No Driver for Win7 or WinXP / URGENT

Hello,
I bought today an USB interface card VM110N. I conneced to 1 Win XP PC and to 2 Win 7 PCs. Also to different USB-Connectors on each PC.

Always the same problem: Win try to install a driver but don’t find any suitable driver.

Messages from Win: “USB-Gerät wurde nicht erkannt”, “Die Gerätetreibersoftware wurde nicht installiert.”, “Unknown Device”

I copied the dll into the right foder. The K8055N_Demo.exe can not find the card.

When I connect the card, the power led is on an the first out led flashes 3 times and after stay on.

Thank you for Help!

The driver is included in the operating system.
No need to install any driver for the VM110N.
Most probably the USB cable or the VM110N unit is defective.

There may also be some kind of conflict with other USB devices or programs or drivers.

I changed the USB-Cable and now it works! So the new cable from the card is defective.

Thank you for the very fast help!!!
