27” Mac with Windows 7 Service Pack 1. It is an older Mac for sure.

Worked perfectly with my old USB - A Lexar 128 Jump drive.

When I plug one of the new USB Jump drives, the mouse freezes intermittently and you can see the CPU go crazy in the CPU widget. I can still use it but with the mouse going wonky intermittently, it is difficult. Feel like the USB controller needs to be updated. I know it is an old machine but it is running my business on a small network and whatever I do, I can’t do anything to compromise the machine.

Any help here would be greatly appreciated.
