Yog vim li cas USB-ports nres ua hauj lwm?

Muaj ntau computer tswv tseem nco ntsoov lub hnub thaum tag nrho cov lub peripheral pab kiag li lawm kev cob cog rua rau lub system unit ntawm lub serial (COM) thiab thaum uas tig mus (LPT) ports. Cov kev cai nyob haum yooj yim mus siv, uas cov feem ntau tej yam zoo rau tus nqi ntawm motherboards thiab lwm cov khoom uas siv cov interfaces. Lawv disadvantage yog lub cev tsis cuag peripheral pab kiag li lawm "rau tus yoov", tsis muaj tig tawm lub hwj huam mov system unit, raws li zoo raws li ib tug me me bandwidth. Txawm li cas los, nws yog ib yam ntawm cov kev them nyiaj rau "cheapness" thiab ua ntej lub era ntawm multimedia tsis muaj leej twg nyob rau hauv no xyov mloog yog tsis them nyiaj. Nrog rau cov pib ntawm active loj hlob ntawm multimedia yees (Digitisation thiab kis tau tus mob ntawm lub suab, duab) yuav tsum tau mus cuam tshuam rau cov COM thiab LPT hloov. Cov tshwm sim ntawm ib tug ob peb loj tuam txhab uas muag yog tus rov tshwm sim nyob rau hauv 1996, thawj version ntawm lub USB interface (Universal Serial Bus), uas yuav tsum tau scaled raws li ceev thiab txhawb kub-swappable Plug & ua si. Txij thaum ntawd los, ob peb tiam ntawm tus txheej txheem, thiab yog tam sim no khwb khuav txhawb version 3.0. Sadly, txawm tag nrho cov zog ntawm developers thiab versatility tseem muaj ntau cov tswv ntawm lub computer systems tej zaum daim ntawv ceeb toom hais tias cov USB-ports nres ua hauj lwm. Thiab rau tsis muaj khees vim li cas. Yuav ua li cas yog nthuav: lub USB-chaw nres nkoj ntawm tus dais no yog heev yooj yim: nyob rau hauv lub plug tam sim no tsuas 4 nyob ntawm tej (tej zaum 5, lub thib tsib - lub screen), ob tug uas cov ntaub ntawv yog kis tau, thiab tshuav ob yog rau cov fais fab mov.

Kho los yog txij nkawm

Sawv daws yeej paub hais tias nyob rau hauv thiaj li yuav xyuas kom meej du lag luam los ntawm hluav taws xob khoom siv yuav tsum tau tseg audited. Lub tshuab ntxhua khaub ncaws yuav tsum tau ntxuav, nrog rau cov TV cua sob yuav tsum cheb hmoov av, thiab cov xov tooj txawb - mus thauj khoom thiab huv si tsis tseem ceeb cov kev pab cuam. Tab sis lub computer yog feem ntau ib tug "tshaj plaws nyob rau hauv nws tus kheej": nws nyob rau hauv lub rooj tom qab kev txhim kho cov system unit nquag nog nyom lub taw, ntxuav lub dab tsis tsim, thiab hais tias nyob rau hauv lub kiv cua bearings yuav tsum tau tsawg puav ntxiv roj nyob rau hauv Feem ntau, ob peb tau hnov. Yog nws muaj zem hais tias muaj los ib lub sij hawm thaum mam li nco dheev kaw USB-ports? Qhov zoo ces, 90% ntawm cov neeg tsis tau rov qab rau lawv tus kheej, tsis tas yuav mus rau lub Service Center thiab yam tsis tau xav cov nqi.

Ib tug yooj yim input thiab output system

Yog hais tias tej swb nyob rau hauv lub Universal Serial Bus yog tsim nyog los xyuas lub chaw nyob rau hauv lub motherboard configuration kev pab cuam. Nws yog tam sim no nyob rau hauv ob qho tib si portable thiab nyob ruaj ruaj computers: ua kev soj ntsuam tseem ceeb blocks thiab cov thawj zaug chaw hom, xws li lub peev xwm los thaiv USB. Qhov kev pab no yog hu ua tus BIOS (Basic tswv yim / tso zis System). Nyob rau hauv niaj hnub systems, nws twb hloov los ntawm ib tug UEFI, tab sis qhov yooj yim hauv paus ntsiab lus ntawm cov lag luam yog fwm. Nws yog pom tseeb tias txhua txhua computer tswv cia li tau paub yuav ua li cas los pab kom USB-ports rau lub motherboard BIOS. Txwv tsis pub, ib tug me glitch los yog ib tug prank - thiab muaj mus rau lub chaw muab kev pab, tiam sis txhua yam yeej kho tau los ntawm koj tus kheej nyob rau hauv cia li ib feeb.

