Subject: 2.2.18pre, usb mouse messages

Hi,

I use an USB mouse, it works perfectly both with 'gpm' and with X-window but
time to time, I've this kind of message stream :

[[email protected]] ~ # usb-uhci.c: interrupt, status 3, frame# 20
usb-uhci.c: interrupt, status 3, frame# 44
usb-uhci.c: interrupt, status 3, frame# 68
usb-uhci.c: interrupt, status 3, frame# 92
usb-uhci.c: interrupt, status 3, frame# 116
usb-uhci.c: interrupt, status 3, frame# 140
usb-uhci.c: interrupt, status 3, frame# 164
usb-uhci.c: interrupt, status 3, frame# 188
usb-uhci.c: interrupt, status 3, frame# 212
hub.c: already running port 2 disabled by hub (EMI?), re-enabling...

This message appears with most (all ?) of the 2.2.18pre releases, the actual
one is 2.2.18pre23.

Computer is pentium 200MMX, 64Mb SDRAM.

The messages are harmless debug messages. Anyone want to whip up a
patch to turn them off (like was recently done for 2.4.0-test)? If no
one else does, I can do it later this weekend...
