Usb 5-1: configuration #1 chosen from 1 choice Usb 5-1: new full speed USB device using uhci_hcd and address 2 Ubuntu comes with FTDI support out of the box, and the ELM327 device was detected without problems. ![]() So, in short, the package provides a USB interface on one end, and an OBDII interface on the other. The device that I got further provides a UART interface via its FT232R FTDI chip which provides a USB interface. The ELM327 interpreter chip provides an RS-232 (serial) interface to ODBII data. This is probably why I never managed to get it to work on my car. Update September 9th, 2014: turns out, unsurprisingly, that the board I had was a fake one, containing no ELM327 chip inside, but rather PIC microcontroller that emulated the expensive proprietary genuine ELM327 chip. I finally received the long-awaited OBD II (OBD 2) ( on-board diagnostics) interpreter based on the ELM327 chip yesterday and all I can say is that it’s been a long night. ![]() Most modern cars tap into this information and display it on the dashboard via on-board computers. ECUs ( engine control units) are able to give out a myriad of information, like systems’ fault codes, real-time RPM, air-flow, fuel consumption, voltage, exhaust state, and lots more. However, these inspired me to dig a little into the car ECU. I have been having car problems recently.
