Re: Broken USB conector

Once we have enough funds to do a re order. We have to sell off all the cameras we have in stock right now. The whole Kickstarter fiasco only left one viable path for us.

Good news is that we've finally shipped cams to Lextronic and hopefully we will be selling quickly in Europe.

So, if you got a timeout error then that means the IDE was able to open a serial port on the board. Then it sent the firmware version command and got no response. So, the firmware on the cam is likely the problem.
