FAO: Galletto/KWP2000/ELM327 Users - Ruan - 31-10-2014
Just a bit of an FYI...
Some of you may have heard of the "FTDI Chip" inside these devices - this is the device that allows your computer to talk USB to a Serial device - they're used thousands of devices and as far as I'm aware, are used in the Galletto/KWP/ELM devices....
Essentially this chip is one of the MOST counterfeited pieces of Silicon going... FTDI can't get supply and demand sorted etc...
FTDI have been caught red-handed releasing driver updates (through Windows Update!) that will (essentially...) permanently destroy your device if it does not use a genuine FTDI Chip inside...
I can guarantee that the £5.99 ELM327 cable from China does NOT use a genuine FTDI Chip - so my advice would be NOT to attempt to update the drivers of it... It's awkward because Windows Update tends to just download them from wherever... But just be warned, I'll let you know when I can definitely say which version will NOT destroy them. The company have released a half arsed statement that essentially says "we won't do it again" - but I wouldn't trust them as far as I can throw them... They're about to destroy the company with that kinda bullshit tactic... There's now probably >100,000 devices now permanently destroyed due to this bullshit!
Just an FYI for if you suddenly find your device with an FTDI Chip broken and not working any more...
What it does is set the USB ProductID to null in e2prom so unless you can work a way of reflashing a null product coded device, it's wrecked.

Cheers for the heads up man.

are the £20 maplin jobies safe?

God knows - as said, it's probably one of the most, if not THE most counterfeited piece of Silicon going - supposedly there's been some BIG companies accidentally buying dodgy ones, they're THAT easy to come by and FTDI and their distributors are so shit at making the genuine product available lol!
They said they'd removed it... So you SHOULD be OK...

For anyone who is really that bored.

ok...so I am in the market for PP2k....does that affect me!? As I may only use it once in my lifetime, I been looking at chinese versions...What should I buy now!?
RE: FAO: Galletto/KWP2000/ELM327 Users - Ruan - 31-10-2014
I don't THINK the PP2K uses an FTDI chipset..
At least to my knowledge it doesn't - happy to be proven wrong, but I didn't think it did...

This is very useful information. If you want the old FTDI driver this should be available with the software on my website, or just use an MPPS and then it uses a different driver.

Luckily I have an xp partition on a virtual machine on my macbook with internet connection permanently disabled to the virtual machine. Hopefully I'll never run into this problem
