Public bug reported: I'm using a MessPC Environment Sensor which connects via USB emulating a serial device. The sensor data is sent as text to the serial port.
lsusb reports the device as Bus 005 Device 003: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC On karmic the usbserial and ftdi_sio seem to load without problems, but I cannot read any input from the serial port. dmesg output when connecting: [ 638.040267] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0 [ 638.040285] ftdi_sio 5-1:1.0: device disconnected [ 642.610015] usb 5-1: new full speed USB device using uhci_hcd and address 3 [ 642.813044] usb 5-1: configuration #1 chosen from 1 choice [ 642.819979] ftdi_sio 5-1:1.0: FTDI USB Serial Device converter detected [ 642.820010] usb 5-1: Detected FT232RL [ 642.820014] usb 5-1: Number of endpoints 2 [ 642.820021] usb 5-1: Endpoint 1 MaxPacketSize 64 [ 642.820023] usb 5-1: Endpoint 2 MaxPacketSize 64 [ 642.820025] usb 5-1: Setting MaxPacketSize 64 [ 642.821008] usb 5-1: FTDI USB Serial Device converter now attached to ttyUSB0 I don't get any error messages. The devide /dev/ttyUSB0 can be opened and speed and other parameters can be configured. It only remains silent when trying to read the data. The devices works fine on jaunty. I only found a description of the device in German at: http://www.messpc.de/sensor_alphanumerisch.php ** Affects: linux-meta (Ubuntu) Importance: Undecided Status: New -- [karmic] usbserial regression with MessPC Environment Sensors https://bugs.launchpad.net/bugs/474180 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
