Too much logging from USB
 

When I go to a text mode console, I get a continuous stream of messages
drivers/usb/input/hid-core.c: ctrl urb status -32 received
and this makes all the consoles unusable. (Terminal windows in X are ok.)

The same message is also the only thing I can get if I use `dmesg` after booting.

This may have come from installing nut (a UPS monitoring package).

What can I do to get this logging under control?

Have you compiled your own kernel? On the 2.6 kernels (maybe 2.4, haven't used it in a couple years) there is an option for 'usb verbose debug messages' under "Device Drivers --> USB". That would be my first (and only) guess.

Most likely the fix for this is to edit the syslog config file (/etc/syslog.conf) and look for a section that logs to /dev/console or /dev/xconsole and comment that out.
