[PATCH] Add support for USB-WiFI Mercusys MW150US

["Vladimir 'phcoder' Serbinenko" <phcoder%gmail.com@localhost>]

It turns out to be a rebadging of a supported device. Simple addition to detection table is enough to make it work. It's broken down in 3 patches:

1. Adding to usbdevs

2. Running Makefile -f Makefile.usbdevs

3. Adding to detection tables

Since patch 2 is large and is pure regeneration I don't send it here but can do so upon request.