Configuring lub Rooj Tswjhwm Saib

Yuav kom tau txais mus rau hauv lub BIOS, koj yuav tsum tam sim ntawd tom qab xa rau lub system unit mus nias rau qhov rho tawm khawm ntau lub sij hawm. Nyob rau laptops, qhov no muaj nuj nqi tej zaum yuav raug muab tso rau cov F2, uas yog qhia nyob rau hauv kev tshuaj ntsuam nrog lub logo (los ntawm nias mas, koj yuav tau nyeem cov inscription).

Tu siab, sib tham txog yuav ua li cas los pab kom USB-ports nyob rau hauv lub BIOS, peb yuav tsis piav qhia txog lub caij nyoog ib theem zuj zus ntawm kev ua, vim hais tias, nyob ntawm seb qhov kev siv ntawm qhov kev pab cuam configuration, kev tso kawm ntawm cov khoom yuav sib txawv. Tus neeg siv yuav tsum "taug kev" thoob plaws tag nrho cov ceg ntawm cov ntawv qhia zaub mov, tab tom nrhiav rau lub USB-kev tswj ntawm lub xws li, los yog coj cov lus qhia nyob rau hauv phau ntawv-board thiab siv nws mus txuas rau qhov khoom. Yog li ntawd, yog tias koj USB-ports tsis mus ua hauj lwm, nyob rau ib co boards yuav tsum qhib lub Advanced BIOS nta thiab nrhiav tau cov USB chaw. Yog txhaj rau Sau ib txoj hlua, koj yuav xaiv tau ib lub xeev Enabled / xiam oob qhab los yog rau / tawm. Siv yuav tsum tau tso cai. Nyob rau hauv lwm yam motherboards yuav tsum tau tuaj mus rau lub point ntawm Integrated peripherals thiab nrhiav OnChip lub USB maub software. Raws li txoj cai - Enabled. Nws no kuj pab tau kom paub tseeb tias Legacy USB them nyiaj yug yog tseem muab kev koom tes. Yog li ntawd yuav tsum qhia rau lub BIOS sam Tus neeg siv ua hauj lwm yog txo mus rau qhov ua kom ntawm Universal Serial Bus Controllers.

Registry ntawm lub operating system

Lub qhov rais tso cai rau koj mus programmatically lov tes taw rau kev siv ntawm ports los hloov ib tug xov tooj nyob rau hauv qhov chaw. Txawm li cas los, qhov no ua hauj lwm tsuas yog rau cov neeg pab kiag li lawm uas tau kev cob cog rua rau lub computer, thiab lawv tau ntsia tau rau hauv tus neeg tsav tsheb USB-ports. Lov tes taw / txhob xauv lub ua tau zoo log yuav tsum:

- tseem ceeb ua ke Yeej (cim "qhov rais" khawm) + R;

- nyob rau hauv lub pab, hom regedit (ua);

- mus los ntawm cov ceg mus rau lub HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ USBSTOR;

- nrhiav tau cov Start kab thiab los ntawm ob-txhaj nas hloov tau tus nqi mus rau 4 los ntawm 3. Qhov no yog lub cev kev khiav hauj lwm hom. Hloov cov trio ntawm plaub, on qhov tsis tooj, nws yuav ban siv USB.

Cov kev hloov yuav ua khees tom qab ib tug restart. Peb tsis pom zoo yam tsis tau muaj "kev ua si" nrog rau cov khoom, li no yuav ua rau muaj teeb meem nrog tus nas thiab keyboard yog kev cob cog rua rau qhov kev tsim nyog txuas.

