1209:2303 Atreus (Keyboardio version) keyboard with Kaleidoscope

[delan]

The behavior for the Apple keyboard is odd. The usb3sun makes no beep on connect, but makes the standard beep on disconnect. If a different (working) keyboard is attached, it behaves normally. If the Apple keyboard is re-attached, though, the usb3sun seems hung: no connections from any keyboard are recognized, and no beep is emited on disconnecting the Apple keyboard. A reset using the on-board button restores normal function. This keyboard is known to function normally with other non-Apple hardware (it was used to type this report while connected to a Raspberry Pi running Plan 9).

Notably, the Keyboardio Atreus does not exhibit this behavior; the usb3sun beeps on connect/disconnect as for the working keyboards.

this suggests we are getting both our tuh_hid_mount_cb (note: not tuh_mount_cb) on connect, and our tuh_umount_cb (note: not tuh_hid_umount_cb) on disconnect.
