Dear Maintainer,

My USB mouse intermittently stops working (pointer not responding to it,
but responding normally to the internal trackpad); this has been
happening for at least 1-2 months (possibly since install), but has been
unusually frequent for the last few days.

When not working, the mouse continues to appear in lsusb and
/dev/bus/usb, but sudo cat /dev/input/mouse0 gives nothing; nothing
appears in kern.log.  It can be made to work again by a suspend/resume
or hibernate/resume cycle, or by physically disconnecting and
reconnecting it.

Unlike #780923, it only ever affects the mouse, not the (also USB) keyboard.

The attached is a usbmon log (sudo cat /sys/kernel/debug/usb/usbmon/2u)
of this bug.

Sometimes (but not in this log) the internal trackpad is also affected,
after which unplugging/replugging the external mouse fixes only the
mouse, but suspend/resume fixes both.  As I do not normally use that
trackpad, I do not know whether they were lost together or separately.

The problem stays with the mouse on moving it to a different USB port.

Don't know if it was actually fixed or whether the trigger was an
intermittent physical problem.
