James, I bought the Arduino from Amazon about 1.5 years ago. It had been working OK but my problems began with OS10.8.  Now I do not have the USB option from the Tools>Serial Port, only Bluetooth. Arduino only installed Bluetooth options in the Tools menu.  I checked my Macbook, OS10.7,  and it only has Bluetooth options in the Tools>Serial Port menu, no USB.  I tried Arduino versions 1.0, 1.01. and 1.0.2.  My Mac and Arduino do not play well together.

Hmmmm, Same problem here. I cannot find the USB as well

Then it is not a Genuine Arduino, so many bets are off.  You need to determine what kind of USB to Serial chip it is using.  Don't bother looking at the official Arduino documentation.  Actually, I wouldn't trust the documentation the seller provided either.  You'll have to look at the actual chip.


Arduino only installed Bluetooth options in the Tools menu.

"Arduino" does not install serial ports.  The Arduino IDE simply lists the ports provided by the operating system.

Probably related to the fact that it isn't really an Arduino, but a cheaply made clone.

I've got the same problem with a brand new official Uno board bought from Mouser that works fine on my work laptop Win 7.

Brought it home to use on my iMac running 10.8.2.  IDE 1.0.2 runs fine, I select /dev/tty.usbmodemfd11 and when i try to upload a sketch i get the message:

Serial port '/dev/tty.usbmodemfd131' already in use.  Try quitting any programs that may be using it.

and then the report from the IDE:


Binary sketch size: 1,084 bytes (of a 32,256 byte maximum)
processing.app.SerialException: Serial port '/dev/tty.usbmodemfd131' already in use. Try quiting any programs that may be using it.

I've tried using 1.0.1 of the IDE without luck.  I also get an extremely quick pop up window message that i cannot read when i start the IDE.

Can anyone help?

Try using the lsof trick I mention here, to see if something is holding the serial port open.

Also, your problem isn't not the same as the others in the thread, you really should have started a new topic.
