That's not exactly correct. There is a GPL tool, omapfl, that
flashes bare 5912 thru USB. Of course, the 1710 might have completely 
different ROM.

In the 5912 there is an external pin that selects booting from internal 
ROM (for USB flashing) or from flash (for normal operation), so I am not 
sure this is what the nokia flasher does.
