I do not maintain these drivers, but as no one else has answered, I will offer
some suggestions.
First of all, it would be helpful if you posted the USB ID as shown by lsusb. As
the kernel loaded the module, it must be one in the tables, but that info is
usually needed.
The second thing to verify is that your configuration contains the line
"CONFIG_RT2800USB_RT53XX=y". This parameter is marked as depending on
EXPERIMENTAL, and I'm not sure that Ubuntu enables those parameters in their
kernels. Again as the module was loaded, I think your kernel is OK, but that
parameter is something to check.
Finally, if your kernel configuration is OK, you will probably need to bisect
the problem between v3.18 and v3.16. I have a device that uses rt2800usb, but it
is not a 53XX. FWIW, it works.
