USB device is not recognized error.

Hi all,
I'm experiencing the above problem. It started last week when I tried to reflash the firmware to a third party firmware. The unit could power up as normal, wifi, bluetooth all working fine but not the USB. I've tried installing a utility which switches the mode from RNDIS to USB but it still failed .. hard resetting the device does not help either. Is there a way that I could revive the USB connection? I couldn't sync my contact etc at the moment with my PC.
BTW, currently I'm on Onyx Jr. 4.1.2. I could not update to any firmware due to this and I don't have microSD to SD converter which I could use to copy the firmware to the microSD.
TA.

Disconnect sync cable. Reconnect to different usb port on computer. Right click ActiveSync in taskbar. Click connections. Make sure "Allow USB connections" is checked. If above fails, uninstall usb adapter in device manager, reboot computer. It'll reinstall with stock drivers after reboot.

It may happen due to faulty USB cable. Try and use another cable and on some other computer and check

I've tried all that I could think off including removing activesync and reinstalling it back. I've few miniUSB lying around and I've tested many of them but my notebook just did not want to recognized the htc touch. I've tried using those cables with my wife's tytnII and they worked .. could it be the hardware problem inside htc touch itself?

Tried with a new USB cable found in my newly bought GPS and if I reseat the cable properly, my notebook could recognised the htc touch. So I guess a new cable does help.. thanks all for the help.

HTC HD2 Won't charge or be recognized via USB

Hello,
** I posted this in the Windows forum but I have since flashed to Android and the problem continues so i'm posting on here for hope that someone will help **
I recently successfully installed Windows Phone 7 rom onto my HTC HD2. The phone was working fine and would charge the battery when connected to a dedicated charger on the wall plug as well when it was plugged into another computer. I recently attempted to plug the phone into the computer via USB only to find it wouldn't recognize it ,no prompts on the computer or the orange light on the phone. I turned off the phone, removed the battery for several minutes, I started the phone up again and it would boot into Windows Phone 7 normally without any errors but still it would not be recognized by the computer or allow itself to be charged by an external battery power. I had read somewhere that if I where to select Mass Storage option off the bootloader that it would charge the battery and create a partition on the computer. Huzzah! the computer recognized the partition, but the battery still wasn't charging. Here are the direct steps that I took since I got the phone:
Phone: HTC HD2 T Mobile
1. Unlock the phone (successfully)
2. installed HSLP3
3. Flashed Radio leo 2.15.50.14
4. Installed/Flashed MAGLDR113
5. Using USB Flasher installed the LEO70_ROM
6. Flashed Android 2.2
That's all no settings afterwards were messed with, and Windows phone 7 came up normally and worked perfectly.
Side notes:
-I have tried multiple micro USB cords and different Socket Wall Chargers.
-I have tried multiple computers that never had the phone installed on it before and it won't recognize it.
- USB Flasher on MAGLDR does work, the phone recognizes that it is connected to the PC and the PC installs the drives when applicable.
- Boot loader (multi color screen) also isn't recognized on the computer when connected in that mode.
- I have used USDEVIEW to uninstall all USB connections installed previously on the computer and still it does not pick up the phone.
Any assistance is greatly appreciated.
Thanks,
Mr_Pickles

I have a question, when you connectcyour HD2 to your computer via USB while in bootloader you do not get USB in the white bar of bootloader or HTC USB sync in the safe to remove device?
Have you checked your battery pins on your HD2 to makecsure none of them are out of alignment or bent in any kind of way?
Also your HD2 should show up as MAGLDR in the safe to remove thing when you havecit connected to your computer and select option #4 USB Mass Sty or option #5 USB Flasher.

Hi T-Macgnolia,
Thank you for getting back to me so quickly, please see below for answers to your questions.
Q: When you connectcyour HD2 to your computer via USB while in bootloader you do not get USB in the white bar of bootloader or HTC USB sync in the safe to remove device?
A: No it doesn't, the White bar stays at "Serial" and HTC USB Sync does not appear on the "Safe to remove Device" section on the computer.
Q: Have you checked your battery pins on your HD2 to makecsure none of them are out of alignment or bent in any kind of way?
A: All battery pins are straight, there are none that are bent or out of alignment.
Q: Also your HD2 should show up as MAGLDR in the safe to remove thing when you havecit connected to your computer and select option #4 USB Mass Sty or option #5 USB Flasher.
A: Yes, it does show up in my computer in the "Safe to remove" section when plugged in during option 4 USB Mass Storage and option 5 USB Flasher. The phone also recognizes that it has been connected to the computer while in the USB Flasher mode, so I'm still able to flash other ROMS.
I hope this helps you diagnose the problem. Thanks again for your help.

