Hello Just received my pscan.eu box and receiving the error message of: "Interface failed: Interface not powered"I understand from previous entries that this should only happen when the interface is not plugged in to the OBD port on the car, however in my case it is. I have the green flashing light, everything seems to be correct, still the software gives me the error. I'll try to do it on a Windows PC during the weekend, but any advice would be appreciated . Oh, an important side condition, the car is currently immobilized for some unknown reason, would this impact the software not to pick up the signal from the car? Regards, Akos

The flashing green light suggests that the interface is powered, whilst the error message comes from the MacOSX driver for FTDI chip.
I am guessing that there is a bug in the OSX version which we will need to investigate and fix.
Could you do a final check that you have +12V on pin 16 of the Obd socket and 0V on pin 4 or 5?
It would be even better if you can put a 5W bulb from 4 to 16 and verify that it lights up.

Please do the following:- Plug in the pscan interface box into your Mac. Open terminal (from Finder->Applications->Utilities->Terminal) In the terminal type this Code: system_profiler >> Documents/system_profiler.txt Let this run for a minute or so. Now in finder go to your Documents folder and open the system_profiler.txt If you search for FTDI in there you should find something like this Code: AppleUSBFTDI:
Version: 5.0.0 Last Modified: 15/04/2017, 02:43 Bundle ID: com.apple.driver.AppleUSBFTDI Loaded: Yes Get Info String: 5.0.0, Apple USB FTDI driver Obtained from: Apple Kind: Intel Architectures: x86_64 64-Bit (Intel): Yes Location: /System/Library/Extensions/AppleUSBFTDI.kext Kext Version: 5.0.0 Load Address: 18446743521872300000 Loadable: Yes Dependencies: Satisfied Signed by: Software Signing, Apple Code Signing Certification Authority, Apple Root CA
Please compare the above with yours and tell me if there are any differences.

I have tested with my old Macbook compared with a less old one and I can see that Apple have changed how the driver reports the FTDI status lines to the application.
It would seem that the way that we detect the chip status is not safe in MacOSX anymore.
The solution for now is that we will disable the power present detection and push out an update.
I will reply here once this is done.

Thank you so much for the instant fix! I don't have access to the car right now, but tried it with only the interface connected to the Mac and it did the update, and I could proceed to the next screen. Will try to get access to the car tomorrow, otherwise on Monday for sure. Thanks again!

I'm super happy with the device / software, works perfectly now. Connects to all ECUs with no problem, reads all error logs and live data. Was also able to fix the immobiliser issue too. Thanks a million!

Good.
As you have a version of the Apple USB FTDI driver that I don't have, I might write some software later on to test the FTDI status lines and get you to try it with your Mac.
It would be nice to re-instate a meaningful warning if the unit isn't powered, but I need to understand what is going on across multiple software versions first as it needs to be reliable.
I wish Apple didn't change things without warning like this.
