I have a HTC EVO 3D with a very odd problem i dont know what i can do i look to all website in the internet and i didint find any solution yet . the phone It will not connect to my computer (recognized by the computer). The phone will charge when plugged into the USB; although, the computer cannot recognize the phone. I have already exhausted the idea of the cable being the problem.
Has anyone ever seen this issue plssss?
Make sure usb debugging is selected, and you can also download Wifi file explorer which allows you to see your phone contents through ip address (Wifi required)
(Don't ask me for help as I couldn't care if your phone explodes, eh! )
Have you installed the drivers for the phone?
If you have, download adb and run adb devices and see if it shows up there.
I had same problem with my "ex" SE Xperia x10.
It is problem with cristal connector which comes right after USB connector on motherboard..You probably teared it out while pulling out micro usb cable..So, only solution is to fix that with hair wire..I payed about 15$ for that, and it works like charm..
Cheers
I have had this same exact problem for almost 3 months. I have tried everything with no success. The only USB connection I DO have is in fastboot, but not in recovery or in the OS.
I would help any 'new' suggestions also.

Either you need to install drivers manually or enable USB mass storage in settings. It seems odd that USB works in fast boot but not anywhere else. If in windows try going to device manager when connected and see what shows up.

Okay so now whenever I try and connect my Evo to my computer I no longer get a notification on the top of the phone giving me options i change the usb cable and i try go to (Charge, Tether, Disk Drive, etc.). Debugging is not on and I have uninstalled WinAmp and PdaNet which I thought were potential causes of the problem. I also have the phone set to mount as a drive when connected via USB and I also checked the box telling it to ask me any time is gets connected.
what more i can do ? i try it in other computer and laptops non no works
+ i want to root my phone and i cant cuz off this problem

Well... I have a OG Droid 2.2.3. Whenever I connect it to my windows 7, it shows up as "device has malfunctioned, device.. unknown" everytime. I have tried reinstalling drivers, etc but the Computer never recognizes it as a Motorola device.
Also, my phone doesn't charge when the phone is on and connected to the pc, but when the phone is connected to the PC and I turn the phone off, it charges (but then it wont turn on unless I disconnect it).
Also, whenever it is connected, it never shows the USB icon/ or anything in the notification bar. So, I havent been able to root it yet. I have tried on 3 other computers (XP, 7, 7) and 3 other USB cables. Same results.
I want to root my Droid 2.2.3, I have tried z4root app, but it doesn't support 2.2+
How can I root my Droid without a PC, can I use terminal, etc and do it on the phone itself?
edit: just re-read what you typed sorry mate cant help
Tapped from a modded GS2
Tried it. This is all I get in device manager: I don't get any usb mass storage devices, or anything. I get 1 Unknown device, which if I try to manually update with Motorola drivers, Windows tells me they are incompatible and it doesnt install

your best bet is superoneclick 2.3.3. (just look it up or go to shortfuse.org) i got it to work beautifully on my moms phone. plus it works on 2.3.3 (no duh! lol). terminal emulator may work.... but what is the model under your "about phone." im not familiar with the "og droid" and im getting conflicting results searching for it... is it the droid one by motorola?
and uninstall the "unknown device" drivers, reboot your machine, and run the driver installers as administrator
update: what sucks is, if you were already rooted, adbwireless and ftpdroid could solve all of your problems, assuming you have wifi at home.............
i have an idea, post a link to the motorola drivers you have, and ill see if they install over here. if so, its a computer problem for sure. if not, then you probably need to get them somewhere else. (dont know why the source would have sucky drivers when other places wouldnt, but there's no harm in trying.
Tried your suggestion. Nothing. Still getting device is unrecog/has malfunctioned.
Its the Motorola Droid 1 on 2.2.3
Come on. There HAS to be a way to root it or install a custom rom without a computer! Ahh
Sorry. The only two ways I know how to root 2.3.3 and up use comp. Best Bet is fixing your connection with computer right now. Sorry. Try asking customer service? Maybe get the phone replaced. Then you have Shiney NEW phone to root!
ROOTED Xperia Play 4G 2.3.3
Anyone else have any other suggestions?

