Vim USB proven lawm yuav nyiam interface yooj yim xwb, ib tug tseem ceeb heev pillar ntawm tus USB 3.0 specification addresses li cas rau SuperSpeed interface yuav tsum nyob twj ywm rau tau tshaj lub lab USB xyuas hauv computer uas twb muaj lawm thiab li yuav hauv cov khw. Rau qhov cov tshuab itand #39; s xov zoo: tag nrho li USB 2.0 yuav ua hauj lwm rau USB 3.0 kho vajtse, thiab USB 3.0 (tsiaj) tas li yuav ua hauj lwm hauv USB 2.0 Radon.
Ua ib feem ntawm lub, USB 3.0 tag nrho ports muaj xws li qhov tsim nyog pins thiab logic rau ntaub ntawv USB 2.0 Pib ntsais koj teeb tseg, thiab tag nrho cov receptacles lawv counterparts ua ntej lawm ntau tshaj. Qhov no txhais tau tias xyuas hauv computer thiab infrastructure yuav tau upgraded los USB 3.0 txhua lub sij hawm, txav lawm yav tom ntej-compatibility tsis muaj compromising rau qhov functionality uas twb muaj lawm.
Mob(nurses), USB 2.0 tag nrho ports yuav tau tshaj USB 3.0 tseg, raws li tag nrho li SuperSpeed yuav tsum muaj peev xwm sawv interfacing hauv lawv pins 2.0 nkaus xwb. Qhov no txhais tau tias ib tug USB 3.0 tsav nyuab (piv txwv) tau xa mus rau ib lub computer USB 2.0 siv 2.0 cable, los yog xa mus rau ib lub computer USB 3.0 siv ib 2.0 cable los yog xa mus rau ib lub computer USB 2.0 Tub ntxhais uas siv ib cable 3.0.
