On Buster I could connect 6 PS3 controllers via Bluetooth using sixad (I read it can support 7). In Bullseye and Bookworm I could only connect 4 (and Bookworm has freezing issues with PS3 controllers). I even installed sixad on Bullseye but it didn't change the 4 controller limit. Anyone know if this is a hard cap with the Linux kernels after Buster? Or is there a possible workaround for this to use for Steam Link?
