Description László Attila Tóth 2005-08-20 10:58:10 UTC

I use usb mouse and keyboard, which worked in suse 9.3, but now after their
disconnect, I cannot use them again. The system doesn't see them (in lsusb).

/etc/sysconfig/hotplug is the same as in 9.3

In /var/log/message:

Vojtech, any clue?

Comment 2 Vojtech Pavlik 2005-08-22 08:59:54 UTC

It seems like the connect events are not being detected, which is surprising.
Are there any messages in the kernel log when the devices are plugged in?

Comment 3 László Attila Tóth 2005-08-22 09:33:56 UTC

dmesg output:
usb 1-1: USB disconnect, address 2
input.c: calling hotplug without a hotplug agent defined
(no more messages after plugging in)

After a suspend to disk /resume it works, but on the running system it doesn't.

Comment 4 Vojtech Pavlik 2005-08-22 14:58:29 UTC

The messages above show that not just the USB devices were removed, but
also USB modules for the host controller were removed from the kernel.
Can you verify that is what happens? In that case some hotplug script is the
culprit - if an USB host controller module isn't present, it can't detect
a new USB device being plugged in, obviously.

To check if USB HCD modules are loaded, use

lsmod | grep hcd

Comment 5 László Attila Tóth 2005-08-22 15:46:53 UTC

~ # lsmod | grep hcd
uhci_hcd               32016  0
usbcore               112640  4 uhci_hcd,usbserial,usbhid

The same before and after unplugging my mouse. But when the mouse is not plugged
in, I still can use my usb keyboard.

Other: Now both of them is unplugged, lsusb has a problem

Comment 6 Vojtech Pavlik 2005-08-22 15:51:30 UTC

Yes, I know about the usb.ids bug. It's not relevant to your problem.
You can just remove the offending line(s) in the usb.ids file.

Comment 7 Vojtech Pavlik 2005-08-22 15:53:00 UTC

Do I understand you correctly that the issue doesn't manifest itself until
you remove both the keyboard and mouse, or is unplugging & re-plugging the
mouse while keeping the keyboard plugged enough to make the mouse stop
working?

Comment 8 László Attila Tóth 2005-08-22 16:25:35 UTC

If either mouse or keyboard is unplugged, I cannot use them again. It doesn't
depend on the state of the other device. It can be plugged or unplugged, the
issue is the same.

Comment 9 László Attila Tóth 2005-08-26 08:34:08 UTC

In beta3 it works.

Comment 10 Christopher Lovett 2005-10-11 02:58:00 UTC

I'm using 10.0 GM and I can boot with my mouse plugged in, but once removed it
no longer works.  Dmesg gives this output:

   hub 2-0:1.0: Cannot enable port 1.  Maybe the USB cable is bad?

This is repeated over and over until the device is removed.  Like I stated
though, the mouse works perfectly if entered at boot-time.

Comment 11 Vojtech Pavlik 2006-01-11 10:47:39 UTC

Ok, if it works in beta3, I think we can close this. Christopher, your problem
seems different, please open a new bug for this if needed.
