I have one of the 'original' Flex control Knobs. It has the "by K6TD/K6TU" label down in the bottom right corner.
A couple weeks ago, neatening cables and such, I unplugged a working 'Knob'. I've tried a number of USB ports on the F6500, or other devices on this ham radio only computer.
All these other ports result in a momentary brightening of the Knob light which immeadately goes out and I have no vfo, or any operation from any of the Buttons. I hadn't used it that much as I had vfo control via mouse but I do wish to again use it for other adjustments.
Anybody know if I 'killed' it...can't see how plugging it into a different USB port would cause that.
And of course I can not find the original disk that came with this Knob way way way back when.
Open to suggestions. Feel free to email be direct firstname.lastname@example.org
