The connection between my K380 keyboard and the USB-BT4LE adapter. It was working fine on Windows 10 1919 (OS Build 18363.1139), but upgrading to Windows 10 2004 (OS Build 19041.572) broke it. In both instances I was using the Broadcom BCM20702 driver (version 18.104.22.1680), but the newest version of Windows removes my ability to change the power management options (apparently as part of the new “Modern Standby” feature). When I was able to turn off the “Allow the computer to turn off this device to save power” option, everything worked.
Is there a solution to this problem?
Properties before the update (1909). The whole “Power Management” tab is gone in 2004.
