Please Help! USB sync not working

New user here at XDA-Developers and looking forward to enhancing my Touch Pro (Sprint) experience.
I have a frustrating issue! I am unable to sync my Touch Pro with my computer
Before you think "Oh boy, another problem this person can fix with common sense or a search" - I'll tell you I tried everything and searched everywhere! When connected via USB, the device is getting a charge (Plugged-in icon plus white charging light flashing on center button) but my computer does not have that USB connected sound that you get when a USB device is plugged in. Nothing shows in device manager and nothing is recognized in WMDC either.
Here's what I have done so far:
* Uninstalled WMDC and reinstalled from the Microsoft website
* Soft-reset my phone (multiple times)
* Rebooted the computer (multiple times)
* Unchecked 'Enable advanced network functionality' in the USB to PC section. Note: 'ActiveSync' is checked. I did toggle between that and 'Disc Drive'
* On my phone, I unchecked and rechecked the 'Synchronize all PCs using this connection' under ActiveSync>Connections... (USB Selected of course)
* Removed the partnership from both my computer and the phone
* Attempted to connect via 'Internet Sharing' on the phone using USB. Received error 67 and then I rebooted the phone.
* The phone does connect to my friend's laptop via Bluetooth - so Bluetooth sync appears to be working.
* I have NOT done a hard reset. I am reluctant to do this since i can't sync to back up my data (I do not have Bluetooth-equipped computers)
* I do have an HTC Mogul and it DID CONNECT using the same USB port and USB cable.
* The phone is not recognized on two other machines I connected it to.
Due to the last two items, it has to an issue with the phone and not the cable or computer.
I am using Windows 7 Ultimate 64-bit (We have a MSDN subscription) but I had this issue before upgrading from Vista Ultimate 64-bit OS. Note: Windows 7 does appear to use the same WMDC as Vista (6.1.6965)
Please help! Thank you.
Update: I did a hard reset and it still did not connect. Sprint ended up replacing the device under an extended warranty for defective USB data connection.

Ok, on my friens phone it was a broken Phone USB port. Same behavior as ur phone.
For the hardreset, get yourself pimbackup(contacts and appointments) or sbp backup (if all has incl software has to be saved) and save all ur data on the flash card. Then try hardreset.

Right, it smells like the USB port in your phone might be defective when you don't get the USB recognized sound on your PC. Take it back to Sprint.
Regards,
Carty..

Thanks for the advice. I am really hoping that it's not a defective USB port since I'm just out of warranty (I do have insurance though). It looks like my only option now may be the hard reset. Since I can backup on my friends's PC all my ActiveSync items (calendar, contacts, etc), I may not need SPB or pimbackup. I need to back up my texts and settings though.. I hear Sprite Backup is good for this.

What was your outcome because I have the same problem.......

If you do alot of searching here, ppcgeeks and howardsforum...alot of the usb is malfunctioning on the TP. Mine just stopped working one day. That was a month ago. And i tried all the "fixes" nothing worked.
*uncheck advanced start/setting/connections/usb to pc uncheck advance network
*Start/program/internet sharing: pc connection USB and connect
*open it up and check if anything is unplugged
*clean the usb port with qtip
*try different OEM 11pin data cables
*uninstall/install WMDC, yep i have win7- which worked great at one point
*last but not least...hard reset....
Only the usb connection doesn't work. It charges via usb. Video out works. And headset works. Sync with xp a no go.
My pc (win7), work pc (xp), home pc (xp) and umpc (vista)- it wil not recognize....
So I use a micro sd card reader to install apps (cabs) and pics to my pc/ppc.
And also use this useful app via wifi too, WIFI Remote Access 1.0 Beta 5 released
it is free since it is in beta...but very useful...

I am in the same boat as you.....I have tried multiple computers, hard-resets, flashed from SD card a few times but suddenly it will not work anymore. This is ridiculous. I am pursuing a new, different phone since I cannot sync it anymore. I shouldn't have to take the card out, put it in a reader and do things like that. I have spent hours and hours on a fix but nothing has worked. I am at a loss....

[Q] USB Device not recognized / Unknown Device

I'm having an issue where my thunderbolt is not recognized by my PC any longer. I used to have it set up with pdanet and everything worked well for about a week. All of a sudden, any computer i tried to plug the device into, wouldn't detect the phone. A friend of mine has tried his thunderbolt on my computer and it detects it.
When plugging my phone in, it pops up an error message with "USB Device not Recognized." In the device manager, the phone shows up as Unknown Device. I have tried this on 3 different pc's, using 3 different data cables. No USB symbol displays on the taskbar of the phone when I plug it in, however, it does charge.
What I have tried:
Changing data cables.
Using another PC.
Uninstalling device drivers and letting windows re-detect and install.
Downloaded HTC Sync and ran it after uninstalling drivers again and re-plugging the phone.
Changed different Connection settings on the phone, such as USB Debuggin on/off, and changing it to HTC Sync Mode, Charge Only, Disk Drive, etc
Mounted and unmounted SD Card in the phone settings.
OS: Windows 7 x64
Is there anyone out there that can help?
Thank you for any information you may provide.

