I've been having problems with my USB ports ever since I installed Service Pack 2 for Windows XP. Somehow it will recognize my iPod and my portable memory device, both of which were installed and recognized before SP2. But now it will not recognize my new camera or my new printer on any of my 6 USB ports. I've tried updating the drivers and also reinstalling the software for all of them but nothing seems to work. If anyone knows the answer to my problems please let me know. Thanks.
