Hallo Dave,

why are you listing only one OHCI controller from the pci.exe output when in
fact you have 2 of them ?
I will have to look into the detection logic (obviously HCIMONIT is able to
detect them, I'll have
a look what it does differently from what the drivers do ...).
I assume you DO load OHCI drivers from config.sys ? In what order do you load
USBOHCD.SYS / USBEHCD.SYS ?
Can you revert the order and retry ?

Are you saying that on your system you have NO UHCI even though you have EHCI ?
In other words: EHCI "builds
on top of" OHCI and not on UHCI ?
