P605 Several USB issues

[bianconiglio95]

Hi XDA community,
firstly thank you for your all your great jobs here!
I own a P605 Galaxy Note 10.1 2014. It has been "soft"-rooted (through kernel bug, without KNOXing the device) but it has probably gone out of warranty.
I experence some serious issues with any USB-related operation, let me enumerate them:
1) USB Charging: when powered off the tablet charges normally (but slowly), when powered on the tablet charges (fastly) until the screen switches off, then it stops charging.
2) USB OTG: when attatching an OTG cable, the device detect it but when attaching an USB drive nothing happens
3) USB to PC: on a Windows OS, attaching the tablet results in a "Device Descriptor" error, even with the tablet in download mode, so any firmware flashing operation is impossible. On Linux OS there's a similar error, related to device descriptors.
Obviously, when I bought it everything worked fine. Sadly, I suspect an hardware issue... I'm asking you any kind of help: tests to indentify exactly the problem and, hopefully, a solution.

P.S. I've already tried changing USB cable/USB port/PC/charger/mood/wearing/house...:crying:

1) If not using the original charger/cable (or non compliant) then there's a possibility thad the data pins of the charger are not shortened. You need a charger compliant with our tablets or data-pins-shorted cable. (you can do it yourself but the cable will only be used for charging)

2) try Es file explorer (remember ntfs is not supported)

3) install kies or try

(just the usb driver)

I have exactly the same case as #1 and I fixed finally. It's because of the bad contact of the usb cable. Open the back cover (gentle and slowly prevent broke it), disconnect the usb cable from the adapter near camera, wash your hand and keep it dry, touch the golden finger one or two times with your cleaned finger, then connect it back with a little push it to the end, make sure it lock firm. ( I also use a piece 3M plastic tape to stick on the surface ). Power on and test, no problem and then close back the back cover. My machine no more that problem again. Sorry for my english not so good, and hope this can help.

With Davidmueller's Lineage and RR there is a (recurring) charging problem with usb cables. You need a cable like the one supplied, where the second GND line on the m-usb plug is not connected. The plug of the white original cable has the contact missing, i bought a recent, black Samsung cable with 5contacts,also working. None of the other cables i tried, did. The problem was there almost a year ago, got solved and re-occured during the last updates.

Results after the replace of the usb module.

As suggested by Jan&March, I tried cleaning the usb module connector on the motherboard. It solved EVERY issue for about 3 days, then they came up again. So I thought that maybe, touching and cleaning the connector, there was some bad contact on the cable. I bought a replacement part for the usb module. It has been working for about 2 weeks before showing the same issues today. I hope I'm helping someone with my experience. Any suggestions?

The pcb jack may have bad solder joints. I never had the case open, but i think the usb and display connectors belong to the components bearing most of the pressure exerted on the back cover. Except the battery and the metal shieldings on the pcb stand out more,which can only be told if you have the back cover removed.

Thanks, so what do you recommend?

That would require re-soldering. It's hard to tell, it's less likely if the connector's aren't among the most prominent parts under the back cover and won't make contact with it. I can't tell from the pics i've seen.
