請問USB延長線有否分 ver.1 或 ver.2 或其它野呢?

我有兩條6尺長USB延長線(A線、B線),兩隻不同品牌既cam仔(A cam、B cam)

A cam用 A線 or B線都冇問題,或兩條線一齊用都得,正常運作~

但 B cam 只能用 A線,一插 B線就話無法識別~

請問應該係咩問題呢?

Thx all~

At present, we are now using two USB standards:

1. USB1.x (Full Speed): 12Mbit/s
2. USB2.0 (Hi Speed): 480Mbit/s

USB2.0(Hi Speed)延長線 can be used with USB1.x devices but NOT vice versa.

Your case may be related to these two standards. Hope it can help.

我兩條線既線身都係冇任何字眼話係咩ver ,所以都唔知點分,買果時都唔知點樣去揀....

而家買多數都係2.0 但可向下兼容

If you buy in Golden Shopping Centre, you should select those with packing and stating USB 2.0 Hi Speed supported. Just HK$1x - $2x each only for 6 to 10 feet.
