d. USB cable
OSD can work with any kind of serial cable at TTL standard ( 0V - 5V only )
It can be any RS232-UART bridge made on MAX232 or similar chip , or any USB-UART bridge doing the same .
There are few manufactures of USB-UART chips on market .
With OSD are delivered types of cables as follow, you can identify each by label on particularly cable :
OTi
Prolific
MCCI
OSD will work also with :
ArkMicro

Each type of USB cable need to be installed on PC .
For each type we must use proper USB drivers - so for Prolific we must use Prolific , for MCCI we using MCCI etc.

Very popular is FTDI cable, so it is used for many other devices and also can be used for OSD, cable from Ardupilot also , it is almost pin compatible with OSD .

USB drivers installation problem
When you have USB drivers installation problems under Vista or Win7 64bit - you can run virtual machine with installed regular winXP 32bit on your PC from Microsoft .
here is the link http://www.microsoft.com/windows/virtual-pc/default.aspx
Some of basic type Windows systems not allow to use those MS virtual machine , so you can use a very good virtual machine named VMware http://www.vmware.com/ - what in my opinion is very nice solution , allow to run any winXP , Linux or even MACOS on your PC .
That is general solution for any driver-software problems under 64bit Win systems .
Look at Free Products, VMPlayer is free http://www.vmware.com/products/player/overview.html
If still have problems - you can write to MS and ask them , why they made system not compatible with previous versions .
