Installed the driver again and then I could see one of the two devices I had purchased. (both of them were Prolific devices according to System Profiler) Now when you plug in the device, a device entry appears in /dev. The SerialPortSample program can find the device! Hello Allen, congratulations, your device made it. It is unfortunately quite a mess with the USB to serial devices. Even though practically all devices you can find (iogear, keyspan, Aten) use the prolific PL2302 chip-set, you have to rely on the vendor to supply an up-to-date driver, that's the theory and the legal contract at least. Unfortunately some of those Venduhs prefer (or at least in the past preferred) to bitch about how unstable Apple's USB kernel Interface was, instead of doing something. If you have a device that doesn't work (due to lack of updated driver), and uses the prolific chip, there is a way to fix that driver [1] : 1. Locate the USB Vendor and Device ids of your USB-to-serial device using System Profiler 2. Edit /System/Library/Extensions/ProlificUsbSerial.kext/Contents/ Info.plist to change idVendor and idProduct (don't forget to do a hex-

dec conversion)

3. Reload the extension And presto you have a driver, for a device whose product manager is still twiddling thumbs on a Leopard compatible driver. Question: This time when I rebooted the system after installing the driver it said, updating the boot cache. I did not notice this message before. Should this always appear when installing a new driver? Perhaps this will be a clue in the future. This email sent to site_archiver@lists.apple.com
