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 ^ permalink raw reply [flat|nested] 2+ messages in thread

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 ;-) Matthias On Monday 25 August 2008 20:55, mike zheng wrote: > Hello, > > I am using ISP156x USB PCI controller with Uboot.
