Display never found on Lion 1.7.3

[schabbelfarfar]

Hello,

I just bought USB 2.0 to HDMI adapter to use with a Dell U2410 24" (1920X1200). I first installed the latest driver from DisplayLink 1.8a1. When I first plugged the adapter in, I never got any reaction. After that I have tried (after searching here and on the web);

- installing the other drivers
- connecting in different orders
- starting in safe mode
- tried different displays
- resetting the PRAM and NVRAM
- repairing permissions

Nothing seem to work and when I tried the adapter with a PC it worked fine. I have run the diagnostic tool you recommended and the file is attached here. This is what I ca read from the system messages:

2012-03-15 08:36:20,000 kernel: 0 0 AppleUSBCDC: start - initDevice failed
2012-03-15 08:36:21,000 kernel: USBF: 74.378 [0xffffff801649bc00] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 4 of Hub at 0xfd120000)
2012-03-15 08:36:21,000 kernel: USBF: 75.123 [0xffffff801649bc00] The IOUSBFamily has successfully enumerated the device.
2012-03-15 08:36:21,000 kernel: 0 0 AppleUSBCDC: start - initDevice failed

I also use WMWare Fusion and windows 7 64 bit and the adapter is found there but I don't get it to function properly. I guess it's because it's a virtual environment!?

I have a late 2011 macbook pro 15" with 8GB Ram and a Samsung SSD. The adapter seem to be found by OSx and appear as "WS Tech USB TO HDMI" under "system information".

Have anyone experienced problems like this or have a clue of where to begin?

All the best
