I have a Fujitsu 20Gb USB disk
that I want to use under linux.
I read and followed any documentation that came to my hands:
compiling an appropiate kernel, ..., and _almost_
all seems to be correct. Now I fail to figure out
which device-file (files under /dev/) stands for the disk
so I can't make
mount /dev/??????? /mnt/mydisk
I've looked for such device in many places,
some listed below, with no luck.
I show you the details of my system:
- Linux from Debian 2.2r2 distribution (potato)
with 2.2.18pre21 kernel
- Kernel configuration (have I missed something?) =============
Linux Kernel v2.2.18pre21 Configuration
(options not shown are not compiled in-kernel
nor compiled as module)
SCSI SUPPORT
<*> SCSI support
<*> SCSI disk support
<*> SCSI generic support
[*] Probe all LUNs on each SCSI device
[*] Verbose SCSI error reporting (kernel size +=12K)
USB SUPPORT
<*> Support for USB
[*] USB verbose debug messages
<*> UHCI (Intel PIIX4, VIA, ...) support
<M> OHCI (Compaq, iMacs, OPTi, SiS, ALi, ...) support
<*> USB Mass Storage support (EXPERIMENTAL)

Well (if you reached this line you deserve a prize)
the question is:
- is my USB hard disk supported by kernel 2.2.18pre21?
YES:
- where my error is? which /dev/ should I use?
NO:
You need a 2.4 kernel. Then I have
a problem, since debian potato is not prepared
to support a 2.4 kernel (I think!) and I
want to use a Debian distributed kernel.
thank you very very much in advance.
