USB doesn't work???

Can someone please help? I just bought a used P3300 from ebay (a wholesaler). The phone works great, absolutely everything works except for the activesync over USB. The phone is not even seen by the computer with or without activesync. I have tried it on several computers with the same issue, yet the battery charges through the USB cable.
I even reflashed the ROM using the SD card method and still have the same issue. What might be going on here??? How can the USB data connection be not working? I've never experienced this with many different phones I've had.
thanks,

Go to Settings, Connections, USB to PC, and untick Enable advanced network functionality.

I tried that, it didn't make a difference. I also tried both Activesync 4.5 and 4.2. Still nothing. I hard reset and soft reset several times - still nothing.

What Firewall is on your PC. Could be this causing the hassle.

Have you tried using a known-working usb lead?

I had this problem also to begin with, google an application called "USBKILLER" and put this .CAB onto your memory card and load this onto the phone.
When your in the application select SERIAL and click YES and this should resolve your problem - I am not sure why this happend but my mate who has the same phone does not have this problem and can resolve it by removing the check box in USB to PC settings

hey guys.... thanks for the input. My firewall is disabled - I read the Microsoft article regarding the ports Activesync uses. But AS works with my other phones, so I know that's not the problem. Same thing with the USB cable. It works with the other phones but not this one.
nicko666, I will try that USBkiller program later tonight. Thank you for the suggestion. I'll let everyone know how it goes.

Found USBkiller Cab File Attached - good luck

I tired the USBkiller program (found it myself earlier) but it also doesn't make a difference. I tried changing the setting to SERIAL in the program and also playing with the "advanced network functionality" and activesync connection settings and it's a no-go.
Still nothing works. Do I have a broken device?

hardware problem
i had the same problem after 1 month of using my p3600 i pay 59 euro to change it because the garanty not include this problem.the service told me that it was my fault !!!!

Hello. Is your PPC detected by Windows in the manager of peripheral? It is necessary that you look at if you have a new network card named "Windows Mobile".

I had that problem. I am sorry, but I think you bought a used and not-functional phone. The problem is probably due to high power that the phone got, probably when charging it through a car-charger. You should NEVER connect the phone to a car charger and then start the car - the power can damage the USB connection. You should always first start the engine and only then connect the phone to the charger.
Anyway, I had the same problem - the USB could charge the phone, but no Active Sync connection. I sent my phone to HTC UK, and after one week I got it back with a new board (they replaced the whole inside of the phone). Free of charge.
If this is the situation with your phone - no software solution will help you.

Damn, that sounds like what's going on with my phone. How do I find out how to have it serviced? I can't find anything on the useless HTC site. Please help....
And thanks to you all for the help so far.

I remember sending them mail regarding the problem, via HTC site (mail: [email protected]).
After all the solutions they suggested didn't work, they called me and asked me to send the phone to the UK (they gave me all the details and were very nice and efficient). I must say that my phone was still at warranty period.

this may sound silly, but have you tried the usb ports on the back of the computer?
for some reason, the usb headers on my motherboard don't seem to recongise the phone, i'm not sure if theres no enough power or what, i've onbly tried the cable in a laptop and that works fine...if i plug them in the front usb ports i get the error in windows 'Your device has malfunctioned, Replace the Device and Try Again' or something very simular, tried the other usb header on the board, same problem, back ports, no problem...all other usb devices work fine in all the ports!

Dear all.
I work for a company that has over 600 of the htc p3300. Some of them will work in the usb and some don't.
I have 4 at the moment, 2 of them will work with the usb and the other 2 won't........
Tries all the stuff mentioned here and nothing helps.
Can't update them because of the usb........
HTC are not a lot of help either......

Hi I had been trying to sort this problem out too, and after reading about starting cars with the device on charge I thought I was doomed. But what stead suggests has just worked for me too. I was using the nearest USB on my laptop but plugin it in round the back has just got it working again. The last time it synced it was 'Repairing' the Active Sync 4.5 setup program run through. I must admit that the cable into the phone is also resting on a pen at the base of the phone- just to make sure....

computer problem!

i'm not sure if this is the right section to ask this but my tilt 2 is not recognized by my computer anymore. I thought maybe it is the phone but it's recognized on other computers so I was wondering is there a way to reinstall the driver on my computer or some other fix someone know of?
I think I saw some threads with similar problems but I didn't see any definitive answer in any.
HELP PLEASE!!!!!!!!!!!!

Do you have XP or Vista/7? The first step you should try is uninstalling/reinstalling whichevery type of sync software you have on the PC...for XP it's ActiveSync, for Vista/7, it's Mobile Device Center. A fresh reinstall of those sometimes clears this problem up, and it's the easiest solution to try first

I have xp and I have uninstalled and reinstalled but that doesn't do anything my phone still isn't recognize that's why I was wondering if after u uninstall does the driver remains on the hard drive and if so how would u remove the driver so u can reinstall it.

