The usb3sun makes no beep on connect, but makes the standard beep on disconnect.
this suggests we are getting our tuh_umount_cb (note: not tuh_hid_umount_cb) on disconnect, but not our tuh_hid_mount_cb (note: not tuh_mount_cb) on connect.
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.
this suggests the usb stack may be hitting an assertion failure or one of its device limits.
