DisplayLink overloads Windows Kernel

[JH_MMC]

Dear Community, we're developing a product working under DisplayLink with this 10" USB LCD (http://lilliputdirect.com/lilliput-um1010-touchscreen).

We're detecting some troubles with the Windows 7 PosReady and the Windows Kernel due this is overloaded for the DisplayLink driver.

Our scenario is:
- Win 7 PosReady x32bits
- The USB 10" display by USB 2.0 connection. Driver DisplayLink_7.6M1
- No peripherals (the display is for Maintenance of the system)

We see the next analyzing the system kernel consumption:

In Windows 7 32-bit kernel stack apparently are 12 Kbytes.
What is the Kernel stack size of the displayLink software? It is a "normal" environment this memory?

Any knows any recommendation to (something that is available to disable) release the kernel load.

Many thanks in advance!
Regards
