046d:c501 USB mouse does not get detected on bootup 25% of the time (USB bus reset)

I just noticed some bus resets on my external USB drive.

Could this be a HW problem? What else can I do to debug?

I have a similar problem on a Dell Latitude E4310, and it appeared around the same period (december 2010): my USB cordless mouse stopped working intermittently, and plugin it out and back in does not always solve the problem.

I attach a fragment of /var/log/syslog where
at 09:29:06 I plug the USB receiver and the mouse works, and then
at 09:29:24 the mouse stops working, with a lot of USB errors in syslog.
later on, at 09:34:41, I plug the receiver again but it is not even recognized

Some info:

Following my previous comment: this seems to be a hardware bug related to the USB receiver itself. Apparently, when I push it as far as possible into the USB plug, it goes *too* far and disconnects. If I pull it a little, it reconnects.

Still to be confirmed next time I reboot on Windows (may take a while ;-)

I confirm that in my case, this was a hardware problem with the USB receiver (same problem under Windows).
Sorry for the noise.

I have not had the problem since using the PCI USB card.

Could be HW, or a kernel incompatibility with the a8V onboard USB.

Note I had a similar problem on my shuttle PC running debian. I'd get
weird bus resets with my arduino board. Everything was fine with the
same HW in windows, and using (the same) PCI USB card solved the problem.

Please let me know what I can do to seriously test this (other than
installing windows) as now I've got two 8+ USB port machines in which I
can only use 2 ports on a single PCI card I have to swap between them.

I've upgrade 8 computers from Ubuntu 10.10 to 11.04. Two of them have the issue of the USB mouse being frozen on boot, one 20% of the time, one 50% of the time. The keyboard works on both, although at least one is not using a USB keyboard . A restart does not work. A complete shutdown is necessary, plus crossed fingers, to get it to work. I discovered last night that generally unplugging the mouse and re-plugging in the mouse generally makes it work. Also, I have less problems if the mouse is plugged in the front USB ports than if it is plugged into the back USB ports. I've tried different mice, all of which worked fine under previous versions of Ubuntu 9.04, 9.10, 10.04, and 10.10. This is a new problem with 11.04. One computer is using nVidia graphics, and the other is using ATI, so it doesn't seem to be graphics related.

b, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.

I have not had any issues in Ubuntu 12.04. When it was an issue, a
generic mouse would not work but a Logitech mouse would work. Changing
the generic mouse to a front USB port would work, but using a rear port
would not work. If the mouse was frozen, simply unplugging it and
plugging it back in would allow it to work fine. Thinking about it, my
wife may have had an issue with her generic mouse in 12.04, but if she
did, I plugged it into a front USB port.