Kev twb kev txuas ntawm USB-ports rau tus kheej computers

Rau yooj yim ntawm kev system unit connectors feem tso tawm nyob rau hauv pem hauv ntej vaj huam sib luag ntawm cov vaj tse nyob. Nyob rau hauv kev, qhov no socket rau cov lus qhia / microphone thiab USB. Xwb, nws yog heev yooj yim thaum txuas rau qhov tsim nyog peripheral yog tsis mus nrhiav ib tug dawb plug nyob rau hauv lub rov qab sab ntawm lub system unit, thiab siv npaj meej muaj nyob nyob. Nyob rau tib lub sij hawm, qhov no yuav ua raws li muaj cov drawback uas lub kev twb kev txuas ntawm USB-ports pem hauv ntej vaj huam sib luag yog ua siv ib tug cable ncav us txog nyob rau hauv lub cev mus rau ntsis pins rau lub motherboard. Li no qhov teeb meem. USB cable yuav tsum tau ua tsis yog los ntawm penny conductors tshaj txoj kev txhaum pheej yig Suav keeb kwm vaj tse, thiab tag nrho ua raws li cov uas yuav tsum tau ntawm cov kuj nqi, qhov zoo ntawm lub soldering / crimping, ntev thiab li ntawd. Connectors tib los ntawm cov rov qab sab ncaj qha soldered mus rau lub rooj tsavxwm thiab raws li ib tug yuav tau txais ntau txhim khu kev qha .

Yog li ntawd, yog tias nyob rau hauv vaj huam sib luag ntawm lub system unit USB-ports ntawm tus kheej computers nres ua hauj lwm, ces koj yuav tsum tshem tawm lub vaj tse cover, nyob rau lub USB board nrog ib zuag txuas voj (kos npe), maj mam muab disengaging lub pins thiab connector thiab re-txuas. Tej zaum zoo heev yooj yim reconnection mus rau lub nyob sib ze zuag. Piv txwv li, thaum taug kev txoj kev mus rau lub USB 5-6, ces nws yuav tsum tau kev cob cog rua rau 7-8.

Incidentally, qhov teeb meem nrog rau pem hauv ntej vaj huam sib luag los ua ke yog ib yam ntawm cov feem ntau. Yog hais tias muaj yog tsis muaj lub sij hawm qhib lub qhov enclosure, lub periphery yuav kev cob cog rua rau lub jacks rau lub rear vaj huam sib luag.

"Noj hmo yog tau txais kev pab", los yog hwj chim teeb meem

Txawm hais tias specification rau universal serial chaw tos tsheb loj teev uas lub siab tshaj plaws tam sim no ib qhov chaw nres nkoj yog 500 MA rau lub thib ob version thiab 900 MA rau peb, nws tsis txhais hais tias tag nrho cov connectors yuav ib txhij txuas pab kiag li lawm nrog noj, thiab txhua yam yuav ua hauj lwm. Ntxiv mus - qhov no yog qhov shortest txoj kev mus rau lub teeb meem thiab cov lus nug ntawm "vim li cas USB-ports nres ua hauj lwm." Tag nrho cov niaj hnub niam muaj ib tug kos xws li Universal Bus, uas, tsuas muab tso rau, yam uas tag nrho cov connectors. Lub cev, qhov no siv hluav taws xob muaj ib tug ncaj qha kev nco nkag nrog cov hoob interrupt thiab muaj peev xwm ntawm cov dawb lub CPU los ntawm niaj hnub khiav hauj lwm ntawm tus me nyuam cov ntaub ntawv ntws. Thaum ib tug loj tus naj npawb ntawm xws ports yuav ua tau ib tug me ntsis. Qhov ntau pab kiag li lawm kev cob cog rua rau lub ceg, lub siab dua qhov tam sim no load ntawm lub maub los. Thiab tom qab ncav ib tug tej yam muaj nuj nqis pib banal tsis muaj hwj chim, uas yog manifested nyob rau hauv failures, failures ntawm kev cob cog rua kiag li lawm thiab txawm tso zis xws tsis ua hauj lwm vim overloading.

Los ntawm txoj kev, USB cable, yuav rau pennies rau lub lag luam, nrog rau cov kev pab uas koj yuav pub ntxiv tshaj ib co "haib" ntaus ntawv yuav muaj ib tug tseem ceeb hauv kuj, uas worsens cov zaub mov qhov teeb meem no. Cov kev cob cog rua peripheral tivthaiv tej zaum yuav tsuas yog tsis ua hauj lwm kom zoo vim voltage losses nyob rau hauv lub conductors ntawm cov neeg pluag filament.

