NASR-M board bring-up, USB adventures II

USB finally works. Now I’m able to connect an external USB hub to the socket and plug in thumb drives and USB hard disks. All works fine, except the USB-to-SATA converter, which is not soldered in yet. I saved that for the dessert, because I have other priorities. This is the ‘lsusb -t’ picture of a thumb drive plugged into the USB socket.