Did you guys every figure out what caused this and how to fix it? Just happened to me today...
Hi there, just wanted to let you know what the issue was so that others who Google this topic see this result. The most likely cause is the USB cable. Many USB cables appear to have all four wires/contacts, but actually only make use of the two that power your device. When it says "fastboot ac" what it means is that it's on AC, in other words, it's charging.
TL;DR: get a different USB cable until you get one that works.
USB is the problem
My Galaxy S3 GT-I9300 with android version 4.1.2 (baseband version I9300UBELL1, Build Number JZO54K.I9300UBEMA1) stoped connect via USB after jelly bean update... i think...
When i connect the phone via usb, its keeping connecting and disconneting...
tried unnistall kies, uninstall samsung drivers, installed drivers, then kies,.... usb debugging, factory reset, wipes, etc...
tried everything.... and the phone still the same problem.
anyone know why?
Could be a driver issue. Try plugging it into your PC, then select Camera (PTP) and Windows should redetect the device. If it still doesnt work, reboot into download mode and plug the phone into your PC in that state. Windows should detect the device and install certain drivers. After that reboot the phone like normal and try again. This is what I do whenever Windows tells me my USB device has malfunctioned.

Hi,
I just bought a new laptop with USB-C port, and when I plug in my Xperia 1 III, it only charges the phone, and won't detect it as a storage device.
I'm using USB-C cable that I got inside original box.
Is there anything I can do to solve this problem?
Phone doesn't offer me to choose transfer mode, when I plug it to a laptop's USB-C port.
Go to Disk Management and scan for new devices. Access directly from there.
Is the driver for that phone installed, check Hardware Management>USB hubs etc try to update driver or roll back if that fails.
If it doesn't show, use known good cable and inspect phone C port for damage or contamination. Can the phone see other OTG devices?
Try another port on the PC.
Reboot PC.
Play with USB options in phone Developer options. If already on, try turning Developer options off.
Check Event Viewer in Windows for error messages after attempting to connect.
Play with it... you'll find to issue eventually.

I tried everything, and also change USB connectivity in Developers options to File transfer.
Is original cable that comes in a box able for data transfer, or only for charging the device?
I found this in specifications of my laptop, does this means that my USB-C port is unable to recognize my phone?

I doubt that's it. The protocols are generally backward compatible.
Have you got a USB-2 hub lying around? Try going thru that and see if it works.
Hi guys,
I just bought a new data cable (USB-A to USB-C), and it works perfectly.
Thank you for all information you provided
Hi,
i try to connect my 12t pro via usb and it connects and disconnects continually, i have tried on windows 10 and 11 pc, the same problem. i don't use it often, only when i get a new phone so i can copy my music folders.
has anyone else getting same problem and if so, is there a way around this?
thanks
For me working normally. Maybe drivers you need to reinstall or try change USB cable ..

I've tried different cables and machine - still same.
Then take it to service, maybe your port is damage. How react when you charge your battery? Disconnect too? If not,then is problem in windows
charging is fine, it could be a windows problem (tried with windows 10 and 11), but could be a firmware problem. i have sent feedback, hoping they can help me.
thanks
Same here. At first it detects the phone but then it just disappears. Can only use it with Photo Mode and you cant really transfer files like that. Hope they fix it soon
Hallo,
Sie müssen die Entwickleroption aktivieren und das USB-Debugging aktivieren. Dann funktioniert es....
Hello,
You need to turn on developer option and turn on usb debugging. Then it works....
Thanks for your reply - but this did not work for me.
Your problem is more like a faulty usb port/flex cable or motherboard.
The fact that it charges does not mean the port is good since they are different connectors.
- On my working laptop (Dell) with win10 22H2 i can hear only plugin sound but cannot see phone as a storage device
- On HP laptop with win10 21H2 the connection works fine ¯\_(ツ)_/¯
Use driver inside the official Xiaomi Unlock package: Unlock (drivers)
I also encountered the situation described by the author. I think it is "Docking station" problem. Because as long as I don't use "Docking station" and directly put k50 from Ulta There will be no problem. But this is very annoying, because my other mobile phone can be connected to the "Docking station"
Your USB doesn't understand that it can't output 120w charging current. The phone asks for more, then USB overload protection kicks in. And it repeats itself endlessly.
I dont think its really the current load

0.44 Amp, its not the 20v 6A of the usb charger, wich make sense its the rate of normal usb
You probably have to much stuff on your usb or really bad usb port better pug it directly on a usb port and not on a hub to be sure
I had those sort of disconnect probleme on old pc with usb hard disk wich was due to too much load on the same usb and pretty bad usb
