Macbook Pro Late 2008 usb to serial cable stops communicating after Yosemite upgrade

I recently updated my MacbookPro to Yosemite and have found that my usb to serial cable no longer works. I've tried reinstalled drivers multiple times with no success when I connect my Gigaware usb to serial cable and conect my cisco console cable which used to work fine on Mavericks but now I get no output in my terminal program secureCRT.


I when my cable is connect I see the following in dev


hugh-millers-macbook-pro-77:dev Yogi$ ls tty.*

tty.Bluetooth-Incoming-Port tty.HughsiPhone-WirelessiAP

tty.Bluetooth-Modem tty.PL2303-00002006


hugh-millers-macbook-pro-77:dev Yogi$ ls *PL*

cu.PL2303-00002006 tty.PL2303-00002006

hugh-millers-macbook-pro-77:dev Yogi$


Here is what I see in System Information


USB-Serial Controller:


Product ID: 0x0fba

Vendor ID: 0x05ad (Y.C. Cable U.S.A., Inc)

Version: 3.00

Speed: Up to 12 Mb/sec

Manufacturer: Prolific Technology Inc.

Location ID: 0x04100000 / 4

Current Available (mA): 500

Current Required (mA): 100


SecureCRT is set to use /dev/cu.PL2303-00002006


Has anyone experienced this issue, can anyone assist?


Mac Info

You can use this : http://www.macupdate.com/app/mac/51344/serial but let me tell you that last night I found the way to do it with Coolterm for free http://www.macupdate.com/app/mac/31352/coolterm


I think that the problem is the installation , you have to copy to sudo kextload /System/Library/Extensions/ProlificUsbSerial.kext or in my case I used this as reference, now it is working....

Anyone found a solution to get this working consistently in Yosemite? I am having the same issue where I have to have the cable plugged in when I while booting in order to get it to work, then once I disconnect, I am toast and have to reboot with the cable plugged in again. I followed pretty much the same procedure as Pelonas above, I have been using zTerm. Worked great in Mavericks, but just upgraded to a new rMBP with Yosemite and can't get it working consistently.


Thanks
