  Looking at the "shiny brochure"-level documentation for the TUSB6010
it looks like it has full support for USB-OTG, including a 5V charge
pump for driving peripheral devices.  Whether or not it's possible to
write support for it due to available documentation is another matter.
 I really wish Nokia would step forward and do it since it looks like
it could be perfect for host-mode.
  Thanks for doing the kernel writeup!
