Kutengesa Kushandiswa kweDhijoni
Vakwegura USB 1.1 madivayiri nematafura, nokuda kwechikamu chikuru, mumuviri unoenderana ne USB 2.0 hardware. Zvisinei, nzira chete yokusvika USB 2.0 kutambisa kutengesa ndeyekuti zviyero zvose uye tambo dziri kushamwaridzana kune imwe sese inotsigira USB 2.0.
Kana, somuenzaniso, une USB 2.0 yedhiyo inoshandiswa ne USB 1.0 cable, iyo 1.0 speed inoshandiswa pasinei nokuti chokwadi ichocho chinotsigira USB 2.0 sezvo iyo cable haibatsiri mutsva, inokurumidza kukurumidza.
USB 2.0 madivayiri nematafura anoshandiswa ne USB 3.0 madivayiri nematafura, vachifunga kuti vari mumuviri unoenderana, achashanda pazasi USB 2.0 speed.
Mune mamwe mazwi, kuwedzerwa kwekufambisa kunowira kune vakuru vehutano hwemhando mbiri. Izvi zvinonzwisisika sezvo iwe usingakwanisi kudhonza USB 3.0 inotama kunze kwe USB cable, uye haugone kuwana USB 2.0 kutambisa kutengesa uchishandisa USB 1.1 cable.
USB On-the-Go (OTG)
USB On-the-Go yakabudiswa muna December 2006, mushure me USB 2.0 asi pamberi pe USB 3.0. USB OTG inobvumira madivayiri kushandura pakati pekuita semuiti uye semuranda kana zvichidiwa kuitira kuti vagone kushamwaridzana kune umwe neumwe zvakananga.
Semuenzaniso, USB 2.0 smartphone kana teretheni inokwanisa kukwevera deta kubva pane flash drive semuiti asi iyo inoshandura kuenda kumuranda iyo iyo yakabatanidzwa kune kombiyuta kuitira kuti ruzivo ruitwe kubva.
Chigadziro chinopa simba (muiti wacho) chinonzi inonzi OTG A-device iyo iyo inopedza simba (muranda) inonzi B-device. Muranda anoita sechigadzirwa chepachigaro mumhando iyi yekugadzirisa.
Kuchinja mabasa kunoshandiswa kuburikidza kushandisa Host Negotiation Protocol (HNP), asi kusarudza pachedu iyo USB 2.0 device inofanirwa kutaridzirwa kuti muranda kana muiti wekusarudzwa ndeye nyore sekusarudza kuguma kweiyo kambo iyo iyo inosangana nayo.
Dzimwe nguva, kuongorora kweHNP kuchaitika nemuiti kuzoona kana muranda wacho achikumbira kuti ave mumiririri, panguva iyo anogona kugadzirisa nzvimbo. USB 3.0 inoshandisa HNP yekuongorora pamwe chete inonzi Rle Swap Protocol (RSP).
