USB driver version: 220.127.116.11
Windows OS: Windows 2018 R2 64 bit
Issue: USB driver installed successfully, “Sierra Wireless AT Command Port (UMTS) (COM7)” was shown. But after 5 minutes, it changed to “Unknown Device”.
Have tried on another PC, facing the same problem
Does Sierra Wireless USB driver version 11.5 support Windows 2018 R2 64 bit?
Or this is module/terminal issue?
