvch): Thank you for your reply. I am not totally sure if you reply means that I need to install Ubuntu (instead of Mint 17) to file the bug?
As a desperate attempt I bought a USB2.0 PCI-e card and installed it in my motherboard (Syba PCI-express USB2.0 5 port host controller card). This has SOLVED my problem (for $23). If I plug the Fujitsu SnapScan S1500 back into a motherboard USB 2.0 port I get the exact same error as before (bellow). In summary: I have “solved” this recognition problem of the Fujitsu SnapScan S1500 in both Mint 16 and Mint 17 with both GA-Z87X-UD3H Gigabyte motherboard and MSI B85M-G43 motherboard. My solution is to buy a USB2 PCI-e board. From the posts this happens the same way in Ubuntu and Mint (I searched but did not find any Mint forum addressing this). Contrarily to what I previously thought this does not seem to be related to USB 2.0 vs USB 3.0 (I need a PCI-e USB 3 card to be sure). Hope my long report is of some help. Let me know if I can help further without a new install. $ dmesg [ 872.748353] usb 6-6: Product: ScanSnap S1500 [ 872.748354] usb 6-6: Manufacturer: Fujitsu [ 872.748473] usb 6-6: ep 0x81 - rounding interval to 128 microframes, ep desc says 255 microframes Again, some system info: Linux sky 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux, Mint 17, Cinnamon 64 bits 2.2.16 Motherboard: Motherboard MSI B85M-G43 Intel I7-4770 CPU Graphics card and driver: NVIDIA GK107 GeForce GTX650 Nvidia 331.38-0ubuntu7.1 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1102797 Title: 04c5:11a2 Fujitsu ScanSnap S1500 does not work on USB3 ports Status in “linux” package in Ubuntu: Incomplete Bug description: I have a Fujitsu ScanSnap S1500. This scanner worked fine in 12.04, 32-bit. I wiped the hard drive and installed 12.10, 64-bit, fresh. The scanner has not worked since and I can't figure out why. I'm not quite sure which package to put this bug in. The wiki says any hardware problems get assigned to the kernel, but my scanner shows up in lsusb and shows up in /var/log/udev. That makes it sound like the hardware is getting seen. What doesn't work is sane-find-scanner, xsane, simple-scan, or gscan2pdf. Nothing that actually interfaces with the scanner works. Yes, I'm in the scanner and saned groups. The USB device ID is 04c5:11a2. The device is in /lib/udev/rules.d/40-libsane.rules. The backend is enabled in /etc/sane.d/dll.conf.
