As you can see in the ralink web[1] RT28XX/RT30XX USB devices (RT2870/RT2770/RT3572/RT3070)
need _only_ the rt2870.bin fw-file.
And RT28XX/RT30XX PCI/mPCI/PCIe/CardBus devices
(RT2760/RT2790/RT2860/RT2890/RT3060/RT3062/RT3562/RT2860/RT2760/RT2890/RT2790/RT3090)
need _only_ the rt2860.bin fw-file.

That's a good joke!
linux-firmware is *unmaintained* , a lot of firmwares are missing.
Even the intel ones(microcode.dat, ipw2{1,2}*), zd1211, etc...
Others are very old, really it's a mess.
Fedora puts _forty_ patches on top of linux-firmware.
