I conducted some initial tests, and everything appears to be working as expected. I will attempt to console into a device later to confirm functionality, but here are the steps I followed:
1. Installing USB to Serial Drivers
First, I installed the necessary USB to Serial drivers by running:
opkg update
opkg install kmod-usb-serial kmod-usb-serial-pl2303 kmod-usb-serial-ftdi kmod-usb-serial-cp210x
2. Connecting and Verifying the USB to Serial Adapter
After plugging in my USB to Serial adapter, I checked if it was recognized by the system using:
dmesg | grep -i usb
3. Installing Picocom for Serial Console Access
Next, I installed Picocom, as it is a lightweight alternative to tools like screen or minicom:
opkg update
opkg install picocom
I will update this post once I have tested the connection to a device via the serial console.
Let me know if you have any suggestions or if you've had similar experiences with USB to Serial adapters on OpenWRT.
