I-USB Implementers Forum (USB-IF) namuhla imemezele ukwethulwa kohlobo lwe- Ukuqinisekiswa kohlobo C lwe-USB, umthetho olandelwayo wesoftware ozosebenza njengomugqa wokuvikela ukuvikela amadivayisi ahlanganisa ukuxhumeka kwe-USB-C ezintanjeni ezingahlangabezani nezinga lokuphepha futhi ezingakwazi ukulimaza amadivayisi ashiwo.
Ngale ncazelo womabili amakhompyutha namanye amadivayisi anezimbobo ze-USB-C azokwazi qinisekisa ubuqiniso bedivayisi ye-USB noma ishaja ye-USB enezinto ezifana nesimo sesitifiketi nokuqinisekiswa kwamandla kagesi asetshenzisiwe, kanye nokuqinisekisa ukuthi ayikho isoftware enobungozi ekhona futhi ekwazi ukuthelela ikhompyutha eyisingathile.
Ngokusebenzisa le protocol, amasistimu wokusingatha angaqinisekisa ubuqiniso bedivayisi ye-USB noma ishaja ye-USB, kufaka phakathi izinto ezifana ne- isimo semikhiqizo (incazelo, amandla kanye nezitifiketi). Konke lokhu kwenzeka khona manje lapho kwenziwa ukuxhumana ngezintambo - ngaphambi kokuthi kudluliswe amandla noma idatha engafanele.
Lokhu kuqinisekisa kuvumela amakhompyutha ukuthi azivikele kumashaja e-USB awahlangabezani nezinga futhi ngaleyo ndlela anciphise ubungozi bokuhluleka kwehardware noma isoftware enobungozi efakwe kumadivayisi we-USB azama ukuxhaphaza ukuxhumana kwe-USB
Lokhu kuchazwa kuza ngemuva kokuthi ezinye izintambo ze-USB-C zikwazi ukulimaza amadivayisi kagesi. Uma sikhumbula, unjiniyela weGoogle uBenson Leung, okuvela kuye sikhuluma kokunye okuthunyelweUhlale amasonto ehlola izintambo ze-USB-C amasonto athengiswe yi-Amazon ngemuva kokuthi ikhebula lomuntu wesithathu alithengile likwazi ukudiliza i-Chromebook Pixel yakhe.
Umsebenzi kaLeung uholele i-Amazon ukuthi ivimbele abathengisi abavela eceleni ekunikezeni izintambo ze-USB-C lokho musa ukuhambisana nemininingwane ejwayelekile ekhishwe yi-USB-IF, futhi iphinde yazuza ukuthi imibandela inqunyelwe ngaphakathi kwezinga elethwe namhlanje.
Izici ezibaluleke kakhulu zalesi sitifiketi esikhishiwe yilezi:
- Iphrothokholi ejwayelekile yokufakazela ubuqiniso besitifiketi se-USB Type-C kumashaja, amadivayisi, amakhebuli, nokunikezwa kwamandla
- Ukusekelwa kokufakazela ubuqiniso nganoma iyiphi ibhasi ledatha le-USB noma iziteshi zokuxhumana zokulethwa kwamandla kwe-USB
- Thembela ekuphepheni okungu-128-bit kuzo zonke izindlela ze-cryptographic
- Lokhu kuchazwa kwezindlela ze-cryptographic kumele kwamukelwe emhlabeni jikelele ngefomethi yesitifiketi esikhona, isiginesha yedijithali, i-hash kanye nokwenziwa kwenombolo okungahleliwe.
IMacBook Retina eyi-intshi engu-12 isivele inezinyathelo zokuphepha ezakhelwe ngaphakathi zokukuvikela ezintanjeni ezingathobeli, kepha isici esisha sokufakazela ubuqiniso se-USB Type-C sizonikeza ngolunye uhlaka lokuvikela i-Apple okufanele ilusebenzise. Imishini yamanje yamukela kuphela ama-adaptha kagesi we-USB-C wesithathu uma ethobela ngokucaciswa kwe-USB Power Delivery, futhi uma kutholakala i-voltage eningi, amachweba e-USB-C akuMacBook ayavalwa.
