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.

Problems connecting

I have a tmobile MDA Vartio2 and I have numerous problems with it and need to upgrade soon but this one I cant sort.
I can't connect via usb to sync with my laptop. If I set up a new connection it will sync but as soon as I reattach to sync it wont recognise the device so I can't keep everything up to date. it isn't the cables - power is fine and they work for other things.
I am runing it as I bought it 17 months ago - no upgrades or cooked roms or changes of any kind.
Can anyone help.
I want to upgrade to something else but I always sell my old ones so I want to sort the issue first obviously even if I sell it.

Try turning off the 'advanced network functionality':
Start -> Settings -> Connections tab -> USB to PC
That's what I had to do to get that hack called activestin...^WActiveSync to work reliably via USB.
Really, I've not noticed any difference between having it on and off as far as functionality goes, so really, I have no idea what the RNDIS mode stuff is even good for.

I have just tried your suggestion but now it isn't recognising the device at all. It is seeing it as far as power goes - its charging over USB but activesync isn't seeing it.

Check activesync itself:
File -> Connection Settings
Make sure "Allow USB connections" is checked.
If that still doesn't work, I'd try the uninstall, reboot, reinstall activesync dance and see if that helps any, provided that you are using activesync under XP.
I'd also be suspecting the sync cable. Recharging a device and getting a data connection are two different things. I have a blue angel that wouls charge via the USB sync cable, but would not sync, XP kept complaining about an unknown device. Turned out it was a broken wire in the cable.

Done all of these already I'm afraid - I have 4 or 5 cables and none of them work for this - and I know they are all absolutely fine.

OK, let's take stock of things. I'm assuming that you are using XP.
Hermes with the advanced network functionality turned off doesn't show up at all when you plug it into USB. So, we have a lower level driver issue going on.
Provided that you have not turned off all sounds in your current sound scheme, does the computer make any noises when you plug the phone in? If the data side of the connector on the phone is in order, the computer will make some kind of beep noise when you plug in a USB device.
Also, have you looked at device manager when the phone is plugged in? With advanced network functions turned on, a network adapter should appear. With out the network bits, it should show up as an HTC USB Sync device.
To eliminate something on the phone software-side (I know, you said that you have not touched anything, but try it anyway, this is windows, the environment that gave rise to the term bit-rot), put the phone into boot loader and plug it in to see if the computer sees it. It should appear as a HTC USB Sync.
If it still doesn't show up, I'd be popping over to another computer and checking to see if the phone will be recognized by that system.

For the past few weeks when I plug in I get references to acquiring network addresses (like a wifi network) but then it does nothing. Now I get nothing at all when I connect apart form power.
I have already tried re-installing active sync (just done it again in case I did something wring too)
I refuse to beleive its my cables at this point because I have 3 in front of me that all worked perfectly before everthing suddenly went wrong. Unless someone had cut all of them at the same time - this couldn't have happenned.
I am going to try and plug into the pc and see what happens (as apposed to the laptop which should have the connection.

I think this is good news (on the part of my laptop) because its the same story on the pc.

Double edged sword there...
So we have potentially eliminated the computers (good), this leaves the phone itself (non-good).
Hard reset?
Otherwise, I'd start to suspect the USB connection on the phone itself.

I would say that my chances of rescuing this phone rather than getting a new one are getting slimmer
I think it is probably the port itself and I can't do anything about that one
Anyone want to buy one with non usb syncing functionality ?

[Solved] HD2 Connection problem with Win7 & WMDC

Massive problem, HD2 gurus please help me here:
HTC HD2 & WMDC & Win7 x64 = Not working.
I've downloaded WMDC x64 bit from Microsoft's official site, installed the app, plugged my phone in the USB port..... and nothing happens. Win7 x64 does not pick up the phone via any of my USB port (I've tried like 4 different USB ports already).
Here is the weird part, Windows doesn't even pick up the HD2 as an USB device. I doubled checked via Task manager, and nothing has been detected. I have scanned for new hardware via the device manager countless of times.
Nothing shows up, not in device manager, nor control panel. Having WMDC installed doesn't help either, the app simply doesn't recognise HD2 via USB cable. Even with WMDC uninstalled, Windows just can't detect my HD2, but when I plug my Nokia N97 in the same USB port, Win7 picks it up as a mass storage device straight away.
Basically the phone will only charge the battery from the USB port, and nothing else. Win7 x64 doesn't even flinch when I plug the phone in, nothing pops up, WMDC says no device is found. I've tried just about everything, googled a bit and it seems like I'm not the only one that's suffering from this problem.
Here is a list of all the possible solutions that I've tried :
Ran WMDC as system administrator

Had the same issue last night when I first tried to sync my HD2. Same issues, ended up being I needed to update the Bios on my motherboard. Ironically it worked after I plugged it in and failed the driver install. Then went to Device Manager and ran update driver for the picked up devices. Works like a champ now. Hope this helps in some way.

Somehow I doubt that I will need to update my motherboard's BIOS, as my PC picks up the Nokia N97 perfectly fine. Having said that, I'm busy dling my mobo's latest BIOS right now.
Will let you know how it works out.
Edit : Nope, just as I thought. Didn't rectify the problem, thanks for your advise though.

