[lcd4linux] Connecting a new IPS LCD

[Texas E. <tex...@ou...>]

I just got myself a new 5" IPS LCD that has a USB connection.  I am able to use the provided software to pull data from windows, but I am having frustration with using it in Linux.

When I plug it into a Ubuntu system, lsusb identifies it as:

        Bus 001Device 002: ID 1a86:8040 QinHeng Electronics USB CDC-Serial

I have tried using the dpf driver, but I am unable to even get lcd4linux to even recognize the device. I have tried:

        Port 'USB:1a86/8040'
        Port '`/dev/bus/usb/001/002`'
        Port 'usb0'  through  'usb5'

Always the same result...  spf_ax_open: no matching USB device '<port>' found!

Additional details:

  *
It's a generic $30 5" lcd from aliexpress that says it will work with lcd4linux as DPF
  *
The windows version of the software identified this lcd as 'CSM050H800480_ 14 NAND'
  *
The windows software has a rudemenatary, albeit function, GUI designer.  Not sure yet how to either over-ride it or integrate with it... that will be next, after I can get Linux to see it.

Any suggestions on how to find the right port?

Thanks!!!
