The result was even stranger: Unable to find FTDI devices under given vendor/product id: 0x403/0x6011 Error code: -4 (usb_open() failed) Retrying with default FTDI pid=0x6001. Error: device not found I did lsusb again to make sure the device is connected and got the expected result: Bus 001 Device 005: ID 0403:6011 Future Technology Devices International, Ltd FT4232H Quad HS USB-UART/FIFO IC -- Ori Idan -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details.
