Incamake y'Impinduka muri Interface za USB

Muri zo, USB4 igezweho isanzwe (nka USB4 Cable, USBC4 To USB C) ubu ikoresha gusa ubwoko bwa Type-C. Hagati aho, USB4 ikorana n'uburyo butandukanye bwo guhuza/gukoresha porogaramu harimo Thunderbolt 3 (40Gbps Data), USB, Display Port, na PCIe. Imiterere yayo yo gushyigikira amashanyarazi ya 5A 100W USB C Cable na USB C 10Gbps (cyangwa USB 3.1 Gen 2) ni byo byashinze urufatiro rwo gukurura abantu benshi.

Incamake y'ubwoko bwa A/Ubwoko-B, Mini-A/Mini-B, na Micro-A/Mikro-B

1) Ibiranga amashanyarazi bya Ubwoko bwa A na B
Iyi pinout irimo VBUS (5V), D-, D+, na GND. Bitewe no gukoresha uburyo bwo kohereza ibimenyetso bitandukanye, imiterere y'aho USB 3.0 A Male na USB 3.1 Type A ishyira imbere guhuza ingufu (VBUS/GND ni ndende), hagakurikiraho imirongo y'amakuru (D-/D+ ni ngufi).
2) Ibiranga amashanyarazi bya Mini-A/Mini-B na Micro-A/Mikro-B
Mini USB na Micro USB (nka USB3.1 Micro B TO A) bifite contact eshanu: VCC (5V), D-, D+, ID, na GND. Ugereranyije na USB 2.0, hongeweho indi ID line kugira ngo ishyigikire imikorere ya USB OTG.
3) Interineti ya USB OTG (Ishobora gukora nka HOST cyangwa IGIKORESHO)
USB igabanyijemo HOST (host) na DEVICE (cyangwa slave). Hari ibikoresho bishobora gukenera gukora nka HOST rimwe na rimwe ndetse na DEVICE mu bindi bihe. Kugira imiyoboro ibiri ya USB bishobora kubigeraho, ariko ni ugupfusha ubusa umutungo. Iyo imiyoboro imwe ya USB ishobora gukora nka HOST na DEVICE, byaba byoroshye cyane. Bityo, USB OTG yarakozwe.
Noneho ikibazo kiravuka: Ni gute interineti ya USB OTG imenya niba igomba gukora nka HOST cyangwa DEVICE? Umurongo wo kumenya ID ukoreshwa mu mikorere ya OTG (urwego rwo hejuru cyangwa rwo hasi rw'umurongo w'indangamuntu rugaragaza niba port ya USB ikora muri HOST cyangwa DEVICE mode).
ID = 1: Igikoresho cya OTG gikora mu buryo bwa slave.
ID = 0: Igikoresho cya OTG gikora mu buryo bwa host.
Muri rusange, ibikoresho byo kugenzura USB byinjijwe muri chips bishyigikira imikorere ya OTG kandi bigatanga uburyo bwo guhuza USB OTG (buhujwe na USB controller) kuri Mini USB cyangwa Micro USB n'izindi interfaces zifite umurongo w'indangamuntu ugomba gushyirwamo no gukoreshwa.

Niba hari uburyo bumwe gusa bwo gukoresha Mini USB (cyangwa Micro USB), kandi niba ushaka gukoresha uburyo bwa OTG host, uzakenera insinga ya OTG. Urugero, insinga ya OTG ya Mini USB igaragara hepfo ku ishusho: Nkuko mubibona, insinga ya Mini USB OTG ifite impera imwe nk'isoketi ya USB A n'indi impera nk'isoketi ya Mini USB. Shyiramo Mini USB plug muri Mini USB OTG interface ya mashini, maze igikoresho cya USB gihujwe kigomba gucomekwa muri soketi ya USB A ku rundi ruhande. Urugero, USB flash drive. Insinga ya USB OTG izagabanya umurongo wa ID, bityo mashini izi ko igomba gukora nk'isoketi kugira ngo ihuze n'igikoresho cyo hanze (nk'imodoka ya USB flash).
