Wireless Ralink Adapter is detected but doesn't work

[Nikolay Tychina]

Hi!

I got TP-LINK TL-W727N adapter with a Ralink chipset, added

    product RALINK RT5370           0x5370  RT5370 // to usbdevs
    RUN_DEV(RALINK,             RT5370), // to if_run.c
Re-built module, run0 interface then appeared in ifconfig. But if I do
"ifconfig wlan0 up", the command just hangs,
there appear lines in dmesg:
run0: firmware RT3071 ver. 0.236 loaded
run0: at uhub3, port 5, addr 4 (disconnected)
usbd_req_re_enumerate: addr=4, set address failed! (USB_ERR_STALLED,
ignored)
usbd_req_re_enumerate: addr=4, set address failed! (USB_ERR_STALLED,
ignored)
ugen1.4: <TPlink> at usbus1 (disconnected)

Any way to get it working?
