USB device will not connect to VISA or Max

[peter3083]

Hi,

I am trying to control a USB device(DLPC900) from Labview in Windows 11. The device shows up on device manager but not in Max. It is a USB raw device without a manufacturer supplied Driver. How can I get it to show up on max or connect to it with VISA?

Thanks,

Peter

Not.

A "little" more detailed information (but it boils down to "Not" as Quiztus says): https://forums.ni.com/t5/LabVIEW/Ant-USB-with-LabVIEW/m-p/4411816#M1300226

And no, using anything else, be it C, Python or whatever won't get you any further.

That part about "shows up without a manufacturer supplied Driver" means that it is most likely a HID device. Windows claims them by default and doesn't like to let anyone else claim them. It means that the device could be interfaced through calling Windows HID API functions. But!!!! Those HID function are low level C programming and while an experienced programmer could do that through use of the Call Library Node without necessarily crashing the system, it still doesn't help without the exact binary bitmap specification of the message content in the HID bit stream.
