Subject: Repeated USB disconnect and reconnect with Wacom Intuos3 6x11 tablet
Date: Tue, 13 Dec 2005 19:46:00 +0100 [thread overview]
Message-ID: <20051213184600.GA4283@nostromo.dyndns.info> (raw)
Hello,
I just want to report a strange observation that I've made while trying to
setup my Wacom Intuos3 6x11 tablet:
When I use the tablet (e.g. press a button, move the pen) and do not have
any process reading the provided data (e.g. there's no process reading
/dev/input/mouse0 and there's no process reading /dev/input/event5 in my
setup) the tablet disconnects from and immediately reconnects to the USB.
There's one pair of disconnect and reconnect each time I press a button or
use the pen. These disconnects and reconnects disappear as soon as there's
a process reading either /dev/input/mouse0 or /dev/input/event5 (mouse0 and
event5 according to my setup).
I'm able to reproduce this with 2.6.15-rc5, 2.6.15-rc4, and 2.6.14.3,
but haven't tried other kernels yet.
This is what's in the logs (from 2.6.15-rc5):
