Hi,
I have typical problem using usb mass storage device. whenever I connect it into computer usb port , windows XP professional shows unknown device or in device manager it shows yellow question mark. Though all usb port are working fine. There is no problem with usb port. I have checked with all the port but it shows the same problem . Thoush other device like usb printer working fine.
Previously this usb mass storage device was working fine in this computer. I have tested it with other computer and working fine in other computer. I have tried to reinstall/update device driver but no progress. I have tried manually delete the usbstor.sys file from system32 folder and copy/paste another usbsotr.sys file but it fails. checked in system32 folder that usbstor.sys is 25 k(approx) and searching on net I found usbstor.sys is 20 k(approx). whenever i tried to copy/paste this file it automatically become 25 k after pasting. so can't get rid of the problem. whenever i given different path for driver, it shows there is no device driver though usbsotr.sys is there.
Please help to get rid of this problem.
