Isebenza kancane kancane i-USB-port - indlela yokusheshisa umsebenzi wayo

Sawubona

Namuhla, wonke amakhompyutha anemikhumbi ye-USB. Amadivaysi axhuma ku-USB, kumashumi (uma kungenamakhulu). Futhi uma amanye amadivaysi engafuni isivinini sechweba (i-mouse nekhibhodi, isibonelo), abanye abanye: i-flash drive, i-hard drive yangaphandle, ikhamera - idinga kakhulu ngesivinini. Uma ichweba lizosebenza kancane: ukudlulisa amafayela kusuka ku-PC kuya ku-flash flash drive (isibonelo) futhi ngokuphambene nalokho kuzoba yindlala yangempela ...

Kulesi sihloko ngifuna ukwenza izizathu eziyinhloko zokuthi kungani amabhange e-USB angasebenza kancane, futhi anikeze amathiphu okusheshisa i-USB. Ngakho ...

1) Ukungabi khona kwezingxenyana ze "USB" ezisheshayo

Ekuqaleni kwalesi sihloko Ngifuna ukwenza iphuzu elincane elingezansi ... Iqiniso liwukuthi kunezinhlobo ezintathu zezingxenyeni ze-USB manje: I-USB 1.1, i-USB 2.0 ne-USB 3.0 (i-USB3.0 ibhalwe ngokuluhlaza okwesibhakabhaka, bheka Umfanekiso 1). Isivinini somsebenzi wabo sihlukile!

Umdwebo. 1. I-USB 2.0 (kwesobunxele) kanye ne-USB 3.0 (kwesokudla) amachweba.

Ngakho-ke, uma uxhuma idivaysi (isibonelo, i-USB flash drive) esekela i-USB 3.0 kwisekhompyutha ye-USB 2.0, khona-ke iyosebenza ngesivinini se-port, isb. hhayi ezingeni eliphezulu! Ngezansi kukhona imininingwane ethile yobuchwepheshe.

Imininingwane ye-USB 1.1:

  • izinga eliphezulu lokushintshaniswa - 12 Mbit / s;
  • izinga eliphansi lokushintshaniswa - 1.5 Mbit / s;
  • Ubude obude bekhebula ngezinga eliphezulu lokushintshaniswa - 5 m;
  • Ubude obude bekhebula yezinga lokushintshaniswa eliphansi - 3 m;
  • Inombolo ephezulu yamadivayisi axhumekile ayi-127.

I-USB 2.0

I-USB 2.0 ihluke ku-USB 1.1 kuphela ekuvinjeni okusheshayo nakwezinguquko ezincane ku-protocol yokudlulisa idatha yemodi ye-Hi-Speed ​​(480 Mbit / s). Kunezivinini zedivayisi ye-USB 2.0:

  • Isivinini esincane 10-1500 Kbit / s (esetshenziselwa amadivayisi asebenzisanayo: Amakhibhodi, amagundane, izinjabulo);
  • Isivinini esigcwele 0.5-12 Mbps (amadivayisi alalelwayo / ividiyo);
  • I-ijubane engu-25-480 Mbit / s (amadivayisi wevidiyo, amadivayisi wokugcina).

Izinzuzo ze-USB 3.0:

  • Amandla okudlulisa idatha adlula ku-5 Gbps;
  • Isilawuli sikwazi ukuthola kanye nokuthumela idatha (i-duplex ephelele) kanyekanye, okwandisa ijubane lomsebenzi;
  • I-USB 3.0 inikeza amperage ephakeme, okwenza kube lula ukuxhuma amadivaysi afana nokushayela okunamandla. Ukwandisa amperage kunciphisa isikhathi sokushaja amadivayisi eselula kusuka ku-USB. Kwamanye amacala, okwamanje kungenzeka kube khona ukuxhuma ngisho nabaqaphi;
  • I-USB 3.0 iyahambisana namazinga amadala. Kungenzeka ukuxhuma amadivayisi amadala kumachwebeni amasha. Amadivaysi e-USB 3.0 angaxhunyiwe kwi-port 2.0 ye-USB (uma kwenzeka amandla anele), kodwa ijubane lensiza lizokhawulelwa ngesivinini sechweba.

Indlela yokuthola ukuthi yiziphi izibuko ze-USB ezikhompyutheni yakho?

Ukukhetha okulula ukuthatha imibhalo ye-PC yakho bese ubona imininingwane.

2. Ukhetho lwesibili ukufaka izici. insiza ekunqumeni izici zekhompyutha. Ngincoma i-AIDA (noma i-EVEREST).

I-AIDA

Isikhulu iwebhusayithi: //www.aida64.com/downloads

Ngemuva kokuthi ufake futhi usebenzise isevisi, mane nje uye esigabeni: "Amadivaysi e-USB / amadivaysi" (bheka, umdwebo 2). Lesi sigaba sizobonisa amathrekhi e-USB asekhompyutheni yakho.

