HP v220w 16GB USB

HP Pavilion DV4T-1400 Laptop
Win 7 64

All the other USB I have are working

HP v220w 16GB USB is not working i.e when I plug it the sound is there but its not showing & no error message & no invalid icon in device manager. It works on other HP Laptop Win 7 64 system.

Any info/solution?

See if updating to the latest USB drivers makes a difference.

Hi naren,

Does your HP v220w 16GB USB got an assigned letter under disk drives in device manager? If no give it one; if yes change the letter of the drive.
