problem with freecom cdrom drive (USB)
Hi Folks,
I recently bought debian 3.0 (pre) from Lehmanns (a German bookstore). I
installed it on my laptop. (Fujitsu - Siemens Lifebook). I already have
Windows 98 installed and I just copied the first CD of the 4 CDs onto a
windows partition. After that I did a regular install using a bootdisk
from that windows partition.
The problem is the cdrom drive is an external one made by freecom connected
to the laptop with a USB Cable also made by freecom. (As far as I know
this cable has its own controller) I wasn't able to get it run with one of
the shipped precompiled kernels, so I compiled a kernel myself 2.4.9-686.
I included scsi support, scsi cdrom support, usb support, uhci support ( I
tested both drivers) usb storage support and freecom usb/atapi bridge
support. Now after inserting the usb cable the cdrom was recognized and
installed under /dev/sr0. Mount worked and I was able to use ls, cd but as
soon as I read one of the files -- For examples Packages.gz -- The message
freecom reset called appears. The cdrom drive still runs (it's rather
noisy) but doesn't transmit any more (at least the LED of the cable stops
blinking). AND the process who does the reading (cat, dselect, apt-cdrom
.. ) stops and cannot be killed (even kill -s 9 doesn't work). Of course
unmount doesn't work, either. Even when I plug the usb drive off, the
problem remains. Once I even got kernel panic the debug message said
something about not being able to follow a NULL pointer, unfortunately I
was in a hurry and haven't had the time to copy it.
Afther that experience I installed a new kernel (from the internet ormal
tar.gz not debianized) 2.4.14 same configuration. The problem remains but
now it already starts when mounting the cd.
I believe this is a bug in the driver but I'm not sure which one though I
decided to post my problem in this mailing list. Please if anybody knows
anything helpfull tell me. Even if it's just the mailing-list I should
post it.
Benedikt
