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?

No USB connection?

For the last year I've had my Diamond, I've never had a problem (for the most part) connecting my diamond to my laptop via a USB cable.
But last night when I plugged in my USB cable into my Diamond, it said that it didn't recognize my USB device.
I blew it off thinking I just needed to reboot my computer. Turns out tonight after investigating, this is a common problem with Vista and USB's.
Anyone have a cure? I've read till my eyes bleed, I've done reboots, edited the registry, installed, reinstalled programs and drivers till I'm blue in the face.
Today I got my HD in and it won't connect either. Obviously I have a problem with my laptop but I need help.
Anyone?
Thanks,
Mark

did you try another USB-Cable? Maybe its broken or something

One of the reasons I don't use Vista
Put XP on it, but that would be an extreme solution maybe? Is there someone who has similar problems with Vista?

Thanks all but it looks like my USB connection is just dead at that connection.
I say that because it doesn't work when I switch cables nor devices, I get the same result.
Yet, when I use the USB connections on the other side of the computer, they work. Apparently that one USB connection died.
Thanks,
Mark

[Q] Captivate USB charges but no data connection - flashing stock w/o ODIN

Just a quick question- I have a Captivate that will charge when plugged in via USB but there is no data connection. The phone doesnt recognize that its plugged in to a computer, and therefore despite being able to boot into download and recovery mode, I cannot use ODIN to do anything. Clockwork wont work either due being on 2.2.
Ive read some other threads where most concluded it is more or less a hardware failure. Im coming to that conclusion myself, but wanted to check with you guys first. The audio jack did the same thing for a couple days-- it wouldn't work when plugged in. It did come back on its own, though Im not sure why.
Im running Cognition 2.2beta3, and cannot flash back to a stock rom nor to any other rom due to the lack of being able to use ODIN.
Is there any other way to flash back without ODIN? Also, if this is indeed a hardware failure- how can I go about getting it fixed? I traded for it on craigslist for an iPhone 4 so I didnt get it direct from AT&T. It did work for the first couple months.
Thanks in advance for your help!

Do you have USB debugging enabled (Settings-Applications-Development)?
If so, you won't get the connection choice screen when you plug in your USB. You can either disconnect USB debugging to get the choice screen, or leave USB debugging enabled and click on the "Select to copy files" choice in notifications.

I have tried with USB debugging on and off, and in various USB modes. None work, as the Captivate doesnt even acknowledge theres a data connection that has been made.
It worked in the past in all modes... debugging with the option to mount the drive, mass storage, Kies, and the media mode. No dice at the moment. Tried a hard reset today... nothing.
Looks like it could be a hardware issue-- just weird as the audio jack had the same issue and seemed to (randomly) resolve itself. Thanks for the suggestion! Any other ideas?

I had the exact same issue as you few days ago. One forum member recommended to me to uninstall the Samsung USB driver and reinstalling it again. It worked as soon as I did this. You should give it a try.

I had a similar issue when performing a master clear and flashing JI6. I am on windows 7, and I noticed that a different driver is needed to use Odin in download mode. I had been sideloading apps as well as transferring files with the stock driver from samsung, but my computer still wouldnt recognize the phone when in download mode. The solution was quite simple, when entering download mode my computer gave me the "driver not found" messege. I just let Windows Update find the right one for me (not sure if its generic or not) and everything worked fine after that. Hope this was relevant to your issue.

And I guess you can't do the phone off, open Odin, plug in USB with vol up/down pressed, right?

Not sure if this will help, but I bought a second USB cable to carry in my laptop case. If I use it I can charge the phone but cannot connect it to a PC. If I use the one that came with the phone it works fine.
I have actually tried some other cables and they have issues too. They all have a larger cable housing towards the end that plugs into the phone, where the one that comes with the phone is slimmer.
A friend at work as a Fascinate and he has the same issue, we suspect that the increased size is keeping the usb from connecting all the way in the phone.

