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.

mine is doing the same thing.
im in the process of a warranty replacement........does it from stock rom all the way to cogb2.3
i have diamond from altell,....i can charging with my cable usb, but i cannot use it for upgrade ROM,....i know this is usb connector problem because i cant even syncronise my diamond with my pc with activesync.
is there any way to upgrade rom/unlock this diamond without usb cable ??? pls help me
If you are trying to install a custom ROM you are out of luck as the SPL unlocker requires a custom SPL afaik. If you are trying to update an official ROM you can just get the .nbh file and rename it as DIAMIMG.NBH in the root of your SD card and hold Vol down and Back key (I think) while turning the phone on until you see the tricolor recovery screen.
One thing to check is to use a different cable. Some cables are charge only and do not carry data signal, or the one you have is bad. Check device manager to see if the PC sees the device at all.

Is there any chance you used a dock charger with your phone? Mine did the same thing you described (checked cables/USB ports/computers and it is indeed the USB port on the phone), and the only thing I can figure is I used a USB dock for a while with my phone. The phone would connect via USB without any trouble before using the dock, but sometime after using it, I noticed the USB stopped working.
Just curious...
Hi.

When i connect the USB cable to Xperia Z and PC, nothing happens at all. NOTHING AT ALL. I need to reset my phone and do some other stuff via usb. Can any on please figure out whats the problem is? If it's some software issue or hardware problem??

it's software problem .. I think you should download SEUS and reflash your rom , btw there are only charging cables.. are you sure that this cable isn't only charging..

I dint get what you are saying?? I tried many other carging cables, Every cable CHARGES but it does'nt work as USB cable. And If i cant connect my xperia z to computer how am i suppose to reflash my rom ??
Hello. I don't mean to sound rude but if you're saying you search can't connect USB and didn't find anything, I think maybe try to re-phrase your search terms. Try some of these http://forum.xda-developers.com/sitesearch.php?q=can't connect with usb
Also, cover the basics. Have you deleted any system apps. Tried USB Debugging Mode. What OS ?
Does it even attempt to install drivers, what does the device manager say ?
What does it do when you connect in flash mode, what about fastboot mode. I had an awful time making my Samsung galaxy s3 to connect via USB to my Mac, I would use my SD Card when installing roms, when I started playing with different ones, I learned real quick that some Roms worked flawlessly, some with some help, some roms wouldn't connect to USB at all. Although that was never the case with my XZ, once it installed the fastboot and fastmode drivers for Windows 7, it's never had an issue, I can't really remember before then.
Also wiggle the card and the connection around see if it quits charging. Those are a few things to try, good luck

I mean that there are cables made only for charging .. not for PC .. the cheap ones with the wall chargers.. they are only charging cable.. not data

Hi
I had exactly the same problem, phone can charge, but can't connect to PC (and doesn't charge from PC as well) .
Factory reset helped to resolve it.

No usb detection at ALL!
Hello,
I have a weird problem with my phone. It's been 3 days and I've tried everything that came to my mind!
First, the phone (Xperia Z3 Compact) was ok, then I noticed I'm low on battery (about 3%), I tried to charge it, connected to charger via micro usb port. Nothing happened, (like it has never been attached at all!) I did it several times, tested the charger and cable on other phones, worked properly on them.
then I tested with several chargers and cables, and tried to charge it with my laptop, even when connecting to the laptop (on Windows), it's like nothing even detected, nothing at all, and on the phone nothing changes (no charging, no data connection, etc.).
Then I tried to restart the OS to see if it solves the problem, but due to the battery-low situation, I couldn't boot it back on! (the battery icon kept coming on the screen). The thing is, on the state before initiating to load the OS (Only the battery icon, big(!) on the screen), it SEEMED to be charging (the charger LED turned on and connecting and disconnecting the cable made difference!). but everytime after several seconds, the SONY logo appeared, and then the smaller battery icon with a 1% text appeared, then the LED turned off and it seemed to be not charging. (I tried it several times, even with 3-vibrate resets, etc. no change)
But when I tried to load it in the Fastboot mode or Flash mode, my laptop detected it without problem. (And did some getvar commands via fastboot, no problem in that state). then I provided a magnetic charger, and charged the phone without problem with that to 100%. But still, in the Android OS, USB does not work at all, no charging via usb, no data mode, no usb detection AT ALL.
Long story short, I even tried these:
Resetting completely to factory settings,
Wiping cache partition,
Flashing (via flashtool) the stock ROM.
and I even flashed the phone with a third party ROM! Still no usb charging/detection! The USB only works in Flash and Fastboot mode!
What do I do?!
I got a wierd one. I got a new work laptop (8.1 old one was 7), and when I connect via usb it goes into some rapid loop of connected/disconnected a couple of times a second
I have pc companion installed, and went and manually installed the flashtool drivers for it also, no difference.

