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....

Unable to connect phone to computer

Hi everyone
For the last couple of days I've been having trouble with getting my computer to recognize my phone. When I connect it, the usual red/orange LED starts glowing, but there's no reaction from the computer. Neither does the phone show any signs of having connected. The usual "choose which connection type you want box" doesn't pop up, and there really aren't any signs of having connected, other than the charging LED.
I've tried reinstalling Windows Mobile Device Center, tried switching cables, I've checked the connection settings on the phone, but can't find any irregularities there, so I'm a bit lost here. Do you have any thoughts?
For the record, I have a Rhod100 and I'm using Win7 64-bit, as well as Ubuntu 10.04 64-bit.

Have you unchecked the faster connection?
Start > Settings > Connections > USB to PC. Uncheck the enable faster connection. My win7x64 didn't wanna connect until I did that.

By "the faster connection" you mean the Storage Card mode right? If that's what you mean, then yes, I have unchecked it.
I have chosen the ActiveSync option, and have also enabled the option to always ask which connection type I want upon connection, however the box never pops up :/
Thanks for your reply

Activesync is the one that uses faster data sync, not storage card.
I know that the USB has a problem of going out for some people, so it could be an issue with that....have you tried to connect via bluetooth??

If the box isn't popping up, there is a problem with the USB connection try a different cable; if that doesn't work, take a magnifying glass and examine the phone USB connector - them may be some bent pins in the connector. If so, GENTLY straighten them out.

ActiveSync is picky anyways even if you have a good usb connection. On my xp compuer, if I want to connect without doing the setup (which I usually do, if I dont then it forces a push email account onto my phone if I sync), I have to hit the connect button in the activesync window. It flashes roms flawlessly, but disconnects often while file browsing. On my dads vista pc, it browses files perfectly but I have tried everything possible but cannot flash from it using wmdc. I would definitely try it on a different computer if I were you, your computer might just be acting funny

I just had the same problem and i tried all the fancy things you people are talking about.Its a manufacturing fault and needs warranty replacement of the board.noting else will work.

start the phone up in bootloader mode (powering on the phone with the volume -down pushed). The tricolor screen should come up with the word "serial" in blue in the white area. Then plug in the USB connector,that will tell yuou if your port is really bad. If not it will change "serial" to "USB"
Still if you haven't flashed it then send the thing in now, HTC honors warranties based on serial numbers so you don't have to deal with tmobile, but only if your phone is NOT hardspl'd or flashed with a third party custom ROM

I had the same problem on an htc diamond. It needed to go back and have the board replaced.
The fault is caused by connecting the phone to an in car charger and then starting the engine.
Took a while to happen.

[Q] connect desire z to ubuntu via usb

hey there,
i was searching the web and the forum though couldnt find any issues for connecting the desire z via usb to ubuntu (10.04 for me). however, it doesnt work with my DZ. i bought an addition micro-usb-connector (htc) and the phone does only charge and not ask, what kind of connection i want.
once, i read (and experienced) that you have to connect the usb to the back usb-ports (not the front ones) to get it working - that was with my desktop pc. now, using my laptop, the connection (mounting the sd, tethering or whatever) wont work on neither of the laptop's usb-ports...
so maybe there are two questions/issues:
does anyone have similar issues or maybe no problem with connecting the phone to
1) a laptop?
2) ubuntu 10.04?
thanks for your anwsers!

This might be nothing to do with it, but I found that I couldn't use adb with my phone when I was using a third-party USB cable, even though it sync'd (HTC Sync) fine. This was using XP. When I went back to the original HTC cable, adb worked fine.

Hi there,
I have a laptop with Ubuntu 10.04 (lucid) and everything works fine here. If i connect my DZ with my laptop a menu appears on the DZ asking if i want to charge only, use as disk drive, HTC sync, USB tethering and internet passthrough. I havent tried HTC sync but the rest works fine. I can even synchronize my music with Rythmbox or Banshee. So what i'm saying is that it should work out of the box.
My DZ is stock European edition, no root or s-off yet.
I suggest you first look in the settings of your DZ and look for "Connect to PC". There you should see the settings for the default connection and a "ask me" option. (My default is charge only and "ask me" is turned on). If this doesn't work maybe you can test your device on another computer to see if the menu does appear when you connect your phone.

Thanks for your replies.

I was trying to get adb working but ended up in getting an no-permission-error. Couldn't figure out the problem...

My DZ is also European,standard stock Rom,nothing done (yet). I checked the settings you mentioned and it says "ask me".
Next thing that is really weird: I can enable the tethering option (but cannot use it), yet the connection bypass (or what it is called in English) is greyed out. Tomorrow, I'm going to try the usb cable from the box...

ok, i checked with the original usb cable, still i wont get a connection. as my laptop sits on a docking station, i also tried the back-ports (at the docking station) and un-docked it - no success. none of the three ports will grant me access to the phone.
furthermore, i booted into windows xp and it will show a removable device, but i cannot access it (says something like "enter a device").
it seems to me, that it has something to do with my laptop (lenovo t61) and its usb ports... i have no idea, what to do, so i'm happy about any advice or experience...