Umdwebo. 2. AIDA64 - kwi-PC kunezingxenye ze-USB 3.0 ne-USB 2.0.

2) izilungiselelo ze-BIOS

Iqiniso liwukuthi kuzilungiselelo ze-BIOS isivinini esiphezulu sezindiza ze-USB (isibonelo, isivinini esincane se-USB 2.0 port) angeke sinikwe amandla. Kunconywa ukuthi uhlole lokhu kuqala.

Ngemva kokuvula ikhompyutha (i-laptop), ngokushesha cindezela inkinobho DEL (noma F1, F2) ukungena kuzilungiselelo ze-BIOS. Kuye ngenguqulo yayo, isilungiselelo sejubane se-port singase sibe yizigaba ezihlukene (isibonelo, ku-Figure 3, ukulungiselelwa kwe-USB kusizinda esithuthukisiwe).

Izinkinobho zokufaka i-BIOS yabakhiqizi abahlukene be-PC, ama-laptops:

Umdwebo. Ukusethwa kwe-BIOS.

Sicela uqaphele ukuthi udinga ukusetha inani eliphakeme: kungenzeka ukuthi i-FullSpeed ​​(noma i-Hi-speed, bheka izincazelo kulesi sihloko ngenhla) kukholomu ye-USB Controller Mode.

3) Uma ikhompiyutha ingenayo ama-port 2.0 USB / USB 3.0

Kulesi simo, ungafaka ibhodi ekhethekile ohlelweni lwesistimu - isilawuli se-PCI USB 2.0 (noma i-PCIe USB 2.0 / PCIe i-USB 3.0, njll). Izindleko ezingabizi kakhulu, futhi ijubane lokushintshanisana namadivayisi we-USB landa kakhulu!

Ukufakwa kwabo ohlelweni lwesistimu kulula kakhulu:

  1. qala ukuvala ikhompyutha;
  2. vula isembozo se-unit unit;
  3. xhuma ibhodi ku-slot PCI (ngokuvamile engxenyeni engezansi engakwesokunxele ye-motherboard);
  4. silungise nge-screw;
  5. emva kokuvula i-PC, i-Windows izofaka ngokuzenzekelayo umshayeli futhi ungafika emsebenzini (uma kungenjalo, sebenzisa izinsiza ezikulesi sihloko:

Umdwebo. 4. Isilawuli se-PCI USB 2.0.

4) Uma idivayisi isebenza nge-USB 1.1 isivinini, kodwa ixhunywe ku-port 2.0 ye-USB

Lokhu kwenzeka ngezinye izikhathi, futhi ngokuvamile kulokhu kuvele iphutha lefomu: "Idivayisi ye-USB ingasebenza ngokushesha uma ixhunyiwe kwichwep ephezulu ye-USB 2.0."…

Kwenzeka kanje, ngokuvamile ngenxa yezinkinga zomshayeli. Kulesi simo, ungazama: noma ubuyekeze umshayeli usebenzisa i-specials. Izinsizakusebenza (noma zizisuse (ukuze uhlelo luyibuyisele ngokuzenzakalelayo). Indlela yokwenza ngayo:

  • kufanele uqale ukuya kumphathi wedivayisi (sebenzisa usesho kuphela ku-panel control ye-Windows);
  • qhubeka uthola ithebhu nazo zonke amadivayisi we-USB;
  • ususe konke;
  • bese ubuyekeze ukucushwa kwe-hardware (bheka Umfanekiso wesi-5).

Umdwebo. 5. Buyekeza ukulungiswa kwe-hardware (iMenenja yedivayisi).

PS

Enye iphuzu elibalulekile: lapho ukopisha amafayela amaningi amancane (ngokuphambene nenye enkulu) - isivinini sekhophi sizoba izikhathi ezingu-10-20 ezansi! Lokhu kungenxa yokuseshwa kwefayela ngalinye ngabanye amabhulokhi mahhala ku-disk, ukukhethwa kwabo nokubuyekezwa kwamatafula e-disk (njalonjalo.) Ngalezo zikhathi). Ngakho-ke, uma kunokwenzeka, mhlawumbe iqembu lamafayela amancane, ngaphambi kokukopisha ku-USB flash drive (noma i-hard drive yangaphandle), cindezela efayeleni eyodwa ye-archive (ngenxa yalokhu, isivinini sekhophi sizokwandisa izikhathi eziningi!

Kulokhu nginakho konke, umsebenzi ophumelelayo 🙂
