Correct; this piece just adds the infrastructure that lets you then layer the standard USB host code on top. I'm assuming I'll push both the tilegx USB infrastructure, and the drivers/usb/host stuff, through the tile tree. Or, I can push just the low-level stuff through the tile tree and let the USB host stuff go through the usb tree. -- Chris Metcalf, Tilera Corp. http://www.tilera.com
