hej,

nie wiem co sie dzieje, mam problem z BARDZO POWOLNYM zapisem na pendrive (kingston travelmate 2GB). widze, ze dziala w USB 2.0, bo kopiuje szybko, natomiast nagranie 8 MB zajmuje ponad 20 minut! dodam, ze zapis konczy sie sukcesem, wiec nie chodzi o mechaniczna blokade pendrive'a ,,klodeczka'' (zabezpieczenie przed zapisem). fizycznie urzadzenie tez jest OK, bo na innych systemach dziala (odczyt/zapis) bez problemow.


martwi mnie, dlaczego modul ehci_hcd nie jest uzywany. niby dmesg mi mowi, ze jest to USB 2.0 a jednak....

lsmod :
