Pfupiso yeKuchinja muUSB Interfaces

Pakati pazvo, USB4 standard yazvino (yakadai seUSB4 Cable, USBC4 To USB C) parizvino inotsigira chete mainterfaces eType-C. Panguva iyi, USB4 inoenderana nemainterfaces/protocol akawanda anosanganisira Thunderbolt 3 (40Gbps Data), USB, Display Port, uye PCIe. Mashandiro ayo ekutsigira 5A 100W USB C Cable power supply uye USB C 10Gbps (kana USB 3.1 Gen 2) data transmission ndiyo hwaro hwekukurumbira kukuru.

Pfupiso yeType-A/Type-B, Mini-A/Mini-B, uye Micro-A/Micro-B

1) Hunhu hweMagetsi hweType-A neType-B
Pinout inosanganisira VBUS (5V), D-, D+, uye GND. Nekuda kwekushandiswa kwe differential signal transmission, dhizaini yekubata ye USB 3.0 A Male ne USB 3.1 Type A inonyanya kukosha pakubatanidza simba (VBUS/GND yakareba), ichiteverwa nedata lines (D-/D+ ipfupi).
2) Hunhu hweMagetsi hweMini-A/Mini-B neMicro-A/Micro-B
Mini USB neMicro USB (senge USB3.1 Micro B TO A) zvine ma contact mashanu: VCC (5V), D-, D+, ID, uye GND. Zvichienzaniswa neUSB 2.0, pane imwe ID line inowedzerwa kutsigira mashandiro eUSB OTG.
3) USB OTG Interface (Inogona kushanda seHOST kana DEVICE)
USB yakakamurwa kuita HOST (host) uye DEVICE (kana slave). Mimwe midziyo ingangoda kushanda seHOST dzimwe nguva uye seDEVICE dzimwe nguva. Kuva nema USB ports maviri kunogona kuita izvi, asi kutambisa mari. Kana USB port imwe chete ichigona kushanda seHOST neDEVICE, zvingave zviri nyore. Saka, USB OTG yakagadzirwa.
Zvino mubvunzo unomuka ndewekuti: USB OTG interface inoziva sei kana ichifanira kushanda seHOST kana DEVICE? Mutsetse wekuona ID unoshandiswa pakushanda kweOTG (danho repamusoro kana rakaderera remutsetse weID rinoratidza kana USB port iri kushanda muHOST kana DEVICE mode).
ID = 1: Chishandiso cheOTG chinoshanda muchimiro chevaranda.
ID = 0: Chishandiso cheOTG chinoshanda mumodhi yehost.
Kazhinji, ma USB controller akabatanidzwa mumachipisi anotsigira mashandiro eOTG uye anopa USB OTG interface (yakabatana ne USB controller) yeMini USB kana Micro USB nedzimwe interfaces dzine ID line yekuiswa nekushandiswa.

Kana paine Mini USB interface imwe chete (kana Micro USB interface), uye kana uchida kushandisa OTG host mode, saka uchada OTG cable. Semuenzaniso, OTG cable yeMini USB inoratidzwa pazasi mumufananidzo: Sezvauri kuona, Mini USB OTG cable ine mugumo mumwe se USB A socket uye mumwe mugumo se Mini USB plug. Isa Mini USB plug muMini USB OTG interface yemuchina, uye USB device yakabatana inofanira kubatanidzwa muUSB A socket kune rimwe divi. Semuenzaniso, USB flash drive. USB OTG cable ichadzikisa ID line, saka muchina uzive kuti unofanira kushanda sehost kuti ubatanidze kune external slave device (senge USB flash drive).
