[DUG] Reading data from a USB

[Wes Edwards]

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.

USB devices generally have unique interfaces and require specific drivers to
access them.  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.

I'm working with a data logger and currently get my data from it through an
RS232 port. 

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