Installing USB serial modules on NAS Synology DS212+

Currently running a NAS Synology DS212+, DSM 4.0-2228

2 needed modules:
- ftdi_sio.ko
- usbserial.ko

insmod on each.

Possibly needed, create device node:

mknod /dev/usb/ttyUSB0 c 188 0
stty -F /dev/usb/ttyUSB0 1200 sane evenp parenb cs7 -crtscts

Plugging USB-Serial converted should show something like this on dmesg:

[1124863.890000] usbcore: registered new interface driver usbserial_generic
[1124863.900000] usbserial: USB Serial Driver core
[1124867.710000] USB Serial support registered for FTDI USB Serial Device

    Im trying to install a RFXtrx on the synology, but im a novice in these type of things. Could you explain step by step what to do with the 2 modules explained in the beginning of your post?

    Best Regards

      Hi,

      insmod path/to/module.ko

      will simply load module into the kernel. lsmod will show it listed if properly loaded. You would need to copy ko module file to /lib/modules//some/sub/dir in order to put it in “official” path. You’ll then be able to load it automatically at boot for instance. When properly installed, you can use:

      modprobe module

      (without .ko extension). modprobe will scan /lib/modules/… looking for your module.ko file.

      Hey, RFXtrx looks nice ! Good luck.

    Hi, I also tried to get RFXtrx working on my DS212 and followed the tutorial above but still can’t get it working.

    insmod usbserial.kp
    insmod ftdi_sio.ko
    mknod /dev/usb/ttyUSB0 c 188 0

    after doin this I can’t find the device with dmesg

    Is it possible to make step by step guide for dummies like me?
