[edit] Wasn't able to use pUSB on ZOOM3

I could not get pUSB to work. I eventually saw that for a moment, the ZOOM3 seemed to show up as vendorID=0x451 and productID=0xD00E (just for a instant) via the USB port next to the HDMI cable connector.

I modified the source code to look for productID 0xD00E since the code (as of this writing) was hard coded to 0xD008. It then seemed to be found. Output was:
