MacDive Forums

Hi,

I'm trying to get my Suunto Mosquito and prolific PL2303 USB/RS232 adapter to work on Yosemite with MacDive 2.3.6. This combination was working 5-6 months ago before I upgraded to Yosemite (on 10.9), so I'm assuming the hardware is all still good. I've tried the 3rd party drivers but I'm not sure the install works on Yosemite or not.

Does anyone have this combination working? If so what drivers and install method did you use?

There has been success with the third party pl2303 drivers. Perhaps if you're asking others, you could mention what driver you tried, and in particular whether you tried the third-party one?

Someone recently used it and had success with Yosemite.

Nick,

I've tried the driver you recommended above, the paid driver on mac-usb-serial.com, the 1.5.1 driver from Prolific, and the instructions here:

http://www.xbsd.nl/2011/07/pl2303-seria ... -lion.html

I'm worried at this point I don't have a clean install of any of the drivers and I'm trying to make sure I have everything uninstalled cleanly. If there are any references or guidelines that might help with that I'd appreciate a pointer!

I've not heard of any paid driver. I would certainly be avoiding that, however. The free one I linked should be perfectly adequate.

To clean up, you will need to refer to the instructions from the various drivers. For example in the link you pasted, it has the uninstallation instructions. Just follow them.

The link I gave you is the most common one people have used successfully, that I'm currently aware of.

Thanks

Tried to clean up my previous installs and reinstalled the suggested driver using the link provided but I get the same error. The Mac seems to have a serial device that MacDive sees: /dev/tty.PL2303-000013FA . If I have the serial cable unplugged I get a "no valid serial port error", with the cable plugged in I get:

Failed to read header information (Error Code: -7)

Is your device in PC transfer mode? Do you have a low battery?

Try jiggling the connection and downloading a few times. Often the cable just isn't connected quite right.

Yes, I've verified it is in transfer mode and the battery was replaced last week - when I put it in dive mode it shows 4 bars. The cable has always been a little flakey but I've tried moving it around without luck. I"m going to see if I can get it to work on my PC with SDM just to rule out a bunch of things. Would running the "Vyper" diagnostic help?

Not really. These days, the transfer protocol itself is reliable and not the issue. The test is more for debugging data issues (incorrect temperature, depths, etc). Again in the case of the mosquito all of this is pretty robust these days.

The issue is more likely hardware. Dodgy cable, bad contacts, etc or driver. The driver is appearing which is good. I'd try rebooting, and then jiggling the cable a few times and making really sure the contacts are clean, not wet, not damaged in any way.

Here's another data point. I can take the same exact hardware (cables, computer and laptop) and download my dives in SDM3.1 running on a Parallel's VM. This rules out any hardware issues and points back to having some sort of corrupt or conflicting drivers on OS X or something just doesn't work with the MacDive/Yosemite/PL2303 combo.

With another round of driver clean up, a restart, a clean install, a restart and refreshing and selecting the serial port in MacDive (Preferences->Advanced) I was able to get it to work. I can't point specifically to what made it work since I thought I had gone through these steps earlier but something changed or I botched one of the steps.

My configuration:
MacDive 2.3.6
MBA running Yosemite 10.10
Plugable USB/Serial adapter (PL2303 based)
Suunto Mosquito
/dev/tty.PL2303-000013FA is the device created when I have the cable plugged in to the serial port on the right of my keyboard

I used these instructions:

With this driver:

Thanks for the help.
