[9fans] USB mouse doesn't like being unplugged

[9fans] USB mouse doesn't like being unplugged

[Matt Adams]

Folks:

I am using usb/kb to provide support for my keyboard & mouse which are
plugged into a KVM.  They both seem to work well enough.  I still have
to use a PS/2 keyboard to input the mount point & user but at least
things start working when rio is available and I can do the "usb/kb"
thing.

My problem is when I switch to another machine and then come back to
my plan9 installation: the keyboard keeps working but the mouse stops
responding to all input.

I also get the following error when this happens:

usb/kb: mouse: read: usb endpoint stalled

Does anyone know how if it is possible to make the mouse portion of
usb/kb somewhat more resiliant to disappearing/reappearing?  I would
have hoped that this were possible seeing as how it's USB.


Thanks in advance,

Matt

Also, since I'm a newbie it just occured to me that if it isn't easy
to make usb/kb live with the mouse going away & coming back that it
might just be possible to unload & load usb/kb when I need it -

Actually, this would be a pain in the butt since I'd have to revert to
my PS/2 keyboard but that may be better then having to restart the
machine when I want to get my mouse back :-)

you can kill off usb/usbd and usb/kb and restart
them and that usually works.  i got usb/kb sort-of
reliable for replugging with intel usb.  but i couldn't
sign up for supporting that configuration.

Oddly enough the keyboard seems to work after the switch (most of the
time) but the mouse never does.  Use of usb/kb -k and usb/usbmouse
(and successive restarts of usb/usbmouse) seems to do the trick most
of the time but it is ungainly to say the least.

Would you be willing to provide an example of a script that I could
start from profile (or whatever is reasonable) - something that would
check for a stuck usb device and restart the appropriate components?
I would give this a shot myself but I am newbie enough that I think it
would take me a long time to get to that point.

In any case, thanks for your assistance -

had a kvm switch once and it sucked even for just ps2.  now i find it
rare for the need to access the real keyboard/mouse of a machine.
expecialy in the case of plan9 where you can use drawterm or vnc.

in case you want to use 2 monitors and only switch for keyboard/mouse
input you can use the synergy client [1] for plan9.  (expecting you are
using window/unix on the other machine)

Cinap's synergy client is working very well for me where I run the
Synergy server on Windows (although I do keep a PS/2 keyboard plugged
into my Plan 9 machine to specify the install location and username at
boot time).  Even copy/snarf and paste works between machines which is
a nice trick.

The only fiddly bit is configuring the Synergy server on Windows where
there is a bit of redundancy.  See the attached screenshots.  AMD is
my Windows machine, everex is my Plan 9 box.

The synergy server (for Unix, Windows and OS X) can be found at
http://synergy2.sourceforge.net/.

Usb code does not handle hot plugging.

If you happen to have uhci I can help u off list.
