The hosts (across the country) tell us CentOS doesn't support USB 1 !

I find this unbelievable.

Can anyone set me straight?

Since we have no idea of your mainboard chipset, it might be hard to get knowledgeable people to spend their time on it. I'm not knowledgeable, but have a general background.

Based on the messages, I would check the BIOS setup, as the messages suggest. It may be that the 4.x stuff driver(s) didn't depend on an IRQ while the 5.x might. Just a guess. I guess a conflict is also possible.

If you don't see anything to change and test, I suggest you post back with more info so experienced folks can help.

Thanks.

I don't have any USB 1 ports on my desktop, but my laptop (an o-l-d Toshiba Tecra) runs CentOS5.2 and the USB 1 port on the back works fine. (I don't use it much since I got a PCMCIA USB 2.0 2-port card, which is easier and more versatile, and faster.)
