EHCI debug that supports both Linux and Windows as a host PC

[Аладышев Константин]

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.
