This may be a dupe posting. I tied to send it when I was unsubscribed to stop the flood of digests. Anyway here goes again ---------------------- I have been having trouble with USB ports for weeks and the Keyspan USB PCI card finally crapped out. Neither of the two port would work and were not being recognized by the System Profiler. Before going to CompUSA to purchase a new Belkin, I pulled the Keyspan USB PCI card and cleaned the contacts with a pencil eraser. Installed the card and it lives! For once I managed to fix something rather than screwing it up. It seems to be working good and even picky devices, like the iMic, are now very happy wth the two fresh USB ports. I hope this helps someone experiencing USB weirdness! Dick
