Anyone having USB connect issues?

Sometimes my phone will not charge when connected to the wall or my computer. The problem usually goes away on it's own, but when I need to charge I generally need to charge.
Sometimes I cannot access my phone via USB on PC either.

Only with data to and from the computer. No charging issues at all.

I've never had issues when plugged in to computer (USB). I frequently have issues when plugging into wall charger, but I think I have a bad cable. Phone will recognize charger connect, sit for a second, and lose the connection. Charging stops while cable is in. I bought a cheap cable on-line for the wall charger. I guess you get what you pay for....!

I have issues with usb connnect to computer since flashing cm6 8/13 nightly. Will not charge or mount usb.
Restoring back to 8/11 seems to fix issue but can't seem to get any newer nightlys to work or rc2.

Kind of sounds like a loose connector. I bought some micro USB cables from monoprice and the size of the connector was just a tad smaller than the plug for the phone. So if the cable wasn't plugged in and propped up in a certain way, the phone wouldn't charge. I just bought some new cables from monoprice (the ferite core ones) and problem solved.
I guess when this happens to you, wiggle the cable a little and then hold it for a few seconds at a certain angle and see if it starts charging... if it does then you know you need a new cable.

I was having similar issues and with my sd card permission issues I simply uninstalled my usb drivers and my removable disc drivers for the phone on the computer I think there was like 3 sets and haven't had an issue since.

[Q] USB Charger

Hi,
I've used a USB charger on all my phones for a few years now. Just plug phone in on my desk and no worries. However my new Defy doesn't seem to take a charge from the USB on my network device (it's not a full PC). However my HTC HD2 could get a charge from it so:
1. Is the Defy more power hungry that it won't charge from an ND (I assume NDs put out less power over USB than a PC)
2. Does it just not show on the battery on the Defy that it's charging?
3. Have I missed something simple? I've gone into USB connection and selected charge only. I can't install drivers on the ND though, could that be it? The ND hasn't said it's found new hardware either though.
Thanks in advance for advice

motorola has a notorious reputation on this, they require a usb driver to be installed for charging some of their phones...
i think there's some strange combinations at work about this but, just use a standalone charger and it should solve the problem.

Thanks. I thought it would be that.
Bit short of plug sockets at work but I'll figure something out

Another point to note is that the Defy is very fussy regarding USB cables. A lot of cheap ones will pass data but no charge.

Would you consider hacking a usb cable to make a charging lead? A standard usb lead plugged into a PC will try to enumerate with the PC before it starts to draw power from the PC. However if you hacked a usb cable and shorted the DM and DP lines on the phone side, the phone 'should' detect the cable as a mains charger rather than a PC, thus enabling charge without any drivers on the PC. It would be something like the attachment...

Thanks for all the replies. Although my USB cable wasn't cheap and was capable of charging an HD2 which must be more power hungry than a Defy, it turns out the Defy is really fussy. It's charging fine through the Motorola USB lead on my network device.

My USB loading experience
Hi,
just to share my exp:
- loading with most USB loaders: fine
- My Car loaders and my multi power adaptor with usb can load everything but the defy
- on Computer no problem (some say you will have better battery performance when loading on non Computer: I can´t see a difference)
- cable doesn´t change anything

I've bought a couple of USB cables from ebay. My Defy seems to connect and disconnect when using them, like it has a loose connection. If I use the Motorola one, of course it's fine!

can't connect to usb

i can't connect my sgs2 to USB storage. when i plug in the usb cable to my computer and phone it will charge but nothing else happen. i had stock rom before but are currently using jug 4.0. i thought it was the rom so i downgraded to 3.69. still the same problem. i mean i can do anything with the phone just can't let my computer detect the phone. i tried to reinstall the driver, nothing works. please help!

Is your cable a samsung branded one? I had that same problem but with stock rom. I used an LG branded cable and the phone would connect to the computer and charge, but would not go into USB mode.

yeah, i am using the one that came with the phone, i guess i will try to use a different one. it was working fine before, don't know why it just stopped!

