Moxa USB Console on Linux

moxa-usb-console.md

Moxa's ethernet switches come with a USB console that is not recognized by the Linux kernel. Moxa have drivers available for download on their website, but only for Windows.

The device shows up in lsusb as:

Bus X Device Y: ID 110a:3001 Moxa Technologies Co., Ltd. 

This is just a Texas Instruments TUSB3410 with a custom firmware though, and fortunately it will work with the standard firmware.

To enable it, make sure that the module is loaded:

/ # modprobe ti_usb_3410_5052

Add the custom VID/PID to the driver:

/ # echo 110a 3001 >/sys/bus/usb-serial/drivers/ti_usb_3410_5052_1/new_id

Finally, symlink the standard firmware to the name the Linux expects:

/ # cd /lib/firmware/moxa
/lib/firmware/moxa # ln -s ../ti_3410.fw moxa-3001.fw

You can now plug in the USB cable and a new usb-serial device will be added to your system.

Thanks, i have missed this and had no time for a research.

Thanks for your research!

I followed your guide and got the following:

[453678.805630] usb 2-1.7: new full-speed USB device number 7 using ehci-pci
[453678.950605] usb 2-1.7: New USB device found, idVendor=110a, idProduct=3001
[453678.950609] usb 2-1.7: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[453678.950611] usb 2-1.7: Manufacturer: Moxa Inc.̖Moxa USB Console
[453678.951922] ti_usb_3410_5052 2-1.7:1.0: TI USB 3410 1 port adapter converter detected
[453679.984872] usb 2-1.7: ti_download_firmware - error downloading firmware, -110
[453679.986217] ti_usb_3410_5052: probe of 2-1.7:1.0 failed with error -110

Do you happen to know how to fix this, or does this mean the firmware of the Moxa Switch is incompatible?

You are a lifesaver! Thanks!

Correction for working in 2024:
ln -s ../ti_3410.fw.zst moxa-3001.fw.zst
as the fw files all now are compressed and have the .zst appended.
This saved us from bricking our little moxa. Thanks!
