Hi!,
This has been a problem I have tried to resolve for some time now,
and I was hoping someone could point me to a possible solution that I have
not considered (or even knew about).
A few months ago, I bought an iomega ZIP drive for the parallel
port. After a little bit of work and the ZIP mini-HOWTO, I was able to get
the recognized and working under Slakware (2.0.12 kernel, or something
like that). Recently, I upgraded to red hat, and I have yet to access my
ZIP drive. I have gotten the latest code from Cambell (its funny It was
not provided with the 2.0.29 RH kernel, but with my slakware), and tried
all sorts of things after reading the ZIP mini-howto and the SCSI-HOWTO.
Under slakware, and what the ZIP mini-HOWTO instructs should happen, I
should get a dev address at boot-time. However, at bootime it is able to
recognize the drive is there, but it won't give an address. (see dmesg
output below). I am viewing the problem to be the lack of a dev address
(ex: /dev/sda4), and have been working on all kinds of solution (see
various outputs below). Clearly, the drive is recognized, but the driver
just does not provide a device name! Please help me- what am I missing or
doing wrong here?