I remember that one of my friend's desire cannot be detected by the pc before, he search the forum and find out that he need to change something in the driver files before installing the driver. I'm not sure if that will work in your case thought..

[Q] Connect as Disk Drive Troubleshooting

I was using my Inspire 4G with the newest release of the MIUI ROM, and it would have issues going in and one of car mode so I flashed to the Android Revolution ROM, didn't like it, and decided to flash completely back to stock thinking that would solve the car mode issue.
After flashing back to stock, I attempted to root again but my phone was not being recognized as a disk drive.
I did the usual software-side things on the device itself, including:
Checking the Default connection type
Enabling Ask me (Ask me about USB connection type whenever I connect my phone to a PC)
Trying with USB debugging on and off
Turning off Fast boot
Unmounting/mounting SD card
Trying a different SD card
Did a Factory reset of the device
I then tried installing/reinstalling HTC Sync on my Windows 7 64-bit PC multiple times. I made sure to disable Windows Firewall and any anti-virus software.
I tried the in-box HTC USB cable on all 3 USB ports, and then tried a Seidio brand USB cable on all 3 USB ports to no avail.
Lastly, I connected a friend's stock HTC Inspire 4G to my laptop, using my HTC USB cable, and my laptop recognized it immediately and I could access the SD card files.
Thinking it was a hardware issue, I took my phone into a local repair shop and they diagnosed corrosion on the board due to moisture damage. I paid $150 to have it fixed.
I picked up my phone yesterday and it is still having the same issues.
I've been using an HTC Aria in the mean time and that connects to my PC no problem and I'm able to view the files on the SD card on my PC.
Does anyone have any other thoughts to what the problem could be before I take it back to the repair shop?
Perhaps it is the software? Is there a way I can root my phone without having the ability to connect it to my PC?
Thanks in advance!

[Q] Nexus 5 not connecting to computer (usb), does not show in device manager

Hi,
I would like to see if I can get anyones assistance with solving my problem. I have lost the ability to connect my Nexus 5 to my computer via USB. I had previously been able to connect the phone without any problems.
Connecting my phone to PC charges the phone but no drivers are loaded, nothing changes in device manager and I cannot see a change in windows explorer to view the memory card.
So far I have tried the following:
searches on various sites
rebooting phone, starting in safe mode, wiping all data, performing a hard reset
connecting other phones to usb cable to check that it is not a charge only cable, also trying several other USB cables
connecting phone to other computers
connecting other phones (HTC) to load drivers (then uninstalling drivers)
displaying all hidden devices in device manager and removing all drivers that resemble something to do with mobile phones
uninstalling programs I no longer require on the PC
using "wugs nexus root toolkit" to uninstall and re-install drivers
checking & unchecking MTP, PTP, developer options, USB debugging in various combinations to elicit a response from the computer.
I have also tried to visually check the connections of the USB port on the phone wondering is there is a break but I cannot see very well.
does anyone have any further suggestions to get this phone connected to a PC?
my only last thought is to attempt to open the phone and check the resistance of the plug connections.

Have you tried enabling and disabling usb debugging while plugged in?

Are you sure you're using a data usb cable and the usb port is good?

Same Issue
same thing happened to me today when i connected the device to PC.
Mine says unknown device on PC under other devices. so i hope my USB port is ok.but im not using the original SUB cable. i wonder that's is the issue. but it didn't bother me until today. my original cable is at my friend's house.
Tried updating drivers manually. But following error message occurs once i select the drivers folder and hit ok.
Windows was unable to install your unknown device
Please help.

so, not really a solution but while at work my phone fell on to a nice rock cracking the screen. I have replaced the phone and the new phone connects to the pc fine, drivers come up without a problem (I will put this down to a fault with the phone)
Thank you for your assistance

No usb connection between HTC 11U and windows

when i connect my HTC U11 to my PC windows 10, no USB activity initiates, i can't use ATP, MTP or mass storage to transfer data between my phone and the PC, only my phone gets charged, and no any pop up message shown on my pc or my phone, and there is no USB status or option on my phone shows there is an active USB connection, also on my PC the device manager doesn't show there is a connected phone at all.
please let avoid ordinary precautions, as i am using new original USB data cable with high speed, i have reinstalled HTC sync manager, and restarted both PC and HTC, all drivers are updated.
i tried to connect another HTC 10 and Samsung note 4, and both are working on the same cable and same windows with a same USB port.
i doubt there is something with advanced options, as i tried 1 month ago to make USB tethering and tried to create entire iso image of the internal memory.
i tried the 3 phones on another computer and gives me the same results, all phone worked and recognized except for HTC U11.
is the USB port in my HTC U11 is broken?
please help
