USB-CAN Analyzer Linux Support
These adapters can be found everywhere on Ebay nowadays, but there is no official Linux support. Only a Windows binary file stored directly on GitHub.
When plugged in, it will show something like this:
Bus 002 Device 006: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
And the whole thing is actually a USB to serial converter, for which Linux will provide the 'ch341-uart' driver and create a new /dev/ttyUSB device. So this program simply implements part of that serial protocol.
