I know this has come up many times before, but I think I've performed all the suggested fixes, and still no lluck.
The back four ports work fine with everything. The front two ports I added and wired to headers 5 & 6 work for some things - Olympus camera, palm pilot, so I think it's wired OK. But they don't work for the SanDisk Cruzer mini series. I get various messages, ususally that XP doesn't recognize the new hardware. The Device Manager shows Unknown Device (But does show an Intel 82801EB USB2 Enhanced Controller - 24DD).
The Bios has been updated to v.10149. The Bios is set up properly, and sees the SanDisk USB storage, but Windows doesn't. I've reformatted, installed XP and all updates, installed the latest Intel Chipset Software Installation Utility in that order. I have not mapped any drives. SanDisk does not provide an XP driver, saying that it is on SP-1 (now SP-2), so I can't update the driver. Any suggestions appreciated, and I'll be sure to respond as to results.
