Title:
Crash while connecting phone via USB: usbfs did not claim interface 0
before use
Status in linux package in Ubuntu:
Incomplete
Bug description:
After plugging in my phone via a USB cable, my system slowed and soon
became non-responsive, even to Ctl+Alt+F1 and Alt+SysRq+[SUB] keys. At
some point I unplugged the phone. I let the computer sit for an hour
to see if anything would happen; the GUI continued to be displayed,
and it continued to be unresponsive to all keyboard and mouse input.
My phone tends to have a poor and inconsistent USB connection. While
that's a problem, it shouldn't be the kind of problem that leads to a
system crash.
I plug this phone in regularly using the same cable, and this is the
only time it caused a crash. It usually connects via MTP without
problems. It is conceivable that some other application caused the
crash, or reduced the available memory enough to expose a bug in
usbfs. However, the 640,442 error messages in /var/log/kern.log makes
me think this is a usbfs problem.
I'm not sure where to report this bug, as the logs indicate it is
related to usbfs, which this says has long-since been deprecated and
removed from Linux: https://askubuntu.com/a/388062
