r/networking on Reddit: USB-to-Serial for console that works with Windows 11?
July 9, 2024 -

Need some recommendations from fellow Network Engineers who have already dealt with this. Our org recently updated to Windows 11 and it killed our ability to use our USB to Serial adapters because of Windows core isolation/memory integrity settings. Our domain admins have given up trying to disable memory integrity for us so now it's on me to figure out a viable alternative for our console connections, and I really don't feel like rolling the dice on random purchases.

Anyone have a recommendation for a USB-to-Serial adapter that will work when Windows 11 Core Isolation security settings are all turned on? It really needs to be a legit serial connection on the adapter too because most of our network infrastructure doesn't have native USB console ports and also we are doing Serial over Ethernet in a few places and those require native serial on both sides.

Thanks in advance :)

December 21, 2022 - @Maty Blanc This seems to be a Windows 11 problem with newer drivers. As I am sure you have discovered, the primary suggestion is to completely uninstall/remove the driver through Device Manager and then to install an older revision of the driver after unplugging the device.

This is not unheard of. Windows 10 and 11 tend to auto-install the latest drivers for things, including the drivers for the USB-Serial cable. The workaround is to install an older version of the driver.
