[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.

I have returned the phone to the store. I will have to wait two weeks if they fix the problem. But thanks away

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?

I've been working with another member on this issue. Go here and read through my suggestions and see if one helps. The first thing I would try, is to uninstall sync manager and all drivers for the phone from your pc. Then, connect the phone and see if it reinstalls sync and the drivers. I hope this helps.

I think is problem is large. After update htc one sucks. no doubt it added some great features. Or it may be hardware prob as always with HTC specially with HTC one X

usb problem
mine has also stopped working. does charge but not connecting to computer . running xp so drivers ok . definitely phone problem as friends htc one connects fine..

Disable usb debugging, it will connect

usb problem
thanks , but tried everything. wont connect in fastboot, recovery or anything. cannot relock bootloader or return to stock so just returning it for warranty as it is with fingers crossed. unless someone can tell me if possible without connecting to pc.

are you using a usb 3.0 port

usb problem
usb 2.0 . i have two friends with htc one's and they both connect just fine.

Same issue here! Last night pulled my phone out and it said "incompatible charger, please use original charger". I wasn't even charging the phone, and now it wont charge or connect to PC unless the phone is off. Tried turning off debug/developer/power save/fastboot/ etc with no luck so far.

[Q] HTC One No USB Mode

Something happened to my HTC One. It no longer shows up on the PC when hooked up via USB.
I have tried resetting the phone, factory wipe, installing different ROMs, and switching on and off the developer mode. No luck.
The phone still charges from the wall charger... but will not show up as a drive at all.
Is it a hardware problem which requires service or is it a software problem which can be restored?

In the notifications window on the phone, does it say USB or MTP connected? It might be a driver problem on your PC

Nope. No notification on the phone. There used to be one showing when USSB is connected.
I've tried on a number of PCs with no luck. I installed the HTC Sync application as well.
When I plug it into the machine with the HTC Sync software, the HTC Sync software launches but says no phone is connected.
The phone used to show up as a device in Explorer... Not sure how to get it to do that again.

Are you using the USB cable that came with the phone?

mine did that, had to get it repaired, luckily Vodafone AU do service swaps so only had to walk to a store and say its broken.

Yes. I have tried with the official cable along with others.
I mean, it is a USB cable though. There is nothing special about it... just like there is nothing special about a Monster Cable HDMI either. Just a cable.

Check you have the htc drivers installed correctly.

There are some USB cables that are charging only.... Anyways, I think it may be a hardware issue

I had to have new mainboard on mine .

[Q] Trouble connecting to PC

EDIT: Solved Turns out it was the USB port not my phone. my HTC One XL had the same issue till I changed ports.
So I am trying to connect my Z3C to my PC to enable helium so I can get my backed up app data. My first problem is that my computer doesn't recognize that the device is plugged in. I don't even get the sound from a device being plugged in. The phone charges over usb but i can't access it in anyway. I downloaded sony PC companion app but still nothing. any help is greatly appreciated.
Has anyone had similar issues?

[Q] HTC One m7 Charging but not recognized by computer

HTC One m7 4.4.3
Hello,
HTC one m7 when connected to computer, nothing happens. it only starts charging. computer doesn't detect phone. I have read every single thread regarding this issue and tried all suggestions including:
- different original usb cables were used
- HTC drivers installed . multiple versions
- HTC Sync Manager installed from HTC website . multiple versions
- different cables were used, different ports, different computers
- factory reset has been made, and wipe cache as well
- started in safe mode
- checked usb debugging and unchecked it
I tried another HTC one (NOT updated to 4.4.3) and it worked fine.
I sent emails to HTC Support and they didn't reply. I used the online chat in the HTC website and the person was talking doesn't even know what USB debugging is .
My question is: Could it be a hardware problem although the usb port is working for charging? if not, what else should I do?
Thanks

Yes it could be (and probably is) hardware related even if its charging correctly. Usb port have 5 contacts: +5 Vcc, Data+, Data-, ID/sense and Ground
If Data+ or Data- contacts are defective, the computer won't be able to "speak" with the device. Power will however be connected to charge it via pin 1 and 5 (+5 Vcc and Ground).
Pin #4 (ID/Sense) is a floating contact, only used to determine what is connected to the device (Charging dock, OTG, car dock) and if the phone must act like an Host or like a Slave device.
You should try to clean your usb port using isopropyl alcohol or some electro-contact cleaner.

I am having the same issue, but I think it has to do with installing a rom, and not first updating the firmware. I restored to original 4.4.2 through twrp but it did not fix the firmware issue. I am wondering how can i update the device firmware without usb?
