It isn't tied to hardware but just software revision. The change was also for the HID mode and not the SCSI mass storage updater thing. That would have happened with the current public release.

The basic reason was that windows was not recognizing there had been a change even though the underlying protocol specified had changed and modified with certain usb3 drivers when the device attempted to reboot and come up in update mode. On usb2 it did not have that issue. Thus the updater would not trigger the win usb stack to change drivers.


Although I work for HP, the views and opinions I post here are my own.
