Freezing screens using displaylink

[kingmoocow]

I'm using a Dell Inspiron 9400, with a Lenovo DVI to USB adapter from Displaylink (pn: 45k5296 -- windows shows this as M01061). Windows 7 x64.

Initially, I installed the 6.0 drivers from the DL website, and then connected the DL device, and it worked normally. After several hours, the display froze. Not the entire screen though. I can actively see the mouse pointer moving around, but none of the content on that screen is visible at all. It just goes black except for the mouse cursor.

So, I tried:
Disconnecting and reconnecting the displaylink via USB.
Disconnecting and reconnecting the monitor power and video cables.
Replacing the USB wire.
Swapping the displaylink unit for another.
Swapping USB ports.
Disabling and reenabling the device in device manager.
All yielded the exact same result - black screen with only a mouse pointer visible.

A full system reboot usually corrects the issue for a few hours, before it recurs.

I have also uninstalled 6.0 and installed 5.6M1, but the same symptom persists -- it works for a while and then freezes with no way to reenable it aside from a full system reboot.

I've attached here the diagnostics from the tool, using the 5.6m1 driver. I'll run it again with 6.0 when it manifests again.

I've run these devices on several other machines without incident, so I'd really like to find a solution for the freezing.

Thanks,
