• also haptic status led pin feature.

Description

Please review, mostly for code organization issues, this is not yet tested, so not yet ready to be merged.
(Will test it an an AVR keyboard next weekend)
Note: in chibios land I used USB_DRIVER macro which points to a global variable.
In order to use a "usbp" pointer I'd have to refactor the code to also store a usbp pointer in the queue.
