Anyone running Xen on their laptop for example? Xen also supports printing to a USB debug port (EHCI debug port) [0], but some laptops don't even have the USB debug port accessible, and then you need a special adapter which is impossible to find nowadays. So, the easier way to debug is to get a box with SOL or a working serial DB9 port. Roger. [0] https://www.coreboot.org/EHCI_Debug_Port
