USB can randomly dis/reconnect and that is normal. The lockup issues could be related to other drivers and/or X fighting over the hardware. On Apr 25, 2009, at 13:16, E Johnson wrote:

Tonight I am being reminded several times per hour that something weird is happening here. I have a mouse and keyboard USB disconnect problem that has been hanging around for a couple of years now.

Across the room where my old computer sits quietly running, the red light in the mouse keeps flashing as it goes off then comes back on, even though this computer is idle. So I checked /var/log/messages, and sure enough, messages appear there that correspond with the times the red light flashes.

Messages like these crop up regularly and often in /var/log/messages

This PC is running Debian Lenny kernel 2.6.26-1-686. Same thing often used to happen with the USB keyboard, too. Now I'm using a PS2 keyboard in this PC, which does not result in these disconnect messages, but still seeing these messages about the mouse. Sometimes this happens over and over again many times within a short period of time (several times/minute).

There were lockup problems related to this problem when I was running Etch, after this keyboard or mouse USB disconnect thing had disconnected and reconnected some large number of times, I think it was well over a hundred times. Keyboard and/or mouse would no longer accept input, forcing me to have to ssh in and reboot it, or if I couldn't do that, had to hard reboot. Restart X is not enough to fix this. This has happened with various different mice and keyboards.

So we installed a USB card, thinking this might be a hardware problem with the USB ports, but no, the same problem crops up no matter if the mouse or keyboard is plugged into the card, or into the USB ports in the case.

Then we thought it might be a problem in Etch, so we upgraded to Lenny. But it still happens. Also happens in Ubuntu.

The latest issue (see below) was a long string of these disconnect/reconnects, then a lockup of the mouse and I believe keyboard. Had to ssh in to stop the problem (by shutting down). This new build is using my used hard drive, but I don't think that is relevant. Below is only a small piece of var/log/messages, where the problem seemed to change after several hours from the familiar mouse disconnect/reconnect, to something else. These mmessages were repeated many times (over a hundred):

Had same problem in this new PC, running a recent Ubuntu Hardy (8.04) install. This PC is only a few weeks old, now with a fresh install of Lenny in its own partition. Only the hard drive and the DVD drive are not brand-new.

I possibly (maybe?) solved the keyboard issue in this PC by specifying the correct type of keyboard in Settings > Peripherals > Keboard (in KDE). Not sure if it's really gone or not. But now getting hundreds of messages about the mouse, as above.

Computer 3. It's also happening in my daughter's computer, that has the exact same motherboard and almost the same CPU as computer 2. Hers is running Ubuntu 8.04 2.6.24-23.52 (running Gnome), just updated last week. She has never complained about any lockup problem, but she reboots more often than I do.

Computer 4. I believe this also happens in the laptop, a Dell Inspiron 1525n, running (now) Ubuntu Hardy (this came with Ubuntu 7.10 pre-uinstalled). Cannot post /var/log/messages from this today, since this laptop is away with daughter. But the same messages appear in that one, too.

Has anyone run into this before, and if so, did you get it fixed?

Is it normal for USB to disconnct/reconnect repeatedly, many times per minute?

That sounds fishy, but possible

Is that still considered random and normal? That's what we have here, in the three different computers that I have access to today. Not a few times, but zillions of lines in /var/log/messages. It's worst in the older PC.

The mice mostly have been pretty standard Logitek versions, nothing fancy or unusual.

How can I find out if the lockup is caused by "X fighting over the hardware", or by drivers?

Kernel version, distro, output of lsmod? It looks like you use different event drivers in each setup, but if you know which uses which, that could help

Thanks, Liz J

Never had jumping mouse that I recall. My (new) PC using a little KingWin mouse (no longer available); "old" PC using old Logitek; have used other Logitech including one that's now connected to the laptop (the one I could not post /var/log/messages for). Daughter PC using Logitech mouse since her light-up one died. These Logitech mouse are low-end, 3 buttons. Two are identical, that can work I believe a 5-button. Can get mfr part numbers if needed. Keyboards are miscellaneous, mainly slim-type, inexpensive Rosewill (Newegg's own brand) which these seem to be mfr by "Chesen." Can get mfr part numbers if needed. Will try the newer kernel per J.

2.6.28 is not a great release. Fedora skipped over it and went right to 2.6.29.1 which is the latest stable kernel.

Odd. 2.6.28 was unproblematic from the traffic on LKML. I see many more complaints about 29. Maybe Greg ported good patches into stable. What was Fedora's beef?

Hmm... Ubuntu (tried against 8.10 x64, 9.04 i386 liveCD & x64) (and Fedora 10 x64) have problems with sound with my recent HP DV4-1222NR laptop. I suspect my audio setup is similar to E. Johnson's.

Problem is with alsa-driver. When I compile from source it works, until the kernel changes.

Well, that's the nature of an unstable kernel API :P

Even then the mute & volume "smart keys" do not have the desired effect, so I have to use the icon or menu. Gnome keyboard shortcuts gui is poorly documented - there is no man page, no indication what config file gnome-keybinding-properties corresponds to.

How do I change the action "volume mute" to affect the proper device?

There are lots of ways to do that. Gnome and KDE are a bit mystical (and don't work). Google for "evtest", which is a program that can look at a file in /dev/input/ and tell you what key/keycode/etc was pressed. Also, xev might be enough for you to find out what key it is, and map that into whatever application you use.

FWIW, I don't believe that this (bizzare mouse behavior) is a Linux issue.

I have a wireless logitech keyboard/mouse at work hooked up to a thinkpad running XP, and find that sometimes the mouse goes haywire. It seems to be due to wireless interference (there's a crapload of that in my office).

I find that if it's particularly bad, I can force it to swtich channels and reassociate by hitting the connect button on the receiver followed by the connect button on the mouse (order is important, as just hitting the connect button on the mouse will appear to reassociate, but will not change the channel).

Also I've noticed that these problems tend to be more likely to occur/are worse when the mouse is running low on battery (which it eats through like candy, but that's another gripe).

IIRC this is an issue with wired devices. It may not be a kernel issue at all. Sometimes, hardware is just flakey. The real test would be to use a different brand of mouse for a while and see if the errors stop.

Hope that helps,

It's happened across office moves (in the same building), so I'm less inclined to believe that it's the location of the receiver specifically. Since my company creates wireless devices, we've just got a ton of interference all the time (I'd estimate that at any given point in time we have around 100 APs talking in a 100 yard radius. I've got four in my office, not to mention the four stations). Also it's fine most of the time ... when I replace the batteries, it chooses a new channel often, and is borked until I get it to move to a clear channel, and then it works fine for another month or two until the batteries die. Funny enough ... the keyboard just works ... I've not changed the batteries in two years, and never had interference problems ... hooray for super low-bandwidth applications :) Cheers, Lee On Tue, Apr 28, 2009 at 1:31 PM, Richard Klein wrote:

FWIW, I don't believe that this (bizzare mouse behavior) is a Linux issue.

I have a wireless logitech keyboard/mouse at work hooked up to a thinkpad running XP, and find that sometimes the mouse goes haywire. It seems to be due to wireless interference (there's a crapload of that in my office).

Have you tried relocating the receiver?