Ok from what you told me you still have working data connection via your micro USB portcon your HD2. The no USB in the white barcode bootloader could probably be fixed by downloading and installing the most recent version of ActiveSync or WMDC from Microsoft, depending on which Windows your computer uses. Those programs contain USB drivers for Windows Mobile devices. But that is just for data transfer not for power transfer.
It kinda sounds like you maybe, and I stress maybe have some problems with the power pins on your HD2. If you have access to a multimeter you could pull your battery outand plug your charger into your HD2 and test from the positive pin to the negative pin (look at the battery to tell which is which) to see if you are getting voltage to the battery.
My best suggestion to you is to flash a Windows Mobile ROM to your HD2 and see if it is charging then. If it does charge you know your micro USB port is working, if it does not charge you have a faulty USB.port. Download and install the above mentioned ActiveSync or WMDC to regain your HTC USN sync while in bootloader.

Hi Mr_Pickles did you ever find a solution to your problem, im having the same issue with my HD2

Yes, I had exactly the same issue. Think it is Window7 related. Found myself a PC with XP, installed active sync 4.5 and solved it

Problem with usb connection

Hi guys ,my problem is that when I connect my phone via USB cable at first there is no problem, data transfer , windows mobile device center, everything is OK. But when I want to flash the phone pressing vol-down + switch on/off keys the phone is not connected to the PC. And I can't flash it. Also the phone wouldn't like charge trough the charger ,only with the data cable. Is it possible to have any liaison between the problem with charging with charger and no-connection when try to flash.
Also my phone was to the service for touch-screen change ,is it possible the technician make any mistake ? Cause I think that if he make a mistake with the connector nothing gonna work ,but it works at different situations.
Regards!

check to be sure USB SYNC driver installed correctly and also try a different usb cable.

I'll try but there is no logic ,the cable works when charge the phone, works when is connected to device manager but doesn't works when flashing ?

exactly. the device requires different drivers.
1. there is internet sharing and disk mode (which works with all computers, because those drivers are in the operating system)
2. then there is one driver for syncing
3. and another one for flashing
it is not the same kind of data transfer, which is why you need a different driver. but the thread "[tut] updating htc sync drivers" should cover all your windows vista/7 driver needs and a tutorial on how to install them, which in case of a x64 system can be fairly complicated.
if you already have hspl installed (which you can determine by entering bootloader mode and looking whether it says 1.56Olinex), you can also flash using the sd car method. put a rom of your choice on the sd card, name in BLACIMG.nbh and enter bootloader mode, you will be presented with options to flash the rom.

Ok, but in instructions at the thread you give me is written that I have to start making the steps after I see "USB" on the flashing screen. But I don't see it, it's only "Serial". And now what ? I know that if on the screen i written "USB" the phone and the computer are connected and there is no problem to flash ,but now what ?

well, before you start, put your device into bootloader mode. it will show "serial", then connect it to the pc. test your connection using mtty 1.42 (you'll find several download options here in the forum).
the connection settings for mtty are USB 115200-8-1-No-NONE-None
if it works, connect and press enter, the command shell should show USB> then.
if usb is not present in the connection settings, your connection is not established yet. proceed with the tutorial then. during the entire procedure, the device should remain connected to the pc in bootloader mode, so you install the driver for the right device state.

Hello,
I've problem something like this. Few months ago when i was conecting my phone to computer was everything OK, activesync, disk drive, but now nothing, just charging the phone. I've tryed everything in USB to pc zone, but nothing. When i'm going to bootloader it's writen serial. What can be here?

since you already tried all the different connection methods and even bootloader mode does not connect, there are hardly any options left, where the trouble could be:
- the usb port on the blackstone
- the usb port on the pc
- the cable
you can try another port on the pc (or even better, another pc altogether) and/or another cable, like from a digital camera, an external hdd... (many devices have mini usb cables, you should be able to use either one of those)

[Q] HELP with recovery, no usb access to nexus 7, not detecting with official cable.

Ok so long story short, i have a nexus 7 2012 which a rooted and installed cyanogen mod.
I was using it as a car install and works perfect, i'm using an otg cable to mount usb sticks, triggering soft shutdown and powering the nexus etc. So usb seems to be working fine.
Basically i removed the tablet it to modify the bootloader to turn on automatically with ac power applied, if the battery runs out i have to manually power on with button, but now i'm running into a problem.
Ever since taking the tablet out and trying to connect over usb, none of my computers detect the tablet.
I've tried different operating systems, drivers, cables etc etc.
Also changed from mtp to ptp in storage and also turned on usb debugging mode. If i connect an otg cable the nexus see's the otg and i can mount usb's etc.
So i thought i might try recover the nexus back to factory, maybe there was an issue with the rom corrupted etc, I've downloaded the original 4.2.2 firmware which is currently installed.
Booted into recovery and tried re-installing the 4.2.2 zip, it keeps aborting. A guy in work tried to use sideloader and connect via adb. no luck.
I'm not very familiar with the android platform so i've no other ideas what to do and other idea's how to recover now.
The guy i work with mentioned using a usb jig, would that be the way to go or can anyone else suggest some else that might help.
Thanks

