I have a three year old Dell Inspiron 14R.
The Flash Drive is a simple Sandisk Ultra USB 3.0.
When I plug it in, it constantly disconnects and reconnects, sometimes more than two or three times a second.
When it does manage to remain connected for more than a few seconds, as soon as a start a file transfer it will disconnect immediately.
Also there is a popup saying "(G:\) There is a problem with this drive. Scan the drive now and find it."
If I click scan, immediate disconnect and failure to scan.
I have three USBSS ports on my laptop, all with the same problem (with this USB drive).
It works flawlessly on my Xbox, another laptop, and at multiple computers at work, but it has never worked on this one. Other USB devices and flash drives work perfectly.
What I've tried:
Power Options>Change Plan Settings>Change Advanced power settings>USB settings>USB selective suspend
I disabled both options. This worked for many people with this problem.
BIOS Disable Legacy USB
This didn't help.
Disable the USB controllers in the Device Panel.
Also didn't help.
Updated all my drivers for motherboard, USB, etc.
What else can I try?
