請問USB延長線有否分 ver.1 或 ver.2 或 其它野呢?
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~ {:1_255:}
請問應該係咩問題呢?
Thx all~ {:1_347:} 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.{:6_128:} 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.... {:1_256:} 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. ok~
明白哂~
謝謝兩位~ {:1_347:}