Do you use the same cable when you are connecting it to the other computers? If you do then... well I dont know.. I would still try a new cable and wiggle it a bit
When you uninstall the Active Sync I believe it does take the driver off as well...
When you connect your phone to the computer does it still come up asking if you want to connect via Active Sync, Disk Drive, Internet Sharing?

I'll give you one method that helped me at least when I was having connection issues, have no idea if it is related to yours (and it might not even be applicable to the older XP version of ActiveSync).
While your phone is connected, go into Device Manager and under the Network adapters node, look for "Microsoft Windows Mobile Remote Adapter". If it is there, uninstall it.
After that, disconnect then reconnect your phone.
As a long shot, you would not happen to be running any VPN software would you? A connected VPN always makes syncing the phone impossible.

Is your phone charging while connected?
I had/have a USB connection issue with my Tilt2. It wasn't recognized by the computer, but it was charging. When I connect through bluetooth, it is detected just fine. I am assuming that my issue are the pins in the USB connector on the phone, since I have the same issue with different cables.

yeah it's still charging but that is it... nothing else happens

Every so often when I connect my phone to my pc all it does is charge.. All I do to fix it is soft reset the phone AND restart the computer. Usually after that it works fine. If not just take it off and put it back on the dock or cable.. if you try a different cable that might work for you too. Or try plugging your cable into a different usb port on the computer

PC Connection Issues with EVO

Already tried reformatting Windows and installing any and all drivers I could find.
When I connect my EVO to my PC via the USB cable, the connection type window appears, the amber light turns on, and it shows up on my PC for ~2 seconds. Then it disappears. I have been unable to keep it connected.
It works on other PCs I've tried, just not mine for some odd reason. (Any other USB item works fine), and I've tried multiple USB ports.
Any ideas?

I had this exact issue when I was going through a non-powered USB hub. As soon as I plugged it into my computer's direct USB plug no issues. How old is the computer you are trying to plug this into? Is is USB 2.0? I'm on windows 7 64bit if that helps. Hope you get this fixed, it's annoying as hell.

Forgot to mention, this is on Windows 7 x64 as well.
Im using the ports on my mobo, and its a rather new mobo (XFX 780i). Tried every single port =\

[Q] Cannot install Windows 7 64 bit Drivers

I've tried everything I can possibly think of. I have an Asus Laptop with Windows 7 64 bit and absolutely cannot get my Epic to be recognized. I've uninstalled and re-installed the driver more times than I care to mention. I've tried mounting the device to no avail either. I've tried plugging in the phone into each of the USB ports on the laptop to no avail. I need to get the computer to recognize the device so I can get odin to recognize the phone so I can flash back to stock. Right now it doesn't do so. Does anyone have any ideas of what I can do to get this up an running?

Try installing the 32-bit drivers even if you're on a 64-bit computer....

The same issue comes up. It says that the drivers are not successfully installed (even though the installer goes through) and it says "Unknown Device" over and over.

Are you removing previous drivers?
then rebooting before installing new drivers...
also are you using stock cable?
if so buy a new cable you can get cheap ones online for like a dollar just search micro usb cables

Yes, yes, yes. Does the cable really make that much of a difference? I saw that people have had issues but I mean it charges properly all the time so I figured it was ok to use.

Absolutely!!!!!!!!!!!!!!!!!!!!!!!!!!!1
That cable is worthless get a Blackberry cable they are very durable and dependable.
i was having problems also..... all because of the cable.

I'll probably go buy a cable from Walmart, order a cheaper one online from Monoprice and return the other just so I can odin my phone...I really hope that's the issue though.

does it keep looping "unknown device" in the corner, almost like you unplugging and plugging back in repeatedly?
ifso try cleaning the contacts of the usb port on phone and on the small end of the cable.
if not then try totally uninstalling the drivers you installed and if possible when its saying "unknown device" open the device manager, r-click then unistall in there.
USBDview has always been able to dig me out of the home when ive had usb related driver issues... just run it and delete/uninstall anything samsung/android/adb etc related, reboot pc and phone then try again...maybe even redownload the drivers

update (you replied as i was typing): one bandaid for the cable you could try for now is to take a needlenose pliers or something and slightly squish the micro end to try getting a tighter fit.... i had to do that to the cable i keep at work.

