Issues with Dial up connection using Vodafone USB modem, Windows 10

Hi Jay,



Thank you for writing to Microsoft Community Forums.



We understand how difficult it could be. However, we would need some more information regarding the issue.

1. Do you see network signals showing as connected in the taskbar?
   
2. May I know the model of the Vodafone modem you are using?
   

Please refer to
Mobile Broadband Software for Windows 10 for the list of modem models which support Windows 10. We would suggest you to download the software utility from the article and check if it resolves the issue.



We would also suggest you to follow the steps mentioned below to check for the drivers for modem.

1. Connect the USB modem.
   
2. Open Device Manager by searching for it in search bar.
   
3. Locate and expand Universal serial bus Controllers in the list.
   
4. Check if the driver are displayed under the tree.
   

Regards,

 

Windows 10 Bluescreen WDF_VIOLATION if USB device used USBSER.SYS and add to a Modem

We can always reproduce a bluescreen on Windows 10, if a USB device which used the USBSER.SYS driver is attached to a Windows Standard modem.



Environment:

• Windows 10 Pro, Final Build 10240, 64 Bit

Steps how to reproduce:

• Connect a USB device which used the USBSER.SYS driver
• Windows Device Manager displays the device in section "Ports (COM & LPT)"
  
  For example "Serial USB Device (COM3)"
  
  This is OK
• Start the "Phone and Modem" application
• Select the "Modems" tab and select "Add..." to "Install New Modem"
• Select "Don't detect my modem, I will select it from a list"
• Select "(Standard Modem Types)" and e.g. Model "Communication cable between two computers"
• Select the serial port which is used by the connected USB device (e.g. COM3 for this example)
• Windows starts installing the Modem... but...
• Bluescreen with information about an Error: WDF_VIOLATION
  

Notes:

• This error does not occur with USBSER.SYS driver on Windows XP, 7, 8
• I know that the USBSER.SYS driver is rewritten for Windows 10
  
  Perhaps this specific use case with the Modem assignment was not tested with this new driver?
• This bluescreen is reproducible with different connected USB devices which used the USBSER.SYS, e.g.:
  • embedded device with USB Stack from eCosCentric
  • embedded device with USB Stack from STMicroelectronics

Thanks for any help and support
