Hi
First of all try to reinstall Microsoft ActiveSync, than in the ActiveSync options, in your device, be sure that in "Connections..." setting "Synchronize all PC by this connection" is checked and below "USB" showed!
Otherwise, if your device, when connected to the PC, also doesn't charge (if you have this option enebled on your PDA!) there is some problem on your PC settings concerning the USB! Try to connect to someother PC to test it!
Ciao

thx...

hello there, first n foremost thanks for your input!
Before trying out your possible solution i tried to connect and for some reason i was able to connect via the device today...??!!
i really dont know why, but will try your soln if this situation reocurrs.
NB: this happenned to me twice in the last 3-4 months, n i never figured out the cause ??
any other advice or ideas gratefully accepted.;

its probably the same as me and loads of other people - the pins have bent on your usb connector - probably caused by using non standard chargers and usb leads. Its been widely reported. The non-standard leads have too much space around them when plugged in and wiggle causing the connector on the tytn II to bend. Try using the lead which came in the box and see if it helps. and try using the charger that came with it too.

Can bent pins be fixed?
Hello -- I'm one of those people with a non-recognition problem. Is it possible to fix the bent pins? My problem seems to have begun around the time I lost my original USB cable. Now, all the cables I have -- ones that have been specifically sold to work with my HTC Tilt -- have the symmetrical, sort-of-trapezoidal mini-usb connection, rather than the rectangle-with-one-corner-cut-off shape of the original cable. I should say these cables do charge my device, but none of my computers recognizes it as a USB device.
Help?
Thank you,
J. Georgia

bent pins continued
I should add that the charging cable that originally came with my phone has the same connector shape, so I'm not sure what's going on.

USB Device not recognised
This is known to happen at times win Windows, and not just for the TYTN2 but a myriad of devices.
The fastest fix for this:
Reboot ur PC/ Laptop.
If this Doesn't help - Then add in a reboot for the TYTN 2 also.
The problem will go away for some time.
I know its annoying, but this is way faster than troubleshooting for contacting MicroShaft Support.

Unfortunately this is no soution for me. I seem to have this problem as well, since about two weeks.
I use two notebooks (Dell & Acer) and both do not show any activity when connecting my Kaiser to the original USB cable. The device is not even switched on when I connect it, nor does this happen when I connect it to the (original) cable in my car, which did work before.
Charging works fine, both in the car and when connected to both notebooks, but no Sync at all.
I have tried another USB-cable with the same result, so I suspect some hardware-problem causing me to be unable to copy files between my notebook and my phone and worse, rendering me unable to flash a new ROM onto it.
Who knows what to do next?

I am mystified, too. USB Charging and audio connections work. I have rebooted my computer and done a soft reset on my phone several times, to no effect. I uninstalled and reinstalled Windows Mobile Device Center. Still nothing at all via USB. Once, yesterday, I somehow got a Bluetooth connection long enough to sync, but haven't been able to since then. Even then, Windows Media and AudibleManager couldn't see the phone. The really weird thing is, I can see the phone connection in my Bluetooth manager, but even with all the proper boxes checked, I can't sync. When I try from my device, I get an empty progress box which disappears after a fraction of a second. When I try from my computer, it says the device is not connected, but doesn't give me any option to connect.
Would a hard reset help?
If so, would returning an unlocked AT&T Tilt to factory defaults lock it back up? And what do I do if it does?
Please help!

I have had similar problems with my touch pro in the past, even bluetooth internet sharing eventually gave up the ghost.
I tried a myriad of leads and then eventually reinstalled active sync- which did the trick.

I've had the same problem with my first Tilt. There's multiple threads that detail this known problem. Some seem to be due to bent pins, some are general hardware failures (possibly the USB controller). There are some HardSPL images out there that have a "force usb" option enabled. This never worked for me, but it might be worth a shot for you.
...a word of warning....
If you end up reflashing your phone (via MicroSD) and the flash goes bad, you may be stuck, as many of the solutions for repairing a bad flash require you to USB sync. My first Tilt was a victim of this after a bad stock ROM flash that left my device without audio, and unable to flash via MicroSD.

replace usb board
you need to replace your usb board. It will run you less than $10 if you do it yourself. you can get the board on ebay

really? 4 years later?

HTC Diamond USB error

Hello everyone,
I'm having a problem with my Diamond. When I attach it to a USB port nothing happens. No 'hardware found sound' or what so ever.
I tried several other pc's with no result. It does charge when it is connected and the phone asks whether it needs to be in USB mass storage mode or in Active sync mode. I havent found anyone with the same problem so I'm afraid it is a hardware failure?
I tried:
-Soft/Hard reset
-Several computers/usb ports
-Disable Advanced Network capabilities
Does anyone have some tips that I haven't tried already that could help me out?
Thanks for your time!!

