Hi, I have a problem with a USB device (4255:1000), running various kernels from 3.12.6 (Fedora) up to 2.14.4 (ArchLinux). When I connect the device, it appears all right. But after a few seconds of idle, it disconnects itself.
When I manage to use the device (read or write files to the mounted filesystem) it stays connected. I published bug reports here: https://bugzilla.kernel.org/show_bug.cgi?id=76511 https://bugzilla.redhat.com/show_bug.cgi?id=1058194 The kernel log with kernel 3.14.4 shows a stack trace (bug report on kernel.org) that didn't happen on earlier kernel version (3.12.6, Fedora bug report). Note, usb autosuspend is off for that device: cat /sys/bus/usb/devices/1-6/power/control on Do you have an idea what's wrong with this device. It works well on Mac OS X and Windows. Thank you, Please keep me to the Cc as I am not subscribed to the list.
