Will USB 2.0 work with the Linux 2.4.xx kernel?
I believe I heard it wouldn't, but I just wanted to make sure..
And if it isn't compatible, what's a good, inexpensive USB card to get? I only need 2 ports, and the MOBO i'm getting has 4 USB 2.0 ports, and no 1.1 ports.
Thanks!

What gave you that idea? Read this

Hmm, I thought I had read that it wouldn't work, but I guess not.
But, this says to use 2.4.21-pre7, and I can't upgrade from 2.4.20 because of the drivers i'm using for my wireless USB adapter - for some reason they freeze Linux when I attempt to use another version of the kernel.

It doesn't say you actually need 2.4.21-pre7. It just say's it has some improvements so you can have a better experiance.

This is what I found in the FAQ :

Q: Does Linux talk to USB 2.0 devices?

A: Yes, in two ways. First the backward-compatible way: all high speed (480 Mbit/sec) devices can be used at full speed (12 Mbit/sec) in all current Linux kernels. Second if you have the EHCI driver, and a USB 2.0 host controller (EHCI, currently available as add-on PCI cards) then you can use these devices at high speed. EHCI support is available in the Linux 2.5 development kernels, and also in 2.4.19 kernels. (The 2.4.19 code should handle USB disks nicely, but for more complete USB 2.0 support, use 2.5 instead.) At this writing the EHCI driver is labeled "experimental".

If it is in 2.4.19, it's probebly there in 2.4.20 aswell (not sure though). You can install more then one kernel. At the lilo (or grub) prompt, you can chose which one you whish to load.

I know you can install multiple kernels, but for some odd reason my linksys card locks up when I try to use a kernel I compiled.
Thanks!

Oh well. I hope I awnserd your question. You can use usb 2.0 with any kernel. But it might not work at high speed. To use it at high speed, you need the EHCI driver which is still experimental.

Yeah, you answered it.
I don't need to use highspeed devices anyways.
