Compatibility: Windows, Chrome OS (USB port required), plug‑and‑play with no drivers needed for basic usage

Troubleshooting feedback: Some older K520 units may lag or freeze under heavy use, especially when paired via a newer Unifying receiver; cleaning or avoiding USB3 front ports may reduce interference Receiver note: Requires an official Logitech Unifying receiver (with the orange star logo) to pair; any compatible unifying dongle will work if it supports pairing software

🔄 Common Features & Combo Notes
Both devices work with a single Unifying USB nano‑receiver, so only one dongle is needed for both keyboard and mouse connection

Setup is plug‑and‑play: insert the dongle into a USB port, switch on devices, and they pair automatically.

For device customization (programming buttons, macros), Logi Options (or Options+) or SetPoint may be used depending on hardware firmware
