I have a brand new Dell Precision 380 with a Pentium D 3.0 Ghz processor. My company uses a custom USB 1.0 device. Only on this system, when the device is accessed by our in-house program, the entire system locks up. Tried reinstalling drivers, all the usual suspects, and it just locks up no matter what, and the lockup makes our device act very strangely, constantly restarting. Has anyone else out there had issues with dual core processors or the 380 and older USB devices?