Disable Advanced Network capabilities under USB->PC in your Settings, that should do it.

I tried that also. With no result yet. Any other tips maybe?

First, check your cable for any marks that resemble rabbit bite marks or alligator bite marks.
No, seriously, check the points where the cable goes into the plugs for any obvious signs of damage, then check the cable itself.
Maybe, try using a different cable, if that doesn't work your Diamond most likely has a problem. If the different cable works, your cable is a goner.
Although I think there's quite a small chance that that's it, it's worth trying, right?

Use the 6.1 version of the Windows Mobile Device Center under Vista

Thx for all the tips. I didn't manage to get it working though
When the phone is connected to the charger it asks if I want to use activesync or usb mass storage. A friend of mine has also a diamond and his doesn't ask this. My conclusion is that it is broken
Damn I got this phone as a replacement for my broken K850i from my provider...They will go crazy when they see me again

Hi,
I have the same problem.
My guess is that it all started with a non compatible charger.
When charging it asked for active sync or disk.
After that the problems started, active sync doesn't work anymore.
Sometimes it workes when advanved networking is off.
Tested on different pc's, freshly installed.
Complete factory settings, notting works.
If synchronised by bluetooth it works.
I'm affraid i have to send the phone back for repairs and trow away the bad charger.

I never used a 3rd party charger.
Is there a way to update the firmware via bluetooth?? Because i'm still using the old slow version...

Same problem here. I've used my tomtom USB car charger. Is this a guarante matter, or do i have to pay for the repair?

You may have set the default connection to other than ActiveSync when first seeing the pop-up.
Go to 'Settings' 'Connections' and select 'USB to PC'.
Ensure ActiveSync is selected.
If you want the pop-up to display when the USB is connected (its good when you want to use your internal micro-SD as a memory stick), check the box at the bottom. You can select ActiveSync, Memory or PC Modem from when it appears on connection but when you just ignore it, it will perform whatever default selection you wanted last and then dissappear.
If all else fails perform a hard reset!

I've tried /soft/hard reset. No luck..
Can this be a hardware related fault, or could a ROM flash resolve the problem?
Transfering video files via BT is a pain in the a*s...

i would try a flash before returning it. You can probably dl an official 1.93.xxx.xx from htc and try that. You don't need hard spl and all that for those ROMs.

I have the same problem:
no connection at all from the PC-side. The Diamond comes up with the ActiveSync/Discdrive question and starts charging, but nothing else.
I did use external chargers that also trigger the ActiveSync/Discdrive question.
Update:
Oops, it seems fixed after a soft reset.

Same problem, diamond would not connect to PC.
Solution: Warranty repair---> they changed the motherboard, and everythings is good. Everything was free.
Edit: But now I have a different problem. I connect diamond in to PC, everything is good, but about 30 seconds after, mobile center looses the diamond, and sync won't work. Any solutions?

I have the same problem before. My Diamond USB cannot be recognised by the PC. Took back to repair and now working. But one PC still cannot recognize the diamond. The service centre told me they have reset my unit and when came back, everything has been cleared. I suspected a full reprogram of the ROM.

I have the same problem
I cant have any connection to the PC
so, no solution but the service people

USB Connection ERROR
I have the same problem. No computer seems to be able to connect to my P3700. I tried DL new ROM but I don`t know where my device came from. On HTC site from HK, which is the only one where I found a neutral Diamond with no carrier associated like, Sprint , Telus, or the like, its says The ROM Code can only be updated on HTC Touch Diamond Hong Kong English Version Device
Does anybody have a clue how to find out where my device was originally intended to be marketed? My ROM is 1.93.456.2 WWE dated July-10-2008? Do the the numbers 456.2 mean anything?
Help is highly appreciated!!

I already did. The first few times the problem occured it worked. I have 6 different USB wires and they all cause the problem. When I hook up my HTC Touch, they all work well!?

