Hi all,
I'm experiencing the above problem. It started last week when I tried to reflash the firmware to a third party firmware. The unit could power up as normal, wifi, bluetooth all working fine but not the USB. I've tried installing a utility which switches the mode from RNDIS to USB but it still failed .. hard resetting the device does not help either. Is there a way that I could revive the USB connection? I couldn't sync my contact etc at the moment with my PC.
BTW, currently I'm on Onyx Jr. 4.1.2. I could not update to any firmware due to this and I don't have microSD to SD converter which I could use to copy the firmware to the microSD.
TA.
Disconnect sync cable. Reconnect to different usb port on computer. Right click ActiveSync in taskbar. Click connections. Make sure "Allow USB connections" is checked. If above fails, uninstall usb adapter in device manager, reboot computer. It'll reinstall with stock drivers after reboot.
It may happen due to faulty USB cable. Try and use another cable and on some other computer and check
I've tried all that I could think off including removing activesync and reinstalling it back. I've few miniUSB lying around and I've tested many of them but my notebook just did not want to recognized the htc touch. I've tried using those cables with my wife's tytnII and they worked .. could it be the hardware problem inside htc touch itself?
Tried with a new USB cable found in my newly bought GPS and if I reseat the cable properly, my notebook could recognised the htc touch. So I guess a new cable does help.. thanks all for the help.
Hello!
I've bought used Magic few days ago, and last night I wanted to root it, but when I try to connect it with computer - nothing! No USB icon on Magic, no new device on PC, just charging. I have original 1.6 android on it. Tried 4-5 different USB cables.
What can I do? Is there any way to fix it? Can I do rooting and flashin new rom from SD card, without usb?
turn on usb debugging in settings/applications/development
Already tried that. Doesn't help.
BUMP
Anybody?
could be a problem with your usb port on computer, try another port or try the phone on another computer and see what happens. also did you try the usb headphones ? are they working fine?
Hello! I have a major problem. After flashing back to stock, my phone suddenly cannot connect to the pc at all. Once I plug in the cable the phone auto restarts and is stuck in a bootloop until I remove the cable. It also doesn't charge if connected to the charger. Any ideas on how to fix this?
More info regarding this case. Phone is an lg d802 32gb model. Reverted to stock from cloudyg3 rom. Right now I cannot access download mode as the phone auto restarts once I plug it in the pc. Tried with 2 diff pcs but the same problem.
hmmm

Try changing the usb cable.
Hi, I tried 3 diff cables but it still has the problem. Also, I think the cables are not the problem as those cables do work for my other phone (both in charging and connecting to pc). This is a really weird issue. Anyone else experience this?
I have the same problem, phone restarts when connect to pc, if you connect and disconnect several times the usb cable, sometimes it works, you can try this to access your phone, turn it off, connect usb cable, and the power off, sometimes it work for me, also to charge the phone.
Anyway if someone can help us.
Thank you.
I installed this rom https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 on the same ROM but rooted now my phone does not support turbo charging and if I plug my phone to the pc is not displayed, before that clean the micro usb port of my phone, I do not know if it damaged it or does not support turbo charge for having flashed wrong.
Could you tell me what the problem is? if it is wrong flashed as I flash it back if I can not connect it to the pc? or is it the micro usb port and do I have to change it?

No rom affects turbo charging in any way. Check the temperature of your phone and the connection/cable. Reflashing may be an option to.
@megasjuan turbo charging is hardware feature and has nothing effect even of wrong flash (many one did wrong flashing and lost one imei of slot-2 and with model number, in your case it seems to be fine, right? )
You said you cleaned usb port, it may be damaged that while, or may be not.
Turn your phone off and plug it to charging, then see what that charging screen says.
For computer connection, try updating driver / remove and install again / change usb cable or different usb slot of computer.
Then you can conclude what's wrong.
Thaks

I sold my phone, i use it a lot, and i need a fast charge phone, thaks for your answer
my nexus 6 will only charge no data transfer and pc wont recognize it. When i connect it to the pc it goes staright to charge mode and the usb trident symbol doesnt ever appear. In developer options usb configure is stuck in "charge mode" only. Ive tried different roms from pie to mm . i reinstalled bootloader and radio, tried twrp back ups and still the same. Had new charging port put in phone thinking that was the problem but didnt help. Ive searched google but couldnt find anything. Any Ideas, really appreciate it thx
When I installed stock rom which was android 7.1 it changed phone back to encrypted. Now i have to format internal drive in order to install a pie rom. Does anyone think that formatting internal drive might fix problem with not being able to do anything but charge phone from usb port, because if that doesnt fix it there would be no way for me to put any rom on my internal drive to install it.. Does anyone have any suggestions

Just to double check that adb devices shows your serial #. If not, it may be a driver issue.
Computer doesn’t see it, when I enter adb devices it doesn’t show up. Nothing shows up in device manager either: Also when I enter fast boot on the phone “power lower volume button” it says “connect usb data cable” I’ve trued numerous cables that work fine on my other phone. So it’s not the cable. After I plug them into phone it still says connect usb data cable.
I also have a thumb drive with a micro usb connecter that used to work on the phone. Now the phone doesn’t see it when you plug it in to the phone. But it works on my other phone so it’s not the thumb drive

It sounds like a driver problem. Is it a windows PC? Have you tried installing the Google USB driver? I've had similar issues, and reinstalling the driver(s) has worked for me.
It’s windows 10 and I reinstalled driver, other thing is in my car when I plug it in to the usb slot for android auto, it doesn’t show up in my car either and it used too.
It’s like the phone is stuck in charge only mode and I can’t get it out of that

When you connect your other phone to your PC, does its serial # show up in adb devices? If so, I'm out of suggestions.
1 more thing.. Have you enabled USB debugging in Developer Options?
Other phones shows up and in devolpers options in “usb configuration” you can set it to mtp but when you hit enter it goes back to charge only. I was on” aiop 14.0 rom” when it happened but it was working fine on that rom , then one day android auto kept saying connect usb, so when I got home I tried to plug it into pc and nothing. So I replaced charging port thinking that was problem but it didn’t help. Flashed other roms and even went back to stock, reflashed bootloader nothing helped. I was hoping someone here had seen this before cause I googled it and nothing like this could I find

Forget USB configuration for a minute. In developer options, under debugging, USB debugging needs to be enabled.
usb debugging is enable also. even tried turning it off and back on again, didnt help.
you know when you connect phone to pc and you normally see the usb trident symbol on your phone, well when i connect it to the pc i dont see that symbol it just goes straight to charging but even charging i should still see the usb symbol and i dont,
