The higher level interfaces are all in place and there are drivers for different controllers such as OHCI and UHCI. Some of these controller drivers are still board dependant, but we're in the progress of merging them together into one generic driver. If you happen to have an OHCI Controller, don't miss "doc/README.generic_usb_ohci".
Is there a plan to support EHCI as well?
There are already boards supporting USB 2.0. Grep for "USB_2_0_DEVICE".
Marcus - of what I've seen (in the USB tree), the USB_2_0 support is for a CPU specific (4xx) EHCI controller. My question was about a generic EHCI controller driver (like the OHCI one), as we plan to use a PCI based USB host controller. I guess we can operate it in the OHCI mode at boot stage and get a slower boot if generic EHCI support is not planned in the near future.
Best regards, David.
