Strange USB issues...

I have a Pentium 200Mhz AMD Bios (home machine):

USB 1.0 - 2 ports

The bios has 2 options:

Enable USB controller and enable USB legacy stuff.

If I turn on USB and boot to a Linux kernel WITH NO USB support compiled in. I get:

1) Slow loading of kernel into memory on bootup
2) AT keyboard timeout (?) errors and no activity with the keyboard (shift lock/numlock/scroll lock). I have to reboot to correct the problem by disabling USB in the bios.

I'm not sure why this is happening, if anyone else has been noticing this please let me know or would like me to do some debugging :-)

Ouch. Watch out when using a hub. They generally want 1.1 support.

Do you only have a USB keyboard, and no PS2 keyboard attached? Is the "Enable USB legacy" stuff enabled in your bios?

Does things work better if you load the usb host controller for your machine?

thanks,

Here's the mobo specs (im home now)...

AcerOpen AP53(AX) Motherboard:
AP53R3C0

One USB connector for 2 ports
Dallas DS12887A or DS12B887 RTC/Battery.

Motherboard supports PS/2 mouse
AT Keyboard
IrDA - Laptops, PDA, wireless stuff 115Kbs transfer rate at 1 meter.

PCI 2.1 Compliant - OFF because some other weirdo issues USB Functionality:

NOTE from booklet: USB Shares INTD with PCI slot 4 therefore if you enable USB only PCI cards that do no not require IRQ such as VGA can be installed in SLOT 4. The PhP BIOS assigns an IRQ to VGA only if the VGA requests for it...hmmmmm
