USB connectivity issues

No computer detects my TyTN anymore. Not even to display the "New Hardware Found" message that I usually get when plugging the TyTN into a USB port of a computer that hasn't seen the device before. Nothing. The phone still charges and the it still knows when its plugged by the icon on the lower right corner of the screen.
I've searched the forum for this very issue, and found mostly activesync issues/solutions. I've tried them all with no success. BTW activesync works for me via bluetooth. My last resort was a hard reset. Three times... (read from one of the posts). Now I'm stuck with a TyTN with a Dopod ROM.
Has anyone experienced this problem?
I tell you, having a kick-ass phone but without a way to push the customization files into it is TORTURE.
Please help.

I had a smiliar problem when I Installed XP-MCE.
I solved it by downloading the latest Active Sync and Installing it, From there windows picked it up as a Mobile Device.

Thanks for the reply. I use ActiveSync 4.5 on Win2K, XP and XPMCE. The computers are not able to detect it at all.

Reinstall Activesync
Try reinstalling Activesync (which will uninstall the earlier install of the same or earlier version). This worked for me. I face this problem once too often coz I sync with my desktop and laptop.

try deleting the partnership on the phone and then try plugging it in, make sure all the partnerships on the phone are deleted, i had the same issue with my tytn and that solved it.
Another issue i had was that windows was detecting the device but still would not allow it to connect , so what i did there was just go into computer management (right click on my computer then click manage) and uninstall the device while it was connected then unplug and plug it back in and windows re-detected it. Also make sure you have the atest version of active sync installed.
Hope this helps

Check device manager - does it even refresh when you plug your device in?
If it does not, you may have a big problem...
Have you tried an alternate USB cable? It could be that that is shot.
Have you still got the min-USB headphones? If so, do they still work?
If they do not work either, that would suggest that the device's USB port port is shoddy...

And reality sinks in...

Yeah, I think the USB port on my TyTN is partially dead. This feels like being with Verizon and their locked phones. Sucks wet cow butt.
Oh well, I'll just learn to live with my Dopodish phone until HTC comes out with TyTN III.
Thank you all who replied.

PC wont detect my HD via USB

Hello,
I have got a real annoying problem with my HD. When i hook it up to a PC via the usb cable the phone is not detect, and i have tested it out on 3 different laptops. I tried a soft reset, turning the phone on and off and my last resort was a hard reset but it still dosent work.
When connected to my laptop the phone can charge via usb, and when the screen is turned off and i plug in the USB cable the screen turns on so it does know it connected. Is there anything else i can try to get it working? or would it possible be a hardware fault on the phone?
The rom version installed is 1.56.405.1(43972) wwe, radio version 1.13.25.4, protocol version 52.62.25.34u. I baught the phone from mobiles.co.uk, has anyone had ay experience with sending there phone backs under warranty to get problems fixwd?
thanks
samie

Do you have under 'Connections' settings tab (the three Windows Mobile settings tabs) a USB-PC Icon, if you do go into it and change the USB behaviour to/from advanced connection, if you have it !
That solved it for me, didn't like the advanced settting on mine.

yea, i went to the USB-PC setting and i tried all the different options but no luck. Mine only has the options Active sync(with a tick box under it to make the sync process faster), second is disk drive and the third is internet sharing. It dosent have an option for advance connection.

Are you trying with windows mobile device centre?

Have you also tried another cable, if you have a ps3 its the same connection and some camera connectors are the same too

It depends what OS you have on your PC is it XP or Vista
Sometimes the software isnt up to date so the phone charges but doesnt sync
Try downloading the latest drivers/software for your PC
This is active sync 4.5
By the way what are you trying to get done on active sync? are you trying to sync to outlook?
Or do you just want to look at your phone like a disk drive?

i have windows xp sp3. Active sync version is 4.5 as i did read previosly other version did casue problems with syncing.
I am trying to copy some music over to my memory card and some cabs so i can install some software. Only strange thing i last night the phone connected fine as a disk drive when i copied some music across, and since then i havent installed any new software or done any software changes on my laptop and my phone when i connected it today, firstly i tried to do it as a disk drive but it wasnt detected, so then tried active syn with the tick box selected but it didnt work so diabled it but it still wasnt working.

