I just received my APM 2.5 yesterday. I pluged it directly into my laptop (win7 64bit). Howerver it did not autodetect. Bringing up the device manager initially showed no com port options. However, I did manage to download and am now showing Arduino Mega 2560 (com8) in device manager. However there is an error code associated with the com port, Device status: "This device cannot start. (code10)".
any ideas on a possible solution?
Did you run the Mission Planner installation program (which will load the right drivers) as instructed in the manual?
Yes I ran the program, windows doesnt seem to reconize the device at all, Hmmmm?
Fixed, bad usb cable :)
Glad to hear you got to the bottom of it. Thanks for the update!
