USB Human Interface Device (HID) in LabVIEW

[nealpederson]

How do you write/read to/from an HID USB device in LabVIEW? Note that this
is not a mouse or keyboard but does use the standard Windows XP HID driver.

That depends. If this device is part of the USB TMC standard, you can do the steps in the following KB.

If not, use VISA to create a USB Raw device driver for it.

Matt,

Neither of the bellow worked. I believe this answer's why:

The device registers as an HID and the above link says that I would have to
change firmware to fix the problem. That's not going to happen because the
hardware is made by another Mfg.

Any other ideas for communication to my USB/HID device? All I need to do is
write and read data from it. The device driver shows an hid.dll. I wonder
if I could call the DLL to accomplish what I need to do. The problem is
that I don't know where to find documentation to setup the DLL call.

If you knew the functions in that hid.dll, you could interface with it directly with LabVIEW using a Call Library Function Node. As far as the functions to do the reads and the writes, you'd need to know what calls they make in that DLL. That may be your best bet with this device.
