Dear USB Users,
I need help from someone who has successfully used
the "Travel Drive" USB Flash Memory Drive from DTK
under Linux. According to the "manual"
it should work with Linux 2.4.X,
it contains a Sonix USB Flash memory controllet,
it has 128Mbyte of NAND Flash memory.
I read a lot of web pages and failed to find relevant
information before finally writing to this list.
Generic success stories with other USB Flash memories
did not help. I actually tried another USB Flash
memory
(Easydisk) and it worked right away. So the problem
seems to be specific to this (class of) hardware.
In essence everything works except for the mount
command:
mount -t vfat /dev/sda1 /mnt/usb
mount: wrong fs type, bad option, bad superblock on
/dev/sda1, or too many mounted file systems
Meanwhile in /var/log/messages the following lines
appear:
Oct 31 17:24:51 hermes kernel: Attached scsi removable
disk sda at scsi1, channel 0, id 0, lun 0
Oct 31 17:24:52 hermes kernel: SCSI device sda: 256000

Oct 31 17:25:32 hermes kernel: FAT: bogus logical

Oct 31 17:25:32 hermes kernel: VFS: Can't find a valid
FAT filesystem on dev 08:02.
Oct 31 17:25:39 hermes kernel: FAT: bogus logical
sector size 54341
...
Does anyone managed to solve a similar problem?
More details:
Under Windows 2000 the device works perfectly.
Under Linux Redhat 7.3 (or even 8.0) it is
recognized, eg. /var/log/messages contains
the following (after it is plugged in):
Oct 31 16:48:16 hermes /etc/hotplug/usb.agent: Setup

I also have reasonably looking values in
/proc/bus/usb/devices:
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2
Spd=12 MxCh= 0
D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64

C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50
Driver=usb-storage
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
The only thing that does not work is mounting the
device.
Any help would be greatly appreciated,
Gabor
