Hello,
I am using ISP156x USB PCI controller with Uboot. Right now, the code
can find only 1 root hub when I use "usb inf" or "usb tree" command to
check the USB tree. If I list the PCI device, it shows there are 2
OHCI and 1 EHCI host controller. Anyone knows why I have only one root
hub? What shall the USB tree looks like for ISP156x USB PCI host
controller?
Thanks,
Mike

Hi Mike,
U-Boot currently only supports one USB host controller at a time. So it's
wrong to say that U-Boot finds only one, but correct is, that U-Boot only
uses one.
Commands to switch between different controllers or multi controller support
is missing.
You could add this feature ;-)
