Description Mildred 2014-01-27 08:19:32 UTC

Description of problem:

I have a USB mass storage device (a Polaroid XS100 HD camera, 4255:1000) that cannot stay very long connected through USB. Within seconds of being connected, it disconnects itself. I suppose that's not a problem with the device itself because it works well on Mac OS X.

Version-Release number of selected component (if applicable): kernel-3.12.6-300.fc20.x86_64

How reproducible:
always

Steps to Reproduce:
1. Plug in the device
2. It connects

Actual results:
seconds later, it disconnects

Expected results:
it should stay connected

Jan 26 23:43:41 moiraine kernel: usb 3-1: USB disconnect, device number 34
Jan 26 23:43:42 moiraine udisksd[1845]: Cleaning up mount point /run/media/mildred/9016-4EF8 (device 8:33 no longer exist)

The device stays connected 10 seconds because shotwell is scanning the device for photos and videos. If shotwell is not running doing this job, the device disconnect before that. If I manage to click the Import All button on shotwell, the device can stay connected longer.

Note, the device autosuspend is not enabled :

[root@moiraine]/home/mildred# cat /sys/bus/usb/devices/3-1/power/control
on

Comment 1 Mildred 2014-01-28 22:27:23 UTC

A workaround this problem would be the following shell script

    while sleep 1; do touch /run/media/mildred/9016-4EF8/keep-alive; done

(replace the path by whatever the mount point may be)

I also tried quirks (any one in "abilrsw") in usb_storage module but it didn't help. The procedure was:

    modprobe -r usb_storage
    modprobe usb_storage quirks=4255:1000:a (for the quirk "a")
    (restart the device)

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs.

Fedora 20 has now been rebased to 3.13.4-200.fc20.  Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.

This bug has been in a needinfo state for several weeks and is being closed with insufficient data due to inactivity. If this is still an issue with Fedora 20, please feel free to reopen the bug and provide the additional information requested.

Comment 4 Mildred 2014-05-19 19:35:56 UTC

Reopening this. The bug still happens. This is not a Fedora-specific bug, I have the same problem on 3.14.4 currently.
