Dotaz: USB2.0 na Prestigio 1590W

[Lubos Kopecky]

Mam notebook Prestigio 1590W a koupil jsem si externi disk. Dle vyrobce by USB melo byt verze 2.0, ale presto mi jej to detekuje pouze jako 1.1.

Po bootu systemu se natahne modul jen uhci_hcd, rucni donahrani modulu ehci_hcd nic neprovede, koren se hlasi stale jako UHCI.

Ma nekdo nejakou zkusenost s tim? Podarilo se to nekomu nejak pod Linuxem rozchodit v plne rychlosti nebo to USB opravdu neni verze 2.0?

predem dik

Mam ten isty NB a ten isty problem. Pod Win XP to tiez beha max 1MB/s. V linuxe som skusal rucne nahadzovat vsetky mozne moduly a ovladace a bez uspechu.

Oznacenie USB 2.0 je v poriadku aj ked svinarna.

Oftentimes, marketing gets out ahead of the technology, or at least obscures the technical issues. In the case of the USB 2.0 standard, only Hi-Speed USB 2.0 devices run at 480 Mbps. USB 2.0 Full-Speed/USB Full Speed devices are actually 12 Mbps USB 1.1 products.

T.j. na oznacenie niecoho ako USB 2.0 staci, aby to zvladalo aspon jednu rychlost, ktoru predpisuje standart USB 2.0 a nie vsetky ako je obvykle pri vsetkych ostatnych standartoch. Obavam sa, ze tento kram je USB 2.0 Full-Speed a nie Hi-speed.

Aaaaaaha, tak to dik za ne moc potesive info. Alespon vim, ze se s tim nemusim vic trapit...

Ten notebook ma chipset Intel 915GM - a ten urcite USB 2.0 podporuje! Co ukazuje lspci?

Verze USB je 2.0, ale rychlost odpovida verzi "full", tedy 12Mb/s.

[R]

Chyba tam v tom vypise ten 2.0 radic. Vyzera to tak, ako keby bol vypnuty (v BIOSe?) alebo ho jadro z nejako dovodu nevidelo.

[Lubos Kopecky]

Do BIOSu jsem uz koukal a tam zadny nastaveni neni tykajici se USB :(

Zda se, ze ho nevidi v plne rychlosti jen jadro Linuxu, ale i Windows - XP i Vista, tak mi to taky rika, ze mohu pripojit zarizeni rychleji, ale na vyber zadne rychlejsi porty nenabizi...

[R]

To falosne oznacenie "USB 2.0" (Full Speed) sa moze vyskytovat mozno tak na nejakom cinskom smejdovom USB zariadeni. Rozhodne tak nemoze byt oznaceny port na PC. Chipsety podporuju bud USB 1.1 alebo 2.0. A ICH6M podporuje urcite USB 2.0.

[Semo]

Napr. tu http://www.cdr.cz/a/15559 sa tiez udava USB 2.0. Tie texty asi budu odpisane zo stranok, ktore to vtedy predavaly. Sam si tiez dobre pamatam USB 2.0 a navyse som si vyhrabal oficialne papaiere k tomuto NB a je tam USB 2.0.

Jedine, kde sa hovori o USB 2.0 je mys. Inak je vsade "capabilities: usb-1.10".

[Lubos Kopecky]

Na webu Prestigia je v archivu vydanych notebooku taky uvedeno USB2.0.

Ted jsem se ptal kamose, kterej ma 159W, co je predchudce 1590W, no a jemu se data kopirovaly v klidku 8MB/s, co si pamatuje.
