How can I tell if my USB port is busted or my phone is corrupted? Only charges now.

Charging over USB works fine no matter the cable or the connection but it no longer will show up in Windows on any PC as a device. I tried flashing roms, changing cables, and doing the usb fix with Terminal listed in the sticky but it doesnt connect or will it know it's connected to a PC.
Can the port be broken so data no longer works but charging does?

its not the phone its the computer, try another computer

I have tried 3 which is why I wonder if my phone is broken, but it charges fine.
On all PCs the charge light comes on the phone with no problems but with all of them none of them detect a USB device being plugged in.,
Even in recovery if I do a USB-MS mount nothing happens.
Can the usb port break so that it charges with no issue but wont connect to a PC?

Does the phone recognize your sdcard?

I think the solution to your problem can be found in this fix

The USB port on my Evo 4G will charge but won't show up as as a device on my laptop. If I hold the USB cable at an angle, though, it does show up. I think mine is busted, maybe that's the case for yours.

Yup. Last night I completely wiped it and had the phone format and set it up fresh.

Do you think the cable is busted or the phone? I have tried multiple cables on multiple PCs and nothing happens.
So then it is possible for the phone to be unable to connect but still charge fine?

Have you tried mounting when in Recovery?
It really sounds like your cable is weird. The power lanes are on the edges for USB, meaning that the port on the phone is probably physically fine. The cable, however, is vulnerable to damage on any one of the four wires.
If nothing works, then perhaps something internal is busted. What do you need to transfer from your computer? Perhaps you can do it by connecting to your computer through WiFi for mounting the SD card and adb?

Its your USB port on you phone, theres 2 pins or smoething broken inside your phone thats causing the problem. I had the same problem on my Evo were it wouldnt connect as a storage device and would go into car dock mode. I took it to sprint and showed them the problem and they replaced my phone. As long as you dont have any physical damage such as the screen being cracked you should be fine and they should replace it free of cost.

Make sure that your cable is not one of those charge only, car charger type cables. Typical car charging cables don't transfer data.

Yeah, that's pretty much it. If I wiggle it just the right way the computer will see something but it will go away as fast as it shows up. Doubt Sprint will do anything as the phone is a few years old, I dropped the protection plan, and it's rooted to heck.
I'll just keep it running until this fall and upgrade when the new Nexus line comes out.
Hopefully.

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.

Broken USB?

I've had a charger go boom (explode). And since then I can't connect my nexus to PC via USB neither does the tablet itself recognize when it's being powered, altho it charges. No indication tho that charging is going on just eventually it reaches 100%
Any ideas if there's some kind of fix for this? I doubt I can return it to RMA since it wasn't charged by original charger and even more importantly the thing is rooted with custom ROM. Without being able to connect via USB to do fastboot commands i can't even return the thing to the stock. Nothing is working via USB connector. Tablet just doesn't recognize anything being attached. PC host or charger
I've opened it and tried disconnecting battery and connecting it again but that didn't help. USB connector doesn't seem to be fried tho.
Any suggestions are welcome

Nope haven't bothered. Probably I would need to do some soldering. I'm just being happy I can power the thing and use it wirelessly. It will be pain in the a** when I'll need to upgrade bootloader.

I use wireless charging. Doesn't solve fastboot and other issues but at least you can use it.

Lost usb connection and quick charge after rom update

Hi guys,
I had a xiaomi.eu beta rom installed from feb/18 and i decided do update to the last beta available 8.4.28 through twrp. After that i lost quick charge and my usb connection. My pc (or any) dont recognize my phone, when i plug the usb into my pc nothing happens, nothing new in the device manager. I tried different cables and charges. Cleaned my phone usb type c port with isoprophyl alcohol and a electronic contact cleaner, didnt fix. I decided to do a full wipe, installing a Global stable 9.5.2 do see if it would fix my problem, but it didnt workout. After that i foundout thay i lost my twrp and a generic recorery from xiaomi was instaled. Yesterday i got a update via OTA to 9.5.4, didnt fix it. Now i have a phone with slow charge, no usb connection, no twrp, no root. My only solution now is to find an APk that root my phone so i can install twrp using flashify and try the rom from february i was usong before all of this. Does anyone have/had this issue?

Does this also happen when connecting with other computers?

Yes, i tested with my laptop and my computer at work. Also, my otg doesnt work. I can reboot to Fastboot mode, but i my pc doesnt regognize this way too.

i have the same problem. currently i am on V9.6.1.0.NAGCNFD. and i lost my USB connection to my pc. as well on all QC chargers i have, i cannot charge my device any more. it starts to charge for 2-3 seconds and then stops charging. slow charging via regular usb ports/chargers is the only function left on the built in usb-c port.
i tried various pc's, cables & chargers.

I fixed it on my mi5s. it was actually a hardware problem . after changing the lower board containing the USB-C connector inside of my phone, it all is working again.
the board is available for a couple of USD on aliexpress.

Just wondering - did you manage to fix this problem? I have the same issue - but AliExpress USB-C module replacement didn` help.

Mine is working fine since i replaced that module.

Question {SOLVED] Cannot connect ZFold 3 to PC via USB (only charges/no transfer options)

When I plug phone via USB into PC running Windows 11 the phone will only charge.I don't get any options on the phone for file transfer and the PC doesn't detect it. Any tips. It's usually pretty straightforward.

maybe a driver problem?

It came down to the cables I was using.
The Huawei cable I use for the 65W charger didn't work. The Huawei cable for the 15W Wireless Charger didn't work. Found another cable in my cupboard (don't know what or where it comes from) but it now works and I get the options for transfer on the Fold and it shows up in PC's file manager.

Thanks for replying. It was a cable problem.Doesn't seem to like Huawei cables.Very strange.

So the Huawei cable ends are Purple and Orange in colour. Both cables don't work for transfer but only charge when plugging into your PC. The cable end which is White works fine.
Just in case someone else runs into this problem since the phone doesn't come with a charger and cable and you might use your Huawei cables and find you can't connect to your PC to transfer files but only charge.

That isn't new. Samsung had before issue where if you used non Samsung cable the Samsung phone will nag about port was wet, when it wasn't. But now it seems Samsung finally got rid of that limit so charging with any USB C works now. But it seems you need to use original cable for phone when it comes to transfer of files.