Try the guide on adb at http://forum.xda-developers.com/showthread.php?t=865685 , it tells you where to get the Windows drivers.

thanks for the hint, i tried to adb on linux (without success), but going for the windows try...
i'm wondering about, why the phone does not simply give access to the sd-card, like any other removable device. why do i need to install htc sync (including the drivers)? when plugging any removable dev for the first time, it normally just installs the drivers and you'll get access... where is the problem here?

I know what you mean, I would have thought it would "just work" if you connect the phone in "Disk Drive" mode, where the SD card is mounted on the PC.
You're not using a USB hub, right, you've tried connecting straight to your PC's USB ports ?

no, there is no usb-hub used. the connections i tried were always direct ones.

The next thing to do would be to try to connect your phone to another computer. Because it could also be a problem with your phone rather than your usb ports.

well, the phone connects perfectly to my desktop-pc...

It's a long shot, but I did some Googling on "Lenovo T61 usb problem" and saw one report from a guy whose USB didn't work on his T61 with Ubuntu until he upgraded the BIOS

Steviewevie,you are doing my work,you know
Well thanks for the info,do you happen to have a link?
Edit:thinking about that... updating the BIOS??

I only had a quick look, so a more extensive look may well turn up some useful info. The thread I stumbled across was at http://ubuntuforums.org/showthread.php?t=673501

Ok,i took a look at the link (thanks!), but that deals with ubuntu 7.04. To me, it doesn't seem to be the issue that usb ports are not working, as other usb sticks and my touch pro 2 were recognized without any problems.
Imho,it is like when I connect to the front ports of my desktop, when the connection doesn't work either, so I'll have to live with it. Thanks for your support anyway (I'm still open for new approaches)
BTW: it really bugs me that I can't just plug that device and use it as a mass storage like any other...

i have absolutely no idea why, but now it works... today, when i was charging the phone via usb (the thing, that was working from the beginning), my DZ rebooted spontaneously and afterwards it just showed the missed connection options...
no i just need to figure out how to use the internet-forwarding (dont know the correct translation - what i want is to use the internet from my pc on the phone) ... any clues?

HTC M9 Connecting to Computer Problem

Hey Guys,
First of all, I am a new member here my name is Salem and its an amazing forum.
Anyway, I have a slight problem with my HTC M9 while connecting it into my laptop. First, when I connect it, the mobile starts charging, and it gives me no option as to change it to Media Transfer or anything... even it gives me "Slow Charging" Error, and my laptop is detecting nothing, as if nothing happened, nor its searching for any drivers...
I went to developer menu and used USB Debugging, and selected USB configuration as MTP, and it didn't work...
I installed HTC Sync to get the drivers, and it is the same.
Can you guys help me? because I wanna root the phone and I tried various Auto Root applications without using the PC and they didn't work. Thank you guys

No signal from the laptop probably means you have a faulty USB cable. Most likely a break in one of the data wires.
Try another good quality usb 2.0 cable.

Same issue. Tried multiple cables
I have the same issue. When I try to plug into any PC a slow charging message pops up but the phone won't give me the option to connect to PC. I have turned on USB Debugging and selected MTP (Media Transfer Protocol). Please help!
I am with TPG. Android 6.0 HTS 7.0 Software number 3.35.617.12
I only bought this phone a week ago and it updated when I turned it on.

Most likely a crap or broken cable. Other cables, other sockets, other pc's are all worth a try.
You should leave the usb port in "charging only". When you successfully connect to a pc the phone will prompt you to allow data transfers to that computer.
I know this because mine does it. I'm sick to death of the effing thing promting me to connect to my xbox one when all i want to do is charge the effing thing... My phone is set to charging only.
I suppose rom choice will affect it too. Mine is rooted stock 6.0.
Beamed in by telepathy.

Still have same problem
I still can't connect my M9 to my PC. Still have slow charge message come up and no option to connect to PC. My work around has been transferring files using WiFi. However, now I need to do a presentation using scrcpy and will probably have to get a new phone. I'm tmepted not to buy HTC again. Pretty frustrating and no fix found on the internet...

Connecting to PC - not recognised on Win10

Had my A70 since July time, no issues so far, except for now. First time I needed to connect to my PC, Win 10 comes up with the 'WIndows didn't recognise the device' error. Have tried 2 different USB cables thinking it might be that but no different. Then I plugged my partners identical phone into the PC and it recognised it straight away so am assuming that there's no issue with the PC itself in terms of drivers etc. USB configuration/connections settings on both phones are identical, i. e. 'Transferrring files'. Tried Developer options with USB debugging on, I get connection sounds but eventually the error message on the PC. Anyone had similar or any ideas what the issue with my phone might be because i'm stumped?

OK, sussed it. With phone connected to PC I turned it OFF. Then turned it on again still connected. PC recognised something as an ADB device and said I needed to restart the PC, which I did. On restart, Device manager showed a Samsung Mobile USB Composite device connected but still didn't show in Windows Explorer. I disconnected the phone from PC and then plugged it back in again, this time I got a message on the phone asking me if I wanted to allow connections, I pressed 'Allow' and there it was.
Didn't have to do this with my partners phone so have no idea why mine should be any different!
