Dear kernel hackers,
I am experiencing problems with a USB mouse: The machine boots, X
starts, I log on, everything works as expected. When I restart X or just
change to an alpha terminal and back to x the mouse does not work any
more. It does not necessarily happen the first time I do this but it
eventually will. The device is still there, ie. I can do a 'cat
/dev/input/mice' with out error but it does not do anything, there are
no characters when I move the mouse.
This does at least happen with 2.4.2, 2.4.3pre4, 2.4.2-ac17, 2.4.2-ac18,
and 2.4.2-ac20 on both Debian stable and unstable. It does not happen
with 2.2.18. So I assume that it is neither a hardware issue nor an
environment one (as in compiler version and so forth), but a problem
with the USB code itself. I think the problem might perhaps be that the
USB subsystem initialises the mouse correctly on boot with 1.5 MB/s but
tries to use 12 MB/s on
later attempts which fails. But I do not really know what I am talking
about here...
Hardware is an ASUS K7V motherboard (VIA chip set), BIOS versions
1008.01c/1008.01d/1007. It happens with both USB compiled into the
kernel and compiled as modules. A USB scanner works fine.
Please let me know if I can be of further assistance or more information
is needed.
Thanks very much,
Andree
PS: I send a message with similar contents to the linux-usb list.
Unfortunately, I got no reply so far. However, that message mentioned
only 2.4.2-ac18 and -ac17, maybe that is why. Since then I tested some
more kernels (see above).
PPS: I am not subscribed to this list, I just follow it via GeoCrawler,
so it would be great if replies could be cc'ed to me directly. Thanks a
lot.

I am working on something similar.
After a device reset a hub drops PORT_CONNECTION
flag from wPortStatus. The reason is unknown.
Unfortunately, I do not have a hardware that exibits this.
If would be invaluable someone enabled
dbg() in devices/usb/hub.c only, run the test with
BOTH working (2.2) and not working (2.4) kernels
then sent me dmesg. If you do, please tell me precisely what
you were doing to trip this.
Here is an example of a change:

Now I need something like that for a working kernel
on the same hardware.
I'll let folks know if I find anything. If anyone wants
to investigate in parallel, it would be appreciated too.

The following patch reverts the code path to that of 2.2 and fixes
the condition on the Andree's box:

I asked USB maintainers to consider it.
