I've successfully used the JvHidDeviceController component (part of the Jedi VCL library) to obtain data from a USB device (in this case a gamepad). There are demos supplied.
You'll need to work out the format of the data obtained, but hopefully self-explanatory or discoverable.

I've got a USB thermometer here which I wrote code to access via a DLL they provide. Unfortunately it's nothing like RS232. You would need to find a device that meets your needs, or just purchase a USB to serial converter. Ross.

Anyone used the USB for retrieving data and if so how ?
