It presents a serial port to Linux on /dev/ttyACMx. However when I plug it into my FreeBSD host, it detects as follows: ugen0.2: at usbus0 umodem0: on usbus0 umodem0: data interface 1, has no CM over data, has no break and I cannot communicate with it. Any ideas how to communicate with it? This is the output of 'usbconfig -d ugen0.2 dump_curr_config_desc': ugen0.2: at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (0mA) Configuration index 0 bLength = 0x0009 bDescriptorType = 0x0002 wTotalLength = 0x0043 bNumInterfaces = 0x0002 bConfigurationValue = 0x0001 iConfiguration = 0x0000 bmAttributes = 0x00c0 bMaxPower = 0x0000 Interface 0 bLength = 0x0009 bDescriptorType = 0x0004 bInterfaceNumber = 0x0000 bAlternateSetting = 0x0000 bNumEndpoints = 0x0001 bInterfaceClass = 0x0002 bInterfaceSubClass = 0x0002 bInterfaceProtocol = 0x0001 iInterface = 0x0000 Additional Descriptor bLength = 0x05 bDescriptorType = 0x24 bDescriptorSubType = 0x00 RAW dump: 0x00 | 0x05, 0x24, 0x00, 0x10, 0x01 Additional Descriptor bLength = 0x04 bDescriptorType = 0x24 bDescriptorSubType = 0x02 RAW dump: 0x00 | 0x04, 0x24, 0x02, 0x02 Additional Descriptor bLength = 0x05 bDescriptorType = 0x24 bDescriptorSubType = 0x06 RAW dump: 0x00 | 0x05, 0x24, 0x06, 0x00, 0x01 Additional Descriptor bLength = 0x05 bDescriptorType = 0x24 bDescriptorSubType = 0x01 RAW dump: 0x00 | 0x05, 0x24, 0x01, 0x00, 0x01 Endpoint 0 bLength = 0x0007 bDescriptorType = 0x0005 bEndpointAddress = 0x0081 bmAttributes = 0x0003 wMaxPacketSize = 0x0008 bInterval = 0x00fa bRefresh = 0x0000 bSynchAddress = 0x0000 Interface 1 bLength = 0x0009 bDescriptorType = 0x0004 bInterfaceNumber = 0x0001 bAlternateSetting = 0x0000 bNumEndpoints = 0x0002 bInterfaceClass = 0x000a bInterfaceSubClass = 0x0000 bInterfaceProtocol = 0x0000 iInterface = 0x0000 Endpoint 0 bLength = 0x0007 bDescriptorType = 0x0005 bEndpointAddress = 0x0002 bmAttributes = 0x0002 wMaxPacketSize = 0x0040 bInterval = 0x0001 bRefresh = 0x0000 bSynchAddress = 0x0000 Endpoint 1 bLength = 0x0007 bDescriptorType = 0x0005 bEndpointAddress = 0x0082 bmAttributes = 0x0002 wMaxPacketSize = 0x0040 bInterval = 0x0001 bRefresh = 0x0000 bSynchAddress = 0x0000 Ian -- Ian Freislich
