One Bank Cheque 㗎陰功，佢哋玩捉字蝨嘅看家本領係講緊 USB 2.0 嘅 Full-Speed Mode，查實都係得 USB 1.1 ＠ 12Mbps 咁低 B：

For all USB 1.1 and 2.0 compatible Full Speed transfers, not Low Speed and not High Speed.

残念です，同佢嘅命運係一樣：

Supports USB 1.1, USB 2.0 Full-Speed

Full = Fool = 12Mbps，真嘅 480Mbps 一定要雞乸咁大隻字話到明係 High-Speed Mode 先得。

堅嘅 480Mbps 真係得幾隻，唔會好多選擇：
