[Leica] OT: USB 3 PCI card claims "not migrated," but still works

[Peter Klein]

Summary:  The old Transcend 2-port USB 3 PCIe card in my PC died this 
past week. It worked fine for years. I replaced it with a FebSmart 
2-port card.  The replacement appears to work fine. But Device Manager 
says that it's "not migrated due to to a partial or ambiguous match."  
Should I be worried?

Details:  I just installed a "FebSmart" FS-U2-Pro USB 3.0 PCIe card, $13 
from Amazon.  My computer is a Dell Optiplex 980, 8 GB memory, 450 GB 
SSD system drive, 2000 GB data drive, Windows 10 Professional x64.  The 
Optiplex 980 is not officially compatible with Win10, but many 980 
owners have successfully upgraded.  Mine has been happily running Win10 
since last year.  I use USB 3 to back up my computer, and to download 
files from my camera SD cards.

I keep getting the error "Device not migrated" in the Device Manager 
entries for the Renesas USB 3.0 Host Controller and Hub. Despite the 
error, the USB card appears to work correctly. I can use it with my 
Seagate portable hard drive (for backups), a SDI card reader, and 
various flash drives.  Speeds appear comparable with the old card. A 2GB 
copy of RAW camera files from a card reader to my hard drive, and from 
the hard drive to my backup USB drive all went flawlessly, and bit 
compares of all these files showed no errors.

The FebSmart card was supplied with a driver dated 2011(!).  The 
manufacturer's web site has the exact same driver. Windows loads very 
recent Microsoft drivers (late 2020 and 2021).  I have tried 
uninstalling and reinstalling both drivers, and I get the same result. I 
tried the remedies mentioned in various Web articles.  No help. I 
contacted the manufacturer and got the following reply:

"Hello,I suggest you relaod System,for brand PCs some times it have some 
limitations . Some brand PCs do not accept the device ,it is no way to 
add it on . But if you reload systems all problems will be done."

In other words, "just reinstall Windows and all your software." Ummm, no.

Frankly, I'm not sure that the error message isn't bogus, since the card 
works.  So at this point, I can just run with the current card unless 
something truly goes wrong, or replace it with a $20 Inatek card 
(Chinese company), or a $37 StarTech card (made in Taiwan for a Canadian 
company).  Throwing much more money than that at the problem is probably 
not worth it.  I'll probably replace the PC in a year or two, but I'd 
like to get a bit more life out of it for now.

Any thoughts or suggestions happily considered.  Thanks!
