MBP 15" i7 OS X 10.6.7 DisplayLink 1.6b3 DL-195- clam shell not working

Hello everyone, I need some assistance

Here is my setup:
Macbook Pro 15" i7 (early 2011 w/ Thunderbolt) running OS X 10.6.7
DisplayLink 1.6b3
Plugable 10 port USB 2.0 Hub (w/ power supply)
Two (2) Plugable UGA-2K-A (DL-195)
Two (2) Dell P2210 LCD monitors

MBP and Plugable UGA-2K-As connect to Plugable USB Hub, each Plugable UGA-2K-A connect to monitors via DVI.

Problem
I can't get my MBP to work in "clam shell" mode. As soon as I close the MBP lid, the LCD monitors go blank and my MBP goes to sleep. I tried restarting the MBP and closing the lid as soon as it booted but the monitors were just blank. If I open the MBP lid, the monitors work fine.
I have the same exact issue with the UGA-2K-As plugged directly into my MBP (no USB hub).

Am I doing something wrong or is there an issue with running in "clam shell" mode? Thanks in advance.
