USB-> 3-4x LD220 in chain, during first init hang.
Attempt to init 2 Screens, then connect 3rd - Laptop LCD became black,
Windows 7 keyboard hang.

Windows XP, init working ok, in any configuration.
Linux - also.
Ready to provide any additional details for problem debugging,
right now under Windows 7 my configuration with 4x LD220 are unusable, work only 2 screens.

Please post your log files for Windows 7 to show the issue with more than 2 displays.

Thanks
