[fpc-pascal] USB Human Interface Devices

[James Richters]

Yes, in device manager I see it listed as "HID-compliant vendor-defined device"  also Zadig identifies it as "USB Input Device" and it shows Driver: HidUsb (v10.1.17763.1)

Is there a way to use the windows system HID interface with FPC already in place as there is for other windows APIs?

Hello,

hid.dll is the windows system HID interface, the API provided by Windows.

No, I just look for the product and try to find its drivers, no one name the HID interface. Do you see the device in windows device manager under the HID section "Human Interface Devices (HID)" ?
