None of my USB2 ports are working on an Intel D865PERL mobo. I've updated the BIOS, updated all drivers available, and still no luck. I've checked intel's support pages and nothing listed other than driver updates. There's a Windows 2000 driver specifically for USB2 on the board, but nothing specific for XP, just one that says it's for USB and AGP - http://tinyurl.com/6gbke
Any thoughts? It's not the end of the world, but with an 80 GB external backup drive, it's taking a LONG time.
