Hi David,

Thanks for this great info.
I am able to backport USB stack from 2.4.26 to my
2.4.18 kernel.

...
I am using NEC USB2.0 Controller (EHCI). I enabled all
three EHCI, UHCI and OHCI controller through
menuconfig.

When system comes up and I look at
/proc/bus/usb/devices file, it does not show EHCI
RootHub. It is showing only two OHCI RootHubs.

Why am I not able to see EHCI RootHub Port?

Either you didn't load that driver, or there was a problem with your backport so that it couldn't initialize correctly.
