I've been unable to get USB working in XP, even after today's update. Being a total Mac user, I'm not overly familiar with the ins and outs of Windows, so I researched a bit today. It appears I have no USB drivers showing up in Windows, anywhere (BIOS or the Hardware settings panel). The set-up: MacBook Pro 2.0GHz, 2GB RAM. Windows was installed from a Win98 OEM disc, then updated using an XP Upgrade disc. Outside of the missing USB drivers (can't see my flash drive or cell phone when connected), XP is running better than on an actual Windows box. Any ideas?
