Zakladam samostatnu temu, ktoru venujem mojim experimentom s rozbehanim USB Host podpory na ZTE Skate.
Tu budem postupne spisovat moje vysledky.

Ako som daleko:
1) Mam uspesne skompilovany kernel 2.6.35.7 s aktivovanou USB Host podporou. Zatial
su problemy s tym, ze dost cuca baterku aj v stand-by mode, pretoze msm_otg nechce uvolnit kernel wakelock
a tym brani telefonu dostat sa do rezimu spanku.

2) Mam USB konektor Mikro <-> Samica, ktory mi dal k dispozicii vlkodlak1, za co mu patri velka vdaka.

3) Potrebujem este USB Hub s externym napajanim, kedze ten co som vyhrabal doma sa mi podarilo odpalit pripojenim nevhodneho zdroja (povodny som nenasiel). Zdochol aj ked vystupne napatie bolo mensie ako pozadovane. Zrejme prilis vysoky prud.

Pokus c.1...

Kedze nemam momentlne ten Hub s externym napajanim, skusil som pichnut flash disk len tak bez napajania, co sa bude diat. Vyzera to dobre, lebo system reaguje uz len na pripojenie USB mikro -> samica.
Avsak ledka flash disku sa nerozsvitila - zrejme chyba ta stava.

Tu je vypis ako jadro reagovalo na pichnutie USB konektora:

Pokracovanie nabuduce

Ok, takze problem s kontaktom by mohla vyriesit ina USB redukcia napr. taka s dlhsim kablikom (origo. je to urcene pre SGS2/Note) a s tym USB Hubom ti nepomozem...lebo mam v pocitaci asi 10 USB tak to nepotrebujem...

Hub sa pokusim zohnat zajtra niekde cestou domov z prace, ak mi zvysi cas.

EDIT: Novy HUB som zohnal. Tak dnes skusim pokracovat v experimente, ak sa podari.

EDIT2:
Tak experiment sa zatial nepodaril. Podozrievam redukciu, vyzera to na slaby kontakt niekde, lebo mi to cvici hore dole, hlavne ked sa dotknem tej redukcie. Je dost volna v kontakte s telefonom. Asi to bude chciet zohnat inu Idealne asi alternativu s predlzovacim kablikom. Hub je OK. Notebook mi ho pekne zaregistroval.

Skus tam tu redukciu nejako zafixovat napr. gmuickami, poloz si ho na stol a vyved z toho USB predlzovacku...dost nestastne riesenie ale za pokus to stoji. Akonahle mi pridu tie alternativne by som ti jednu mohol poslat . Ale skor ako do 2-3 tyzdnov to asi nedojde :/.

Ono skusal som vselico. Aj ked som to pridrzal v zafixovanej polohe, proste to spojenie nejakym zahadnym sposobom odide. A ked s tym zasa trosku pohybem, nachvilu nabehne...

Zdravim CECO, dnes ma nieco napadlo

Nemas nahodou taky kabel ze USB z ktoreho ide microUSB a dalsie USB? Pouziva sa to na pripojenie extreneho HDD/Mechaniky. Aby si to mohlo zobrat viac stavy ked potrebuje.

Ze by si si redukciu pichol do mobilu, do redukcie pichol klasicku USB predlzovackua do toho ten kabel a ten kabel do nabijacky. A tak budes videt kedy to ma stavu(svieti cervena dioda) a v akej polohe to mas zafixovat. Potom uz ti len staci pripojit do tej predlzovacky USB a mozes testovat...

Dost ubohe ale ja tak doma testujem ktora redukcia je dobra

Nemam, bohuzial...