Ive tried different computers and different cables, as well as different drivers. Ive used 64bit systems and 32bit systems... XP and Vista.
The phone itself goes into download mode, though I have to go through the terminal and use 'reboot download'. I cant use command line on the computer as it doesnt find the device... the phone never is identified to it. It just charges.
Is there any way to perform the commands that ODIN does without actually using ODIN? If nothing else, Id like to flash back to JF6 and be able to use the OTA updates. At this point, Im stuck till clockwordmod works with 2.2.

I experienced the same thing. My Captivate would charge, but it couldn't connect to any of three computers (WinXP w/drivers, Mac OS X, and Linux) with either of two micro usb cables I had. I would always get a USB error in some form.
I was on cog 2.1, and was able to roll back to the JH7 OTA update without ODIN. Afterward I brought it to an ATT Tech Center and convinced them it was a hardware failure.
I got a warranty replacement, and it didn't work either.
It turned out to be bad micro usb cables. One was the original Samsung cable, but it was loose, there was plenty of play and wiggle in the sockets of both phones.
The best micro usb cable I've found is from a Kindle. It has a a larger plastic base than the stock from Samsung, but critically it has a longer connector. There's a solid click when connected and absolutely no play or wiggle possible. It works every time.
I don't know if you can restore from 2.2 to JH7 without ODIN. Now that we have 2e Recovery on Froyo (in Cog 2.2 BETA6), could you use Clockwork Mod (Rom Manager) to flash designgear's JH7 OTA ROM?
Try some alternate micro USB cables, you might be surprised!

Im having the same issue, was there any resolution to this from the OP??
I suspect hardware also, and Ive got another Micro USB on order from Amazon and will prob buy one from a store tomorrow also.
the stock cable is horrible, I bought a nice charger the other day and it has a nice click and stay, and since I plugged it in to the new charger it no longer shows up on any computer with the stock cable. Im wondering if the new charger with a tad larger connector spread the connectors just a tad too far for the stock cord.
I tried everything as well, I hard rebooted, put into recovery mode and even deleted all my user data to try and see if there was some software that was blinding the computer to the connection... no luck
Ill let you know what I find.

Same issue here. Has anyone had any luck with a new usb cable? Luckily, I can transfer files from my computer via bluetooth for now, but it takes forever!

[Q] Windows "USB Device Not Recognized" error

Does anyone else have this problem? When I connect my phone to either my laptop (winXP) or my desktop (win7x64) I periodically - constantly, really - get this message:
"One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message."
When I click the message, it identifies my phone as a Generic USB Hub (4 ports) with the first child being a USB Mass Storage Device, the second being the problematic "Unknown Device" and the last two are "Unused Port"s.
This happens whether the phone is in charge-only or mass storage mode. I tried installing the autoplay drivers and that didn't help, so I uninstalled them. No hubs are involved - I've always plugged straight into the tower or laptop. I've also tried two different quality (first party Motorola) cables.
Mass storage mode works fine despite the error - I can access the Internal storage as well as the SD card. Is this a problem with my phone, or am I missing some software on the Windows side?

Odd... I had issues with the original drivers, but once installed, I never had another prompt again.
edit: I had it one more time, but it found them and installed them

that's very interesting. i also use 2 machines--one with xp and one with win7. my usb connection worked flawlessly on both. fyi...my connection default is mass storage, and i've actually never tried the other options. i wonder why the difference? did you make any changes? are you rooted? i am not.

Hi gr33nT,
Thanks for responding. I'm 100% stock at the moment, not rooted or anything (though it will be soon ) Sometimes I use charge only if I have it connected to my laptop at work but I still want to listen to music from the SD card. I may see if I can get Verizon to swap out the phone, the message pops up all the time and it's getting annoying...

A quick follow-up on this one: I tried the stock LG cable on my win7 machine (I had been using moto cables). I installed BOTH the bootstrap drivers as well as the LG drivers from the web - still happening. I rooted with these drivers via S1C so I know the drivers are good. If nobody else has run into this, something is probably wonky with my phone, so I'm probably going to exchange it.