Okay, the BIOS update scared me for a second there. I didn't revert back to the default setting after the BIOS update, which made all the USB ports malfunction on my PC. I couldn't use the keyboard nor the mouse, but I solved that problem by clearing the CMOS with a jumper.
Anyway, that's not the problem... The PC still wouldn't reconise the HD2. What I have noticed is as soon as I plug my HD2 in the USB port, HD2 automatically runs the activesync.exe
Having said that, the PC still can't identify the HD2 as an USB device. Absolutely zero response from Windows 7 x64. I've been trying to rectify this problem for over 6 hours already. I have googled dozens of pages, tried just about every single solution (bar the formatting option, which I will leave it as the absolutel final resort).
Please, can someone help me.

Gentlemen, have any of you tried a usb hub?

For the heck of it, have you tried it on a different PC? Have you tried a different cable? I am not sure what cable the N97 uses. I apologize I'm not trying to be an ass or anything, just wanted to find out if it's the handset's micro USB connection problem.

Yes, I have tried it on two different laptops, both have Win7 x86 installed.
I didn't install WMDC, instead I just plugged the HD2 in the USB port, hoping that Windows will automatically download WMDC and install everything on it's own. But alas, no luck with that either. Laptop could not detect the phone via USB cable, nor Bluetooth.
EDIT : OMG, I think I found the solution. Thanks, N1M1TZ. You actually did help me by suggesting the switch of USB cables. Since the Nokia N97 works flawlessly on my PC via USB, and the fact that both the HD2 and N97 uses the microUSB format, I was able to get the HD2 hooked up to the laptop. So it seems like T-Mobile's HD2 USB cable is the culprit. Well, it's in the bin now, I'm gonna use N97's USB cable for both of my phones in the future.

I'm glad you got it working. I had the same issue with my usb cable. Went out and purchased a replacement cable and found this ReTrak USB to micro USB cable. I have used their cables for most of my stuff from patch cord to adapters instead of my cables getting tangled or tied up together.

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

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.

USB Problems Since Upgrade to 2.2.1

Since upgrading the Galaxy S to 2.2.1 which I absolutely love - must faster than anything previous, sleek, really well done, I've just noticed for the first time that my USB doesn't seem to work.
The computer sometimes sees it but just says the device is malfunctioning, the phone sometimes sees the PC and gives a menu for "ask on connection", but Windows just does not know what this device is at all.
Suspect I may have to reinstall the drivers fully in Windows, remove it completely and try again, if it actually showed up as an unknown device in Device Manager.
I do need to try another PC and cable just in case, but this is what Im having at the moment in Windows:
USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.

I've done a quick search on this. Hopefully this is as simple as doing a factory reset and format the internal sd.
If not, then Im off to a samsung service centre I think.
Any further thoughts?

Factory reset the phone, but the USB port still is not working. Charges fine, but don't connect over USB to the PC.

Can it be in debugging mode. Try to switch between mass storage and kies.
Probably you have checked that already..

Now i am looking to install untouched rom in order to give it to service but when i am trying to flash from recovery i get an error . Any suggestions?

This may sound dumb, but it could be the USB port acting up (loose connection). Try wriggling the cable around or use a different port.

Right, I've tried all available USB ports, two different computers, two different OS's. The phone just does not register a USB data connection. It only recognises AC charging according to the logs.
I think I have a broken USB port on the phone as if I jam the connector in at an angle on the phone, it sometimes registers the data connection but its far too unreliable.
Development mode don't work, Kies, Mass Storage etc... anything. Nothing works.
Factory reset doesn't make it work.
I can't even flash a new ROM as the phone is not detected in download mode.
I've got the phone booked in at a Samsung Service Centre now. I've seen a few webpages referencing corrosion. I tell you what though, this phone has been protected way way more than my old N97. I've had so many phones and not one has suffered from "corrosion". So let them just try and say it's my fault. Im ready for em.

Try cleaning your phone usb port. A guy named omersak had the same problem, and he had solved it. Search for the thread started by him, and how he has solved it.
I hope you can solve it without going to the service centre. And good luck.

Definitely trying that first - thank you to all the people that have been doing the investigation.
It sounds to me like Samsung have got a bad batch of USB connectors that should be replaced under a factory recall.
I don't use mine in a shower, or sauna, or anything like that, I don't even use it in the rain.
The closest it gets to any humidity is being in my shirt pocket from time to time.
Im going to get some meths or something like that and some thin paper and see what I can do with that. Im just off to Homebase!

there are similar problems on the galaxy 3 series where usb suddenly stops working. the following solutions seem to work there:
1. dial *#7284# to open "PhoneUtil"
2. in USB section, switch to modem, and then switch back to PDA
if that doesn't work: reboot into recovery and select "wipe cache partition"
*hth*

I've tried both of those before I start splashing the methylated spirit around. Still no joy.
Wipe Cache don't work, as well as wipe data/format sd/restore factory defaults etc.
I think I've got a 100% hardware fault.

@OP,
I am terribly sorry about your case. Looks like you need to make that trip to the service centre.
At least you have tried out every possible means known.

Any suggestion?

I'm not an Expert but 2 hints from me:
1. If you have'nt tried yet: Install usb-drivers on pc new and then connect your phone and wait until drivers are installed to your phone.
One times this way worked on my i9000.
2. Look for a zipped rom on xda which you can directly download and install from sd-card.
