45Nuyagawaの個人箱にまとめた奴を引っ張ってきてみた

USBの端子の規格。
規格が非常に複雑
端子の形は一つだけなのに、転送方法の規格が多すぎる
どの機器がどの規格に対応しているのかわからない
USB 3.2 Gen 2x2 ってなんだよ45Nuyagawatakker
ついでに1台の機器でも端子ごとに対応する規格が違うことがある。
ノートPCで「この端子はTB3対応だけどこっちはUSB3.2 Gen 1x2 = USB3.0ね」みたいな状況
マジでやめてほしい。良くない。
ついでにケーブルも、パッと見同じ見た目なのに微妙な違いで「別物感」を醸し出してくる
「端子の近くに⚡マークがついてる」とか
やめてほしい45Nuyagawa
せめて端子の色をガラッと変えてくれtakker
でも裏表関係ないしUSB microBみたいに抜けたり弱ったりすることがないから使っちゃう。良くない。45Nuyagawa
microBは使用頻度に対して耐久性がなさすぎた。

20Gbps/レーン × 2レーン=40Gbps
USB4、Thunderbolt 3ベースといいつつTB3の完全上位互換というわけではなく、一部機能がオプション対応である。
カオスの予感。
「USB4」が正式名称らしい45Nuyagawa
しかもスペースを空けないらしい
なんでこれだけ小数点以下ないの……takker

これに、USB Power DeliveryDisplayPort Alternate Modeがついたり、スマートフォン各社が独自の仕様で高速給電を実装したりするので、より一層カオスになる。
XiaomiOPPOなんかの高速充電もそうだけど、「速度はUSB2.0だけど5V/3A流せる!!!」みたいなやつも
それぞれのオプション機能も、物理的に対応できる限界(特に給電周りは顕著)があるので、さらに混沌を極める。

じゃあThunderbolt 4を全装置に実装すれば良いじゃん、となるんだけど、必要以上に速すぎるので
伝送可能距離が短い
頑張っても2mがいいとこ?
処理するチップが高価
ケーブルにもチップを付けなきゃいけなかった気がする
この事情はUSB Power Deliveryと似通ってるな
ケーブルが極太にならざるを得ない
ノイズ対策とか

とかとか……
HDMIみたいに1ポートずつライセンス料取られるみたいなのだったら地獄だな
HDMIひどいなtakker
Display portができたのもそういう弱点があったからなのかなあ
