P3 "USB DEVICE REMOVED"

[Jean-François Ménard]

Hi,

I’m using my USB keyboard with the P3+SVGAboard. The keyboard works great until I power off the P3 then back on. I always have a message on the external VGA display « USB DEVICE REMOVED » and the keyboard doest not work until I unplug the keyboard and plug it back again.

When I turn on the P3, I always see the keyboard usual init flashing green led. When in the terminal mode, I cannot see the K until I unplug then plug again the keyboard.

Any idea ???

Regards,

I still do not get it.

What could be different in the initialization process between « to plug a USB keyboard when the P3 is already running » and when the P3 start with a USB keyboard already plugged in ???

I’m very curious to see if another USB initialization state could be added or checked when a user manually enable the SVGA DATA window ON and OFF ???

I guess Wayne or someone involved in the P3 software development could answer this…. hopefully.

Best regards.

I'd try a different USB keyboard. It may be that your keyboard doesn't boot
up fast enough or has some other timing issue with the P3 USB device
enumeration procedure.

USB isn't a simple serial connection. And a Keyboard is a computer. Welcome
to the modern world.
