looks like i have successfully turned #GlasgowInterfaceExplorer (as well as an RTL8211FD devboard I got from Aliexpress) into a fairly decent network interface card :D
this applet is written idiomatically and with no modification of the core USB framework (using the abstractions every other applet is using, rather than direct access to libusb or something), in a single-threaded CPython 3.12 asyncio event loop
