USB doesn't work???

[chiefsalami]

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:D - 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:confused:

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?

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: callservice@htceurope.com).

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....