For mine, every time I connect, it asks me if I want to install bootstrap. Even though, they have already been installed cuz I am rooted.

I've had the same issue both as stock, and rooted and in every configuration with the phone and PC you can think of. I've downloaded the drivers and installed them from both the phone and web site all to no avail. This is really getting annoying.
I hope someone has a fix for this.

Hmm...that is troubling. I'm still having the issue running the stock rom and rooted, now. When I get time I'm going to drop by the Verizon store and hopefully they'll replace the phone - I suggest you try the same, as I doubt it's the computers we're using. My win7 box and winXP work laptop could hardly be more different!

I doubt a replacement will fix anything, I experience the same thing as majorpay. Drivers worked for a while and then it started asking for it again. This also causes issues when using usb tether as its connecting and disconnecting. The issue is not present when used as a mass storage device.

Hi bwhxeon,
The issue (USB device not recognized - it sounds like you're referring to the autoplay driver installation) happens for me in mass storage mode also. I believe it has to be the phone as I've never had this problem on any of my PCs with my OG Droid or any other USB device. With this phone, I have the problem on all of my PCs.

I had the same problem. The error popups seemed random at first. I noticed if I enabled/disabled the WIFI on the device while it was connected, I could make the error popup.
I ended up getting a new replacement device when I also noticed the 4G Hotspot wasn't working either even after a factory restore. There was definitely a hardware issue with the phone.

USB Unknown Device
same issue here.. when using ADB though I have to set to Internet Connection then it goes away for a while until I want mass storage or just charge from USB again, then re-appears.

LG is not like most other phones as in usb debugging only works in internet connection mode where others go into it as soon as you plug it in.

Just kind of scanned this thread but have you tried a different USB cable? I was having a problem with mine only wanting to charge with the stock so I grabbed another cable and it has worked right ever since

Same issue, two different pcs, with two different cables. Bootstrap does not load anymore so I am using the drivers from the links, both sets of Lg verizon drivers

[Q] Connecting to computer problems

Hi all!
I have a Nexus One running CM7.2.0 with Clockworkmod Recovery. My computer is running Windows 7.
I want to connect my phone to the computer in order to return it to it's factory state with an official shipping rom and stock recovery image.
However, I've run into a problem which I've been having for quite a while now; when I plug the phone into the computer via USB cable, it charges, but nothing happens on the computer, and nothing happens on the phone.
I've tried different USB cables, and different computers.
If I push the part that goes into the phone port to the right, the computer will make a noise as if to say that something is connected, but then it will be unable to install the correct drivers, and will say "USB Device not recognized" It comes up as an "Unspecified" device in Devices and Printers, and in "Unknown Device Properties" it tells me that "Windows has stopped this device because it has reported problems. (Code 43)".
I have a feeling that the problem is the port on the phone, but I wanted to ask on here first to see what other people thought. Why is it that the phone charges correctly, but won't be recognized on the computer?
I might just add that this problem first started when I installed a device manager program that allowed me to see my texts and things when the phone was plugged into the computer. It was a while ago, and I think I remember (not entirely sure though!) not safely ejecting the phone before unplugging it, and then 2 minutes later when I went to plug it back in, this occurred. Whether this is related to the problem or not I do not know.
Also, I'll add that this problem has been occurring for quite a few months now, but it is only recently that I have noticed that when plugged into a wall charger, the phone charges much slower than it used to, and the charging light will go on and off every so often. This suggests port wear, but this started happening quite a while after the connection problems happened.
Anyway, thanks to all those who respond! I am keen to work out what is wrong.
Thanks,
Simon

Also I'll add that the SD card works perfectly fine in an SD card reader USB thing!

I'm not sure you properly read what I said..
My phone doesn't work on any computer I try it on. All other USB devices work fine on the computer I am currently using. This means that it is not simply a matter of following the steps you linked, because the problem is not related to a windows error.
BTW, learn how to read properly.

Youshuold change usb cable or or rest the phone.but first of all buckup your data after that phone will stat newely so bug will be gone
