He āhuahira tino hirahira tō te USB : koia te aratau moe ina kāore i te whakamahi i te pūrere. E kiia ana hoki ko "Atawhai Hiko" :
He pono ka whakatārewatia te pahi USB i muri i te 3 ms ki te kore e whakamahia ināianei. I te wā o tēnei aratau, ka pau anake te wae i te 500o.

Whakamutunga, ko te pūwāhi kaha whakamutunga mō USB ko tēnei paerewa e āhei ai tēnei paerewa ki te whakahiko hāngai tonu i te pūrere ki te rorohiko kia kore ai e hiahiatia te onāianei o waho.

Kua tino nui te hanganga USB mō ngā take matua e 2 :

- He hohoro kē atu te tau karaka rangatū USB.
- He iti ake te māeneene o ngā taura rangatū i nga taura whakarara.

He ōrite te hanganga o te wiringa ahakoa te tere o te tarenga. E rua ngā aho ka mauria e te USB :
- Ko te takirua tohu mō te whakawhitinga raraunga D+ USB me D- USB
- He takirua tuarua ka taea te whakamahi mō te putanga hiko GND me te PH.

Kāore te takirua tuatahi i whakahāteangia mō ngā pūrere pōturi pēnei i ngā papapātuhi, kiore rānei e haere ana i te 1.5 Mpps. Ka whakamahi ngā kāmera, ngā uruoro me ētahi atu i ngā waea ārai ārai kia tae ki te 12Pae/s.

Kua hoahoatia te paerewa USB kia taea ai te tūhono i ngā momo pūrere maha.
Kei te Usb 1.0 e rua ngā aratau whakawhitiwhiti :

- 12 Mp/s i roto i te aratau tere-tiketike.
- 1.5 Mp/s kei te tere iti.

Ka kawea mai e te paerewa USB 1.1 ētahi whakamōhiotanga ki ngā kaiwhakanao pūrere engari kāore e huri i te rere.


E tautoko ana te USB i ngā tere e 3 :

- "Tere Iti" i 1.5Mbit/s – (USB 1.1)
- "Tere Katoa" i 12Pōkai/s - (USB 1.1)
- "Terenga Tiketike" i 480Mbit/s – (USB 2.0)

Ko ngā RW katoa e tautoko ana i ngā tere pahi e rua, "Tere Katoa" me te "Tere Iti". I tāpirihia te "Terenga Tiketike" me te āhua o te tauwhāiti USB 2.0.
Heoi anō, kia taea ai te whakamahi i tēnei terenga whakawhiti, me whakarahia e koe ngā papamāmā me ngā pūmana USB e tautoko ana i te USB 2.0.

Me tutuki i te pūnaha kia toru ngā here e tono ai ka taea te whakahaere USB.
1 - me āhei te whakahaere i te hononga me te momotutanga o te pūrere.
2 - Me taea te tauwhitiwhiti ki ngā pūrere hōu katoa kua mono mai me te kimi i te huarahi pai rawa hei whakawhiti i te raraunga.
3 - me puta tētahi tikanga kia taea ai e ngā atekōkiri te whakawhiti kōrero ki te rorohiko me te pūrere USB, e huaina ana hei tataunga.

I te taumata tiketike ake, ka taea hoki e mātou te kī atu me whai atekōkiri tētahi OS whakahaere USB mō ngā pūrere rerekē, e whakarite ana i te hono ki te pūnaha mahi.

Mēnā kāore i te pūnaha te atekōkiri taunoa mō te pūrere kia tāutatia, me homai e te kaiwhakanao pūrere.

- Patohia Tētahi tūhono, tapawhā hanga.
Ko te nuinga o te wā ka whakamahia mō ngā pūrere hōkaiipurangi hahaka (papapātuhi, kiore, kāmera tukutuku).

- Patohia ngā tūhono B, hanga tapawhārite.
Ka whakamahia mō ngā pūrere tere-tiketike pēnei i ngā puku mārō o waho.

Ko te roanga mōrahi e whakaaetia ana e te paerewa ko te 3m mō tētahi taura kāore e herea ana mō tētahi pūrere USB "Hakahaka" (= 1.5Mb/s) me te 5m mō tētahi taura whakangungu kei te pēhi i tētahi pūrere USB Katoa (=12Mb/s).

Kei roto te taura USB i ngā mono rerekē e rua :
Mā te pūwhānui o tētahi mono e kiia nei ko te MOMO USB Ko Tūhono, kua tūhono ki te RW me te momo pārongo B, mōkito B rānei :
I te 2008, i whakamōhiotia e USB 3.0 te aratau tere tiketike ake (SuperSpeed 625 MP/s). Engari whakamahi ai tēnei aratau hōu i te whakawaehere raraunga 8b/10b, nō reira ko te tere whakawhiti tūturu ko te 500 MP/s anake.

Ka tuku te USB 3 i tētahi hiko hiko, e 4.5 paraina.

Kei ngā pūrere hōu ētahi tūhononga ki ngā hoapā 6 kaua te 4, ka whakaūngia te hototahi whakamuri o ngā tuketo me ngā taura ki ngā putanga tōmua.
I tētahi atu wā, kāore e taea te hototahi whakamuri, kāore e hototahi ana ngā taura USB 3.0 Momo B ki ngā turanga USB 1.1/2.05, kei te whakamahia ngā pūurutau pēnei.

I te tōmua o te tau 2010, i whakaurua te USB 3 ki ngā hua kiritaki. E whakaaturia ana nga mau wāhine e ōrite ana ma te tae kikorangi.
Ka puta hoki i ngā turanga wahine USB whero, e tohu ana i tētahi hiko teitei ake e wātea ana, ā, e tika ana mō te whakahiko tere o ngā pūrere iti ahakoa kei te weto te rorohiko.
(māu e tautuhi ki te BIOS, USB EFI rānei)
E ai ki te tuhinga, mā tēnei whakatipuranga hou "e āwhina ki ngā hoahoa tīariari o te USB 3.2 me te USB 2.0 me te tārua i te hōkaiipurangi hei whakaroha i te mahinga USB-C." Nō reira, ka hototahi ētahi o ngā putanga tawhito ake o USB, ā, ka taea kē e Thunderbolt 3 (i runga i te USB-C) te whakaatu tere i te 40 Kkp/s !

Mā USB 4 e whakahohe i te whakahaere hōkaiipurangi hihiri mō ngā pūrere tūhono katoa i runga i tētahi pahi kotahi. Arā, kāore te hōkaiipurangi e whakawehe ōrite i waenga i ngā pūrere tūhono katoa, engari ka tūaritia ki te pūkete i ngā āhuatanga o ia pūrere. Heoi anō, me manawanui te kite i te taenga mai o ēnei tūhono hōu.
He pono, ka whakakitea mai ētahi atu mōhiohio pū ki te hui USB Developers Day panuku i te ngahuru 2019. Mā tēnei e whakarawe te nuinga o ngā pūrere Apple.
