Hi, What hadware version are you using? Note that USB0 is run by Arduino to WP connection.

It is a unit from the Innovation Summit last year. How do I check the version? The same happens whether I plug the FTDI cable into the USB Host socket on the main board, or the one on the IoT connector.

I would recommend moving to DV3 board as we dont support very early hardware. The Innovation Summit hardware was early hardware. The USB issue could be due to the fact that USB0 is used in firmware to talk to Arduino in DV3 and onwards. PCB that show rev 7 and up will be supported by us.

But, surely, if ttyUSB0 was being used for the Arduino connection, then plugging in the cable would show up as ttyUSBx where x != 0 ?? If it’s correctly recognised that the device has been plugged in, what would prevent it from being assigned a proper /dev/ttyUSBx identity? If seems to be a Linux …

I got a new mangOH - yes, it does work with the FTDI cable, creates a /dev/ttyUSBx and I can send & receive stuff to the port from the command line. :grin:
