after connecting the sterlingkey and navigating to the updater in Chrome, this is the complete log after trying to download the 1.0.2 firmware:

Does the device work apart from this? Is this only an issue when trying to update the firmware?

Yeah it does work, I'm using it right now. It picked up my preonic and paired successfully, and it's working great so far.

I'm glad it works!

Is it possible to try the below?

• Another usb cable
• Another port (preferably usb 3.0)
• Without the keyboard connected
• While in sleep (tap the touch sensor for 3 vibrations and it will put itself into sleep mode)
• As a last effort, another machine if possible

Ok, I can try a few more combinations - but so far I've used the cable that it shipped with and another cable that I know works, also a USB-C to A. I don't have access to a Windows computer at the moment, so I tried passing the device through to a Windows 11 VM using UTM on my mac, but it looks like it wasn't recognized by the VM - are there Windows drivers that need to be installed?

All attempts so far have been with the keyboard disconnected and in from sleep mode.

I'll do a little bit more testing, but for now everything seems to be working OK.

As an aside, can it be updated from the CLI?

I tested it on my old macbook and I actually got the same Error: Timeout result. I'll look a bit more into it.
I'm sure it's possible to upload from CLI, I'll have to write some instructions, but let me see if I can fix it first. At least it's reproducable so it's hopefully fixable.

I found the latest MAC drivers here

I'm still getting the Error: Timeout however, I'll let you know when I find something else.

Thanks for all your support!

Hello!

Could you please try again, but this time I added a dropdown for the connection speed. It seems like MacOS/ChromeOS and similar operating systems can't work with the faster speed. Choose Slow in the dropdown, click Connect, and try again.

Thank you for your patience!
