I bought the RPi USB to 232 console cable adapter https://www.adafruit.com/products/954. I installed it per the instructions https://learn.adafruit.com/adafruits-ra ... e?view=all, and it works except that it freezes up when I am editing with nano using the Mac terminal. I tried an alternative terminal program and the same behavior, leading me to suspect the driver. I tried it on windows and it worked fine. Problem is that I own a Mac and its not working right on the mac.
Please help.

Re: RPi console cable (product 954)
Should work. All I can suggest is that we try replacing the cable. Please email [email protected] with a link to this thread for a replacement

Re: RPi console cable (product 954)
Looks like the issue is that the driver isn't updated. There seems to have been a known issue for the problem I am seeing on the driver development page
http://sourceforge.net/p/osx-pl2303/dis ... it=25#16b3
Please test one out yourself with OS X BANNED. Just use it to connect to an RPi and edit /etc/network/interfaces
It fails pretty fast for me and just stops responding. Unplugging the usb converter and plugging it back in is the only way to get it working again.
I am also a bit unhappy about the driver support on this thing. The tutorial basically sends me to a source forge where I have to pay $10 for a binary driver. I then pay and download, and I get an error from BANNED saying the kernel extension can't be loaded because its from an unidentified developer. The other link in the tutorial is a free version, but exhibits the buffer flushing issue in the driver.
I tried to download the source and compile it myself, but I couldn't do it. Xcode just threw up some errors and I really don't know what Im doing with this, so I stopped.
It would be nice if Adafruit would go on source forge and compile a Signed binary driver for MacOS X using the latest source to support the product your selling.

Re: RPi console cable (product 954)
Ugh that is super scammy - it used to b e an open source driver, but now they're charging for the driver! First up, you should get a refund, since it doesn't work. We've deleted that link. If you see it anywhere else, let us know, we'll remove it!
Second, try out this official prolific driver
http://prolificusa.com/files/md_PL2303_ ... v1_5_1.zip
from here
http://prolificusa.com/portfolio/pl2303 ... ontroller/
Does that work?

Re: RPi console cable (product 954)
I have the same problem and went down the same route with purchasing the driver, etc. The prolific driver does not work. I've tried on two Macs.. both running 10.9.4.

I just installed the Prolific driver 1.5.1 on MacOSX 10.9.4 and it works for me.
Does your serial cable show up in USB in System Report?

Re: RPi console cable (product 954)
Yes, I also followed the drive instructions to do this in the Terminal...
cd /dev
ls tty.usbserial*
I get:
tty.usbserial
However, when I run:
screen cu.PL2303-000012FD 115200
The screen remains blank. If I close the Terminal session and reopen and try again, I get an error message:
Sorry, could not find a PTY.

I should also mention I'm using a Raspberry Pi B+ and have configured the pins according to the instructions in the tutorial.

Re: RPi console cable (product 954)
Can you install Serial Tools and do a loopback test?
http://www.w7ay.net/site/Applications/Serial%20Tools/
Jumper the white and green wires together to make a loopback, and open usbserial in Serial Tools. Whatever you type should be echoed immediately back.

I installed the tools and jumpered the wires and can confirm it the loopback works. I see the echo immediately.

Re: RPi console cable (product 954)
OK. That means that the cable works and the driver is installed correctly.
I must admit I'm not familiar with the screen command on the Mac. I think there must be something wrong with your command string.
You should be able to communicate with the Pi through Serial Tools. Can you verify that?

Re: RPi console cable (product 954)
When I try to communicate with the RPi B+ via Serial Tools, I see this.
It doesn't do anything after the last line.
I hooked up a version A Pi and everything works as expected. Strange. When I boot up the B+, everything works as expected. I do not observe the unmounted error. Is the file system somehow unmounting when using the console cable?
I also found this post about /etc/inittab
http://raspberrypi.stackexchange.com/qu ... nd-pty-mac
But I compared the lines in both the A and B+ and didn't see a difference.

Re: RPi console cable (product 954)
That's telling you that your image is corrupted. It's nothing to do with the console cable.

Re: RPi console cable (product 954)
Yeah, I don't think anything is wrong with the cable. But if the image is corrupted, I wonder why the Pi boots and functions just fine without the cable. And then when I attach the cable, it reports a corrupted image.
