Dotaz: Thinkpad T42 a pomalé usb

[Zbyněk Rektořík]

při připojení flash_disku se stále dokola odpojuje a připojuje. Pomůže až rmmod ehci_hcd (čímž shodím USB 2.0) ale pak jede jen velmi pomalu.Neřešil tento problém u tohoto notebooku už někdy - hledal jsem ale nic jsem nenašel.

Zkuste zapojit ten flash disk do jiného USB portu a pokud připojujete přes kabel, tak buď připojit flash disk přímo nebo jiným kabelem. Máte i modul pro UHCI? Podle lspci máte EHCI i UHCI řadiče, tak by mohl být problém s tím, že je jádro zkouší ovládat UHCI řadič EHCI ovladačem...

S radou T41 a casti T42 byly problemy s motherboardem. Resil jsem stejny problem s tim ze se to u me t41 casem zhorsovalo az prestaly USB porty chodit zcela. Pomohla vymena motherboardu. Zda jeste mate T42 v zaruce, ci mate na neho koupeny nejaky extendent maintanance doporucil bych se obratit na autorizovany servis IBM. (Pokud mate moznost jeste vyzkousete tyto porty v jinem operacnim systemu, aby jste mel jistotu).

Jinak toto je zda se ciste HW problem a prosim adminy o uzamceni tohoto threadu.