From what I have read the sync may have been messed up from the music or other files transferred sometimes it due to calender Im not sure what the prob is.
Have you tried deleting the connection in activesync? then reconnect
also your SD card may be causing it Try accessing your card on your PC, take the card out of your phone and use the adapter for the card
Have you also checked the options in Activsync on the phone are they all ok?

hi all, I also have the same problem with my HTC HD...
ROM version: 1.18.707.3 (23358) WWE
ROM Date: 12/10/08
Radio version: 1.09.25.14
Protocol version: 52.49a.25.26U
My problem is the same as what SST had described. All my PCs and laptops in my home and office are unable to detect my HD phone when I connect the USB cable on it. The HD screen only showed a battery charging icon while my PC/Laptop doesn't show any device connected. I am using Ms Win XP Pro SP3 on my laptop and Ms Vista Ultimate on my desktop. Active Sync 4.5 and Ms Mobile Center has been installed respectively on each computer. I have change to different type of mini USB cable as well.
Before this, everything was fine. This only happenend 2 days ago. I have tried to soft reset for few times and hard reset for twice. It can't solve my problem. I even tried to delete all the Windows-PC that is available on the HD, but still the same problem.
When I take out the mini SD card and try to read it using the SD adapter on my computer, it cannot detect anything on the media. This is very weird, but when I insert back into my HD, it works properly in the File Explorer and I can access all the files inside. I repeat a few times and the same thing happened.
Without ActiveSync, I can't even upgrade my ROM if there is a new update available.
I really have no idea what happened on my HD. Appreciate much if anyone can enlighten me on these 2 issues.
Thank you in advance!

Can you access USB when in Bootloader?
you probably know this but if you dont.........turn off phone, hold volume down button then turn phone on it should show tri colour screen
with serial written on bottom, plug your usb cable in hopefully it will say USB
atleast then you can flash
Try also deselecting faster connection on comm settings and you can also look here

hi ozmoran, the white portion screen only shown "serial" even I have already plugged in the USB cable... any idea?
thank you in advance.

this may sound a bit basic but are you using the usb cable that came in the box ?
I've found certain cables won't connect my phone to PC/laptop, they'll charge fine but no connection.
For some reason the phone seems picky about which cable it uses.

When in bootloader, disconnect usb and then re-connect it to phone. If bottom of bootloader doesn't change from 'Serial' to 'USB', you may find that your usb drivers need updating. Here is a guide to update drivers.
Also, before updating drivers, ensure that all correct settings in activesync have been selected i.e. 'allow usb connections' in connection settings.

Hi, Spartan. Thanks for your help.
I tried to update the USB device but the device manager doesn't show any USB-WinCE drivers at all. I guess my HTC HD USB port is faulty. Anyway how, my set is only few months old, I think I will sent it back to the dealer for a warranty claim.
Will update you guys again! Thanks!

quick update....in the end i gave up and took it to carphoneware house to get the problem sorted. They sent it off to their repair centres, who would have just flashed and updated the firmware. That didnt work so they sent it off to HTC who replaced the main board. so it looks like the mini usb connection was the source of the problem.

Thanks for the update bro
Its good to get feedback so everyone has more answers in future

The problem solved : i had same problem, after read and searched I switch and use USB to miniUSB's cable of my camera which have a round filter it pop right up (Active Sync and Windows XP).

lol @ Tihuyh!
Im having a similar issue. USB connections were intermittent, i updated the windows drivers and everything was great. Now for some reason is stopped working, havnt been able to connect by USB at all. The device doesn't show up in device manager and the bootloader screen doesnt change to USB. it will charge tho and i can access the SD card from my card reader and it works fine in the device. Its quite frustrating tho, looks like my phones going back to orange

Just goes to show that similar problems don't necessarily have the same solution.
Thanks everyone for there input. Hopefully this will help others with 'similar' issues

USB connection issue

Hi everyone,
Since I'm new with this phone (just bought it few days ago) I really need your assistance.
My problem is probably with the usb drivers (Mass storage device). I'm running on Vista Ultimate SP2. When I connect the phone, and go to the notifications, there are two (as supposed to be). HTC Sync and the one with the USB connection. Well the one with the USB connection appears and disappears all the time.
As a result I can't sync since there is a problem with the USB driver. When I disable the Mass storage device (this is the one responsible for that), I can sync. The problem is I can't use my phone as a storage card in order to copy files. In advance I'm saying that I tried to mount the sd card...nothing.
I've tried the phone on other pcs, XP and vista... it workds everywhere fine. The notification with the USB connection is not disappearing.
Tried everything, rolling back the driver, updating etc. nothing!!
PLEASE HELP ME!!
Thanks in advance

Also remember than not all USB cables are the same.
I'm not using the original one as I lost it with the original box.
But while the Nokia DKE-2 works great for all functions, my camera and my USB HD mini-USB cable only support few features.
All of them can charge the Hero, though.

