This needs support for usb interrupt transfers, so there are some changes in various USB drivers as well (only usb-drv-arc supports it at this point, others won't have working HID yet). HID is disabled for now, as the apps/ part is not included yet. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20962 a1c6a512-1295-4272-9138-f99709370657