This has happened a few time for me. Sometimes the phone has only needed a reboot, the wire definitely plays a big role... I bought some cheap cables that didn't work at all... some of the older roms wouldn't show USB connected unless drivers were installed (kies). An issue I've more recently unveiled is after using an MHL adapter sometimes the USB will connect for 30-60 seconds before unmounting storage again. Hope that helps
My SGSII HercuDom needs more w00t. It always needs more w00t!

I had the same problem on a stock phone (purchased in late Oct from T-Mobile store in Arizona). I would connect it to the computer and it would charge but would not recognize the USB function (for data transfer or modem use).
Took it back to T-Mobile and they overnighted me a new one for no charge. New one works fine.

Cant charge or connect to USB

So far i've tried: Change the battery, change the charger several times, put factory settings and still the same problem, can anyone help me?
Thanks,

USB Problem.

Just got a brand new Samsung Galaxy SII T989 from T-Mobile this week, it really is a great phone, only I have a single problem.
The phone charges, it functions properly generally speaking (calls, texts, camera, wi-fi,etc...) but as soon as I connect it to my computer it freaks out.
It acts as if I were disconnecting and reconnecting the USB cable 2 times a second. I can hear the phone making the beeping sound it makes once you connect it to the USB every few seconds and in my computer (Which is running Windows 8 x64, just in case.) I can see the "Safely remove hardware symbol pop up and disappear a few times a second as well.
This is really frustrating... I love to take pictures and videos and edit them... I'd also love to copy some music over as well...
So far I've determined it can be the cable, bad drivers, or the phone itself, I just hope it's one of the first two.

Try re installing the correct drivers or switching the usb hub. If that does not work it's most likely the usb cable, swap it for a different one and you should be fine considering you bought the phone new.

Or you got a phone with a bad motherboard which would be crazy considering its new but that kinda sounds like the problem I had

Alright cool, but how does one find currently installed drivers when the device isn't plugged in?

Ok, does it get better or worse if you hold the cable with your finger when it is plugged in to the computer and phone and move it around a bit on the phone end? If so, I even got a Nexus 7 brand new from Google that the charge cable phone end was bad and would not make a good connect and I had to use a different cable and it works fine with my tablet.
If you use the same cable in your AC charger and on the computer then prolly not the cable.
It could be something in Win8 if it is trying to scan your USB port [like maybe a whacked anti-virus].
Have you tried a different USB port on your computer to see if maybe the one you were trying to use is bad itself?
If using a USB hub between your computer and the phone try removing the hub from the equation and connect directly to the computers USB port.

I am using a HUB on a Razer Keyboard that I've always used BUT now that you mention it my webcam had the same problem. It wouldn't work with the HUB on the keyboard. I'll try another USB slot (My computer's other USB slots aren't very accessible which is why I've hesitated to try another slot.)
I don't use anti-virus and yes, the cable works perfectly fine on the AC USB to Power adapter it brings.

I love you. It worked. It's the USB hub which doesn't allow much power to go through to the connected device. Thank yo so much.

ASRock Z370 EXTREME4 and USB-C NOT Working for ADB Sideload

I have a very specific problem.. Not sure if I'll get much help unless you have the same setup as I do but here goes!
Ok, I think I've got everything set up correctly here but I just put this system together this past weekend and decided to try out the USB-C port on the motherboard as my case doesn't have it on the front.. Noticed it takes forever to recognize I've even plugged anything in (Pixel 2 XL). Once it's recognized it's great! Is there an issue here with this? Driver issue maybe? I'm reading through the manual and there really isn't much there.. Plug my device in, 5-6 minutes later I hear Windows recognize it's plugged in. Windows 10 x64 Build 17093.
Also, after it delays in recognizing I have the phone plugged in, everything works BUT ADB Sideload...

I never could get my PC to recognize my device when using the type c port. Always had to use the USB port. I don't know if the type C cable recognizes data I think it might only be a power cable.

That's what I can't figure out.. Someone else is having the same issue with the same exact motherboard I have but seems worse off than I am. Mine just takes a while to be picked up as plugged in but eventually works fine. I installed Ubuntu and it took only a couple minutes to pick it up.. Going to try fastboot/adb as that's never worked..

Stop trying to use a USB c to USB c cable, this has been advised against, doesn't matter what motherboard you have. Go grab your self a normal USB to USB c cable, they work much better and should pick up your phone immediately.
