I am working on a Dell Windows Vista Home Premium x64 Laptop that does NOT recognize any USB Flash drives.(They did work until recently.)
Symptoms:
This computer keeps asking me to provide the proper driver for the device. (USB Flash Drive)
It does appear in the device manager with a question mark. "No drivers are installed for this device"
It does NOT appear within Disk Manager.
When I turn on the laptop, the flash drive will light up and blink.
Actions Taken: (NONE OF THESE WORKED)
I tried all 3 USB ports
I have tried multiple flash drives that I know to be good because they work on several other computers without a problem.
Rebooted multiple times with and without a flash drive.
All Windows critical updates and driver updates have been installed.
I updated the BIOS
I updated the Intel Chipset driver (From Dell Website)
I updated the Intel Chipset driver (From Intel Website, (newer))
I have uninstalled and tried to re-install the USB flash drive in device manager.
I have checked disk manager but it doesn't appear. Therefore it cant be a drive letter conflict.
I tried the FixIt for "Hardware and Devices". (This only tells me that I need to install the driver, duh!).
I tried the Microsoft "Cumulative update roll-up for USB core components" but it says it does not apply to this computer.
System restore points do not go back far enough to fix the problem.
I have run SFC /SCANNOW
I have run CHKDSK on C: drive.
I scanned for viruses and mal-ware with multiple scanners. - System is clean.
Computer is out of Warranty.
Anyone else have any other ideas I can try?
I am trying to avoid re-installing the operating system and I need to get this going ASAP.
