Serial port not found on Lion 10.7.5

I have what looks to be a completely legit Uno R3 fresh out of the box and the software can't see my serial port.

I've tried editing the preferences file to set the device manually, but no joy. Starting the application with the arduino plugged/unplugged makes no difference.

I see this from system information:

Product ID: 0x0043 Vendor ID: 0x2341 Version: 0.01 Serial Number: A4139363831351210260 Speed: Up to 480 Mb/sec Manufacturer: Arduino (www.arduino.cc) Location ID: 0x9c200000 / 2 Current Available (mA): 500 Current Required (mA): 100

Since this is an R3, there should be no need for FTDI drivers right?

One more thing is that when I connect the board to USB, the green light comes on and the yellow light flashes. I assumed this meant a board without a sketch loaded. Am I wrong about that?

(I bought this through an Amazon link from Mp3Car Store. There are 65 reviews, largely positive and no complaints, so I don't think it's a rip-off.)

Update:

The board appears to be fine based on uploads working from a windows7 system. The blinky LED appears to be due to this board shipping with the Blink sketch running.

I can see others have essentially the same problem I do on other versions of OSX, but the only concrete suggestion has been to load the FTDI drivers, which shouldn't be needed to talk to an R3.

Anyone?

I have 10.7.5 (Snow Leopard, I think) and don't have any problems. I think a lot of the Arduino developers use Macs so it isn't really a widespread problem. Do you have VMware or similar installed?

The Console logs might have something interesting if there's a problem starting the usb service. Applications -> Utilities -> Console.app.

I see this in the console log when I first plugged the arduino, before I started the app:

Well that is how it looks when the USB setup fails, all right. I believe you have cause to ask for a replacement.

I'd do that except for the whole works-on-windows part :(

Hello All, Just saw your dilemma as mine!

Been having this problem for 10-11 months. I have several hard drives in an older 2006 Macpro 1,1 The Three with a [u]clean installed SL/Lion 10.7.5[/u], boot drives, works fine and I see the all types of newer Uno Rx Arduinos and older one's with FTDI drivers installed.

I know the older hosed bootdrives system( I have two),are really beat it up, so I'm not surpised. Timeline OS/OSX upgrade 9.x>10.0>10.1>10.2>10.3...updated to 10.7.5 etc... then the migration to a clean OS 10.7.5 always messes up the serial ports again.

The sucess part is I have used Prosoft Drive Genius 3 (trial/demo available direct and on OWS/Macsales site) to partion a drive to install more than one boot disks to a single drive (no RAIDS). Progam moves partion with out reformat(most of the time)! It can be done with 'Disk Utilities' but you must backup and reformat then bless partitions... yak yak yak...

I have a newish '08 Macbookpro 2.8GHz with ML 10.8.2 and all is well. It has both Parallels and VMware on both.(this is a dualboot as well with win7 on it)

Your board is fine if you can see in Windows, did you try a 30day trial of Parallels and VMware (Oracles VirtualBox is free, but is still on the on-ramp as far as I recall). Just a FYI I have seen posts on the Linux side as well, for about a year. Mainly under "grayed out Tool>Serial Menu' Subject line"

Hope it helps..BC
