I don't see any ports in the tools menu, other than two bluetooth ones, which I am not using. I hope someone can help. I think is is a problem with my Mac. During a class, with the same computer I use at home, I had this problem too. It went away eventually after plugging in/ unplugging, or trying different cables. I encountered this problem several times in class. Now, at home, I have the same problem of not having a port appear and thus I cannot connect. I have tried many things but it still doesn't work.
When I connect the board to the computer, the Rx light goes on for a split second and the green on light stays lit.
Mac OS X Yosemite 10.10.5
MacbookPro retina, mid 2012
2.7 Ghz Intel core i7
16gb memory
Sparkfun RedBoard
Arduino 1.6.5
Tools: Board: Arduino Uno (tried other options too)
Tools: Programmer: ArduinoISP (tried other options too)
This is the error when I try to upload:
avrdude: ser_open(): can't open device "/dev/cu.usbmodem1272001": No such file or directory
ioctl("TIOCMGET"): Inappropriate ioctl for device
My mac System Report USB device tree shows:
USB 3.0 Hi-Speed bus
USB 30 SuperSpeed Bus
USB Hi-Speed Bus -> Hub -> Facetime HD Camera (Built-in)
USB Hi-SpeedBus -> Hub -> Hub -> Apple Internal Keyboard/Trackpad, and BRCM20702 Hub -> Bluetooth USB Host Controller
I have two physical USB ports, tried both, tried unplugging and plugging back in, tried rebooting computer, tried restarting Arduino. but still couldn't find a port in the tools menu.
I installed FTDIUSBSerialDriver_v2_3 and rebooted. Didn't fix problem.
I tried two different cables. I also added external power to the board.
I have reset the board too.
I'd really like to get this working.
Any suggestions?
Thanks,
Wendy
