10.7: Prolific 2303 based USB to Serial adapter drivers

If you have a Prolific 2303 based USB to serial adapter and it no longer works under Lion, installing the Snow Leopard 64-bit driver may fix the issue.

I can confirm the Prolific 2303 64-bit driver works with IOGEAR adapters on Lioin & SL 64-bit.

I use the osx-pl2303.kext (242 KB) dated February 17, 2010 from BJA Electronics on my Lion install and it works fine with my Prolific based USB to Serial cable to control a Pix from the command line.

I tried this, but the driver didn't work for me. In my case, I installed the driver from failberg: https://github.com/failberg/osx-pl2303 Note the warning: "A very unofficial fork of the Prolific PL2303 driver." However, this driver worked when the official driver did not.

Same experience here as johnalex. Official driver worked under Snow Leopard, but not under Lion. Although the driver was loaded (confirmed through About This Mac --> System Report --> USB), "Load My Tracks" could not find my Garmin GPS. |
