USB connection problem

Any idea why my M1 MacBook Air frequently loses connection to my vintage USB (Kensington Expert Mouse Pro) trackball, plugged in via Apple’s a1621 HDMI-to-USB C adapter? (I’ve learned that these adapters can be fussy, and flipping the USB-C connector 180º is sometimes important for reasons that elude me, but that seems not to be the issue here.)

To clarify, is the MBA sleeping when the mouse gets disconnected?

Not sure about an M1 Mac but older Macs sometimes needed an SMC reset if they developed USB-related issues. It just involves holding several keys while booting up (search Apple Support for SMC reset). It won’t harm any data.

Thanks. But apparently M1s don’t have an SMC reset option.
