P3 - SVGA USB Serendipitous Solution

[Ken Widelitz]

It seems that if you toggle a USB device on the P3, it loses its knowledge
of the USB device and doesn't recognize the device when it is toggled back
UNLESS the SVGA is in data display mode. IMHO this is a firmware bug.

Hi Ken,

I don't understand what you mean by 'toggle a USB device'.  The P3/SVGA board will enumerate a USB keyboard or thumb drive even if the SVGA en is turned off (the display is turned off) OR data display mode is turned off.  I just checked.    You can verify that by opening up the P3 and looking on the SVGA card.  Whenever a USB device is correctly enumerated, the LED toward the connector will light solid.

Kind regards,

Paul

Hi Paul,

 

My experience with the P3 SVGA is that the Genovation USB keypad will not
work unless data mode is on.

Hi Ken,

Yes, the USB keyboard is not active when not in data display mode. I
realize that folks are using the Genovation  keypad as means of
executing macros to control the K3 (and soon the P3), however the USB
keyboard port was designed for data.
