I guess so. I did not receive any error message until I inserted a
usb-storage device. And even if it was plugged in before I insmodded,
lsmod showed a successful insertion.

I think it means that you inserted it in slot #2 (do you have 2 USB slots?)

It means that the camera was a little too slow to respond to the PC, so it
sent its request again. (because it timed out the first time)

That is good.

I've seen this before. I think it means that your svgalib version doesn't like
Linux 2.4. You will probably need to upgrade svgalib to use it with 2.4.

This is a different issue. I did not include networking support because
I used the SW10.2 lowmem.i config and modified it. This config does
not have networking support or loadable modules.

It is intended for IDE hard drives, not zip drives.

You should be able to use a newer svgalib. Or perhaps there is another
way to view photos at the command line. I thought that it was possible
to use zgv without svgalib.

libcaca might work.

It is not a bug, it is a feature.

At 436K, this kernel is mainly a kludge to quickly use a mass storage
device. If you need to do other things, you should either build your own
custom kernel (or wait for me to build one) or use the large Slackware
kernel.
