[Elecraft] USB mouse support for P3SVGA -- please don't neglect the scroll wheel

[Joe Subich, W4TV]

Since the P3IQ will apparently use the USB ("keyboard") hole on
the P3 rear panel, one would hope the hardware also includes the
necessary support for an external USB hub that would support both
P3IQ (external sound card functionality) and USB mouse support.

Although I have never bought into the need for P3SVGA, it would
seem that hardware will also need to be upgraded to support an
external hub and P3IQ/Mouse/Keyboard functionality (and perhaps
the ability to save a screen grab to a thumb drive on the hub
as well).

73,
