Public bug reported: I've suffered months of bluetooth issues with my USB BT500 adapter (TPLink and Asus) in conjunction with my Logitech ERgo 860 keyboard. Input lag, disconnects, de-pairing, and sticky key like effects (press k once and get kkkkkkkkkkkkkkkkk). I switched USB ports, changed between two adpaters, added an extension cable so the dongle was right next to the keyboard, and replaced the keyboards batteries.
I tried "solution" I could find online. I finally found a repository with older firmware which seems to have fixed the issue. Older firmware is found here. https://github.com/liberodark/rtl8761b [ 2213.516670] Bluetooth: hci1: ACL packet for unknown connection handle 3837 errors have stopped and my keyboard has remained paired and I've experienced zero performance issues.
