Is the PNP string for all 3 exactly the same?

Subject: [NTSysADM] "Good" Thumbdrive not Recognized

This may be way OT, but I'm mystified and I'm more likely to get a good answer 
here than anywhere else....

I have three identical thumb drives (PNY UltraFit). All three have Windows 10 
To Go installed on them and I've used them for months on my laptop, until 
lately.....

Suddenly only 2 of the 3 thumb drives are recognized by the laptop. If I boot 
into the OS on the fixed drive these 2 will not show as USB devices at all, let 
alone as disks. I also can no longer boot off of them, so it's the laptop not 
Windows. Again, one of the 3 is still recognized and bootable.

That may not seem so odd except that all 3 thumb drives are recognized and 
bootable on the two other machines that I have tried.

I just can't make sense of this. So far I've updated the BIOS on the laptop and 
after showing hidden devices in Device Manager, deleted all instances of them. 
Not surprisingly this made no difference.

Can anyone explain this?
