You may have hit on something here.

My home desktop has two nvidia MCP61 USB controllers on it, one
running the ohci_hcd driver, the other running the ehci_hcd driver.
There are 7 working USB ports on the box (#8 doesn't work), but they
all function the same way (double operation required).

The Dell test machine has eight Intel 82801JI USB controllers, 2 using
the ehci_hcd driver and the other 6 using the uhci_hcd driver.  Three
are 8 USB ports on the box that all behave exactly the same way
(single operation).

I'm still not sure how much that means, but the differences in the h/w
may be significant.
