Dotaz: problem s pripojenim USB flash disku

[sine.nomine]

kdyz pripojim USB flashku, tak se na chvilku vytvori zarizeni v /dev, ale pak se neco pokazi a udev je zase smaze... distribuce: aurox 11, jadro vanilla 2.6.16, potrebne ovladace mam zkompilovane (navic to nejelo ani s dist. jadrem). USB disk na jinych pocitacich (taky aurox 11, jeden s dist. jadrem, druhy s jadrem 2.6.11) funguje bez problemu...

ruční připojení nepomůže? Pod rootem mount -t vfat /dev/sda1 /media/neco
Někdy se zařízení hlásí jako /dev/sda (bez jedničky). Pokud to funguje, lze nastavit připojování pod uživatelem v /etc/fstab.

Neco podobného se mi stalo taky. Stacilo disk preformátovat pod linuxem a od té doby funguje jak má. Ale ty hlásky s tím kabelem se mi tam neobjevovaly.

pripojit nemam co - udev /zarizeni /dev/sda a /dev/sda1 zase smaze...

formatovat tu flashku pod linuxem se mi moc nechce - nepouzivam to jen na linuxu... a opet: formatovat neni co, udev za sebou uklidi, kdyz se mu nepodari flashku prikonektit.

je to starsi PC a USB je na PCI karte... nemuze byt pes zakopany tam? protoze aurox 11 s dist. jadrem na 2 pc nema s tou flashkou potize a jen na tom jednom ano.
