Sequoia Problem: Logitech wireless keyboard and mouse via KVM not working M1 Mac Mini

Here's my setup:

M1 Mac Mini

TESmart Dual Monitor KVM

Logitech Keyboard: Ergo K860, Logitech Mouse: M525

-- Both connected using Logitech Receiver in the KVM

I have been using this setup for years, with the Logitech USB receiver plugged into the keyboard/mouse port of the KVM switch. Works great switching between my MacBook Pro and my M1 Mac Mini.

Yesterday, I installed Sequoia on my Mini, and now when I switch back to the M1, the keyboard/mouse are unrecognized and I cannot access the Mini.

A couple of times a forced hard reboot of the Mini (via the power switch) will get the Mini to see the keyboard/mouse, but not all the time. I'm stuck having to shutdown the Mini, detach a USB device to free up a direct port, then move the Logitech Receiver directly into the Mini, and THEN it will see the keyboard.

Bug in Sequoia?

Mac mini, macOS 15.0

You have to reach out to TESmart technical support. They have a firmware binary but they have to give it you. It's not available for public download without their assistance. Makes sense, because if someone puts the wrong firmware on the wrong device it will break the device.

Fill out the form and submit.

At the bottom of the page is their phone number in China. You could call if you had to.

Confirmed @james brickley post worked for me.

I had just upgraded to 15.1 sequoia and this issue happend to me. Before upgrading my set up was 2 MacBook Pros on Sonoma.

Then I reached out to TESmart team, and they gave me a hex file, and a .exe tool to update the kvm. They gave steps on the email, and a video demo. It was pretty easy to follow, and I was able to get it working again.

Attached is the link to download the TESmart software tool. However, for the hex file, you will need to reach out to them.

It seems we may need a new firmware from TESmart, in the meanwhile you can plugin the keyboard and mouse wireless receiver into the port at the front for the KVM switch and things will work except the hotkey switching will not. You can switch computers using the button at the front of the KVM switch.

The Tessmart fix worked for me. They sent me the firmware update tool and I followed the procedure. Not that it requires opening the unit and shorting out the chip with a precision tweezer. I used this: Amazon.com: kaverme 3PCS Precision Tweezers Set, Upgraded Anti-Static Stainless Steel of Tweezers, for Electronics, Soldering, Laboratory Work, Jewelry-Making, Model, Craft : Tools & Home Improvement

There was another thread where someone mentioned they reached out to TESmart technical support and was provided a .bin firmware update and a software tool to apply it. Then the problem was resolved.

Having the same issue with an M1 mini with no recognition of the keyboard/mouse connected to the TESmart KVM HKS0403A1U after upgrading to Sequoia. Unable to locate any .bin to upgrade KVM.

For Tesmart KVM users. Contact Tesmart support. They have the solution.

Sequoia was updated to 15.0.1 yesterday or so. Curious if the update resolves the KVM issues for anyone. I reverted back to Sonoma and I reluctant to move back to Sequoia until there's a fix.
