Hi all,
While backporting the latest USB support in U-Boot to support USB 3 hubs I decided to try the latest U-Boot for Octeon which should contain everything. When I start USB, however, with a USB 3 thumb drive plugged into a USB 3 hub, I am seeing a crash. I have enabled all of the debugging support for usb.c, usb_hub.c, xhci.c, xhci-ring.c and xhci_mem.c
In my backported code which is a bit hacked up due to the lack of DT support, I am seeing it fail when it attempts to set the hub depth. Note that everything works fine with a USB 2 hub. I was hoping to compare the stock U- Boot with my hacked up code to track down the issue.
