Thanks for the suggestion... Vendor reported it was an FTDI device, so digging a bit deeper I found that this works correctly: # modprobe ftdi_sio vendor=0x0403 product=0xdd20 [17261232.336000] usb 4-1: new full speed USB device using uhci_hcd and address 4 [17261232.484000] ftdi_sio 4-1:1.0: FTDI USB Serial Device converter detected [17261232.484000] drivers/usb/serial/ftdi_sio.c: ftdi_sio_attach [17261232.484000] drivers/usb/serial/ftdi_sio.c: ftdi_determine_type: bcdDevice = 0x400, bNumInterfaces = 1 [17261232.484000] drivers/usb/serial/ftdi_sio.c: Detected FT232BM [17261232.484000] drivers/usb/serial/ftdi_sio.c: create_sysfs_attrs [17261232.484000] drivers/usb/serial/ftdi_sio.c: sysfs attributes for FT232BM [17261232.484000] usb 4-1: FTDI USB Serial Device converter now attached to ttyUSB0 cheers, Adam -- Adam Laurie Tel: +44 (0) 1304 814800 The Bunker Secure Hosting Ltd.
