USB ports are serviceable (display camera as connected and show files) and recognize flash drives as connected but will not show flash drives and their files.

I have tried rebooting and searching automatically to restore a driver for USB Mass Storage Device which is flagged in Device Manager... "Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38) The driver could not be loaded because a previous version of the driver is still in memory." to no avail. I have Googled the works and none of the "fixes" fix.

I almost uninstalled the driver and rebooted but I am scared that the uninstall might knock out all the USB ports. ?

If you have any other USB devices, try those to see if it's specific to just one....

If that doesn't work, see if you can access the memory cache thru the control panel.... or even in a file manager.

BTW... the flash drives work on other PCs.

I often have that problem on my fairly-new computer with both flash drives and SD cards. Sometimes, I have gone to device manager and uninstalled USB, then rebooted and let USB reinstall. That often helps, but it's not a foolproof solution.
I hope somebody has a good 'fix' for this.

Joe... was the driver you uninstalled the USB Mass Storage Device driver? THAT'S what scares me. I have uninstalled individual drivers and rebooted but... ???

Yep, just richt-click and choose "uninstall," then reboot. Yes, it is a bit scary....
But it has never ended in disaster for me...

Just a thought… what way is the USB formatted? Maybe it's not seeing it because of that?

Another thought - have you looked for it using Windows Explorer (the Windows key and E)?

There ends my PC expertise.

Try connecting a drive that works. Leave it connected and then connect the one that won't display to a different port. .

Sorry GNU ... same old questions:

What is your hardware?
HP, DELL, ASUS etc and date of purchase? CPU? Motherboard? BIOS?

What is your opperating system and version?

When was your last succesful access throughout the device...and what did you do afterwards...i.e. update, install etc ....check your log.

For many laptops an F5 during boot will take you to the BIOS.

Transfer the files you want, from a machine that reads it... "to the cloud".

Use a factory NEW device gnu....don't risk the files you want to access.

Malwarebytes wouldn't let me use the auto detection download from Acer soooo, even though the restore point scan said several important programs would be removed (including Malwarebytes), I went ahead with it after creating a new restore point. Purrs like a kitten.

Are sure the flash drive is good? Variations on voltage can destroy them without your being aware of the damage. Test it in another device.

Has the flash drive been anywhere near a Mac?
What I found was that flash drives that had Mac downloads/saves had some funny files starting with a "."
BUT
Flash drives formatted or first used on a Mac were likely totally unreadable on a PC. XP for sure.

Just a thought, not Mac bashing, but Apple do have NIH syndrome. (Not Invented Here since you ask).

Solution, get a Mac evangelist to transfer files using a destination Flash drive that was formatted on a PC. They will tell you it is the PC that is at fault, just smile knowingly.
