You've got a at76c505a chipset, which the Berlios driver currently has no
firmware for. There is one in the SF driver, but unfortunately it's the
WPA-enabled version only, which won't work with the current Berlios
driver. I've started to look into the SF driver, but it's difficult to
understand - I need more info about WPA first (just ordered a book).
Hope in 4-6 weeks the Berlios driver will support 3eb/7614 devices
(i.e. SMC2662W rev.4 as well).

The USB ids in the device table at
http://at76c503a.berlios.de/devices.html must match your adapter, too many
manufacturer re-use the product name for a different hardware revision.
You may sometimes be able to see this on their Win driver download pages
or in the .inf file of the most recent Win driver.