Won't sync with PC
Hi,
I have the same thing where it won't sync with any PC and i've tried all the "other" fixes and I've sent it to the service people to have a look.
Thing is, because I thought it was an issue with the usb connector I thought I would have a poke around with it myself and i could see one of the prongs looked like it wasn't making contact. To cut a long story short whilst i was trying to fix it the plastic tab in the mini usb connector came out completely
Service people are now saying that I've abused the handset and want to charge me £70 to fix it. Now to be fair, I have made it worse, but in my defense it was only because a fault had occurred that I started to dabble.
I also reported to the service people that the led light under the "end call" button had stopped working completely. This was definiatley not due to miss use.
I'm wondering if this led is on the motherboard like the usb connector is. If so, can i be cheeky and just ask them to fix the led and not the usb? but by default because the m/b would be swapped out then the usb would be fixed anyway?
If you looked at my phone it looks well cared for (which it was!!!) and its not like I've hammered it in anyway.
Anyone have an opinion or know if the led for end call and the usb port are both on the motherboard?
Thanks

Connection via USB problems

I don't know how it happened but all of a sudden when I connect my Kaiser to my computer via USB cord, it doesn't connect. It charges my phone but it doesn't let me explore my phone. Activesync or Windows Mobile Decive Center do not read my phone.
I don't know if this matters, but when I go into COMM MANAGER (I don't know if I unchecked anything by accident) but the Data Connection tab is turned off and I can't turn it on.
Does anyone have any suggestions on how I can sync my phone again?
I tried a hard reset, i tried a soft reset, i tried different mini USB cords but NOTHING worked...

A couple things.
Under the settings tab there should be an option for " enhanced USB networking". try to enable/ disable this.
Also, it is possible your USB port is no longer functioning properly. A search for USB Problems yields MANY results, some of the fixed include simple things such as reflashing a new rom/radio , to the extremes of having the USB port replaced on the mainboard.
Also, have you tried to sync it to more than just 1 computer? Try on a couple. Make sure your activesync isnt the cause.

Just like pyraxiate said, try toggling the enhanced usb networking opetion. Also give your mini usb port on your phone a visual inspection, its not uncommon for it to crack (mine's cracked before).
If all looks good, restart your computer and soft reset your device. Google for activesync restart, theres 2 or 3 apps that completely kill activesync and restart it. It also wouldn't hurt to check another PC to see isolate the problem.

GOT IT, thanks for your help guys. I went to Settings>Connections>USB to PC and then unchecked 'enable advanced network functionality' and it worked!

Glad to hear this one was a simple one
Have fun here on XDA!

same problem
I have been having problems getting my usb to connect/sync also and thanks for the idea to check for a crack in the mini usb port. I am new to all this, this is my first pocket pc - or even smart phone before Is there an easy way to fix this problem or is a "send back to company" fix only?

horrible problems with my USB cable and diamond

hi,
I think my cable or port on my diamond is a little screwed, active sync stopped working just a week after I got the phone.
I posted the problem here:
http://social.microsoft.com/Forums/...c502e361-e0e4-4d26-9ead-7f2680ff160e/?lc=1033
I got Nothing so far. I did all the active sync troubleshooting I could when I noticed that when I charged my phone, the dialog to choose active sync or disk driver shows up!!? As if i plugged it into a pc, also I do plug is into any ANY pc as a Disk Drive, it doesn't work at all.
IOW.. when I connect my phone to *charge* a dialog shows up asking me whether I want Active Sync or Disk Drive as if i connected it to my PC. Nothing happens after that, and it will not connect to active sync or disk drive to ANY Pc (tried multiple pcs).
What could the problem be? Should I try htc tech support?
Please help, this phone is only a month old!
Thanks so much
Gideon

Ok.....I'm not sure what you're trying to say. What's the message you get on your screen when you connect your phone to the pc via activesync?

I'm sorry, I was freaking out just a little while writing that. I rephrased some of it.
I get the same dialog "Active Sync or Disk Drive" when I connect it to my PC, but nothing happens after that, and it doesn't work on any pc at all. And its driving me nuts, to send a file to my phone from my desktop(my main computer) I have to connect it to my laptop via a lan wire, then send the file over there, and send it from the laptop via WiFi to the phone! ! =X
Oh btw, I've also tried other mini USB cables. Same thing.
Thanks so much
Gideon

What version of activesync are you running? Download the latest version from here. Activesync runs on all OS versions from Win 2000 SP4 upto XP SP3. If you have Vista installed on your machine try this link.
Would you be able to paste a screen shot of the error message and the dialog box?

I use the latest 4.5, but that does'nt seem to be the problem.
It doesn't work as a Disk Drive on ANY computer? There isn't any message or error, on the phone I get the dialog "Connect To Pc" dialog, I choose DISK DRIVE but it doesn'nt work, not on MY pc not on ANY PC!! ='( And just nothing happens.
I've given up on active sync, i've read every post here on xda and elsewhere, I simple can't get it working, I don't have active sync on my pc now. On my laptop with *Vista* however, the windows mobile device center manages to connect and sync with my phone via *bluetooth* only
Thanks so much.
Gideon

Take out the memory card from your phone before connecting it to activesync and try again. Tell me what happens.

