If you did so rollback the position by System Restore and try again. this time put the usb cable only when the rconnect installation says so. 3. If nothing works out , might be the driver is mismatched (in grey market cables) even you got the driver cd. you can check it easily by yourself and can fix it (by editing the driver .inf file) very easy Please download ftdi usb viewer from web site usbviewftdi.zip You can also view in the properties page of the unknown device of device manager note down pid and vid open the driver .inf file and look if the file have the same entry i.e pid and vid vid is standard Vendor ID pid is product id of that vendor if those entry doent match it means the driver you have got is not right. either serach for the right driver or can try to edit the .inf file change the entry of pid and vid to the entry u found in device manager usb cable (unknown) property akash Share this post Link to post Share on other sites
