It is highly recommended to always use the most recent driver version available.
Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver.
Problems can arise when your hardware device is too old or not supported any longer.
I fixed it. If anyone is having the same issue with a USB-Serial Controller D with the Vendor ID Prolific Technology (TRENDnet TU-S9) the drives from TRENDnet's website for some reason will not compile successfully in Mac OS X 10.6.7. Go to http://www.prolific.com.tw/eng/downloads.asp?id=31 and download the correct drivers: md_PL2303_MacOSX10.6_dmg_v1.4.0.zip. Once installed your Mac Book Pro will reboot then you can use screen /dev/tty.usbserial to access your Cisco Switches and Routers. Good Luck
