4) PDA - not even found

Was it turned on? Did you tell the PDA to sync with the PC?

I don't know. I think he did what he usually does to use it in
Windows. Should it be recognized as mass storage?

In Windows you usually run some program. In Linux you have
to turn on the PDA, press the hotsync button, and then it
should show up in dmesg.

No, it should be some variant of usb-serial, not mass storage.
We will try this next time.

6) mouse (into the other USB port on the computer) - found it but I
think
we need more modules. I tried insmodding mousedev.o from your modules.

You also need to mknod (I posted about this earlier).

I will look that up. Do you want to include that device in the next
edition?

I will include a script to make it for you, since the device is useless
without the symlink to /dev/mouse.
Will your script make the device and the symlink?

and are not insmodding usb-storage?

usb-storage does not accept vend/prod ids at runtime, at least in
Linux 2.4.31. You must recompile to add unusual device ids.

So this boot disk is not likely to work with all usb storage devices?

Correct. I really want to fix this.
Thanks.

Have you tried Slackware? I believe that Linux has very poor support
of unusual usb-storage devices.

What counts as unusual?

Unusual device IDs. The official USB mass storage document says that
device IDs in a certain range are mass storage devices. Anything
outside of that range must be specifically supported by the operating
system. DOS doesn't support unusual IDs either, does it?

So far DOS has done less than linux.

I will look at the source code and see if I can add a module option
for an unusual device ID.

So is printer.o useful only for detecting the printer's existence, or
what
do we do with it?

insmod it, mknod /dev/usblp0 c 180 0, try sending something to it.
Can you also include this /dev next edition?

Why? It is nearly useless. My inclusion of printer.o was probably
a mistake, just like ppp*.o

Can it be used to determine if a printer is capable of printing text?
I can also try sending it a test file created with pbmtolj or pbmtoeps.

Matrox works (surprisingly well) as plain VGA.
It works even better as chipset VESA.

Does anything you have _not_ work with chipset VESA?

I only tested your new zgv on Matrox and S3Trio3D (both vesa 2.0). I
think some vesa 1.2 cards don't - S3 Trio64V? Cirrus?

So I should include VGA and some others for cards which cannot
do VESA.

For SW71 svgalib, and VESA 1.2 PCI cards, all I needed was chipset VESA. Most VESA 1.2 cards worked without specifying chipset. SiS worked but only at low resolution. Tseng and Trident may have worked at low res, or not at all. I think S3 was messed up if you specified VESA.

I did not test non-VESA ISA cards. They might need the other chipset lines. I sort of doubt anyone is using ISA video with USB.
So chipset VESA might be enough, chipset VGA certainly enough.


chipset FBdev does not work with Matrox or Trio3d - mmap error rrr
Maybe you did not compile it to work with fb and should omit that line.

I think it has FB support. Did you boot in FB mode and mknod fb0? I
will remove the line if framebuffer will not improve compatibility.

To boot with your 1-floppy linux in FB mode would I need to edit
syslinux.cfg?

Yes.

I don't really need fb mode to download or view photos but I will give this a try some time.

I will also test your boot disk on some other video cards, including VESA 1.2 Trident and S3 and ATI and Cirrus. It might be a few days.

Tomrrow I will try it on a USB keyboard, and if I can find your instructions for modules and devices, also a usb mouse.
