onpon4 has a fine reply[1] to what type of gamepads/game controller avoid,
which are basically those that only support DirectInput. And what type of
gamepads should work on a Linux kernel without blobs (eg: Linux-libre, Debian
GNU/Linux kernel, etc...) which are basically any standard USB HID. But, I'm
still wondering not for wired USB gamepads, but wireless Bluetooth gamepads.
Does someone has a working wireless gamepad on Trisquel or any other distro
without blobs?
How can I be sure that it will work before buying a wireless gamepad?
And, what would be the procedure to setup the controller if it's Bluetooth?
