Misc Linux QCMA connection stopped working.

[Kiiro_Yakumo]

Hello.

I've bumped into quite a problem recently and after exhausting some options I guess it's time to write it down here.
Until recently, about 22nd of April QCMA on Linux Fedora worked like it should for years. Transferring screenshots by Wi-Fi or USB in the past as well but I believe for about a year it was Wi-Fi only.
Fedora had recently new release so I've upgraded it. I tried to send new screenshots two or so days ago and no luck.

The transfer just ends but no files are being created on PC side. QCMA doesn't even light up as connected either. Trying to use content manager on Vita side to connect gives me "The device has been disconnected" on QCMA side instantly. Attempting to with USB gives a wall of such notifications for a short while. I have tried with OpenSuse Tumbleweed through USB HDD, both Wi-Fi and USB connection to rule out Fedora as the culprit and no dice either. Then again, OpenSuse Tumbleweed is even more of a "rolling" with packages so it may be not enough of a proof. The same happened with OpenSuse Tumbleweed on Virtual Machine.

For the record, I can still sync trophies and do FTP so it doesn't seem like hardware problem on either side at the moment.

To make things more confusing, I have dug up old Windows 7 on Virtual Machine with QCMA and... it worked through USB at least, so it's not faulty cable or port either it seems.
Can't test Wi-Fi on Virtual Machine as it doesn't connect directly to the rest of the network and such.

I have disabled plugin most recently used just in case as well as UCDC as it was giving a specific error through USB so at least that part is ruled out.
I did a bit detoured but successful database rebuild on Vita side.

The Vita itself is on 3.60 with Enso.

Thank you in advance and have a good day~!

EDIT #1 - oh right I forgot, tried to check with terminal what it will output when attempting through USB (I think the Wi-Fi has similar output just once instead of few times over):

PTP: Opening session Vita connected, id: [here is some ID written] vita_info.xml:1: parser error : Extra content at the end of the document ><gameThumb type="0" codecType="17" width="192" height="192"/></VITAInformation> ^

EDIT #2 - got a bit older Fedora (two releases back) to check on Virtual Machine and it worked over USB as well. It seems that it is software problem definitely, not hardware problem. The question is what exactly is failing.

After long battle with probably everything possible I was able to solve the problem somewhat.
Topic can be closed, marked as solved and all that stuff.

It's a secret. You're not supposed to know. Just kidding. In all seriousness, it would be so kind of users who post about a problem, and later find their own solution, to post how they solved it, instead of just posting "I found the solution, topic can be closed". That doesn't help anyone who could face the same issue. I hope OP can help you.

I guess I didn't phrase it properly so here is the proper version.
When I said "everything possible", it was metaphorically really that, everything that popped into my mind, attempted. Since I couldn't find help on the network I wasn't really keeping track of anything done. Stuff included many things that were probably not related to the problem at all but I couldn't know it at that time of course.
When I said "solved the problem somewhat", I should've put emphasis on "somewhat" part. It's not trully solved, it's shaky and about as stable as chaotic energy put into a bottle with a cork.
There is no guarantee this method will work anywhere else, especially that the new user with his first post just wrote the classic "doesn't work for me either" without specifying anything else, even basic info.
Finally when I said "marked as solved", I didn't mean it as "I know what happened and what didn't work", it's only just that, "topic can be closed", nothing deep or poetic about it.
