Dell Optiplex 745 USB Port Problems

We role out Dell Optiplex 745 from a W2K3 server using remote image, running XP Pro SP2.

What we have discovered is, that if 2 devices share a USB channel they don't work until unplugged and plugged back in again.

Even if the K/B & Mouse are on the same channel one or neither will work until reinserted.

We used to have the same problem with HP DC7600 until HP released a MB chipset update!

Sometimes by repeated reinsertion, and using different channels, this seems to 'clear' the issue and everything can then be on the same channel - but there seems to be no logic process to this, just luck!

Any ideas?

Thanks.

We seem to be having a similar issue with Dell 745 machines when using USB recording patch adapters. The sound settings won't hold. (revert back after logging off and on). To date hacking the registry has not helped.

Yes I have just roled out a bunch of optiplex 745 and get the same problem where some of them randomly just hang on boot up. I think ive narrowed it down to being the keyboard so when i hard reboot i just unplug the keyboard and they load up to windows, did you find a solution?

Hi, We haven't had many issues with USB keyboards or mice as yet.
Our main issue has been with the USB telephone adapter we use in our call centre for recording calls.(settings do not hold)
We've had the adapter manufacturer have a look at our setup, they believe the issue is with Dell and the new chipset.
