Postup zprovoznění pod Linuxem

Je dodáván i USB prodlužovacím kabelem, takže zasunout a připojit (například u mě je to /dev/sda1) "mount /dev/sda1 -t vfat /mnt/neco". Je třeba mít natažené jaderné moduly pro SCSI a usb-storage; jádro 2.4.x. Před vytažením odmountit ;-)

Bezny USB flash disk, nezaznamenal jsem problem.
modul: usb-storage
mount /dev/sda1 /mnt/removable

mount -t vfat /dev/sda1 /mnt

Poznámka

Upozornění - existuje i Seitec USB Bar, který podporuje USB 2.0 a velmi špatně chodí (= vůbec nechodí) bez podpory USB 2.0 v jádře (mnohé distrubuce ji tam zatím (8/2003) nemají).

Pokud Vám tedy Váš USB Bar nechodí, zkuste pátrat tímto směrem.

Testovano s MDK 9.1, kernel 2.4.21-0.26mdk. USB port v PC byl jen verze 1.1.
