My brand new APM 2.6 was working yesterday, and now when I plug it in to multiple computers with multiple cables it doesn't even register over USB. Here's a summary:
-The board lights up when connected to USB, the red and blue lights flash, but the TX and RX dont' light up.
-The APM does NOT show up in the Device manager, the computer has no response at all to the board
-I tried reflashing the USB encorder chip (ATmega32U2) using instructions here:http://copter.ardupilot.com/wiki/common-ppm-encoder-apm2x-atmega32u2/. The "Flip" program is unable to recognize the chip, and throws the error "AtLibUsbDfu.dll not found.".
I've emailed 3DR tech support, no response yet, please help!
Try connecting using 3DR Telemetry Radios if you have them.
Yeah I wish I had some. Was looking at buying some last night but they aren't cheap! It may be worth it for the future though.
Are there any places on the board that I can check voltage to rule out hardware failure?
