since a few days (probably since the update to 2.6.37-rc), i'm getting
those all the time when using my Bluetooth mouse:

[280835.709269] btusb_bulk_complete: hci0 urb ffff880078654f00 failed to
resubmit (1)

Has this something to do with runtime power management? It seems like it's
always 3 messages about 2 or 3 seconds after the last mouse movement.

And indeed, "echo on > /sys/bus/usb/drivers/btusb/4-2\:1.0/power/control"
makes it go away. However, is this a good idea? And is "auto" for that
feature a good idea if it leads to constant syslog spamming? Or are those
"failed to resubmit" messages mere debug output and thus should not be
logged at all unless some debugging option is chosen?
