Web search comes up fruitless except for references to the kernel source code which I don't understand. ;) Thanks, John.
Hi John
Apply the patches and follow the instructions here for BeagleBone Black kernel: http://www.coreboot.org/EHCI_Gadget_Debug
In coreboot menuconfig, the selection of usbdebug dongle 'BeagleBone' is only for 'BeagleBone', not 'BeagleBone Black'. I better add option for 'BeagleBone Black' to avoid the confusion. Select 'Net20DC compatible' for now.
Also in coreboot menuconfig, under 'Debugging', enable verbose usbdebug messaging. Of course you will need another working console to receive those messages, CBMEM console will do if your target system is able to reach OS.

Hi Kyösti,
Man, you are quick. :)
Yeah, I followed those instructions. The BBB's kernel and modules have been compiled with the patches.
Ah, that explains part of it then, because I had selected Beaglebone as opposed to NET20DC or compatible.
It isn't able to reach OS, but if changing the coreboot menuconfig doesn't fix it I shall try it on a Chromebook which is working with coreboot, and revert.
Thank you!
John.
