USB CHAW NRES NKOJ TAU QEEB - YUAV UA LI CAS KOM NWS CEEV

Send

Nyob zoo.

Niaj hnub no, txhua lub koos pis tawj muaj nrog USB chaw nres nkoj. Cov khoom siv txuas rau USB yog kaum (yog tias tsis ntau pua). Thiab yog tias qee qhov khoom siv tsis xav tau ntawm chaw nres nkoj nrawm (nas thiab keyboard, piv txwv), tom qab ntawd qee qhov lwm tus: flash drive, tsav sab nraud nyuaj, lub koob yees duab - yog qhov xav tau ntawm nrawm. Yog tias qhov chaw nres nkoj khiav qeeb: hloov cov ntaub ntawv los ntawm lub PC mus rau USB flash drive (piv txwv) thiab rov qab ua ke yuav dhau los ua npau suav phem ...

Hauv tsab xov xwm no kuv xav kom nkag siab txog cov laj thawj tseem ceeb vim li cas USB chaw nres nkoj tuaj yeem ua haujlwm qeeb, zoo li muab qee cov lus qhia kom ceev ua haujlwm nrog USB. Yog li ...

1) Tsis muaj qhov "nrawm" USB chaw nres nkoj

Thaum pib ntawm tsab xov xwm Kuv xav ua tus taw me me ... Qhov tseeb yog muaj 3 yam ntawm USB ports: USB 1.1, USB 2.0 thiab USB 3.0 (USB3.0 yog cim xiav, saib Daim Duab 1). Qhov ceev ntawm kev ua haujlwm yog qhov sib txawv!

Daim duab. 1. USB 2.0 (sab laug) thiab USB 3.0 (txoj cai) cov chaw nres nkoj.

Yog li, yog tias koj txuas lub cuab yeej (piv txwv li, USB flash drive) uas txhawb USB 3.0 rau lub khoos phis tawj USB 2.0, ces lawv yuav ua haujlwm ntawm qhov chaw nres nkoj nrawm, i.e. tsis ntau li ntau tau! Hauv qab no yog qee qhov tshwj xeeb cov tshuab.

USB 1.1 Cov Lus Qhia Tshwj Xeeb:

tus nqi sib pauv - 12 Mbps;
tus nqi qis pauv - 1.5 Mbps;
qhov ntev tshaj plaws cable ntev rau kev hloov pauv siab - 5 m;
qhov ntev tshaj plaws cable ntev rau kev sib hloov nqi tsawg - 3 m;
tus naj npawb siab tshaj plaws ntawm cov khoom siv sib txuas yog 127.

USB 2.0

USB 2.0 sib txawv ntawm USB 1.1 tsuas yog hauv kev kub ceev dua thiab me me hloov pauv ntawm cov txheej txheem hloov ntaub ntawv rau hom Hi-speed (480Mbps). Muaj peb lub nrawm rau USB 2.0 li:

Qhov qes-ceev 10-1500 Kbps (siv rau kev sib tham: Cov twj, nas, dhia kom zoo);
Puv ceev 0.5-12 Mbps (audio / video);
Kev siv hluav taws xob ceev 25-480 Mbps (video ntaus ntawv, khoom siv cia).

Cov txiaj ntsig ntawm USB 3.0:

Muaj peev xwm ntawm cov ntaub ntawv sib kis ntawm cov kab nrawm txog 5 Gb / s;
Tus maub los muaj peev xwm ib txhij txais thiab xa cov ntaub ntawv (tag nrho cov qauv hloov), uas tau nce cov haujlwm ceev;
USB 3.0 muab amperage siab dua, uas ua rau nws yooj yim mus cuag cov cuab yeej xws li nyuaj tsav. Qhov ntxiv zog rau amperage txo lub sijhawm them lub sijhawm ntawm cov khoom siv txawb ntawm USB. Hauv qee kis, lub zog tam sim no yuav txaus los txuas txawm tias saib;
USB 3.0 yog sib xws nrog cov qauv qub. Nws muaj peev xwm txuas cov khoom qub rau cov chaw nres nkoj tshiab. USB 3.0 cov khoom siv tuaj yeem txuas mus rau hauv USB 2.0 chaw nres nkoj (nyob rau hauv rooj plaub los ntawm lub hwj huam txaus), tab sis cov cuab yeej ceev yuav raug txwv los ntawm kev ceev ntawm chaw nres nkoj.

Yuav ua li cas kom paub seb qhov chaw nres nkoj USB twg nyob hauv koj lub computer?

1. Qhov kev xaiv yooj yim tshaj plaws yog nqa cov ntaub ntawv mus rau koj lub PC thiab saib cov txheej txheem kev yees.

2. Qhov kev xaiv thib ob yog rau nruab tshwj xeeb. nqi hluav taws xob rau kev txiav txim siab cov yam ntxwv ntawm lub khoos phis tawm. Kuv pom zoo kom AIDA (los yog TXHUA YAM).

Aida

Tub ceev xwm lub vas sab: www.aida64.com/downloads

Tom qab kev teeb tsa thiab khiav cov nqi hluav taws xob, tsuas yog mus rau ntu: "USB Devices / Devices" (saib daim duab 2). Ntu no yuav qhia cov USB ports uas nyob hauv koj lub computer.

