Vojtech, linux-usb folks-
It appears that you may be responsible for maintaining various USB human
interface device drivers. If this is not the case, please disregard
this message.
I'm having a problem with a Sony Vaio laptop (UHCI) and a Microsoft
Intellimouse. The mouse works great from first insertion to a suspend
or disconnect and then fails to work.
This happens with kernel 2.2.15 and usb-2.3.99-pre7-1-for-2.2.14.diff
There are others who have this problem (and have posted to the
[EMAIL PROTECTED] mailing list). Paul Ashton <[EMAIL PROTECTED]>
posted a patch to that list but I can't get it to install on this
kernel/usb stack combination. I've attached the patch below.
Is this a known issue? Has it been resolved? The mouse works great up
until a suspend, and its a shame to have to reboot to get it to work
again.
Thanks for your time and your software,
-c
