[Karmic] USB Hotplugging Doesn't Work

[Jonathan Reeve]

Karmic never recognizes any USB device I plug in after boot. That means, if I have my USB mouse plugged in at boot, it will work, but if I unplug it and plug it back in, it won't work. Same with flash drives and my USB printer. Dmesg doesn't show anything, and there's no system log (that I know of) that registers anything about this.

I don't have this problem with the live CD for some reason.

I've tried reinstalling Karmic a few different times, using slightly different configurations each time, but nothing seems to work.

I tried unplugging and re-plugging my mouse a few times during boot to see what happens, and I discovered that hotplugging stops working about halfway through the boot process, before the login screen. So I don't think it has anything to do with permissions, because this all happens before I log in.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command, as it will automatically gather debugging information, in a terminal:

apport-collect 445129

This will help us to find and resolve the problem. Bear in mind that you may need to install the python-launchpadlib package from the universe repository. Thanks in advance!

I tried running apport-collect 445129 but I think I gave it the wrong permissions, and now I'm getting this error:

From karmic ~beta6, some USBs worked on plugging, some didn't.
Now (stable up-to-date karmic), nothing seems to work.
I tried now to (re)connect:
* Two disk-on-keys - didn't even appear in dmesg or lsusb.
* Disconnected and reconnected an external mouse (SIGMACH1P U+P) - nothing (or only disconnect?) in dmesg, didn't re-appear in lsusb.
* Disconnected and reconnected an external keyboard (KEYBOARD USB KB) - disconnect noted in dmesg and Xorg.0.log; nothing on connect, didn't re-appear in lsusb.
* Tried netbook's Fn shortcuts to toggle webcam off and on (it sits on internal USB) - nothing in dmesg (except unrecognized scancodes, but these messages also appeared when the shortcuts did work in intrepid), webcam stayed listed in lsusb the whole time.

Attaching lsusb -v, dmesg, Xord.0.log after the experiments.

[Beni Cherniavsky (cben)]

intresting:

> sudo lsusb -v > sudo_lsusb_-v.txt
can't get device qualifier: Cannot send after transport endpoint shutdown
can't get debug descriptor: Cannot send after transport endpoint shutdown
cannot read device status, Cannot send after transport endpoint shutdown (108)
can't get hub descriptor: Cannot send after transport endpoint shutdown
can't get device qualifier: Cannot send after transport endpoint shutdown
can't get debug descriptor: Cannot send after transport endpoint shutdown
cannot read device status, Cannot send after transport endpoint shutdown (108)

there is also stuff in dmesg now (next attachment) about the failures of lsusb.

The same to me. HP Mini 2140 with Karmic installed doesn't attach USB mouse after boot.

This may be a duplicate of #455408.

[Beni Cherniavsky (cben)]

Thanks Jesse!
The behaviour I see is exactly as described in bug #435352 (of which #455408 is a duplicate).
The fix described there of blacklisting uvcvideo worked!
No webcam (which didn't work anyway in karmic) but USB hotplugging works (mouse, kbd, disk-on-key)!

Jonathan, I see you also have MSI U100 - the fix very probably will work for you too.
