Ralink RT5370: драйвер для оптимальной работы сетевого интерфейса

For the reference of anyone trying to solve the same problem, the correct answer was to ignore the vendor's supplied device driver and use the precompiled Debian rt2800usb driver instead - just apt-get install firmware-ralink; sudo modprobe rt2800usb;. Apparently Ralink's driver has needed patching to get it to compile since Ubuntu 12-ish.
