Re: [U-Boot] NEC OHCI chip bug
not sure if the PCI bus number plays a role here. In our case the PCI window size was not set correctly so that the OHCI access to the PCI bus/RAM was refused.
I found it strange that 2 devices are detected, and we can get descriptor from hub descriptor. And the "Unrecoverable Error" is occurred when getting device descriptor from keyboard. So whether this still relate to PCI bridge setting problem?

detection might work without PCI slave-initiated transfer and the root hub is OHCI internal. But - just guessing. If you have double checked the window there are no more ideas from my side.
