Kuthiwani uma akusebenzi usb

Inqubekela akusho yima, esikhathini lapho nezimbobo yangaphandle kuphela kuhambisana LPT, kangcono eyaziwa ngokuthi iphrinta futhi serial - Sekuyisikhathi eside COM, sekudlule la mavangeli. Akukhona nje aphathekayo namakhompyutha kodwa futhi lonke imishini yesimanje digital kufanele siphathe Universal Bus yomkhiqizo-USB. Empeleni, igama elithi "jikelele" ibhasi has kufanele: kuba ekuqaleni ekuthuthukisweni umsebenzi walo wawubheke ukudala isondo ayezosenza ngokubeka isilawuli encane kudivayisi yengane ukuze uxhumane nayo. Ngokwesibonelo, ngisho Pata hard drive, kanye namazinga Sata ngokusebenzisa adaptha akhethekile ukuba asebenze kahle nge ibhasi le-USB, ukusho lutho kwezinye izingxenye ngaphansi eqondene. Ngaphezu kwalokho, ngokwenza amandla isignali oxhumana anobude obungalingani, onjiniyela wakwazi ukuxazulula inkinga "hot" uxhumano kanye Ukukhipha. Umzamo ukuxhuma idivayisi waya emathekwini kungekho masondo amadala ezimoto (LPT, COM, PS / 2) kukhompyutha ezisebenza ezimweni eziningi kuholela okukhiphayo kohlelo microcontroller.

Universal-USB ibhasi uye waphumelela ukuze kusukela wokubuyekeza lokuqala kuze kube namuhla Sekuphele iminyaka engaphezu kuka-18, isikhathi ukuthi kubonakala umxhwele ngezindinganiso imishini computer. Ngeshwa, ngisho lokhu ukuthuthukiswa ngezinye izikhathi ehluleka: kungaphumeleli usb imodemu, nempuku, webcam. Ngenxa yalokho, umsebenzisi ibonakala njengendlela "hands-free 'futhi baphoqwa ukuba ukufuna isixazululo. Ngokumangalisayo, iningi USB kungasebenzi ku laptop, kunokuba ikhompyutha siqu. Abanikazi zinsizakuphila usesimweni esifana ngokuvamile khumbula imithetho Murphy, owawuthi uma enkingeni engenzeka - kwenzeka. Eqinisweni, kumelwe sikhumbule ukuthi kukhona njalo ngekhambi, futhi uphethwe "akusebenzi usb» - kuphela ngokuphazamisa okwesikhashana. Okulandelayo sibheka izimbangela zale nkinga futhi kanjani ukuyixazulula.

Ufuna ibe sesevisi ubuchwepheshe bama-computer, ungase ubone ukuthi avame akusebenzi usb amanothibhuku. Izinga eliphezulu ukuhlanganiswa of zikagesi, wokusetshenziswa okusebenzayo kanye okusezingeni eliphezulu lokushisa yangaphakathi - kukhona usongo olukhulu ukuze impilo USB. Isixhumi metal emzimbeni exhumanisa idivayisi abafanele - kungcono nje "kuwukusika elijikayo", ukuqaliswa mechanical digital ibhasi esibonakalayo. Kusukela ke izintambo ukuya isilawuli USB inikeza ibhasi ukuxhumana nalo lonke logic ikhompyutha. Isilawuli - ezisetshenziswayo ezihamba ngogesi (noma ingxenye yalokho). Ngezinye izikhathi ngenxa ukusebenza kahle lokushisa lwaluyophola ngaphakathi ohlelweni notebook is ngokweqile landa, ibhodi yandisa kancane, kanye ICS ezimbi imilenze soldered kuthiwa disengaged. Umphumela - akusebenzi usb. Omunye isixazululo - sesevisi.

Nakuba abanye nezixhumi, bangakwazi ixhunywe isilawuli olulodwa, okuyinto unemingcele ezithile samanje Imininingwane. Okuqhubekayo yesikhathi esisodwa ukusetshenziswa kwamadivaysi ephezulu amandla USB ambalwa kubangela isilawuli sokuqhuba umthamo esiphezulu, amalahle. Lokhu kufanele kugwenywe. Kubuketwa entsha (USB3.0) isekela cishe kabili esikhona kunokuba 2.0 ezivamile lapho uthenga kwikhompuyutha entsha kumele kubhekwe.

amakhompyutha Siqu okweqile inkinga akuyona acute kangaka. Akasebenzi usb nangenxa yezinye izizathu. The main wabo - isilawuli omlilo of elingalungile uxhumano ezikhumulweni phambi iyunithi uhlelo. Kuzo zonke izimo lapho ngaphambi nezixhumi USB, ezixhunywe amahanisi umbadlana wiring (pigtail) nge block ekupheleni. Engingakusho nemiyalezo ukwandisa block zihlanganisa ephambene lawo, futhi lapho lamadivayisi axhumene zivame zacekela phansi idivayisi uqobo isilawuli ngaphakathi ikhompyutha. Ukuqoqa ikhompyutha ucabangisisa futhi ngaphandle kokucabangisisa, ungazivikela kusukela loko.

USB awukwazi ukusebenza ngenxa ziba ngcono mechanical oxhumana nabo isixhumi. Kunoma sesevisi nomonakalo onjalo ngokushesha ukuqeda.

Futhi izizathu eyisisekelo

- ukusekelwa USB ikhubaziwe BIOS sekhompyutha. Ukuze wenze kanjalo ngaphandle esizwakalayo is hhayi Kunconywa;

- USB ipulaki zedivayisi ingafakiwe ngokugcwele;

- ube nenkinga software. Ungazama uhlelo lokusebenza ezahlukene.
