dell Inspiron 5555 (7 months old.)
My laptop stopped recognizing several flash drives in any USB port. I can plug either flash drive into a different computer and it works fine. Also, my wireless mouse transmitter will work in other ports on the laptop.
I plug in a flashdrive and go to device manager, USB controllers, and find a yellow triangle beside "mass storage device". I unplug this and the mass storage device disappears.
In the mass storage device properties, it reads under device status: "Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory-Code 38). This is the same for several different flash drives in any port.
If someone has instructions on how to correct this, I would be thankful for help on this problem