The one I'm using is the original one! Moreover, the phone connects properly with other pcs!

So the problem is Vista.
I personally used XP with only some minor problems due to the cable.
http://forum.xda-developers.com/showthread.php?t=557310

It should not be Vista... I've tried it on another pc with Vista.... no problem!!

Oops, ignore this.

Have you tried different USB port on the sick Vista PC?
Have you installed Andrid specific USB drivers? If so, uninstall and reinstall.
When you plug the cable do you get on the phone the notification for USB connection?

Adding a question to the topic:
I own a Galaxy right now and consider switching to the Hero, one thing that does not work with the Galaxy is the USB connection to my car for audio playback. The USB interface of my car can't handle multiple drives as offered by the Galaxy; e.g. with a HTC snap everything is fine.
So the question is: Does the Hero offer one drive only when connected in the USB mode?
Thanks for your help!

Cant connect hd2 to computer!!

this is my problem,
when i connect my hd2 it charges but the computer doesn't recognize it. on the phone settings it is set to active sync. i also have 2 computers; xp and vista, both do the same thing.
i could careless about active sync, i just want to plug my phone into my pc and transfer files in and out. ive also tried the disk drive option but still no go?
if i enter bootloader and plug it in it recognizes the usb setting but when the phone is normal, it doesn't??
it did this with the stock rom and its also doing this with nrg titanium rom.
any help would be appreciated

Same thing here.
It charges through USB but it doesnt connect.
If i choose the storage option it works fine.
I want to sync my outlook and i cant...
What the heck...?

i know this may seem a bit "it helpdesk-ish" but try re-booting your PC

Come on... give something drastic!
Already done that, rebooted the pc and the hd2...
still nothing

ive had previous hd2's and they've all connected fine untill this one, maybe its this specific one thats giving me trouble. but regardless, it charges via usb then it should be able to recognize it

Check the active sync settings to ensure that usb connections are enabled. You can tell be looking at the system tray icon - there's a read circle with a white X in it if USB is disabled.
Saying that though, if it doesn't even recognise it when the device is in USB mode, I'd try a different cable. It's perfectly reasonable that the cable could power the device but not fully facilitate a USB connection.

That is very weird. Sorry mate - never heard of it doing that for anyone before.

Make sure you have the mobility center/active sync program installed on your computer. Without it it won't work.
On Vista or Seven, with the HD2 plugged in, you can find the program/drivers by launching and refreshing manually Windows Update. On XP you have to do that manually.
Good luck.

This happens to me often. In my case I have found it to be a weird driver issue. Go to device manager and look for the yellow triangle. Right click and update driver software. This worked for me I hope it helps.

bit late but just flashed maxsence and i love the look, but have allready had to restart by phone 10 times in 10 minutes. I'll wait for the next release. back to GTX for now.
Good work NRG. keep it up.

this is one of the many WM6.5 errors!
need Android soon!

Ok here we go.
The phone did not connect through activesync to my pc. When i selected to connect as mass storage it connected.
I checked for driver issues in device manager but nothing came up.
I checked the hd2's activesync. Bingo! the activesync was crashing when i was running it. I had to hard reset the phone.
Now it works fine.
My guess is that maybe a program that i installed recently was buggy and created this particular problem. Unfortunately i have about 50+ programs installed (including themes etc) and i m not sure which one it was.
I was installing all the programs again today one by one and after the install process was completed i connected the hd2 to usb to find which app was the problematic one.
After installing almost(some were found useless) all of the apps (here is the crazy part) the hd2 still was connecting through activesync....
HTC will drive me nuts...
Anyway the phone now connects correctly.
I cant understand which was the problem....

as odd as it may sound i think i figured it out.
i think its the usb cable that im using, i have to wiggle it around for it to connect to active sync but once it connects its not a stable connection as it cuts in and out.
but charging capabilities work though!
pos wire, i ordered a new wire and if that one fails also, i will have to get my hd2 replaced for faulty usb port
thanks for all the replies much appreciated

HD2 is working fine with my desktop, but wit laptop I can only use ActiveSync to browse files.
When I connect the USB cable I get:
"Found new hardware wizard"
but it tells me that it Cannot Install This Harware - Disk Drive
"An error occurred during the installation of the devie The system cannot find the file specified"
And I only have "Finish" to click - if I click it the wizard lunces again immediately and goes on and on with no end.

