Hi Larry, Ziv, and Georgia,
These rtl8192cu drivers seem to be very flakey / non-functional on Raspberry Pi.

Sorry, but I only support the drivers in the current Linux kernel, and as
backported with compat-drivers.

No mac80211 driver will support *ALL* of the ioctl commands. You should use iw;

There is a major bug in rtl8192cu that was just fixed this past week. See
