How to read data from a USB device in Windows32
(1/1)
Hopestation:
Hi.
I am writing an application which communicates with 2 external devices: a KKSystems USB-485 converter to connect to a Eurotherm controller and a Prologix GPIB-USB converter to connect to a Fluke multimeter.
Both converters contain the same FTDI ic, so I can't identify which converter is attached to which COM port.
I have downloaded Microsoft's USBVIEW utility which shows me that one device is:-:
iProduct: 0x02
0x0409: "Prologix GPIB-USB Controller"
and the other is:-
iProduct: 0x02
0x0409: "USB Serial Converter"
I have looked at libusb, but this appears to be for Linux systems only.
USB.PAS is written by Apple, so I assume the same applies.
Is there a Windows library for accessing USB data?
Can anyone provide an example?

No, it's cross platform.

For windows, the registry is the key is your problem. Each comm port will give you a name that you can follow to your USB device. Use regedit to track the strings you gave above.

Try the SynaSer package from synapse
i think it support USB ports and it's cross platform
