Ukuvela e nineties standard USB computer science ongaqhathaniswa revolution ethule: ekugcineni, onjiniyela software kanye hardware, "wamkhumbula" mayelana abavamile abasebenzisi PC Ukusebenzisa ithuba eside elindelwe kumadivayisi "hot" ukuxhuma.
Kwaphela iminyaka eminingi wakhonza zifana ngokwethembeka (LPT), serial (COM) ngisho PS / 2 interface ungavumeli ukuba uqaphele uxhumano ngesivinini kudivayisi exhunyiwe ayisekeli bootstrapping inqubo ukubusa azungeze wenziwa kuphela ngamandla zisuswe. Wozani esikhundleni se-USB okujwayelekile (ibhasi serial) aqede zonke lezi nobubi obuthile. Nokho, njengoba ngezinye izikhathi kunjalo, ngokushesha ngemva ukubukeka inani elikhulu elihambisana amadivayisi, kuwebhu yaqala ukubonakala ku umsebenzisi ecacisa iphutha «-USB kudivayisi ayibonwa". Njengoba sekunama-isondo engaphezu kweyishumi, kodwa inkinga wahlala. Abaningi usabhekene nomlayezo "kudivayisi ayibonwa". Ake sizame ukuqonda okwenzekayo: siyasho izimbangela kungenzeka futhi kwenhlekelele.
Wonke amadivayisi ngoba ibhasi serial zingahlukaniswa zibe wire, okuyinto ukuxhuma kwi-isixhumi port wasebenzisa wire (amaphrinta, ama-scanner amakhamera, amafoni, ama-external hard ngemoto) futhi wireless (induku). Iphutha «-USB kudivayisi ayibonwa" ngokuvamile ehambisana apharathasi yohlobo sokuqala. Kuyinto kanje: ngemva kokuxhuma izintambo futhi amandla supply, ku-Windows izinhlelo eduze umyalezo wephutha iwashi livela. Uma ngalesi sikhathi ukubuka isimo Manager Kudivayisi, bese kubonakala khona njengoba "akwaziwa esiyinhlanganisela USB». Enye yezimbangela ezivame salokhu ukuziphatha - lokukhanda. Noma yimuphi ikhefu babashayeli wire noma ukwephulwa solder ku isixhumi - futhi umyalezo «-USB kudivayisi ayibonwa" akuthathi isikhathi eside. Inkinga esivame kakhulu. Ngaphezu kwalokho, nilalele yokuthi kungenzeka ucingo kungalimala "ngokwalo." Ngokwesibonelo, izolo iphrinta, okungazange kube khona ukuxhumana, ayisekho usebenza namuhla, futhi uhlelo yazisa «-USB kudivayisi ayibonwa." Kufanele ukuxhuma futhi isixhumi ukuba omunye ibhasi isixhumi, futhi uma ehluleka, ukuthatha indawo ngocingo. Ngezinye izikhathi kancane ngobugebengu ngocingo oxhumana nabo isixhumi - umphumela kufana (yingakho sincoma ukuthi ushintshele ku-port ezahlukene). Kodwa kulokhu ejwayelekile amadivayisi ekhona. A kancane nzima uma uxhuma okokuqala.
USB flash oshayelayo, ungayisebenzisi wire, azigomekile amaphutha afanayo. Kulokhu, kufanele uhlole ukusebenza kwe-nezinye isixhumi. Kwezinye izimo, imbangela yenkinga eziwubala - alikho ohlelweni umshayeli. Isixazululo ilula - ukusetha kudivayisi kwesekela luhlelo (ifoni, ikhamera, njll).
Zonke motherboards lwanamuhla kusekela USB 2.0. Ngo-BIOS, ngaleyo ndlela, ungenza izinguquko ekuqhubeni izilungiselelo isilawuli ngokukhetha ukwesekwa izinguqulo 2.0 1.0 (1.1), noma nje version yesibili. Kusobala ukuthi uma kusebenze «USB 2.0 kuphela» idivayisi edlule ejwayelekile ngeke sisebenze kahle. Siyafunda imiyalelo bese uhlola amasethingi afanele.
By the way, embikweni flash drive uma nephutha lokuxhumana kungadalwa ukwehluleka firmware isilawuli. Ngokuvamile wakhuzwa reprogramming.
