Ha!  And some day I'll get around to buying a couple TP-Link TL-WN722N and 
stop having to muck around with this stuff!

Done.  Well, that got rid of the alloc errors. Still get the unknown device 
in dmesg, but apparently that is to be expected as other devices that load 
correctly seem to exhibit the same unknown device message.

Now onwards through the fog...

I have the following in /etc/network/interfaces (sans actual AP ssid and 
credentials) which worked just fine with 3.8:

auto wlan0
iface wlan0 inet dhcp
    wpa-ssid "xxxx"
    wpa-psk "yyyy"

# Logic Supply UWN-200 (RaLink)
auto ra0
iface ra0 inet dhcp
    wpa-ssid "xxxx"
    wpa-psk "yyyy"

I now need to manually enable the link (ifup ra0) to get the interface to 
come up.  Shouldn't these interfaces come up at boot time due to the "auto" 
stanza?  They did in 3.8.  Has something changed in 3.14 that prevents the 
interface from coming up automagically at boot time?  I have the same 
problem with another USB dongle, I need to manually enable the link (ifup 
wlan0).

And of course...when I unplugged the 2 dongles (that were both up), 
everything froze (no panic, no nice blue led's flashing, just the power led 
on).  I think its the Realtec dongle that was on wlan0.  Rebooted, with 
just the Realtec dongle, can plug and unplug it with no problems.  But if I 
enable the link (ifup wlan0), then unplug it, boom.  Doing the same with 
the UWN-200 RaLink dongle doesn't seem to cause the same crash/hang.

Note that neither the UWN-200 nor the Realtec devices are successfully 
associating with the AP configured in /etc/network/interfaces.  They 
associate just fine in 3.8 with the same /etc/network/interfaces.

Geez, back to WiFi dongle hell...
