USB no longer recognized
Up until a few weeks ago I could use my USB Stick on this XP Home SP2
computer. Nowadays I canīt, when I plug it in a bubble pops up saying something like "Could not recognize USB device" and in the device manager it shows as "Unknown USB device" A few days ago my niece had her USB stick plugged in (it works) so out of curiousity I plugged in mine. Surprise! it worked!!! I could read my stick and all. Then, she removed her USB Stick and then the "Unrecognized USB device" bubble popped up again. Now I canīt access my USB stick again. Obviously my device is not damaged but there is something wrong with the XP system. Any ideas what this could be? Thx, Emilio |

Are you using the "Safely Remove Hardware" icon in the system tray to
properly remove the device, or are you just yanking it out without stopping it? If you removed the device while shadow copy was in progress (delayed write), then the thumb drive is most likely corrupted and cannot be accessed (as you have found). If another known good device works in the same USB port as the inoperative thumb drive, then you know the fault is not with the port. In the future, with thumb drives, you should *ALWAYS* stop the device using the "safely remove hardware" icon, even if the drive is showing no activity. Honu. "Touch Base" wrote in message ...
