i have a problem on my other laptop(this is other than my own laptop about which my other thread's i have post and so i dont want the problem of this post to be related to my previous post's) that is pendrive is not detected. when i see in the device manager on the USB mass storage device, there is ! sign which indicates it's having a problem. and then double clicking on it, there is written that :- A driver (service) for this device has been disabled. An alternate driver may be providing this functionality. (Code 32) but the driver USBSTOR.SYS is there on my laptop. other than this sometimes, pendrive is detected but most of times it's not detected.
