Mouse flicker, too manu USB devices?

Hi

I have some peoblems with my mouse suddenly changes position on the screen.
Also my midi-keyboard crashes sometimes, when i'm playing midifiles on my
PC, via a USB midi interface.

My system is:

Dell Inspiron8100, with a Logitech optical mouse on 1 USB port, and a
Logitech USB Hub on the other usb port. On the HUB i have a docking station
for a HP handheld PC, and a USB midi interface. I also have a PCMCIA USB 2.0
interface with a HP 2210 printer connected.

What is it than can cause these mouse movements and midi errors. Too many
devices, driver conflict?

do you have enough power coming into the system? - check what total watts
your PSU is
make sure all drivers are as up to date as poss

Hi

I'm using the original PSU to the HUB, which is at 3.7 A. I can't imagine
that my devices uses more than that :-)
For the Dell i of course also use the original PSU.

Driver should also be up2date.
