Windows 10: USB Thumb Drive did not mount upon insertion

UP until now, no problem inserting and removing the drive. Then, plugged it in and it did not mount. Other drives failed to mount in same port, but all worked fine in a different port. After a reboot it worked again.


Two questions:

1. What would cause that?
2. Is there something I could have done less drastic than a reboot?

PNY USB Drive won't mount ANY other brand will

A customer that I support recently bought a new Dell Laptop, Latitude, with Win 10/64 1803 currently installed. All drivers per Dell's Support sight and Windows are the most current.

This computer will not mount any drive from PNY whether 2.0 or 3.0 BUT will mount any other brand thumb drive 2.0 or 3.0 that I could locate and try. I tried 4 different PNY USB 2.0 & 3.0 drives and none would mount when plugged directly into the laptop.
I updated Bios, chipset, drivers, any and all USB related drivers but nothing resolved the issue. Reformatted both a 2.0 and 3.0 PNY NTFS and FAT32, this did not resolve the problem.

Beyond the interesting fact that any other brand USB thumb drive I could find (Corsair and Sandisk) would mount. What's more interesting is that the PNY drives would mount on the laptop if it was connected to a dock and the thumb drive plugged into the dock
NOT the laptop. ???

Is Microsoft and/or Dell fighting with PNY??

Any suggestions to attempt to resolve? Anything I missed trying?

 

Location to access USB for opening a inserted thumb drive

See steps how to open and access the contents of your thumb drive:

 

Computer freezing/rebooting when inserting USB devices

That sounds more like an electrical problem. The lockup occurs regardless of which USB port you insert the thumb drive into?
