Bug#469693: linux-image-2.6.24-1-686: Got better but still looses USB devs (mouse/keyb)

Package: linux-image-2.6.24-1-686
Severity: important

Hi, compared to kernel 2.6.22 it got better, now I can enable my 
motherboard's USB card reader and still write this bug-report. In
2.6.22 USB became unuable after about 30s, now it takes longer.

Of course it depends on hardware: this system has ATI SB600 and
690G chips, motherboard/barebone is ASUS Pundit. Also ...

The problem is related to heavy USB load. Example: when I write
GBytes of data to a USB disk (or Flash card or USB stick) the
kernel logs a message like "low speed usb device reset" or so.
After this time it has forgotten mouse and keyboard. It does not
help to reconnect the USB cable.

Again: with kernel 2.6.22 it was not possible (under my hardware)
to enable the card reader or the write GBytes to an USB stick.
With the new kernel it often takes 30 min or so to cause the
problem. The system used here was even booted from an SD card,
but KDE for example cannot be used, the mouse/kdb would get lost.
