Hey guys I got something weird going on.
Last week this board ran fine. Saturday I wanted to bring it out
of the OP software into the LP software.
I plug board in and it goes through its normal startup, lights blinking
USB recognizing and you see the RX/TX lights kick up in GCS and
then pretty much nothing.
I get 1 TX light and nothing in GCS shows this board nor can I even
try to flash it, all of the buttons Halt, Boot Rescue are greyed out.
So I took the board back to the guy I purchased it from, he hooks it up
to him MAC and the board boots up like there is no problem at all?
Yet I have tried 4 different cables and 3 other CC3D's (mind you all of them came up no problem)
I totally uninstall OP the drivers....LP and it's drivers and clean installed LP.
HELP?

Yes sir I did but may want to try again since later before
going to bed I tested the board on my PC (was on my laptop previously)
and the board connected fine.
So this could still be a driver issue.
I will pull everything out again, remove the driver as per your link
in the event I may have missed removing the hardware correctly.
Will let you know how it goes.
Thanks

If i remember some users needed a reboot after removed the driver... windows issue.
