      Hmm, ok. Those serial devices are just the seemingly omnipresent com1 and com2.
      Any of those disappear when you unplug it?

      Clearly your screen is being recognised and attached to the uslcom(4) driver.

      Steve

      Edit: Try looking in /dev/usb

      Edit2: I see that your display is 'edition 3' and there is a driver option for that:
      http://lcdproc.sourceforge.net/docs/current-user.html#SureElec

      Edit3: Your device is on usbus1 so try ugen1.1      <– try this first! Hmm unsure about this now. It should definitely appear as ugen1.x though as it's on usbus1. ugen1.1 is probably the hub though.

        There is no ugen0.2 when i unplugged the LCD but i am still getting same error:

        LCDd: Driver [SureElec] init failed, return code -1

        I have tried /dev/usb/0.2.0 and /dev/usb/0.2.1 but same got this error:

        LCDd: SureElec: failed to configure port (Inappropriate ioctl for device)

          Ok so assume ugen0.2, have you tried 'edition=3'?

              Reading through the source code for the Sure Elec driver it expects to see a serial port not a usb device.

              Surprising that the uslcom driver does not generate a new serial device.  ???

              You should ask in the lcdproc-dev package thread. The new maintainer, mdima, is using a SureElec LCD.

                It looks like the device should appear as ucom0.
                You need to have the ucom(4) driver loaded. Is it in the kernel?
                The uslcom driver has been updated quite a bit since 8.1 was released, though it seems to recognise your device.

                You could try adding the ucom driver from here:
                http://files.pfsense.org/jimp/ko-8.1/i386/ucom.ko
                Add it to /boot/modules.
                Load it from the command line:

                kld_load ucom.ko

                Or add ucom_load="YES" to /boot/loader.conf.local and reboot.

                    Yes you can upload it. I usually use WinSCP uploading from windows.
                    Alternatively you can fetch it directly from the machine:

                    
[2.0.1-RELEASE][root@pfsense.fire.box]/root(1): cd /boot/modules
[2.0.1-RELEASE][root@pfsense.fire.box]/boot/modules(2): /etc/rc.conf_mount_rw
[2.0.1-RELEASE][root@pfsense.fire.box]/boot/modules(3): fetch http://files.pfsense.org/jimp/ko-8.1/i386/ucom.ko
ucom.ko                                       100% of   20 kB  429 kBps
[2.0.1-RELEASE][root@pfsense.fire.box]/boot/modules(4): kldload ucom
kldload: can't load ucom: File exists
[2.0.1-RELEASE][root@pfsense.fire.box]/boot/modules(5): /etc/rc.conf_mount_ro

                    However as you can see on my machine ucom is already present in the kernel.

                    The only other thing is to check that the USB product and vendor IDs are in the source code correctly.
                    Enter: usbconfig dump_device_desc
                    Paste the output here.

                      NOTE: This LCD works properly under FreeBSD 9-STABLE but not under pfSense 2.0.1-RELEASE (i386)

                        In that case it's almost certainly due to the usb ids not in the source.
                        Have you tried one of the pfSense 2.1 snapshots? Based on FreeBSD 8.3.

                        Under FreeBSD 9 does it generate a new serial port?

                        Looking at the 8.1 source it is in the usbdevs file.
                        The ucom functionality has been changed from 8.2 up so it's hard to see how to update.

                          It generates ugen1.2

                          I will try 2.1 tonight and will let you know asap.

                              Well 2.1 is a work in progress so some things may not work. I take it LCDd won't start then? The lcdproc-dev package won't work because it's compiled for 8.1 you have to use the FreeBSD pkg.

                                Yeap. i just re-installed 2.0.1 and finding new LCD that compatible with my Alix board and pfSense 2.0.1. Do you have any recommendation?

                                Thanks.

                                  All my experience is with the Firebox LCD which is built into the appliance so not much use to you.
                                  Probably best to ask in the lcdproc-dev thread. Although I note that the only reference to the LCD you have is in reply to a similar suggestion.  ::)