I share the same here and I was despaired of trying to solve it with any logical, as well with illogical, measures. Such as: rebooting, changing usb cables, reinstalling activesync 4.5, etc.....etc...blla..blla...blla...
However, I solved the "Transfer files issue" by taking out the sd card from the HD2 and connect it with an external cards reader to my pc.
The card reader connected and works with the same usb cable that does not work with the HD2.
That way I load it with all files and in the same occasion I reload into my computer the daily spb backup files.
However, I have the feeling that the reason for that problem is a missing file/driver named: "Setup1.SPL" in the pc windows operating system.
In order to solve that it seems that only reinstalling windows on my pc will be the solution which defiantly do not like.

HD2 won't do active sync

2 days ago I lost my active sync it just doesn't work, I connect my device to my pc and i doesn't even light the screen though it does charge :S... I've tried everything possible: Hard reset, Task29, flashed a few rooms (throught bootscreen and SD card) tried in a different PC but nothing seem to work. My X1 does do active sync in the same PC. I don't know what else to do... has anyone got a clue of what to do?... Thanks.

Maybe stupid but, have you tried other USB ports?

Try removing and reinstalling activesync and make sure you do a reboot inbetween. I had this problem once and a hard reset fixed it but that was only because the problem i had was phone side (server side) and not with the pc (client side)

As I said I tried in another PC and it didn't work either, but my Xperia X1 does work so the usb port is all right... Forgot to mention that on NRGZ roms sense looks quite messy now even on the roms I know are workin properly, and everytime I reebot the mob the navipanel pops out, now I change to another ROM and the sense seems ok but the home button pops out the navipanel. Its so strange :S:S!

In that case i can't help with the activesync issue but the navipanel issue is solved by disabling the auto detection. It is possible that the two are linked but i had the navipanel problem with the most recent energy rom and implemented the fix and all is well

Thanks for trying to help, this page is very helpful when device is recognized by PC, but has ActiveSync profile mismatch. The first thing that I did is I've disabled fast sync on HD2, then I've deleted all profiles and their traces on PC and HD2 as well. Usually it helps when you plug in the phone, computer acknowledges it, but pop in warning sign that USB device is not recognized or recognizes it but fails to initiate ActiveSync. In my case there was no reaction (on multiple computers) - like nothing is plugged in... Will see what repairer says... I'll post an update as soon as I'll hear from them.

Yeah I have the same problem any PC just doesn't recognize the usb connection.

The link above covers what I'd try next in a round and about way.
Can you connect to your PC by cable in disk drive mode (>>Settings>>Other>>USB to PC)? Can you connect ActiveSync via BlueTooth? Can you synchronize with gMail using the Exchange settings for the service? The above tests should give a better idea as to where the problem is; whether with ActiveSync or the USB connection.
There's a great site covering ActiveSync problems. It's out of date but still relevant. Search for ActiveSync Troubleshooter by Chris de Herra.

I had problems with active sync a while ago.
The HD2 would charge but was not recognised by active sync.
If you put the phone into bootloader it says 'serial' at the bottom of the screen
When you connect it to your pc via usb, this should change to 'usb'
Mine didn't.....and a bit of reading around showed that this means the usb socket is faulty.
I sent mine back to HTC and they replaced the motherboard and I've had no problem since.

People, come a little help, no way can I synchronize the phone with Windows, I have Windows 7, and installed Windows Mobile Device Center, but they can not sync to make, that would later be some ROM and Radio ROM I put, these are unic few days. I went to microsoft and my phone and there I upload everything and write synchronization is successful, but when Connecting your phone and choose sync anything, open the Mobile Device Center and not conected! Does anyone know the easiest way to sync? I would be eternally grateful to him!
I have another problem, the computer I see the SD card, a phone? I do not know what the problem was that I somehow know to help me, not I need to do factory reset because I have 450 phone numbers, and I can not seem to sync them! Means when I go to Start / Settings / sd card & phone storage, no write down my sd card? And all the programs that are on the card normally do not work! I ask for help!
Thanks in advance!

Got the same problem with Windows 7. Should have stayed with good old XP. Is there no way to get this so called driver?

Have you tried a different USB / microUSB cable?
I had one with a single broken wire that wouldn't charge but would pass data. Maybe you have a broken data wire.
