Hi, I have a similar question. We are developing an app for Android TV and using a couple different HID devices. One has axis and buttons and works great. The other has only axis and no buttons - and shows up as an HID device with the driver, but not as an input device, so we can't get events. Any thoughts on how to fix this? Do we need some kind of manifest or intent-filter to recognize the device? Thanks!
