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.

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!

i did whenever i custom rom'd it, it still does the same thing. yes it will connect via usb while in bootloader but will not during regular phone operations lol

"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.

PC no longer sees HD2

Weird problem - when I plug my phone into my PC via the USB cable, it charges (i can see the red light and the plug in icon) but the PC via WMDC doesnt see it. Nor can I see it when I view Computer. I have since did a factory HD2 reset and also uninstalled WMDC (twice) and reinstalled. Anyone know what the prob here is or how to fix? Thanks.

Have you flashed any ROMs recently? I had this problem when I flashed a new ROM. My front USB ports were very slow, I don't even think they're 2.0 half the time as Windows tells me to plug stuff in faster ports but, to solve your problem I think you need to change how your phone acts when connected via USB to PC.
Go to Settings, Other and USB to PC and make sure its set to ActiveSync.

That's not a solution it's a workaround and a crap one at that because all it is doing is disabling the usb rndis driver in favour of the much older and slower usb serial driver

I had this problem with my leo all last week. Then i went to my brothers place for thursday through saturday and had the same problem on his pc which runs windows xp pro sp3 (mine is windows 7 pro).
Turns out it was the phone itself. There seemed to be a problem with the tcpip stack, the rndis driver or the tcpip cache. Not sure which but a hard reset solved it and now everything is fine. Although thinking about it i only got the problem after enabling the tcpip cache tweak in bsbtweaks 1.6....... curious!

Don't plug your phone to the front usb, instead plug it to the usb ports on the back of your computer which directly goes to the m/b.
Flashing new ROMS has nothing to do with this phenomenon.
Bad USB cable or bad usb port could sometimes cause this, too.

I have not flashed the ROM at all w this phone. I did do 2 hard Leo resets but still have the problem. Running Win 7 Pro, checked the USB settings on the phone and its all good. USB plugged into the back of the PC and have tried multiple ports. Dang. Any ideas?

I had the same problem, I tried to connect it to several other PCs with no success, at the end hard reset solved it...

if a hard rest doesn;t fix it then task 29 the phone and reinstall the rom

Trust me, the prob is not with your phone, something to do with your PC. Any firewall program running, maybe?

Sorry mate but your wrong. The PC is fine. It is actually the phone that is at fault.
My experiences last week prove this and with no modification to my PC but only a hard rest on the phone everything is now working fine. The same with my brothers machine. No modifications made to it just my phone and that works fine now too.
Both PC's are completely different including the operating system yet both displayed the same problem last week and both now work fine with only the phone being worked on. Combine this with the other comments here that confirm this and you still think the pc is at fault? i'd like to see some proof or some form of methodology.
Although i personally had never seen this problem before over the many winmo devices i've had i'm pretty confident that my IT systems diagnostics training is serving me well here but if you can prove otherwise i'll gladly admit i'm wrong.

sorry for the newbie question but how do you hard reset? i know how to soft reset via "clear storage". i don't have access to the manual right now. out of office.

using clear storage is performinf the software version of a hard reset. it's not a soft reset.
the prefered way of performing a hard reset is to hold down both volume keys (make sure you do it firmly so both make contact) and then quickly tap the power button (do no hold it down at all) then hold the volume buttons until you see a warning. the rest will be obvious (printed on the phone screen)

Sorry mate, *perhaps* your IT systems diagnostics training is serving you most complicated solutions, whereas *maybe* there's more simple solutions : (1)check if there's a firewall program running that block the phone's RNDIS driver to be "seen" by the PC, or (2)a case of bad USB cable, and then (3)your *methodology-proven* trouble-shooting method.
I can say that because it happened to me, where after I take care of the firewall program, the phone gets detected immediately.
Cheers, mate.

First, most modern firewall programs actually have application detection and notifiction systems. Now in cases where the rndis connection has been working and no modifications have been made software wise this is instantly ruled out. In your case i would look at replacing your firewall with something a little better
Next, (and we will use my personal case for this as i'm sure it will be global for this thread) i have one usb cable for my leo - one - and considering, as i said above, after i hard reset and using the very same cable as before i have proven it to work. so moving on.
my method of testing is a pretty standard method. The training is only of any use for tracking the fault diagnosis. Being able to this do allows for an accurate analysis of what is going on at each stage of the connection process.
Seeing as the op has hard reset the device we will see if it is really the PC or not. i'm positive it is the phone that is not working correctly in this case but we will soon see.

Interestingly I have two notebooks, one for work one for home both run WIN7 Pro (Work one is a SOA standard operating architecture). My work notebook did see my HD2 for a while then stopped, my home notebook still syncs without an issue using the same cable. I can only assume by proccess of elimination that it is not the HD2 and that the problem lies with something on my Work notebook.

SOLVED: It was the stupid cable. I did a factory hard reset and plugged in. No dice. Do I grabbed my spare cable and presto. Fired up immediately. Thanks everyone.

usb connection f***ed

Hi guys!
My device doesn't connect to my PC anymore, can only charge. The PC gives me a USB error and that's that. No more flashing! aaaargh....
As it still charges I suspect a software error, indeed hope for it. Any ideas?

I have the same issue m8. Have done for several weeks now. No idea whats wrong. I was hoping to flash magdlr via sdcard and hope that would sort it out, but can't. I am also having other issues now too, e.g: excessive battery drain within winmo. When you turn screen off in winmo, it comes straight back on. Poor reception now (with any radio) was working fine before.
Android is now suffering too, poor battery drain(more than normal) poor signal.

Too bad. None of the other issues with me, though. Tried reflashing from sd, successfully, but no effect on USB, same for bootloader.

you need to give us more info on problem, what error do you get?, does xp try to install usb drivers when you plug in your phone?
Have you tried uninstalling and reinstalling your USB drivers / use another PC, cable etc?

Hi
Tried 2 PCs, a Win7 and Ubuntu. Ubuntu just doesn't see anything at all, W7 says a broken device is connected and refuses to proceed. Will do one more experiment and report back later. Thx for your interest

doesn't sound good to be honest. You could try flashing your ROM using your SD card though in the hope it is a ROM problem.

Sounds like a hardware problem to me. Have you tried a different usb cord? If that isn't the problem I'd make sure there aren't any damages prints in the phone's usb port.
Those are the most likely, it's rare that an internal hardware problem would only break part of the usb port

Hello at last some one I can help.......Maybe
I had the same problem, Mine also kept on trying to put me in car kit mode and turning loude speaker on. I think the problem started when I sat on my phone while it was charging. It some how shorted the USB in side the phone and I had to get it repaired under warranty. But.... if you havent got the same car kit problem try really blowing inside the USB normally one of those air cans ive heard has done the trick.

Hi guys
As stated earlier I reflashed off sd, still charge only. Will try one more thing with the W7 PC. Oh, well, no NAND for me...

If you've updated your antivirus or flashed a new ROM, you may need to uninstall your antivirus, connect via usb, and see if your phone is detected by your PC and WMDC. Then, reinstall your antivirus.

Yes the antivirus thing kind of worked.. and btw go for ur stock rom...

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.

If not, then Im off to a samsung service centre I think.

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.

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.
