By mhando kusangana zvakadaro mano zvinogona kutumirwa sechikamu hurongwa pfungwa kana sezvo vakaparadzana nematunhu (chip) sendarama kombiyuta motherboard, uye Mwanasikana Board (kuwedzera kadhi). Maererano PCI kubatana nzira USB-controller inogona configured kuti PCI mabhazi uye PCI Express.

Magadzirirwo uye mhando namano

Two Mhando mano izvi zvakagadzirirwa kuti USB1.1 Specification. Saka USB1.0 Intel kambani yakatanga USB-controller akadai UHCI uye OHCI. The musiyano namano izvi ndizvo chete nzira kuwana evoruzhinji. Muchiitiko chokutanga zvinyorwa zvenhoroondo vari zvayakaita yakarongwa nzvimbo ino zvengarava, basa kwezvavakaisa goho mashoko, uye yechipiri - vari chikamu pachake kombiyuta ndangariro. USB-OHCI controller mhando anoonekwa kuva akangwara kupfuura mhando UHCI. mukana uyu rinobva kukwanisa kwayo kusunungura chikuru processor nokuva kuita purogiramu mabasa chokuita mashoko kuchinjirwa pamusoro USB mabhazi. Both controllers anoshandiswa 32-ikakuruma kugadzirisa.

Nokuti USB2.0 controller yakagadzirwa USB Universal Serial Bus Type EHCI. It anokwanisa kutsigira basa kumhanya (480 Mbit / s). Izvi controller kuburikidza vakaparadzana kwema inotsigira yakaderera-nokukurumidza USB1.1 inowanikwa kutsigira nomumugwagwa kwaitora nguva namano.

Nokuti USB3.0 yakagadzirwa nokukurumidza USB-mhando hondo controller XHCI, rinogona kutsigira kupanana ruzivo zvachose zvitatu aimhanya.

Kuti muchidimbu, ngationei kuti kana kombiyuta yako hauna kuti USB-zvengarava, nemhaka zviduku okunatsiridza zvinokwanisika kuisa USB-controller. Kwakadaro mano vakatakudzwa kubva muchimiro ane kuwedzera kadhi PCI-mhando kana PC-makadhi kuti Laptops. Remote controllers anowanikwa aine USB1.0 rutsigiro 2.0 uye 3.0. Kana vakasarudza vakazvirongedza zano rakadaro, zviri nani kusarudza kupfuura kunokurumidza, sezvo mari yavo rinenge chete. Maererano nenheyo iyi inogona kutsiviwa ane yaivapo controller nokukurumidza. Zvisinei, mazuvaano kwakadaro Musakanganwa kuti unofanira reinstall vatyairi kuti controller kupedza oparesheni.
