The problem just started.
What works:
1. Low speed charging
2. Access to OTG memory card
Not Working:
1. Connecting to PC. Unknown USB Device (Device Descriptor Request Failed) The PC has the correct LG driver.
2. Fast Charging
3. Android Auto USB mode. Phone won't negotiate with the car.
I have cleaned the USB port with electronic cleaner and sand paper. It made no difference. The port wasn't dirty to start with. I have not done factory reset since the problem looks more likely to be hardware.
Any suggestion?
Cord gone bad?

Not the cord. Already tried several. The cords work fine in fast-charge mode and Android auto with other phones.

So, has this device connected to the mentioned PC before? If so, and nothing has changed (like driver update etc), then, sorry to say, but it absolutely sounds like the usb port is an issue.
Even if out of warranty, I'd plead my case to LG. That shouldn't happen. Has it gotten wet? Is any part loose in there?
good luck
I also have a USB problem, but mine keeps asking what I want to use the USB connection for i.e. charging, power supply, file transfer, photo transfer or MIDI device. And the wireless charging doesn't work either.

I got the same problem, I tried to work around the USB port and it fixed itself. Probably got some dust in the port. Try to tug the cable a bit and reconnect. Or you can try different cable.

I just got the Captivate last week. I've noticed that it doesn't recognize the USB connection if I just plug in the cable at "normal" speed. If I plug in the USB cable s-l-o-w-l-y the phone recognizes the cable and everything works. If I don't plug in s-l-o-w-l-y the computer gives me a USB inserted sound but the phone doesn't seem to know it is connected.
I've also noticed that the phone will (with the slow insertion) always say usb connected once the cable is inserted even if the computer end is not connected.
Anyone else experience this? Thoughts? Bad phone or bad cable?
What ROM are you using?
What USB Drivers do you have installed if any?
What OS are you running?
Pretty much it depends... if your using a custom ROM that could be the culprit though it doesn't sound like it from what you have posted.
Try re-installing your USB drivers for the Samsung Captivate. Make sure your running the correct version. (Search for Design Gears OTA Odin 1 Click post - has the drivers linked there).
And of course... it could be your computer itself. Reboot fixes 90% of all computer issues
Firmware 2.1-update1
Baseband I897UCJH7
Stock - not rooted. Drivers do not seem to be the issue. It happens on multiple computers. Rebooting phone and/or computer does not change things. Same under Windows and Linux.
I kind of have to slowly inch the USB cable into the phone until the phone recognizes it. If the computer end is not connected to anything, the phone sometimes still will recognize the USB cable and say USB connected. If I plug the phone end in first, then the computer end the phone doesn't recognize the connection.

Hey guys,
I have 3 USB ports on my laptop. I used to love connecting my TP on this one port until it just recently broken. Then, I tried other USB ports to connect my TP but always get the blue screen on my laptop after I tried to do so. I want to install ICS on it but was unable to do so as my laptop keeps rebooting. Any ideas?
BTW, my TP is running CM7 3.0 and running the ICS ADW theme if that would ever be the problem.
Does the computer do that when you use a different USB device?
If it is only the touchpad, I would say try connecting through webOS and see if that does anything different. Also try turning off USB Debugging in Android so it doesn't try to load the driver.
Sounds like something is shorting out causing the laptop to shut off and reboot as a fail safe. Check to make sure the laptop's USB port is good by trying other devices, also try another microUSB cable. If the issue persists the microUSB connection on the TP could have issues.

Oh, nice! turning off the USB debugging made the trick. Thank you so much.

The laptop USB ports are good and I've tried using it with my pendrive. Thanks for your help though. =)
Hi all. I'm running Android 4.4.2 with Sense 6 on InsertCoin - S-OFF. It's been fine for about a full year now - I havent touched ROM/firmware in about 6 months. Just this past week, the device is no longer recognizing any PC connections - it still charges fine with any USB plug, but seems to think every connection is an AC charger. Nothing pops up on my phone or the computer (mac or PC). I have USB debugging on.
ADB does not see the device, in normal boot or in Fastboot.
Fastboot on the phone says "Fastboot AC" where it used to say "Fastboot USB"
Is this a software issue I can rectify from the phone? I have TWRP and root, so I can perform certain things on the device itself. Or should I go to T-Mobile and try to get a replacement (I have insurance on the device)

Are you sure you are using a usb data cable and not only a usb charging cable? Usb data cable have 5V+, Ground, Data+ and Data- connections. Charging cable only have 5V+ and Ground connection and will not be able to communicate with the device. You can test your capble on another device to confirm the cable have data capabilities (using a camera for example or any other device with a micro usb port).
Even if you are sure that you are using a data usb cable, you might want to try another one, maybe that one you are using is defective.

Thanks - yes, I tested this on my Nexus 7 too. All 3 cables I tried connect the N7 to both the Mac and PC fine, I was able to flash an OTA to it. However, the same 3 cables product no results for the HTC One M7.

it doenst sounds good, maybe a defective usb port on your phone... Maybe some dirt inside? Try to clean your port with a cotton swab and Isopropyl alcohol
Hi
Just plugged my Android 12 Samsung S21U into my Windows 11 PC but nothing showed on the PC. I woke the phone and tapped on the "charging" notification but nothing happened.
Went to developer settings and set the Default USB Config (which was off) to "Transfer Files"
Set USB debugging to be on too.
Still no avail.
Any help?
Is dex working? Or maybe a driver issue?
I've just installed Dex.
Samsung said I should make sure the phone is in the correct MTP when using the dialpad to type in *#0808# - which it is.
Tried installing the drivers from the Samsung website (although the UK version of the site doesn't offer any drivers) - not working.
I can connect the phone using the "link to Windows" but this won't let me connect normally.
Both Windows and the phone are fully up to date with all the latest.
Just restarted the phone and can connect to Dex, although I think it's doing it wirelessly rather than through the cable.
Yes, have tried another PC (another W11 PC).
Yes, have tried another cable (both high speed purple and low speed).
Yes, have tried another phone on both PCs and that shows fine.
What worries me a little is that Device Manager doesn't show anything connected to the PC when I connect the phone.
Turns out you need the official Samsung cable, which is USB-C to USB-C only.
My PC doesn't have a USB-C connector so looks like I'm gonna have to purchase one.
Shame they've gone the Apple route - my old Huawei P30 Pro will connect for data transfer using any old cable, of which we have loads around these days.

Pretty sure this is false. My S21U gets recognized on my PC with a normal USB A to USB C cable.
Agreed. That is just not true, I've used a USB A to C worked fine
Hmm, maybe my three cables I tried are too old?
They're from Amazon and don't particularly state they work with Samsung phones.
The plot thickens.
It looks like USB-C port of my S10e is faulty. It charge phone, but not transfer any data. I tried 4 different cables. PC wont recognize connected phone, Odin shows empty ports, settings in device has USB settings grayed out. Even after factory reset.
So I guess there is no way to flash different recovery without working data on USB port?

Have you tried on other USB ports on the computer?

Sure.
Then I don't know. Maybe take the phone in for service? Is Developer mode on? Is USB debugging enabled? When you connect your phone and PC, it should ask you to approve the connection. If he doesn't look for it, I think he should look for it. I did it a long time ago, so I don't remember very well.

Sell it to someone who does not need data transfer via USB would be more cost effective. Repairing USB port on S10e is ridiculously expensive.
