這個月初有日本人買了SSD想在PS4上用,
結果發現PS4只抓到USB2.0,告知非USB3.0裝置無法使用。

感到納悶去查網路資訊,包含索尼官網給出的回覆竟然是
請你USB插快一點
詳閱官網錯誤代碼CE-41902-6(台灣官網好像沒有這個頁面)
https://www.playstation.com/ja-jp/support/hardware/ps4-external-hdd-support/
於是引起推特討論,USB3.0快快插跟慢慢插原來還有差喔?
然後上了新聞

有人去問專家,證實的確是有差

雖然USB3.0 Type-A 和USB2.0是有考慮到相容性的設計。
https://image.itmedia.co.jp/nl/articles/2105/12/kutsu_210512usb02.jpg
但是USB3.0 Type-A的相容設計是在插頭深處去做4pin跟5pin的判斷,
快快插的話,電腦馬上就抓到5pin,作為USB3.0設備開始執行。
https://image.itmedia.co.jp/nl/articles/2105/12/kutsu_210512usb03.jpg
若插太慢,可能還沒插到5pin的地方電腦就抓到設備,就先判斷成USB2.0開始執行了。
https://image.itmedia.co.jp/nl/articles/2105/12/kutsu_210512usb04.jpg
這時就會發生USB3.0設備,但實際上卻是以USB2.0標準執行的現象。
此問題不僅限PS4或PS5,所有的電腦設備都有這種狀況
之前PS板的這篇問題,有可能也是插太慢所造成的誤判。

想確保USB3.0 Type-A都能以該有的速度執行的話,以後記得不要猶豫,
插快點。

我在日本,ISP因為IPv4不夠用去買海外閒置IP,然後我用的IP就是原本在挪威的IP。
但PTT的IP對照SERVER資料太舊,沒更新到這IP已納在日本底下,所以繼續顯示挪威。
