linx 2.4.18mdk a USB mass storage [dlhe]?

[Ernest Beinrohr]

Zdravim, snad mi pomozete. Kupil som si digifotak s podporou USB mass 
storage. Myslel som ze to predsa nemoze byt problem, ale ups. Pripojim 
ho a zapnem, loadnu sa spravne moduly [vypis 1 dmesg je dole], ked vsak 
idem spravit mount tak to robi dve veci. Bud mi zamrzne konzola uz pri 
pisami mount /dev/scsi/host1/bus0/target0/lun0[TAB], alebo sa v tom 
adresari normalne zjavia dva subory _generic_ a _disk_. Ked skusam 
namountovat subor _disk_ dostavam hlasku "No media found" aj ked je to 
block device. Fdisk na tom subore nefunguje [vypis 2]. Ked ho iba 
zapnem, vypisy z .proc su OK [vypis 3]. Pri zamrznuti konzoly dostavam 
[vypis 4].
