PicoCom4 USB Board Driver do not work with Win7 64bit

Dear All,

I did install the NetDCU USB loader V2.4.1.0 x64 onto my Win7 64bit system. Then I connect the Starter Kit with PicoCom4 Module to the PC via the USB cable.
In system tray the message appears "driver will be installed". After approximately 2minutes the message appears "driver can not be installed". In the device manager beneath USB-Controller the item FSBoardUSB Driver is marked with the yellow triangle. Do somebody knows whether there is a compatibility problem with windows 7 in general or do I need to setup with other drivers etc?

Thanks a lot in advance for help.

Hello,

concerning the kind of connection I mean 1) PC4 Bootloader EBoot -> PC.
I need that connection to update the kernel via USB connection from NetDCU USB Loader (after DU command transmitted from DcuTerm).