You cant take out the diamond's memory, it's build in internal memory m8, not like the touch pro's microsd or anything so he wouldnt be able to try/ do that
I've had active sync problems as well, I normally find it's simply the sh*tti microsoft OS's/ programme's problem & if you re-install or update the active sync prog or windows mobile centre if your using vista, it then see's the diamond again no problems & let's you then set it up correctly, so I'd try all that 1st before you go phoning htc or your carrier to complain m8

Had the exact same problem with my Diamond.
The fix was; return to reseller/change of mainboard in the phone.
A known problem with some Diamonds according to the technician who did the repair.

Humm, I ran into a similar problem with my Diamond when I bought it less then a week ago. Nothing happened when I connected the with the bundled cable though it did work at first. So I took a normal one (from the ps3 controller to be exact) and it worked fine, I've not messed with the bundled cable since.

Solution for me
Hi,
I had this exact problem, wouldn't sync with any PC/laptop tried all the active sync's and tried all the options in there. Also tried multiple cables and still no joy.
This needs sending to HTC for them to fix. Go here:
http://service.europe.htc.com/Tracking.aspx and book it in for repair.
This is a known fault that happens with these phones and they fix it without charge.
However, don't be like me and try and fix it yourself, otherwise you'll be £70 lighter. I thought one of the mini usb prongs wasn't making contact (as it still charged ok) and after messing about the little plastic in the mini usb port came out. HTC said I damaged it and so had to pay for repair. If I had just left it alone they would have fixed it.
Also when they fix it they should load on for you Rom 1.93 which I'm finding is making the phone so much better. Its worth the money I've had to pay just for that TBO its soooo much slicker now.
The reason why this fault has developed (that some people have said) is that some car chargers are delivering too much power for the port especially when plugged into the car charger and then starting your car. I've seen that the normal charger delivers 5 volts and 1 amp so i've bought a car charger that does the same volts/amps from here:
http://www.dealextreme.com/details.dx/sku.688~r.53733725
I've used it once and it hasn't fried my Diamond yet. (it did however come up asking to activesync or usb drive when it was plugged in unlike the standard charger which doesn't prompt at all)
You also buy the official car charger which is more £££
You'll be without your phone for a week at least and you'll have to install your apps on it again.
Hope that helps

Hi,
I know this is an old thread, but thought i would add what i found as google brings this thread up when you search for this issue. I read through the solutions and through i would remove and reinstall mobile device centre. I found it had gone! Dont know why. I didnt uninstall it and havent ran a system restore etc. Anyway i reinstalled it and problem solved I think Bluetooth might have also been interfering.

help - connecting to PC via usb not working

Hi, ive got little problem, maybe i turned something off, or i dont really know. When i try to connect my phone via usb cable into PC nothing happens, its only charging my phone, its not communicating in any way with PC. i've tried several usb cables but with no success. even the charing cant be turned off, when i press do not charge while connected (or whatever it is) nothing happens, and it keeps charging. ive got dutty's rom (but dunno which one, its the one with HD2 manilla)
thanks a lot for help

Hi.
is the usb connections menu appearing when you connect the device to PC? (on your TD2..where you can choose between Activesync, Hard Disk mode and Internet sharing..). USB connection used to work and stopped after something was installed? Try to reinstall Activesync or Windows Mobile Devices Centre in your PC (depending on you OS) or, as a last resort, hard reset your phone (backup your stuff !). I would also try to connect it to a different pc, just to be sure..Be also sure that the following options in Start/Settings/Connections/Usb to PC are:
Activesync [checked]
Fast data synch (or whatever it is) [checked]
Put a checkmark on the last option if you want this menu to come up every time you plug the USB cable.

ive tried it on several PCs but no success, so its not PC problem, no tab of choosing which type of connection to use appears. Like it's only charging, not communicating with pc i guess that i need to hard reset it >.<

hard reset didnt work, still no connection between pc and phone, i dont know what to do >.< hope that its not hardware problem. any ideas ???

same thing happened to my D2. i had to send it in for a repair

that's what i was afraid about,,, HTC warranty service here in svk/cze is not-so good as i've heard. And another problem is that i have cooked ROM on. With usb not working there is no f-ing way to get stockSPL back . Wonder if they repair it, or if i would have to pay

You can flash stock rom through SD card, about sspl I´m not sure.

so i guess the phones from svk/cze have fulty usb ports because mine was also from there. the thing with me was that i live in USA so i had to wait for them to get the parts and they scratched my phone so i had to send it in. i got it back then the screen was scratched. i had to send it in again and when i got it back the camera didn't work. i argued with them so much that they just gave me a new one.
