Hi all,
Jackd does not start if an USB mouse is plugged into my laptop.
I am using an USB Audio card (Alesis IO|2)
Some infos:
Laptop is a Toshiba Satellite A660
Distribution is Ubuntu Linux 11.04

Could you post
cat /proc/intterupts too? Perhaps your USB interface & mouse are on the
same IRQ.. that might upset things (though it shouldn't)
Have you tried other physical USB ports for the mouse & interface?

The mouse is using too much bandwidth.
Linux jaco 2.6.38-8-lowlatency-pae
This kernel has a buggy USB scheduler that makes any amount of bandwidth
too much. This is fixed in 3.1.5.

Try to connect the devices to ports that belong to different controllers.

Definitely! USB mice are evil, they don't get along well with faster USB
devices.
Also check which audio device JACK sees where. On mine, the order in
which audio devices appear on QJackCtl's list changes frequently. So one
time the USB sound card would be device hw:1, next time it would be
device hw:3. (Also, for some reason, if I have my USB=MIDI interface
plugged in on startup, JACK will try to use it as a sound card.)
There's various ways to name ALSA devices and have JACK connect to them
using their names, that fixes the floating device assignment problem.

And I used one of those to fix the issue on my laptop. Just was
mentioning it for the original poster, in case that was what was
preventing JACK from starting.
