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?

[Q] USB Connection?

I am on CDE-AOSPb3.1 on JI6 Froyo.
I am having a USB device not recognised error on my Win7HP x64 machine, and it is not allowing me to connect my SD cards to the computer. This has actually culminated in a BSOD on my computer, presumably because something is wrong with my phone and the USB connection was messed with. The BSOD, however, was isolated, and has not happened again; a full reboot of the phone has not helped this issue.
Any ideas? Or is this a Development question? I have run this ROM since its inception, and have never had a problem until now. It does still charge on USB, however.

You could always try going back to your previous ROM that was able to be recognized by your desktop. If it does recognize it, it might be a ROM problem.

A Nandroid restore didn't work, because the actual root of the problem was a bad micro-USB cable. Borrowed a colleague's and it's all good now. Time to buy another...

[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?

Thanks for the suggestion major. I tried those drivers with no luck - the message still pops up frequently in both charge and mass storage modes.

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] Can not connect to my PC

It has just stop working when a plug in my usb to my pc i do not get "Turn on USB storage" on my phone. No usb icon also. The computer does not recognize the phone.
I have try different cables, computers and OS. Also did a factory resat and putt on debuging mode on and off. Also multiple restarts with no luck. I use stock rom.
Are my phone broken?

It's probably the usb ports though you have tried with other computers ;/
or the micro-usb port of your device

I had the same problem and I believe it is a phone issue. I tried reinstalling drivers, different USB ports on different machines, factory resets, different cables etc. At times when plugged in the phone would suddenly wake up and acknowledge the USB connection while at others it just started charging when plugged in to USB.
What confirms that this is a phone problem rather than a PC problem is that when I connect it to my office workstation that runs on Sun Solaris, it behaves pretty much the same, acknowledging the connection randomly. My HTC Magic on the other hand always connected to both home PCs and office workstation without any issues every time.
Finally I have returned my handset and asked for a replacement.

Good luck. It's a pity though as otherwise my handset worked perfectly with no reboots lags etc. I hope the replacement comes in soon and is bug free too.

I have the same issue with my macbook. Since yesterday my o2x isn't recognized by my mac.
I know it is not the usb cable, or the (micro)usb port, because when i plug the phone in at night my alarm clock on the o2x fires up (as it should).
So a connection is made, it just doesn't show "turn on usb storage" on my o2x. And i cannot understand why.
I am on the 0606 baseband, with the new FR19 ROM from Paul O'brien's Modaco (which is excellent btw).
If anyone has a solution, please let me kno

I have the same problem with my phone under modaco fr19, baseband + ril 606.
My pc is under windows vista and the drivers are installed correctly.
Awala

Update:
I received a replacement handset which was V10D 20110405 out of the box. No issues with USB connection.
Just out of interest, did any of you leave the phone connected to USB for a long time before it started failing? I used to leave it charging via USB all day at work so just wondering if there is a connection...

Update:
I earlier stated that my O2X wouldn't connect to my macbook. Yesterday I connected the O2X while on the Windows Vista partition of my mac, and it connected without any problem. After that, rebooted to Mac OSX partition, and no problem there. So I am a bit puzzeled about why, but it seems to work again.
In reaction to mparack's question, i sometimes let it load overnight via usb cable. But not a lot. I do not think that was the cause. I thought it was caused by flashing the 0606 baseband, but now I do not think that was the culprit.

Got back my phone from Telia on Wednesday. Everything worked fine. And I upgraded the phone using the LG update (Basbandversion: 1035.21_20110622) LGE version LGP990-V10c). After that the same problem! It feels like it's a bug in the software. Then they have changed the mainborad and it sounds unlikely that the new one is defective to.Goning back to Telia on Monday if they know about a bug or if you can get a new phone.
Those of you who have had the same problem what version do you have? Can I downgrade phone in anyway?

[Q] Windows 7 64-bit not seeing phone

Hey all,
Recently I have gotten need to RUU my phone. It has a custom hboot 1.56, S-OFF, and is running CM11. My problem is that my computer will not recognize my phone whatsoever. In fact, it doesn't even show up in Device Manager OR the "Safely Remove Hardware" icon in the task bar. USB Debugging is enabled on my phone, and I am using the adb binary from the RUU package.
What's strange is that Windows doesn't even bring up a message to try and install drivers or anything... it acts as if nothing was ever plugged in. On my phone, nothing happens except it begins charging. Not even a USB storage popup or anything.
I'm not really in a location right now where I can test out another computer to try that, nor do I have a spare cable handy at the moment. Has anyone ever had the problem I've having, and if so, what was causing the problem/fixed the problem? I'm thinking it's the cable, but I'm not really sure since it CAN charge the phone.
Thoughts?

It's probably the cable. I had to install CM on a Tab 2 for my friend and his cable didn't work, only charged, so I had to get another cable, which worked fine.
