Good morning,
I am now running Zorin 17.2 Core for about half a year now. Of course there is still a lot to learn but I am improving bit by bit. My system is still a dual boot Windows 10 / Zorin 17.2 system which mostly I run in Linux mode.
There is however one program which works fine under Windows and so far I have not got it to work in Linux. It is a slightly outdated Windows program which communicates with an external device on a Windows COM port at 19200 baud.
Within Windows a USB to serial driver is installed which let this program use a USB cable to communicate with the device.
When plugged in and running Zorin, I have found the device when running lsusb in the terminal:
Bus 002 Device 002: ID 8087:8000 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:8008 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 003 Device 003: ID 056a:00b7 Wacom Co., Ltd PTZ-431W [Intuos3 (4x6)]
Bus 003 Device 002: ID 0461:0010 Primax Electronics, Ltd HP PR1101U / Primax PMX-KPR1101U Keyboard
Bus 003 Device 011: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
It is the future Technology Devices International on Bus 003 Device 11. This device number increases each time I unplug and plug the device in again.
I have tried adding a COM3 entry in HKEY_LOCAL_MACHINE\Software\Wine\Ports with value /dev/ttyUSB0 using the wine regedit program. As a Windows user since 3.11 I am quite familiar with the windows registry.
This had no effect however.
I also installed minicom and set the ttyUSB0 as a serial device with 19200 baudrate but this did not help either.
There is a lot of communication about wine com ports and Linux which is quite overwhelming and most are still above my experience level in Linux.
It comes down to the following questions:
- Do I use regedit or a symbolic link to connect COM3 (or any other port) to /dev/ttyUSB0 and is this indeed the right device name? It does not make sense from my lsusb output above.
- How can I set the UART settings for this COM port as the hardware device expects 19200 baud?
As all works well in Windows 10, I can rule out any USB cable issues.
Any help is greatly appreciated!
