Hello, I don't manage to run more than one FTDI Usb Serial Adapter on a Beagle Bone Black. Since there is only one Usb Host port on the BBB, I tried with several hub (powered or not) or cape. Each time that more than one adapter is plugged, these errors appear (kernel 4.4 or kernel 4.9): [ 1544.135039] ftdi_sio ttyUSB0: ftdi_set_termios FAILED to set databits/stopbits/parity [ 1545.143074] ftdi_sio ttyUSB0: ftdi_set_termios urb failed to set baudrate [ 1550.151247] ftdi_sio ttyUSB0: urb failed to clear flow control Does the issue come from the FTDI driver? I own 4 Beagle Bone Black: the problem exists on all of them. Who should I contact or where should I report this issue?
