add support for the DEC3000-s (Alex Woods)
use the hotplug firmware loader for 2.6 kernels instead of compiling the
firmware into the module (Alex Woods)

Support for external USB adapters designed by Technotrend and

+ produced by Hauppauge, shipped under the brand name 'DEC2000-t'

Even if these devices have a MPEG decoder built in, they transmit
only compressed MPEG data over the USB bus, so you need
an external software decoder to watch TV on your computer.
- Say Y if you own such a device and want to use it.
+ The DEC devices require firmware in order to boot into a mode in
