Just tested it and it passes the rt2x00lib_load_firmware but still errors on rt2800usb_set_device_state:

[  348.363942] ieee80211 phy1: rt2x00lib_request_firmware: Info - Loading firmware file 'rt2870.bin'
[  348.364519] ieee80211 phy1: rt2x00lib_request_firmware: Info - Firmware detected - version: 0.36

which was the last error i got in my previous dump_stack too (which you linked):
