Version 0.2.1

  • 0x06: Bump customer use word
  • 0x32: Reduce maximum source current to 0.9A

1.5A (7.5W) for a peripheral is a lot to ask from a battery that also has to power the whole phone itself, making it suspectible to power brownouts on device plug in. USB3 requires ports to provide at least 0.9A, so use that as maximum current.
