Steam Deck Controller ID Lacks Any Letter Code

I have an LCD model Steam Deck with the only modification done being an SSD upgrade inside. My left stick's rubber ring up top has gotten loose so I'm debating ordering a replacement from here, but hit a snag. Upon checking the Steam Deck Controller ID on my deck, I don't have a proper ID that matches what I've seen online; rather, it simply reads '12345678' with no sort of letter code at all. Is there some way to fix this within Steam itself? Is there something on the stick module inside that also marks whether its a Type A or B on the board?

I have the same issue on my Steam Deck. It started after a system update.
After restoring from the recovery image, the identifier is displayed correctly again, but once the automatic update installs, it changes back to 12345678.
I searched for information about this problem but couldn’t find anything useful.
For identification purposes, you can check it using:

cat /proc/bus/input/devices

Thank you for the comment. I input the line into the Konsole and found results for two different Steam Controllers (but I'm assuming both are the same), and I'm guessing the 'Uniq' line refers to the ID? If so, I'm more puzzled as both read out as '123456789ABCDEF', which while more descriptive, still doesn't match what iFixit has on their site.

Hello friend!

I had to register because I'm having the same problem and haven't been able to find a way to fix it yet.

About two days ago, I had to reinstall SteamOS on my Deck OLED, and after that, the controller ID number no longer appears.

The joysticks are working correctly, the serial number of my SteamDeck is being displayed correctly, but the Steam Deck controller ID only appears as 12345678.

Earlier, I opened a support ticket with Valve to check with them if there's anything that can be done.

The biggest problem is that it's not possible to redeem the rewards earned when purchasing the device (since it's tied to the device's serial number).

If I have any news, I'll come back here and let you know.
