Hi Martyn,

Yes, it should appear as a ‘HID-compliant device’. If that entry does appear, and it’s still not working, it might be worth uninstalling and reinstalling the Crumble software, just to be sure everything’s fine there.

The Crumble software uses the HIDAPI library (written in c) to communicate with the Crumble (https://github.com/signal11/hidapi).

If you build hidtest (on my mac this just pops out when you run make on Makefile-manual), then run it, it should list all the hid devices currently connected. I get this entry when the Crumble is connected.

type: 1c40 05b8
path: USB_1c40_05b8_14200000
Manufacturer: Redfern Electronics Limited

Let me know if you have any questions.

Best wishes,
