I'm not sure what I did, but after a combination of messing around with this script and another script I found on the reddit thread, I did finally managed to get this to work. It felt like I was cheating the system because of how many attempts failed but I finally got it to work once.
I opened the deck and applied an update that came out today. And now the script doesn't work again. Using my previous method of running the script twice is no longer working, either. For that matter, before the update the gadget would still persist even after restarting the system, but after the update, restarting the system now results in the gadget being deleted.
I can't help but to feel that Valve put a hard lockdown on sys in the recent update, or something. I thought I'd at least let you know, just in case the latest update did actually end up killing the script.
I believe that this issue has always been on the deck's side. There's no indication that the script was functioning, and when trying to stop it, it'd say the device (the gadget) doesn't exist, suggesting it was never created in the first place. It would be nice to get more hands on troubleshooting with this, but with the latest update, I'm unsure if there's anything that can be done about it now. Unless I'm messing something up, somehow. I did check the folders that were supposed to be created when the script is run, so the only thing I can guess is that it's actually running the gadget that isn't working, and the script has no way of showcasing it working or not.
DRD is on, and I've disabled/enabled it many times. Doing anything with the bios and messing with the USB cable make no difference. At this point even lsmod is only showing one line, instead of the many I showed before. My BIOS version is still 131. It hasn't changed with the update.

I think we need to freeze steam os version it worked.

What do you mean? How would we freeze the steam os version?

It's very likely that an update did end up killing the script, but it's not Valve putting a hard lockdown on anything. This happens every now and again because they aren't currently focused on USB DRD and the drivers sometimes stop working until they fix it. It's just a matter of time until it starts working again. It might even work on the beta right now, or stable if you're on beta. It's also possible that the script needs updating.
There's no indication that the script was functioning
I never added any, this script was mostly a proof of concept.
with the latest update, I'm unsure if there's anything that can be done about it now.
Like I said, it's only a matter of time until it works again, or the script might need updating. I will, however, not be updating this script, it's provided as-is and is and always was just a proof of concept. I'm working on instead adding this feature to my decky plugin, DeckMTP, with the next version, and slowly adding more USB gadgets and features with time.
Ah, I thought the plugin was cancelled since I first saw it mentioned years ago. Is it something you're actively working on, or are you waiting on something else before you can work on it?
The main thing I'd like is to remove the latency in Steam Link between the deck and my PC, since my router is on the other side of the house from where my computer is. And throughout what I've searched, it seemed like this script was the only thing I could find that could do it. Would the plugin be able to do this? And would it be anything I could use within the next year or two?
No, the plugin was never canceled, some things had to be rewritten first to allow this to happen. I'm still working on it, however this is unpaid work that I'm working on in my free time whenever I'm able to and I'm not burnt out from actual work.
Would the plugin be able to do this?
Both the plugin, and this script if you manage to get it to run, should be able to do this. I've seen people use this script for this exact reason.
And would it be anything I could use within the next year or two?
It's the very next thing on my list of priorities. A couple of months will do it most likely.
hello i new on linux, i have a steamdeck i have a error for to use this scrypt , i want connect at my mbp for play with steam link my bios is F7A0131 sudo /home/deck/Desktop/usb-ether.sh start -n
