How often Microsoft update Xbox one controller Firmware ? I update to 4.8.1923.0 and it’s...

"I have updated the firmware on both controllers. Current firmware version is 2.3.2381.0."

I would check your firmware version because the version I have is a lot higher than the one you have, 4.8.1923.0.. Update
XBox one controller with the uSB method.

"This just says firmware update, which I can;t select"

Do you mean it is up to date with Version 4.8.1923.0 and it reports no update found or is it greyed out and you can't select it at all?

This link, Update wireless controller will guide you through the steps if an update is required.

What kind of Xbox One controller do you have?

From going to All Settings-->Kinect & Devices-->Devices & Accessories-->Xbox One Wireless Controller, the latest firmware shown on my controller is "2.3.2385.0". Checking for updates yields no results, and says that my controller is on the latest firmware.

This controller of mine is a standard black controller (with the 3.5mm port) that I purchased as a separate accessory. I think only the Elite controller has a different firmware due to the extra functionality.

If there's no update available, then you're already on the latest firmware! Microsoft doesn't really push out controller updates very often.

i hope this help you

"So yesterday I found a USB cord, plugged the controllers (one by one) to the console, and successfully updated their software (firmware? whatever) from v1.1.400 to v2.3.238


"discovering that controllers have their own update-able software (jeezas, whyyy?) and understanding that I have never updated seemed like the perfect fit for a reason of failure"

"Finally, another argument in favor of the controllers being fine is that those work like a charm (i.e., we haven't seen them shutting down yet) when connected with the USB wire."

Curious that the OS version build your console has installed, the latest,
as my controller firmware version is 4.8.1923.0. ... and always connected via uSB.

Depending on how you let your console do system updates, automatically (Instant on) or manually, as I do, you may not have seen a notification to update the controller firmware.

I had at least 2-3 banners pop up immediately after a System updates, but that was a few months ago, and many updates since.
