IOGear stops working iMac 10.7.3

[jasongt]

I have a late 2009 iMac 12GB ram running 10.7.3 and have 2 monitors hooked to it one using mini displayport and the other an IOGear external DVI GUC2020DW6 running the 1.8 alpha drivers and have been using this since for a couple of years usually with a good experience. I do have a problem that is sparatic that it just stops working usually after sleeping or something and the fix has been to either unplug the usb cable wait 5 or 6 seconds and plug it back up or to power off wait 5 or 6 seconds and power on. The device is present in the USB tree when this happens and once I replaced the cable that came with it with a little better USB cable that's only about 1' long the problem started happening a lot less. Is there someway to have a script or something to restart the services or whatever so that I can run it before having to power off or mess with unplugging it? (It's called being lazy I know.)

One a different topic do you think color calibration will ever work?

Are there any firmware updates for the device? I think mine is at v1.2.


Thanks

Sorry for the late answer.
What happen if you kill the DisplayLinkManager process, when the DisplayLink screen appears to be stopped?
Try this in a Terminal:
sudo killall DisplayLinkManager

Thanks
