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.

Dopod 900 Not Recognised By Pc

Hye, im a new forum user. Ive been using a Dopod 900 for quite sometime now and i love it. However, 2 weeks back, upon connecting it to my pc, an error message showed on my pc screen. It said
"USB DEVICE NOT RECOGNISED
One of the usb device connected to this computer has malfunctioned and windows does not recognize it".
At 1st i thought it was a minor problem so i decided to soft reset it. But after soft resetting it still couldn't connect.
Here's the list of things that i've done.
1. soft reset the device/pc
-connect it via cable to the usb port, still not working
2. uninstall/reinstall activesync 4.5
-not working either
3. hard reset device
-also not working
4. reformat pc (last resort)
-no avail...sigh...
HELP!!! It's driving me crazy!
The usb port seems fine, i can sill charge my device, but i can't connect it to my pc!
PLEASE HELP ME!
Thanks in advance.

the problem is on your PC and not on your Device. I didn't get whether you have formated your PC or you planning to??

I don't think it's my pc.
Went to a pda shop, asked the person in charge to have a look at it and he too was confused. He got the same error as i did on his pc.
He reset my device to bootloader mode and plugged in the usb cable. Something like 'usb cable' showed on my device screen. He said that the port was fine so it had to be some other problem which of course he doesn't even know.
Btw, i DID format my pc before going to the pda shop. Still nothing...Thanx for replying and being so helpfull...Hope u can help some more!

Have you tried a diff USB cable

Yup! Tried a couple of different usb cables...still no luck...
Additional info-
I found out that syncing could also be done via bluetooth from a friend, so i gave it a try but, also no go...my device is not recognised...***sigh***

Yes, still no luck...Ive tried a couple actually...

Was this problem solved?
I have the exact same problem. I got it to sync one time though when I disabled my firewall. But that's it.
I can't sync again.
Please, anybody who had had this problem, please share the solution.
Thanks a lot!

Have check this?
Goto your device -->settings-->connection-->USB to PC and check or uncheck advanced network functionality

That's strange. i don't have the USB to PC option on my Connections menu.
I've been suspecting my USB port to be the problem.
Could anyone please take a very clear picture of the USB port in their Uni so I can compare mine.
Thanks a lot.

Nope...it was never solved. I ended up selling my dopod. I was so frustrated. *sigh*

What ROM ARE YOU USING?

No connection through USB cable

since a few weeks, i've got a very strange problem with my blackstone.
when i connect the usb cable to my phone and the pc, it don't asks me anymore wether i want to connect it as a harddisk drive or do active sync. it's also impossible to do active sync by usb since this moment. i already tried everything in the blackstone USB2PC settings, like disabling fast synchronising, deactive/active the USB2PC pop-up and so on...
what i found out yesterday is the following:
because i did a hard reset, i didn't had any contacts on my phone, so i tried to active sync over bluetooth. that worked perfectly and after the synchronizing was finished, the USB connection worked again, but only for a few minutes. afterwards i had the same problem again. nothing happened when i connected the USB cable. i was able to do the same thing again: synchronize by bluetooth, connect USB cable and it worked again for a few minutes. unfortunately i wasn't able to flash hardspl during this time period. it found the phones bootloader version, but when i wanted to start the flashing process, it said that it can't estalish a connection to the phone (tricolo bottsreen has been started and progressbar was visible, but on 0%)
i also tried it on 3 different pc's with 2 different USB cables...
normaly i would say now, that my blackstone has a defect due to the fact that i did a hard reset and it's still not working, but how is it possible that it works for a few minutes after synchonizing by bluetooth?
does anyone has an idea??? i don't want to give away my lovely blackstone for warranty
btw. is there any possibility to flash a new rom without using the usb cable? even with the soft spl method i've found, you have to use the cable even if the rom itself is flashed from the sd card...

Black Stone usb device picking as "unknown device"
i am also having the same problem please help me

Maybe i'm having a similar issue:
My HD is not recognized anymore via USB Cable. I tried different computers with different Windows Versions. (7, Vista, XP)... No Connection anymore.
Bluetooth Connection works!
I did follow all suggestions... nothing works.
Could it be, that i flashed my HD too much? Is it broken now?

have you all checked your 'USB to PC' settings?

Yes, checked every of the common suggestions given in this situation.
Could it be a hardware fault?
As i told, it doesn't work on any PC! Feels like Touch HD's mini USB port is dead. Strange thing ist, that it says chargin when connection the cable. But no other reaction than charging.

is there still no solution for this problem?
i already found like 20 people now with the same problem, posting in several different threads. seems like this really is a big problem of the blackstone...

I had this problem with Duttys rom afgter plugging my HD into works pc to use internet sharing.I had to do a hard reset to sort it out sorry ts not much help but its the only way i sorted it after buying 3 new leads!

Using the stock ROM 1.14, never ever flashed a ROM. However, for a few days, I have been unable to connect my Blackstone with Windows Mobile Center (OS = Windows Vista SP1), it just fails with an (unspecified) error. I can only connect my device as a disk drive, not via ActiveSync anymore. It used to work before.
I am currently investigating whether or not the recent firewall upgrade (to Norton 360 3.0) on my computer may be the root of the problem. I'll keep you informed...
EDIT: performed an uninstall of the Windows Mobile Device Center, restarted the computer, re-installed the WMDC using the HTC CD provided with my Blackstone -> voilà, it works again
EDIT2: probably my problem was not related with the ones described here above, but who knows, maybe it will help others ...

i also hv the same problem

I already have Blackstone. Maybe You already checked Settings\Connections\USB to PC location. There is "Ask me first about USB connection type...". If my understaning is good then here must be this checkbox set to checked.
Second thing for those users who cannot use syncing only : I had and antivirus program and it has personal firewall. When I turned OFF antivirus protection and the firewall protection then the Windows Modile Device Center start working without any problems with Active sync in my phone.

I checked all, but these are not cases
Interesting, I did a sync last night and today, I can't do it!
But if I use the phone as a modem for Internet, my blackstone connects without problem through cable.
Wich is the mystery?

I solved the problem. It seems that the ROM version was the problem for me:
ROM: BS_Cloudy_1.9
RADIO: 1.14.25.24
Manila: 2.5.20121225.2
I solved using "Clear Storage." After reset, reverting to original settings (original settings actually were, because I put this ROM only for two days), I was able to connect to the PC and was able to flesh another ROM
I hope that this ROM is more stable.

Hi guis, I have de same problem with usb connection, I would to send my blackstone to assistance but i have to instal first the original spl!
Is possible to restore it trough memory card and non trough usb??

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

believe it or not i have done that mannyy times and did alot of device manager things to try and let both computers recognize the hd2 but still nothing haha..
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

@k20a1
Try to hard reset the phone.
It worked for me.
If not again, then use your warranty!

"Disk drive" mode not working with XP laptop
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.
HD"/Leo does not appare in Disk Manager (I know ablut the drive lettering issue)
I'm sure its my XP issue, but I havent found drivers to fix that, and I'm not about to reinstall XP on my lappy in near future.

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.

my HD2 came back from repair
I've got my HD2 back from repair centre... and it works fine... most bizar part is paper say that nothing was done...
