My aim is to install a USB wifi module on my TK1.
I’ve recompiled the linux kernel to install and load the driver, and everything seems to work (as far as lsusb and lsmod can tell) but can’t see any wifi with iwconfig.
The old tool iwconfig, which uses Wireless Extensions interface, is deprecated and it’s strongly recommended to switch to iw. Most wifi drivers in modern kernel are based on nl80211.
Here’s documentation for iw: https://wireless.wiki.kernel.org/en/users/documentation/iw
For connecting to wifi networks, we recommend using connman.
“connmanctl technologies” returns only the wired connection
“connmanctl scan wifi” or “connmanctl enable wifi” return errors because the “method doesn’t exist”

Can you send a link or datasheet of the device you are connecting to the USB Port. It looks like the device you are connecting is just a USB to UART Converter.
