USB 3.0 pqi flash drive suddenly stopped working on USB 2.0 ports

I have a 32GB USB 3.0 pqi flash drive and it used to work on USB 2.0 ports just fine. I don't know why but it suddenly decided to stop working on USB 2.0 ports (still works on USB 3.0).

USB 3.0 port is not faulty.
USB 2.0 port is not faulty.

How do I get it to work with USB 2.0 again?

I would copy the data off and store it someplace if possible. I would take USB 2.0 not working as a warning something may be breaking down in the drive. It might only effect USB 2.0 but it's difficult to be sure.

I'm not a hardware guy so I'm not sure if you can test them with a multi-meter.
