I have a legacy device that works fine on USB 1.0 or USB 2.0 ports.
However it does not work properly on a USB 3.0 port.
I've tried it on a PC with both USB 2.0 port and USB 3.0 port (it works fine on the 2.0 port on that machine but not on the 3.0 port).
The device installs fine on both, e.g. windows will detect it.
The company who manufactured the device have went out of business so I can't get any updated driver or changes made to the programme.
When I connect it to the USB 3.0 it gives timeout errors.
What I'm guessing is happening is it communicates with the device and waits some time then checks for responses, but maybe because the port is faster the response is coming back before it has even checked for a response and then dies.
I'm wondering is there anyway to slow down my usb 3.0 port or put it in some usb 1 compatibility mode so I can use this device.

I had an issue with a simple card swipe for a POS system(usb 1.0). I upgraded to a dell AIO Win10 with 4 3.0 ports, card reader would not work in any of the ports, so I'm thinking 1.0 is works with 2.0 and 2.0 work with 3.0, SO I bought a Manhatten 4 port usb 2.0 hub. Plugged it in, win 10 found it, plugged the card swipe into the usb 20. hub, win 10 found it. Now the card reader works fine.