Interestingly, for me it doesn't work with the original Sony cable at my private laptop (Windows 8.1), but it does work with another USB cable at my work laptop (Windows 7).
Hmm, so a different cable did it for you. On mine I moved the cable to another port in the opposite side of the laptop, and it worked fine. I didn't think of trying a different cable. I haven't been game to re-try on the other port.
ok so here's my case:
phone charges well if connected to a chargher-only adapter through USB and charges correctly in it's Sony-socket
phone is not detected by the operating system and I tested it using 2 different cables (that I previously used succesgflly) with: three different PCs, 2 having windows 8.1 (nothing showing up in device manager), one having linux (tried lsusb with the phone connected and disconnected: same output) but...
Phone light's goes blue if I try to start in fastboot mode while connected to a PC (which of course doesn't happen when disconnected or connected to a charger).
I'd like to bring it to service (after trying a hard reset) but I need to backup my data and no idea on how to that without installing a recovery firmware (device is not rooted)
any idea?
Forgot to mention: when I plug the usb club, the experia makes the detection sound.
PS: in the past the USB detection when connected to a PC was faulty, acting like the cable was connected and disconnected continuosly. Previously the connection was working fine.
thanks!
Alessandro
Was anyone able to solve this problem?
My Sony Xperia Z C6603 isn't recognized by any windows PC,
from windows 7, 8, 8.1 to 10. The phone lights up showing it has been connected but the PC won't recognize it.
When i connect it to a charger, it charges just fine.
I have tried Turning n USB debugging ON and OFF, resetting the phone,nothing seems to work.
Any help?
You can try using flashtool to flash a stock FTF
You would use fastboot mode.
You can try a linux live session too to rule out windows
It may be your bios settings
It may be the cable, cables break all the time, get a new one.
HELP.

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
So I seem to have a very weird issue with the USB connection on my Sony Xperia XZ2 running Android 8.0.0 with the build version 51.1.A.11.51. It refuses to connect or charge on almost any computer. The phone doesn't seem to recognize that it's connected to a computer. The computer doesn't see that my phone is connected either. I tried different USB ports, different computers, and different cables and they all won't connect to the phone. The exception is my laptop, which has a dedicated fast-charging port. When I connect my phone to that port, the phone charges, but it doesn't recognize that it's connected to my laptop and the laptop doesn't see a device connected either. Enabling ADB on my phone doesn't seem to do anything.
The strange thing is that almost all other USB functionality works fine on my phone. The phone charges fine from both a normal power brick and a fast charging brick. Both analog and digital based audio adapter dongles works perfectly fine too. USB based Android Auto does not seem to work, but it still charges the phone when I connect my phone to the car.
I also noticed that if I plug my phone into a computer while the phone is off, it would briefly wake up to the Sony logo and have the charging light come on for a few seconds until the screen changes to the battery percentage. Booting up my phone while plugged in doesn't seem to fix the issue.
The bootloader is locked and it has the stock recovery, so I don't think fastboot works (but I'm willing to try if it fixes the issue).
I've already tried spraying electrical contact cleaner into the USB port and also tried cleaning the port with a small plastic zip tie. I don't know how long my phone has been like that since it's been over a month since I last connected it to my computer. I don't know anything else I could do besides resetting the firmware, doing a firmware update, or sending in my phone to Sony for repairs. If anyone has any suggestions, I'm willing to try it.
