適当に変換して突っ込んでやればキーボードとかつながるよね、と
コネクタの代わりにするつもりでたくさん買ってきたんだけど、とりあえず直接繋いでみると

見たいになって、どうやらこいつが認識するプロトコルでは通信しない、と跳ねられている用だ。
適当にソースを変更すれば何かしらつながるだろう。
cloverconのソースはGPLで公開されてるので誰でもいじれます。
ちなみに、純正ではこうなる
[ 3936.126814] input: Nintendo Clovercon - controller1 as /devices/platform/twi.1/i2c-1/1-0052/input/input8
[ 3936.144365] Clovercon info: opened controller 1, controller in OK state
[ 3936.159912] Clovercon info: probed controller 1
[ 3936.169405] Clovercon info: added device for controller 1
直接コンソール触れるキーボードがつながれば便利なんだけどなぁ
というか、多分I2Cキーボード、マウスを繋げば（≒作れば）普通に色々動くだろ。
追記：
純正のコントローラから帰ってくるcontroller infoは
[ 16.167399] Controller info data: 01 00 a4 20 03 01
動かない二つは下
[ 40.508637] Controller info data: 00 00 a4 20 00 00
[ 62.145529] Controller info data: 00 00 a4 20 01 01
この４バイト目を３にしてくれ、って上位から投げてるんだけど、下位がいやじゃ、って言ってるっぽいのかな。
