After I had with another review found the correct driver, the adapter ran on smoothly. This was the version "C1" (can be found on one of the labels) and the drivers on the included CD was for version "A" ... Probably the manufacturer had ordered too many drivers CD's and wanted only evacuate his camp - no matter how many revisions it brings out in the meantime. You can find the drivers here: ftp://ftp.dlink.de/dub/dub-e100/driver_software So just do not use the drivers CD !!! After that, the computer makes only "beep beep beep" if you reinsteckt the USB connector!
