please help , i have a dell laptop. the usb ports some times work and some times dont , i have to continuously insert and remove for the pendrive to show.
Does this happen to all the USB ports? Have you tried to see if other pendrives are having the same issue? Specification of your PC?
How old is your laptop? If it's pretty old, the USB port can be quite loose if you have been inserting and removing many USB devices for years. In such cases, what you can do is get a USB extension cable, or a USB hub and hook it up to any USB port that is still "tight". That way you get to use a new USB port and limit the damage to your notebook's USB ports.
