Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello to all,
this is my first thread in this forum.
Yesterday my CMM2 arrived and of course I tried it out at once.

I find it is a very good product with very fine workmanship.

After playing arround I detected a small problem concerning one of my keyboards.
In addition to a wired UK keyboard from Packard Bell - which is working very well -
I also own a Logitech K400r wireless keyboard with german layout.
Unfortunately the wireless keyboard is not recognized by CMM2.

Maybe someone has a hint here on how I could make it work?
By the way, yes, I have read the keyboard thread in this forum from a few days ago.

Thanks,
Norbert

The keyboard has a touch panel which almost certainly means it has a built-in USB hub. Unfortunately ST doesn't support USB hubs with their USB framework so nothing that can be done on this until/if they do (in which case I'll also include mouse support).

This restriction is documented in the user manual

Thank you for the fast answer! I see, I have to read the manual.