Daim duab. 2. AIDA64 - lub PC muaj USB 3.0 thiab USB 2.0 chaw nres nkoj.

2) BIOS nqis

Qhov tseeb yog tias nyob hauv BIOS cov chaw teeb tsa qhov siab tshaj plaws rau USB ports yuav tsis suav nrog (piv txwv li, Qes-nrawm rau USB 2.0 chaw nres nkoj). Nws raug nquahu kom kuaj qhov no ua ntej.

Tom qab tig lub computer (laptop), tam sim ntawd nias lub DEL (lossis F1, F2) khawm kom nkag mus rau BIOS nqis. Ua raws li cov version ntawm nws, qhov chaw nres nkoj nrawm tuaj yeem nyob rau ntau ntu (piv txwv, hauv Daim Duab 3, USB chaw teeb tsa yog nyob rau hauv ntu "Advanced").

Cov nyees khawm rau nkag mus hauv BIOS ntawm cov sib txawv ntawm cov PCs, laptops: //pcpro100.info/kak-voyti-v-bios-klavishi-vhoda/

Daim duab. 3. Kev teeb tsa BIOS.

Thov nco ntsoov tias koj yuav tsum tau teev tus nqi siab tshaj plaws: feem ntau nws yuav yog FullSpeed (lossis Hi-speed, saib cov lus piav qhia hauv tsab xov xwm saum toj no) hauv USB Controller hom kem.

3) Yog tias lub koos pis tawj tsis muaj USB 2.0 / USB 3.0 chaw nres nkoj

Hauv qhov no, koj tuaj yeem nruab ib lub rooj tsav xwm tshwj xeeb hauv chav kaw lus - tus tswj hwm PCI USB 2.0 (lossis PCIe USB 2.0 / PCIe USB 3.0, thiab lwm yam). Lawv raug nqi, tus nqi pheej yig, thiab qhov nrawm thaum sib pauv nrog USB-devices nce ntxiv rau qee lub sijhawm!

Lawv kev teeb tsa nyob rau hauv chav kaw lus yog qhov yooj yim heev:

tua lub computer ua ntej;
qhib lub hau npog ntawm chav system;
txuas lub rooj tsav xwm rau PCI qhov (feem ntau yog nyob rau hauv qis sab laug ntawm cov niam);
kho nws nrog cov ntsia hlau;
tom qab tig lub PC, Lub Windows yuav nruab cov tsav tsheb thiab koj tuaj yeem pib ua haujlwm (yog tias koj tsis pom nws, siv cov kev siv hluav taws xob los ntawm cov ntawv sau no: //pcpro100.info/obnovleniya-drayverov/).

Daim duab. 4. PCI USB 2.0 maub los.

4) Yog tias cov cuab yeej ua haujlwm ntawm USB 1.1 ceev tab sis txuas nrog USB 2.0 chaw nres nkoj

Qhov no qee zaum tshwm sim, thiab feem ntau hauv qhov no ib qho yuam kev ntawm daim ntawv tshwm: "USB lub cuab yeej tuaj yeem ua haujlwm tau sai dua yog tias nws tau txuas rau lub USB siab ceev 2.0 chaw nres nkoj."…

Qhov no tshwm sim, feem ntau vim yog teeb meem nrog tus tsav tsheb. Hauv qhov no, koj tuaj yeem sim: ua qhov hloov kho tus tsav tsheb siv tshwj xeeb. hlauv taws xob (//pcpro100.info/obnovleniya-drayverov/), lossis rho tawm lawv (yog li lub kaw lus yuav rov kho lawv). Yuav ua li cas ua:

ua ntej koj yuav tsum mus rau tus thawj tswj lub cuab yeej (tsuas yog siv qhov kev tshawb pom ntawm lub Windows tswj vaj huam sib luag);
txuas ntxiv nrhiav qhov tab nrog txhua USB khoom siv;
rho tawm tag nrho cov ntawm lawv;
tom qab ntawd hloov kho cov txheej txheem kho vajtse (saib Daim Duab 5).

Daim duab. 5. Hloov kho cov txheej txheem kho vajtse (Device Manager).

Lwm qhov tseem ceeb: thaum luam ntau cov ntaub ntawv me me (zoo ib yam li ib qho loj) - daim ntawv ceev yuav 10-20 zaug qis dua! Qhov no yog vim muaj kev tshawb fawb rau txhua daim ntawv cais cov ntawv dawb ntawm lub disk, lawv cov kev faib tawm thiab kho cov disk tshiab (ntxiv rau lub sijhawm technical). Yog li ntawd, yog tias ua tau, nws raug nquahu kom nyem ib pawg ntawm cov ntawv me me ua ntej kev luam lawv mus rau USB flash drive (lossis sab nraud hard drive) rau hauv ib cov ntaub ntawv khaws cia (ua tsaug rau qhov no, daim ntawv ceev yuav nce ntxiv! Zoo tshaj plaws archivers - //pcpro100.info/vyibor-arhivatora-luchshie- besplatnyie-arhivatoryi /).

Yog txhua yam rau kuv, txoj haujlwm zoo 🙂
