Greetings, I am trying to connect an MC7430 to my new windows 11 laptop so I can configure it with AT commands using PuTTY. I have installed the generic driver package from the MC7430 support page but the device is not recognized in windows device manager at all. I am using a USB to PCIe adaptor and it works perfectly on older machines running windows 7, 10 and everything works fine. so i can only suspect the driver is not compatible. Can anyone help please? ---

I don’t see problem in Win11. I used this driver: > [@USSD Software for Windows 10](https://forum.sierrawireless.com/t/ussd-software-for-windows-10/25041/26): > > I don’t see there is modem port enumerated in your module, try this: download the GenericDriverSetup\_5087.exe from SOURCE website open a folder and put GenericDriverSetup\_5087.exe and Configuration.ini together open Configuration.ini and add the following: [Default Values] CHECKFORDEVICE=0 LOCATIONDRIVER=1 WIN8LOCATION=1 USBCOMP=99 now install the driver again Or you can see more information here: In the configuration.ini file, i have set USBCOMP=8 ---

thanks you very much… I have created a new folder on my desktop and added the genericDriverSetup\_587.exe and the Configuration.ini file and reinstalled the drivers. still nothing shows in device manager and there is nothing recognised on the USB port… (i.e. no usb sound) ---

is the USB port OK? Do you have Vmware of Linux installed in this Windows 11? This can verify if the hardware of USB is OK. ---

yes the USB port is OK. It is a brand new Dell laptop and every other USB device is recognised correctly. I do not have Linux installed but the hardware is ok and all of the windows and dell diagnostics show it to be OK. ---
