Tirohanga Whānui mō ngā Huringa o ngā Atanga USB

I roto i ēnei, ko te paerewa USB4 hou (pēnei i te Taura USB4, USBC4 ki te USB C) e tautoko ana i ngā atanga Momo-C anake. I taua wā, ka hototahi te USB4 ki ngā atanga/tikanga maha tae atu ki te Thunderbolt 3 (Raraunga 40Gbps), te USB, te Tauranga Whakaatu, me te PCIe. Ko ōna āhuatanga o te tautoko i te tuku hiko Taura USB C 5A 100W me te tuku raraunga USB C 10Gbps (USB 3.1 Gen 2 rānei) e whakatakoto ana i te turanga mō te rongonuitanga nui.

He Tirohanga Whānui mō te Momo-A/Momo-B, te Momo-A/Momo-B, me te Momo-A/Momo-B Iti

1) Ngā Āhuatanga Hiko o te Momo-A me te Momo-B
Kei roto i te putanga matihiko te VBUS (5V), te D-, te D+, me te GND. Nā te whakamahinga o te tuku tohu rerekē, ko te hoahoa whakapā o te USB 3.0 A Tāne me te USB 3.1 Momo A e whakatairanga ana i te hononga hiko (he roa ake te VBUS/GND), ā, muri iho ko ngā raina raraunga (he poto ake te D-/D+).
2) Ngā Āhuatanga Hiko o te Mini-A/Mini-B me te Micro-A/Micro-B
E rima ngā hononga o te Mini USB me te Micro USB (pērā i te USB3.1 Micro B TO A): VCC (5V), D-, D+, ID, me te GND. Ki te whakatauritea ki te USB 2.0, kua tāpirihia he aho ID anō hei tautoko i te mahi USB OTG.
3) Atanga USB OTG (Ka taea te mahi hei KAIWHAKAHAERE, hei PŪRERE rānei)
Kua wehea te USB ki te WHARE MANA (kaimanaaki) me te PŪRERE (he pononga rānei). Tērā pea me mahi ētahi pūrere hei WHARE MANA i ētahi wā, ā, hei PŪRERE i ētahi wā. Mā te rua o ngā tauranga USB ka taea tēnei, engari he moumou rauemi. Mēnā ka taea e te tauranga USB kotahi te mahi hei WHARE MANA me te PŪRERE, he nui ake te watea. Nō reira, i whakawhanakehia ai te USB OTG.
Ko te pātai tēnei: ​​Me pēhea te mōhio o te atanga USB OTG mēnā me mahi hei HOST, hei PŪRERE rānei? Ka whakamahia te raina kimi ID mō te mahi OTG (ko te taumata teitei, iti rānei o te raina ID e tohu ana mēnā kei te mahi te tauranga USB i te aratau HOST, i te aratau PŪRERE rānei).
ID = 1: Kei te mahi te pūrere OTG i te aratau pononga.
ID = 0: Kei te mahi te pūrere OTG i te aratau kaihautū.
Ko te tikanga, ko ngā pūmana USB kua whakauruhia ki roto i ngā maramara ka tautoko i te mahi OTG, ā, ka whakarato i tētahi atanga USB OTG (e hono ana ki te pūmana USB) mō te Mini USB, te Micro USB rānei me ētahi atu atanga me tētahi raina ID hei whakauru me te whakamahi.

Mena kotahi anake te atanga Mini USB (atanga Micro USB rānei), ā, ki te hiahia koe ki te whakamahi i te aratau manaaki OTG, me whai taura OTG koe. Hei tauira, ko te taura OTG mō te Mini USB kei raro nei i te pikitia: E kite ana koe, ko te pito kotahi o te taura Mini USB OTG hei hononga USB A, ko tetahi pito hei mono Mini USB. Whakauruhia te mono Mini USB ki roto i te atanga Mini USB OTG o te mīhini, ā, me mono te pūrere USB hono ki te hononga USB A i tera pito. Hei tauira, he puku kohiko USB. Ka whakahekehia e te taura USB OTG te raina ID, kia mōhio ai te mīhini me mahi hei manaaki hei hono atu ki te pūrere pononga o waho (pērā i te puku kohiko USB).
