I couldn't get it to work properly either, personally i'd uninstall 409 and install 311.2 which is the version i'm now using, with my Alpha-bid USB cable.
You will also need Windows XP home should do it, cos i couldn't get win2000 pro to accept the FTDI USB drivers. from here http://www.autonostics.com/pages.php?pageid=3
To summerize what i found to work
Windows XP (home)
Alpha-bid USB cable (£3.99) + P&P
Ross-tech 311.2 software version (free)
FTDI USB drivers listed above (free) top one not the alternate driver.
you'll more than likely need to go into device manager and change the com3 port settings BAWD rate from 9600 to 4800. cos I couldn't get it work at 9600
You'll also need to buy a license from Ross-Tech at $99 (£50) to get any access to your car, cos the free software won't allow you to change any settings..
I must admitt it was a right pain in the butt, trying to get it all working properly, but now i have.... was it all worth it... probably cos it allows "you" to do it and not have to pay someone else, but once you have done what you want, it's done isn't it.......
And my local SEAT garage quoted £40 & F1 in Brighton quoted £30, all in all it all cost me £62, if you don't add the time and replacing broken bits on my laptop... which cost me a further £60 odd squids...
i have a cable and have the driver but when i test all the com ports they all say "interface not found".
im stuck
I have a Keyspan USB serial converter cable - www.keyspan.com
P/N USA-19HS
It was not cheap either and I bought it from the VAG com site and it still does not work
Huh? Ross-Tech does NOT sell USB<->Serial Converters.
In fact, our FAQ states the following:
"USB<->Serial converters are often unable to handle the baud rate and timing requirements that are demanded by many control modules using the VAG protocol. We have had very poor results with most available USB<->RS-232 converters, therefore USB<->Serial converters are "Not Supported." Please do not ask us for technical assistance if you are using one of these converters."

I'm beginning to wonder whether i should have bothered Tbh...
I tried both 409 & 311 versions with the Alpha-bid USB cable and cannot for love or money get my lappy to work on any com port, using W2K pro, so I'm in the process of installing XP, to see if thats the difference it needs and will try using the drivers I've downloaded from the posts above and see how we go......
What bugs me, is the cable I bought; I got because I saw another post on here from a guy who's bought the very same and said it worked for him, so I must be doing summat wrong then, and I'm supposed to be an IT bod and if i can't get the thing to work, how the hell do others manage it
