This a upstream kernel bug. Its been recently reported and confirmed on the linux-usb maillist: http://comments.gmane.org/gmane.linux.usb.general/110579
Its is extermely annoying to say the least. Its affects my scanner, an epson 1300i also. Interestingly its been reported working on a CentOS6 machine: http://www.openfusion.net/linux/scansnap_1300i and on Arch: http://kabads.monkeez.org/2014/07/using-fujitsu-scansnap-s1300i-on-arch-linux-going-paperless/ and on a Rpi: http://www.splitbrain.org/blog/2014-08/23-paper_backup_1_scanner_setup So I would surmise that they are all either running on machines without xhci controllers or on kernels which are not affected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1102797 Title: 04c5:11a2 Fujitsu ScanSnap S1500 does not work on USB3 ports To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1102797/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
