Do ISA USB Cards exist?

Somethign silly here.

A Guy came to me just now, asking for a PCI USB Card...

I gave him it, but he brought it back moaning that it wont fit.

After some talks, I showed him an old AT Mobo and it turns out that its ISA and NOT PCI.

I said that I seriously doubt that they do exists, because ISA was phazed out before USB came in, or at least they were close to that, and that its unlikely that they do exist, but just in case I am wrong, does anyone know if they do or not?

As far as I know, PCI was introduced to allow IRQs to be shared, therefore supporting “plug ‘n’ play”. PCI allows for several devices to share an IRQ as it uses it’s own interrupt system. Since the old ISA cannot share resources, I would think the answer in no. USB is not available on an ISA bus. Windows 95 release B and later supported IRQ sharing.

I thought not.

As for the IRQ Sharing, I had thought about that, but didnt mention it just in case I was wrong.

Cheers all.
