master or slave, switchable manually through software. not otg. there
is a page on the wiki with lots of detail about how to switch it in
software, how to get/make cables, providing/drawing power, etc

shows some of them

there are also a couple of apps at for switching host/slave;
i'm not sure if they work with the new sysfs paths, though
