What is the easiest and most stable way to do debug through EHCI USB port instead of COM port? Is there any EHCI dongles on market that supports both Linux and Windows as a host PC?
The answer varies depending on your exact needs. If you are targeting only on coreboot log obtainment, the RaspberryPI/BeagleBone with dwc2 is probably cheapest cross-platform thing to use. For kgdb, this setup *should* work, but this would add another level of complexity due to gdbserver spatial localization :) I`ve never tried working with combination of the RPI and usb-ip to pass dwc2 port over cdc-ethernet connection, this is the only major difference between 'real' dongle and cheap board-based setup.
