this was tried with 3 different sim cards. I tried an external card reader connected via USB and the same negative results. Any further action from within windows does not solve the problem. When a sim card is inserted a Windows sound is heard and the 'Installing Device Driver' window shows up but then another window stating the installation was not successful. One of the slots in the reader is for sim cards.
It shows up as 4 different drives when I look at 'My Computer' and elsewhere. On my PC there is a card reader connected.
