10.4: Use an IOGear Serial to USB converter cable
Authored by: autospanker on Feb 26, '06 09:51:33AM
Hey gang! First of all I am new to this Forum. I am a new Mac Intel user and I came accross this forum about getting the USB-to-Serial adapter to work with OS X.

I have a new Intel Core Duo Macbook 2.0 with OS X 10.4.5 installed. I can not for the likes of me get this GUC232A adapter to work. I know this is a new beast but I welcome any sugestions to get this to work. Here is a brief summary of what I do believe t be working.

1.) System Profilter > USB detects USB-Serial Controller (Version 3, Manufacture - Prolific Technology Inc. Product ID- 0x2008 Vendor ID 0x0557

If install drivers and then try to load kext I get the following.

************** 26com_prolific_driver_PL2303 is not compatible with its superclass, 18IOSerialDriverSync superclass changed? kextload: a link/load error occured for kernel extension /System/Library/Extensions/ProlificUsbSerial.kext load failed for extension /System/Library/Extensions/ProlificUsbSerial.kext (run kextload with -t for diagnostic output) **************

If I use the mentioed -t option

************** kernel extension /System/Library/Extensions/ProlificUsbSerial.kext has problems: Validation failures { "Executable file doesn't contain kernel extension code" = true } **************

I have tried the driver: PL2303_1.0.8.pkg and PL2303_1.1.0b1.dmg

Neither work.

I tried installing the drivers on a MacBook Pro and it caused the hang on reboot. It wouldn't get past the gray screen. It was pretty terrifying for a while.

Luckily, I had another mac to mount the MBP (via Target-disk mode). I was able to find the offending KEXT and delete it. Boots fine after that. Whew! If I didn't have another mac to do this with, I'd really be hosed.
