For EHCI debug, the basic requirements are that it's a high-speed capable device and that you can configure and use it with <= 8 byte transfers. Usually this applies to Android devices and some have been used already for debugging. You need the `g_dbgp` gadget driver. This driver is reported to not always work, however... a workaround could be to use `g_serial` and add some support code to the debug target.
