One more USB question...

Hi there...
A quick question about the USB...
Is is at all possible to have a USB-port that can still charge the phone, but at the same time is "dead" when you try to connect the phone to the computer ??
I have also asked about it here:
http://forum.xda-developers.com/showthread.php?t=1179171
The story is that the Phone (SonyEricsson X10i) can be charged fine, but when i connect it to the computer, my computer say that the hardware is not recognized, nomatter if it is in flash-mode, mounted from recovery or in the normal way.
And the phone don´t even show anything about USB connection in the status bar eigther.
I have tried 5 different computers now, and 2 different usb cables.
I have also a X10 mini and a Desire HD that works fine on all the computers and both cables.
I have tried to remove software, remove drivers, clean computers, reboot, check the memory-card in the phone, install software and drivers and all other things i can think off...
It is two windows 7 and three windows XP computers btw.
So is it at all possible that the phone can still be charged, but data-connection fail ?
As i see it, there must be some kind of data-exchange or else the computers would not even say "hardware not recognized"...?!?

I'm not quite sure I understood your question correctly, but let's see if this helps:
I used to have phone that didn't have drivers for Windows I used at the time (I think it was Windows 7). That meant that Windows wouldn't recognize it (when plugged via USB cable) and will not therefore provide power to that USB port (hence the phone will not charge).
I was able to get around the problem by going to the device manager, locating the relevant "unknown device" and force installing some random drivers for it -- I don't even remember what it was that I picked -- something that Windows would allow me to do. Of course the port wouldn't work as a data connection like this, but since Windows now 'knew' the device, it powered the USB port and I was able to charge my phone from it.

My problem is that I actually can charge the phone ok...
But I am not able to make a data connection between the computer and the phone at all...
My question is then, if the usb connector in my phone can somehow be broken even though I am still able to charge the phone...?

I'm fairly sure that yes, the contacts or the controller can be broken so that you can still charge but be unable to establish data connection.

[Q] inquiry on usb port of alcatel tab t10

good day to everyone. firstly, i would like to thank you for having the time to read my post.
well basically heres my inquiry, my unit is the alcatel tab t10. i never had any problems with it until recently, my device's usb port suddenly stops working.
tried unchecking the usb debug mode, tried checking it but to no avail, the usb still does not work. it doesnt seem to connect to my laptop. tried changing the cable.
i also tried connecting my device to my brothers laptop.
correct me if im wrong, but when the usb fails to connect to any laptop, their should be a notification in the laptop that the device is not recognized. but in my condition, no notification shows up. its like my device does not really connect at all.
oh and if it helps, i bought an otg cable before it started malfunctioning. but the only thing i had conneceted to my device is a wired mouse and a wired generic gamepad, which both seems to be working perfectly fine.
also, if i connect my device to a wired mouse, it would work perfecly fine. i could also connect to a usb flash drive, that is via the otg cable.
so whats weird is that the usb cable does not work, but the otg cable works fine.
if you have any question or any suggestion , i would truly appreciate it.

Hmm.....well the good thing is the port itself isn't "dead" as you can still utilize it for OTG. My only suggestion is make a backup of all your apps and data and try a factory reset.

thank you for the suggestion guitarman2010. unfortunately my usb port isnt still working. i also reflashed my device's current firware. but still wasnt the solution i was looking for. i was just wondering if there is a directory under the root folder that holds the devices usb driver? would it be possible that the device's driver itself got deleted? i wam still at awe that the otg cable still works like a charm.
and another thing, is the male usb pin the same with the flash drive's pin? cause if i connect the usb cable to the otg cable it wont work, but the flash drive works normally.
sorry for the amount of question im posting
thank you very much for the suggestion. especially when u told me that the port itself wsnt dead. i can now breathe easier..
and future suggestion and advice would be appreciated.

do you guys know how to access the phoneutil in tablet? maybe i should change the usb option to pda? but i heard that its only applicable to samsung 4.0.3 devices? suggestions are appreciated.

I have seen this question before, the answer could be a number of things...
Try a different USB port, perhaps the one you are using is dodgy? or perhaps USB drivers need (re)installing?
Blow any dust particles from the micro USB port on your phone
Try a different USB cable, sometimes they become damaged and the data transfer cables no longer function
Check USB connection settings on your device - Ensure its set to MASS STORAGE
I hope that these suggestions help, if not then i'm unsure as to the best plan of action!

If the phone doesn't ask for permission to transfer files when plugged in...

Hi,
Thank you for the forum (first post).
Trying to get the S6 recognised by pc:
When the phone is connected to the laptops usb port via micro usb and cable (usb debugging on, samsung usb drivers downloaded, mtp:usb on) the computer makes the 'plugged in' audio sound but there is no 'permission to transfer files via usb' type message.
It does charge.
Does this maybe mean the charging port is broken/damaged, or the usb is broken?
Only other detail is that I once got the computer to say in a pop up that it was labelled as a 'samsung s6' rather than unknown device, which it normally does. This any symptom maybe its just a software issue?
Trying to get my computer to connect to the phone and have tried most if not all software solutions so far (including factory reset) and now looking if its hardware. Any tips to get it connected welcome.
Thank you,
David

have you gone thru the usual suspects? (diff cable, usb port, diff computer altogether, blah blah blah)

Same happens here, it was fine after flashed Rom now it wont recognize it for some reason

Question S22 ultra samsung dex

My s22 ultra suddenly does not work on dex. Theres no way to access the sd via a pc either.
I was using this exact setup and it worked fabulously.
As far as i know i went to bed one night and it didnt work the next time i went to use dex.

Reboot phone and pc? Is the phone recognised when connected? Try another cable, does it work on a different pc. Do other USB devices connect ok etc etc

i have rebooted both phone and pc. Same cable as when it did work infact the samsung original that came with the s22. My s9+ does not connect. Both phones DO charge via usb c.
I have infact reinstalled my pc and resest my phone to factory trying to fix this.
Still to no avail.

Does it connect to another pc? Usb pc hub might have failed

its a brand new laptop and it does power the phones. and it all did work fine. i can even power my usb c vape through the same port
there is not an alternative machine to test on

actually i just thaught of this, the last night i was using it i had the standard popup on my phone asking to allow dex to run. An ok responce and cancel or not now responce, i dont remember exactly.
Could this have done something if i hit cancel

also could there be something in the pc bios i may have not realized could effect this. Since i was on the same night trying to boot to a usb linux pendrive

When you connect your phone can you access its files on your pc? Is it recognised as drive

Ok so ive even reset the bios to system defaults and tried a regular usb to usb-c and still nothing

could it have anything to do with the phone usb connection settings. When you plug in a usb otg it normally would give an option for transfer or charge etc on the phones pull down menu and all its doing is saying fast charging

Try phone on another pc

Absolutely everything else works through usb mate.

What else can you access via USB. Drives, devices?

well i can access the standard usb port with an sd card reader. read write and even installed windows off it. So this usb to usb c should work fine.
If it were just the usb c hub blown this would not be the case.

im currently trying to see if i can run a lubuntu through usb bootable key and try to access the usb c ports from that.
I have been reading about my laptop and apparently it has a reputation of usb issues. lenovo x1 yoga gen 2 on win 10

Solved. During a bios update it appears the bios setting for thunderbolt usb-c was changed to disabled. As soon as i discovered this and rebooted it worked so if anyone is having issues with this they may want to check there bios settings.
4 days of struggling over. Dang its nice to beat a computer once in a while.

Do you have Link to Windows enabled on your phone? If so, turn it off and try running DeX.
