There is a known problem with the dynamic power management code for this

Did my email to the list yesterday provide any further clues at all? I know that
you're looking at re-working the power code, but if there is any chance of a
stop-gap fix for 3.12 then I know it would be greatly appreciated :)
Yes, you provided some clues, but as I have no knowledge of the internal
workings of the chips, I dare not set parameters willy-nilly as that might cause
chips to burn out and fail.
The vendor driver provides better performance for my device than does rtl8192cu.
I would provide the patches needed to compile it on a modern kernel; however, it
causes a kernel panic whenever you try to unload it. I have no time nor
inclination to debug that. Thus no one should use it unless you want to fix that
problem.
I am trying to change the in-kernel dm code to match the vendor driver. That is
difficult as nearly every variable is renamed.
Any patches will be pushed when they are ready, and not before. I will, however,
provide them for testing. It remains to be seen if any such patches will be
suitable for 3.12 and backporting to 3.11.
