FlashDrives not Recognized in certain ports ???
I have already followed this article with no success:
Cruzer flash drive NOT detected by Windows PC
The Problem:
We have two identical 16GB USB-3.0 SanDisk Cruzer Glide flash-drives.
The wife's machine, DELL Optiplex 780m tower, Windows 7 Pro, with a 5-port 3.0-USB card AND a 4-port 3.0-USB panel in the floppy-disk opening.
Until now, everything we have plugged into the 4-port front panel has always worked; flash-drives, ext. HDDs, card-readers, all have always worked in this front panel.
However, the front panel does not acknowledge the presence of either of the new 3.0 SanDisk flash-drives; no device-inserted/removed noise, nothing.
The LED lights do light up though.
I can plug these into any of the front or rear 2.0 ports and they instantly show up; likewise the five 3.0 ports on the rear (on the card).
When I try them in the front 4-port 3.0 panel, they do not appear in disk management, nor do they show up anywhere in device management; other than the lights working, it is if they did not exist.
I have some 2.0 USB SanDisk flash-drives and they work without fail in the front 3.0 ports.
I have the exact same 3.0-USB set-up on my identical machine and these drives work fine in my front panel.
How can I fix this ?
Thanks for reading.