Yog li, yog hais tias, piv txwv li, lub USB-chaw nres nkoj ntawm lub tshuab luam ntawv tsis ua hauj lwm, ces koj yuav tsum kom paub tseeb tias koj yuav siv qhov tsim nyog kev sib txuas lus zoo hlau thiab nyob rau tom ntej mus rau lub connector rau lub Rooj Tswjhwm Saib yog tsis cob cog rua lwm yam ntaus ntawv. Yog li ntawd, yuav luag yeej yuav muaj teeb meem vim hais tias ntawm lub hwj chim, yog tias ib tug qhov chaw nres nkoj yog enabled tshuab luam ntawv nyob rau hauv lub nyob sib ze - lwm DVD (tsis muaj nws tus kheej thaiv), zoo, thiab lub thib peb "ua hauj lwm» Wi-Fi transmitter, los yog tias yeej phem hard drive.

Yuav ua li cas kov yeej cov kev txwv nyob rau hauv tam sim no load

"Ua" xws rau kis tau los ntawm nws tus kheej ib tug tam sim no zoo tshaj qhov ntawd rau cov uas nws yog tsim los, nws yog tsis yooj yim sua. Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm failures nyob rau hauv lub peripheral USB-pab kiag li lawm yuav mus ib tug xov tooj ntawm txoj kev:

- smash lub Cheebtsam rau ib tug ntau yam ntawm controllers, uas yog, lub tshuab luam ntawv yog kev cob cog rua rau lwm davhlau ya nyob twg, uas yog nyob ib sab mus rau lub tso tseg;

- Koom nrog cov feem ntau "voracious" ntaus ntawv mus rau USB 3.0 ports;

- siv ib tug sab nraud hub nrog ib tug active lub hwj chim. Qhov no ntaus ntawv yog ib qho analog ntawm lub tee mus rau lub mains (kab ceg). Nws txuas rau ib tug muaj USB chaw nres nkoj computer, lub hwj chim yog txhab khoom mus rau nws los ntawm nws tus kheej lub hwj chim, thiab tus so ntawm lub peripherals muaj nyob rau hauv lub ports rau lub hub. Heev yooj yim tov. Lub disadvantage yog tias muaj yuav tsum yog ib tug dawb socket thiab cov nyiaj ntxiv rau cov purchase.

Tsav - yog tsis yog ib tug nplua nuj ...

Tam sim no ib tug ntau ntawm cov ntawv teev lus nyob rau hauv kev ua lag luam, uas, nyob rau hauv tas li ntawd mus USB 2.0, muaj yog ib tug tshiab qauv - 3.0. Ntxiv mus, txawm hais tias qee versions ntawm rov qab compatibility, nws tsis yog tag nrho siv. USB-ports kev kho yog xws li hais tias mus ua hauj lwm koj xav tau rau nruab tus neeg tsav tsheb nyob rau hauv lub operating system. Pob sum. Qhov no yog ib tug yuav tsum yuav tsum tau. Yog li, yog hais tias tus tswv ntawm lub computer txuas mus rau lub USB 2.0 ntaus ntawv qhov chaw nres nkoj connector ntawm peb version, tab sis tsis nco qab rau nruab ib lub pob ntawm cov kev pab cuam rau kev pab txhawb nqa, lub lag luam yog tsis muaj guarantee.

Teeb meem nrog rau cov neeg

Hauv plug lub USB tsheb npav muaj plaub caij nplooj ntoos hlav-loaded tooj liab tab. Nws yog ua tsaug rau lawv hais tias muaj yog kev sib cuag nrog lub pawm no ntau npau rau hauv lub connectors. Nrog nquag siv hu yog lawm thiab pib ua hauj lwm. Yuav kom daws tau qhov teeb meem no koj yuav tsum nrog kev pab los ntawm ib rab koob arc dabtsi yog khoov rov qab lub tabs, los yog hloov lub interface cable yog tshiab.

Ntxuav ntawm lub sab hauv thiab sab nraum lub system unit

Heev feem ntau, lub computer zoo superficially huv si, tab sis rau tag nrho cov hmoov av deposits muaj nyob hauv lub cev. Paug ntawm raug connectors thiab ports. Plua plav hauv tsev yog tsis qhia. Yog li ntawd, yog tias ib tug USB chaw nres nkoj tsis ua hauj lwm, koj yuav tsum kom huv si ntxuav lub connector, tshuab plua tshauv nrog ib tug syringe. Nws yuav tsum tau nco ntsoov tias sab hauv thiab sab nraud huv - yog ob yam sib txawv. System unit yuav tsum tau periodic koos tu thiab purging.
