I'm trying to access an HID Device for OCR and Mag Stripe reading, the Desko mini MPR. It's venpid is 0x0744 0x001D and it has three interfaces, [usage page usage id] 0x0001 0x0002, 0x0001 0x0006, and 0xFFA0 0x0001.
Like the linked issue, FindAllAsync returns a DeviceInformation, HidDevice.FromIdAsync returns null, and DeviceAccessInformation.CurrentStatus throws ElementNotFound.
I understand usage page 0x0001 is blocked but I expect 0xFFA0 to get access. What can I do to access this device? Custom UMDF? Brokered Components? Get a new device - how do I know ahead of time it's compatible?
Thank you,
