[Bug 1312594] Re: 14.04 won't detect common USB scanner

Found a workaround: The error message rounding interval to 128 microframes, ep desc says 255 microframes seems to be caused by the xhci driver that handles USB3.0 ports. Using a USB2.0 port works fine. The same happens with some memory sticks and my Epson Perfection V10 scanner. Will go and

[Bug 1312594] Re: 14.04 won't detect common USB scanner

Did try to make my scanner work with the latest upstream kernel. Seems like the problem is valid there, too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1312594 Title: 14.04 won't detect common

[Bug 1312594] Re: 14.04 won't detect common USB scanner

Did test if the problm persists with the latest vanilla kernel (it does) so I sent a bug report via mail to the maintainer of the xhci kernel driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

[Bug 1312594] Re: 14.04 won't detect common USB scanner

I can confirm that scanning seems to be working when using the USB2.0 port on my machine. I can't believe I didn't try that. Thank you for the advice - hopefully it will be addressed with the upstream kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which

[Bug 1312594] Re: 14.04 won't detect common USB scanner

I am experiencing the same problems with an HP Laserjet 1220 scanner. From what is listed below, there seems to be some problem starting with sane_open(). The first time it runs on a new device it claims to be successful, but that message is never repeated until the device is removed and

[Bug 1312594] Re: 14.04 won't detect common USB scanner

Same problem, in my case with a USB-attached Canon Canoscan N650U (an ancient, well supported scanner, that was working just fine on 12.04LTS). $ lsusb Bus 002 Device 002: ID 174c:3074 ASMedia Technology Inc. Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 012: ID

[Bug 1312594] Re: 14.04 won't detect common USB scanner

I'm confused about what is the sane frontend or backend, or whether I should download/install another frontend or backend, if there is one. I'm not sure, but from the following, it seems like, on Ubuntu, that sane is the frontend, and sane-utils is the backend (???) . dpkg -l | grep -i sane ii

[Bug 1312594] Re: 14.04 won't detect common USB scanner

I'm having a similar problem. I have an old 32-bit Debian laptop on which my scanner is working fine, and a new 64-bit Ubuntu 14.04 laptop on which the scanner is not working. The scanner is connected via USB cable. It is part of a Brother DCP-8155DN (multifunction black and white laser

[Bug 1312594] Re: 14.04 won't detect common USB scanner

I've got Canon CanoScan LIDE 25 scanner that stopped working following Ubuntu 14.04 upgrade. The scanner is recognized by system (kernel and sane-find-scanner) and shows up it Simple Scan options dialogue. Yet the scan action fails with the scanner not powering itself up and not doing anything.

i also have an out of the box fujitsu fi-6110 which function perfectly on 12.04 and i believe new install of 13.10 but the upgrade of 13.10 to 14.04 made the scanner invisible to sane-find-scanner and sanimage -L. also noted udev did detect the scanner as above and shown in the logs below,

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people

Assigning to libsane as only scanning is impacted. This might possibly be related to another package though. ** Package changed: ubuntu = sane-backends (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.
