Kuthekani ukuba ayisebenzi USB

Inkqubela akemi ngxi, yaye ixesha xa amazibuko yangaphandle kuphela enxuseneyo LPT, eyaziwa ngokuba umshicileli serial - COM, kudala ocande zisabonakala. laptops nje kuphela kunye neekhompyutha kodwa Ezinye izixhobo digital mihla kufuneka siqulathe le Universal Bus serial USB. Eneneni, igama elithi "jikelele" ibhasi ngokufanele: oko ekuqaleni kwimisebenzi yalo yophuhliso ukuba ukudala ivili owawuza ngokumisela i umlawuli encinane isixhobo umntwana ukusebenzisana nayo. Umzekelo, drives kunzima nkqu Pata kunye nemilinganiselo wada wabiliswa uphela ngokusebenzisa iadaptha ekhethekileyo ukusebenza kunye USB ibhasi ngokuchanekileyo, ukuba asingethi, kudane amanye amacandelo ngaphantsi ezithile-. Ukongeza, ngokwenza amandla uphawu abafowunelwa ezibude, ababhekisi bakwazile ukusombulula ingxaki wombane "shushu" kunye qhawulo. Ilinge ukuqhagamshela ifowuni amazibuko amavili ezindala (LPT, COM, PS / 2) kwikhompyutha asebenza kwiimeko ezininzi kukhokelela kwiziphumo kwenkqubo microcontroller.

Universal USB ibhasi iye yaba yimpumelelo kangangokuba ekubeni kuhlaziywe ukuya namhlanje lokuqala sele kudlule iminyaka engaphezu kwama-18, ithuba lokuba ebonakala ezihamba ngemilinganiselo izixhobo zekhompyutha. Ngelishwa, nkqu oku ngamanye amaxesha lutshitshe: ayikasebenzi USB modem, nempuku, khamera. Ngenxa yoko, umsebenzisi ivela njenge "izandla-free" kwaye kwanyanzeleka ukuba bafune isisombululo. Okumangalisayo kukuba, inkoliso USB ayisebenzi kwi laptop, kunokuba ikhompyutha siqu. Abanini amacebo ezinjalo kwimeko efanayo badla khumbula imithetho Murphy kaThixo, awathi ukuba engxakini yenzeke - yenzeka. Enyanisweni, kufuneka sikhumbule ukuba kusoloko kukho isicombululo, kwaye uxilongo "ayisebenzi USB» - kuphela ukuphazamiseka okwexeshana. Okulandelayo sijonga izinto ezibangela le ngxaki nendlela iconjululwe.

Ukukhangela yaba liziko inkonzo ubuchwepheshe bee-computer, ungabona ukuba amaninzi ayisebenzi eziphathwayo USB. Izinga eliphezulu yokuxubana nezombane, ukusetyenziswa esebenzayo kunye nobushushu eliphezulu lwangaphakathi - zezona ngozi engundoqo kwimpilo USB. Le metal isinxibelelanisi emzimbeni lebhokisi isixhobo ezahlukeneyo - yinto nje "isesisiqalo", ukuphunyezwa mechanical zojongano ibhasi lwedijithali. Kuwo imityana ukuya umlawuli USB inika intsebenziswano ibhasi kunye nabanye logic computer. Controller - ezihamba ngogesi (okanye inxalenye yayo). Ngamanye amaxesha ngenxa nokusebenza kakuhle obushushu okupholisa ngaphakathi kwinkqubo incwadi egxile linyuke, ibhodi ayanda kancinci, kwaye ICS ezimbi imilenze soldered ziya disengaged. Isiphumo - akusebenzi USB. Enye isisombululo - iziko lenkonzo.

Nangona ezinye izihlanganisi, zingakotshwa idityaniswe umlawuli enye, nto leyo umisela imiqathango ethile kwi yangoku iyonke. Continuous ukusetyenziswa ngexesha elinye-yezixhobo ezininzi ophezulu-power USB kubangela ukuba umlawuli sokuqhuba iyohluleka, amalahle. Oku kufuneka kuphetshwe. Uhlaziyo omtsha (USB3.0) ixhasa phantse kabini ngoku kwe 2.0 xa uthenga ezintsha ikhompyutha kufuneka ziqwalaselwe.

iikhompyutha Personal nobushushu ingxaki ayikho sibi kangaka. Azisebenzi USB yezinye izizathu. Eyona of them - esisebenza ukutshiswa engeyiyo ezinjengeetheminali uqhagamshelwano phambi kwenkqubo unit le. Kuzo zonke iimeko apho ngaphambi kokuba izihlanganisi USB, abaqhagamshelwe awayezinxibile motherboard iintambo (pigtail) kunye ibhloko ekupheleni. Kwane- ngokwazo ukwandisa block ziquka koko yayo, kwaye xa izixhobo ezidityanisiweyo badla zonakala njengoko isixhobo ngokwalo kunye umlawuli ngaphakathi ikhompyutha. Ukuqokelela ikhompyutha uhlaziywe kwaye ngaphandle ngobungxamo, uyakwazi uzikhusele wena kwezi ezingxingongweni.

USB akakwazi ukusebenza ngenxa ziba yokugaya abafowunelwa kwi isinxibelelanisi. Kuyo nayiphi na iziko nkonzo monakalo ngokukhawuleza ukuphelisa.

Kwaye izizathu ezininzi ezingundoqo

- inkxaso USB ikhubaziwe BIOS yekhompyutha. Ukuze enze oko kungekho sizathu sivakalayo ayikhuthazwa;

- USB plug lwefowuni ayizange ifakwe ngokupheleleyo;

- sohlolo software. Ungazama inkqubo eyahlukileyo yokusebenza.
