USB Boot Mode
The iAudio7 has a USB boot mode, you can enter it by holding down the 'mode' button while plugging in the USB connector. The Vendor/Product id changes to a TCC specific pair (Vendor=140e ProdID=b021), it is then possible to upload code to the device via tcctool (source available in svn tree: http://svn.rockbox.org/viewvc.cgi/trunk/utils/tcctool/
The OF does the flashing, so a bad flash will ruin the player until we figure out how to do the USB boot mode properly.