You can always just download kies. That's what I did. When I was trying the standalone drivers I had trouble. Installed kies on both of my laptops and coding works beautifully everytime. And I seriously think you guys are ill. Its a cable... its digital. It either works or.it doesn't. I use my samsung wire exclusively. Its thin and I like contour on the plug. Both cables have worked flawlessly on both of my epics.

You are wrong.
Cables can have breaks in them which give them intermittent connectivity. Also, since this cable has several (5 I think?) single strands of wire in them, a single wire could be screwed up causing this (or the pin for a single wire on either end) That would still allow it to charge, and partially be recognized by Windows, but not allow it to fully communicate causing this problem.
I have a cable that I only use for charging because it has this EXACT problem. Another cable works perfect, but this particular cable gives me the unknown device.

Right.. so it either works or it doesn't lol if both cables are in perfect working condition then there would be no issue. Its all preference. I personally use a blackberry micro usb cable. It locks in to the usb port on the phone better. Just so im not paranoid about the wire coming off while flashing... cuz thats bad lol

I didn't articulate myself clearly, but that is my fault.
If a single wire inside the cable is broken (for the sake of simplicity let's just say it is the RECEIVE cable - from the device to the PC). The PC can recognize that there is a device there, but because the device can't talk to the PC, Windows can tell there is something there, but has no idea what it is since the device can't talk back to the PC. Also, in this scenario the cable would charge just fine since those individual lines are intact.

To quote u "Yes yes yes" it does make ALL THE DIFFERENCE... I had the same problem and made serveral posts about it when the phone 1st came out, I tried everything... Uninstalled/Reinstalled/Rebooted many times, Manually deleted the folders where the drivers are held then Re-installed, Installed Kies (which is a P.O.S. and was a BIG WASTE OF TIME imo.) I tried everything and just about gave up until 1 day i looked @ my roomate and asked him 2 let me borrow his cable to his cheap cricket phone 2 see if it would make a difference.
Well it worked... Get a new cable, if you've done what ive done and it still doesnt work, its the cable and not the drivers

I've done just about all I freaking can on this as well.
I've installed, un-installed, and re-installed the drivers. I'm running Windows 7 64 bit on Bootcamp.
I've used USBDView, I've uninstalled all of the connected drivers. They get re-installed, but the phone keeps keeps coming up as an Unknown Device. I try and locate the Samsung USB drivers directory, but it keeps coming up as Unknown.
Does anyone know specifically what directory I should use choose when trying to manually link the driver in Device Manager? I'm having a ***** of a time here.

Anybody have any ideas for me? Thanks.

I had the same problem. Buy a new cable from monoprice. The second I bought a new cable for my 64 bit Asus laptop it worked.
Trust me, buy a new cable.

I had the same problem. I didn't follow directions to solve my problem in Odin. I had to start Odin and plug my phone in and quickly put the phone into download mode. I did that a few times and finally got it to recognize. With Syndicate, it now recognizes every time. I say that now. LOL

This is how I fixed this problem. After doing all I could think of, uninstall, install, system restore, nandroid restor to when phone was being recognized... all these didn't work for me. I still got the same unknown device in device manager.
The fix: with samsung epic drivers already installed. Turn the phone on, plug into your computer. Let device manager find unknown device. Power off the phone. Boot into recovery. Pc will recognize your phone as samsung android device. Reboot your phone and you should be good to go. Hope this works for the rest of you. Good luck.

Isn't the original issue that the driver install fails? not that the device isnt being readed?

USB transfer not working

Hey guys, just wondering if anyone had this before:
I am able to charge the devices, but nothing related to USB transfer works...
I am stock, not rooted, with latest version available for the Telus' E973
I've tryed 3 PCs, 2 cables, hard resetted the thing but nothing...
So far, I'm thinking I'd RMA the thing...

Does phone ask about mode when you plug it in?
Also, does the computer make any sound or showing that it's plugged in under computer or device manager?

Sounds like USB cable problem, but if you tried 2 cables the odd it's the problem are really low.
Sent from my Galaxy Nexus using xda premium

Nothing on either the computer nor the device, no changes in the device manager...

Was having same problem.
Redownload/install the ADB drivers or whatever they are, and all other drivers. Worked for me. Mainly the ADB ones.

You mean on a computer or on the device?
I've tried on multiple computer which were working before, and nothing is being "added" when pluging in the device, so it's most likely not a driver issu on the computers.

Maybe you broke the connector? What os does the pc have

Tried with Windows 7 x64 and x86 and Windows XP, same thing on 3 PC's
No reaction either on the PC's or the device.

Definitely broken connector

I'll keep you posted, I'm going to check out with my reseller tonight or mid-day.
So far, I understand that no one had this issue?
Thanks for all the input!

Got there during lunch, it's send out...
Now I'm stuck with a crappy Desire HD...
