I purchased this cable off eBay for a spare. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=300510528360
When I use this cable the charge function works fine but when I plug it into my PC Windows gives me an error loading the MTP driver and there is an <!> mark on the MTP device in device manager.
When I swap in the stock cable in the same USB port it comes right up without error.
Obviously the difference is the cable but my question is:
Is the cable DEFECTIVE or just incompatible? It is cheap enough where I'll just order another one. I read numerous times where the GTAB 7" cables should be fine ..... or was that for charging only?
I’m having a problem charging my AT&T Galaxy S3 rooted. No USB cables work to charge my phone. Whether it be the one it came with in the box or one from wall mart. I’ve also tried all the USB cables, HTC, Samsung, and others. Also tried the USB mini Best Buy sells for these phones.
Before I had this problem USB cables would work just fine but all the sudden they stopped working.
The only way I can get any USB cables to work is if I hold it at an angle and itll charge and stop randomly but charges very slow if held at an angle.
Only way I can get my phone to charge is if I use a wall charger. I have tried all the USB cables with my car, lap tops, and usb to wall adapters.
HELP PLEASE!

That's a hardware problem.. not much we can do about it. You most likely damaged your USB port and will need to replace it.
You can contact mobiletechvideos.com for their services if you don't know how to replace it yourself.
I had recently purchased the C6502. At work I do not have AC power outlet to charge the phone. So I generally used to charge my old smartphone (LG Optimus 4X HD) with a blackberry USB cable. I used to charge my old phone by connecting to the monitor's USB port using the blackberry cable. Though the phone showed as "Slow charging", it served the purpose.
But now using the same Blackberry USB cable and the same USB port, if i try to charge the C6502, it just lights up the screen and does not show any charging indication or the notification LED light.
Am I missing something here or the phone charges only with the original Sony provided USB cable?
Note: The same USB cable and the USB port work perfectly fine for other smart phones my colleagues are having like Galaxy grand, Lumia 610, HTC Desire SV etc. Of course when connected to the usb port all these phones are showing as slow charging, but they do charge slowly. But my XZL does not even charge. So I am definitely sure the cable and the port are perfectly fine.
Is there a way I can charge my XZL with the USB cable using the USB port?

Let me explain it more clearly.
At my work the USB ports on the CPU are disabled. But the monitors are having USB ports which can be connected to the CPU through another cable, so that USB devices can be connected to the monitor's USB ports insteading of leaning till the CPU under the desk. But those ports are not connected to the CPU so the ports on the monitor just act as a power source but not as data source. So we use the monitor's usb ports for charging our devices like phones, ipods etc.
As i had already told that my XZL screen lights up when connected to the port using the blackberry cable, but no indication of charging as well as no LED light. Same case with another colleague's Xperia SP.

as simple as your device does not detect any pc therefore it doesnt accept charging depends from phone to phone

So sony does not support "chaging only" mode using USB cable. How pathetic !!!. Supposed to be a "Smart phone" but really do not understand why cut down basic features.
Can anybody confirm if this cut down of a basic feature is a standard for Sony phones?

USB charging
I have observed two things -
1) Yes, it does not charge in some cases. I have a power bank cable, with this cable it charges for some time but then it just stops charging without any reason. If you reinsert the plug, it starts charging again.
Other times, it does not charge with USB ports, for example my car music player's USB port. But what I have noticed is, if USB connectivity mode is changed from MTP to MSC or vice-versa it works.
Also some cables do not have two spring notches, and fit quite loose. In such cases pushing cable vertically up or down gets it charging again. But this is very very rare case.
2) I was not able to charge it from front USB port of my PC, but when connected to back USB port, it was charging fine.
My conclusion is, it does not charge if charging rate is too low or mode is incorrect.
I would suggest, try with original Sony USB cable in your office and check if it works. If still it does not, change connectivity mode. Else its a cable issue(not exactly, but phone and cable have some mismatch).
PS - I had similar problem with my chinese tablet. Out of more than 5 cables, It charges with only one cable from Nokia(it does not even charge with original tab USB cable ). I think there are separate data pins and power pins. But data pins can double as power pins. I think there was some damage to the tab USB pins, because of which data pin no more works as power pin and hence it does not charge and requires cable having power pins. Can somebody throw more light on this?
Relax its just u need a pc on to charge it it happens in my case too n my phone works fy9 with any cable

so i have two usb cables and original. 2.0 amp samsung wall charger, the samsung cable i use for wall charger at home so when i setup my s3 as a AP i need constant 2.0 amp from charger keep up with the demand and charge the battery at same time but now i cant do that i have turn off hotpot and leave the phone alone so i can charge. i brought in my car usb cable, and now i can hotpot and charge at the same time no problem, so what is the problem with other cable? i mean cable still works and i still can use it for data transfer etc...
just cant use as heavy demand cable.
I have some cables from the "box o' cables" we seem to collect that have the same issue. Some of them won't keep up with the s3 others won't keep up with my n7. I notice it more with older cables so it seems to me that its the cable breaking down or wear on the contacts inside the connector itself.
So.....
I connected +5v to the usb ground pin on my phone and connected real +5v pin to ground.
Now my phone refuses every charger claiming that it is an "invalid charger type" and that I should only use the official charger that came with my phone. (which I do)
There was also some error about "charger suspend detected" (or similar).
The led still lights up when connected to a charger even when not charging.
It turns off ~5sec after disconnecting the charger (as opposed to turning off directly)
Sometimes the led doesn't light up at all and dmesg spews a bunch of errors.
Also when connecting an usb otg cable, it doesn't add the 2 usual devices (usb 2 root hub and usb 3 root hub) to the list of usb devices (aka output of lsusb?).
It adds those 2 devices only after connecting a to a normal charger and then to the usb otg cable.
The usb otg cable is always supplied with voltage even when there is no other usb device connected to it.
However connected devices aren't being recognised anyways except when connecting to a powered hub or using a Y-cable.
MTP, UMS and ADB all don't work.
(fastboot not tested yet)
Charging still works in 3 ways:
Shut down the phone and charge as always.
Connect the phone with an otg to a powered usb dock.
Connect the phone to to Y-usb otg cable and connect that to power.
Any ideas on how to get everything back to normal ?
Or at least how to get adb working (over usb)?
Just in case:
DON'T TRY TO REPRODUCE THIS ERROR JUST TO GET Y-CABLE CHARGING WORKING.