Before you updated when was the last time you connected your N7 to your computer?
When you connect your N7 to your computer does it act like it is charging? Have you tried more than one computer? I had a similar problem with mine last year & sent it in 3 times. Asus replaced both the USB port board & the main board on different occassions. I suspect your mainboard might be faulty.

Does adb see the device

I last connected the nexus to the laptop a few monts back to load some music onto it, didn't have a problem. It's only been connected to a computer maybe 3 times. once to root/rom it then another few times to load music etc.
I can't see why the usb board maybe faulty as i can read data from a usb key when the otg cable is connected.
It's a strange one. You could be right, i might try pick up a broken nexus and swap some parts. Usb board etc.

Yes adb is shown in device manager, but it's not recognizing the nexus, comes up with an error 10 , cannot start. etc etc

I am having this same problem on my (unrooted) HTC One after attempting to "convert" it from an AT&T to a Google Play Edition device with the procedure described here.
As part of the procedure, I attempted to flash the stock Google Play Edition ROM using fastboot commands, but I got an error message. The instructions say to just try the flash again, but the phone no longer connects properly via USB (error 10) while in bootloader mode. While in bootloader mode, the phone indicates there is some sort of problem (a line showing the OS version is highlighted in red), and attempting to enter recovery mode does nothing but display a phone with a big red X in it. The phone seems to operate fine and responds to ADB commands when the phone is fully booted, albeit with the old OS (not Google Play Edition) still in place.
Any Android device could theoretically get in this state. We're sort of "paralyzed", because everything we want to do to regain control of the bootloader and fix the situation seems to require issuing fastboot commands from a computer connected to the phone while it's in bootloader mode. Yet entering recovery mode or getting a computer to connect to it via USB no longer seems possible.
I wonder if there's another way to issue fastboot commands without relying on the USB connection to a computer?

usb only charges, no data transfer

my nexus 6 will only charge no data transfer and pc wont recognize it. When i connect it to the pc it goes staright to charge mode and the usb trident symbol doesnt ever appear. In developer options usb configure is stuck in "charge mode" only. Ive tried different roms from pie to mm . i reinstalled bootloader and radio, tried twrp back ups and still the same. Had new charging port put in phone thinking that was the problem but didnt help. Ive searched google but couldnt find anything. Any Ideas, really appreciate it thx

When I installed stock rom which was android 7.1 it changed phone back to encrypted. Now i have to format internal drive in order to install a pie rom. Does anyone think that formatting internal drive might fix problem with not being able to do anything but charge phone from usb port, because if that doesnt fix it there would be no way for me to put any rom on my internal drive to install it.. Does anyone have any suggestions

Just to double check that adb devices shows your serial #. If not, it may be a driver issue.

Computer doesn’t see it, when I enter adb devices it doesn’t show up. Nothing shows up in device manager either: Also when I enter fast boot on the phone “power lower volume button” it says “connect usb data cable” I’ve trued numerous cables that work fine on my other phone. So it’s not the cable. After I plug them into phone it still says connect usb data cable.

I also have a thumb drive with a micro usb connecter that used to work on the phone. Now the phone doesn’t see it when you plug it in to the phone. But it works on my other phone so it’s not the thumb drive

It sounds like a driver problem. Is it a windows PC? Have you tried installing the Google USB driver? I've had similar issues, and reinstalling the driver(s) has worked for me.

It’s windows 10 and I reinstalled driver, other thing is in my car when I plug it in to the usb slot for android auto, it doesn’t show up in my car either and it used too.

It’s like the phone is stuck in charge only mode and I can’t get it out of that

When you connect your other phone to your PC, does its serial # show up in adb devices? If so, I'm out of suggestions.
1 more thing.. Have you enabled USB debugging in Developer Options?

Other phones shows up and in devolpers options in “usb configuration” you can set it to mtp but when you hit enter it goes back to charge only. I was on” aiop 14.0 rom” when it happened but it was working fine on that rom , then one day android auto kept saying connect usb, so when I got home I tried to plug it into pc and nothing. So I replaced charging port thinking that was problem but it didn’t help. Flashed other roms and even went back to stock, reflashed bootloader nothing helped. I was hoping someone here had seen this before cause I googled it and nothing like this could I find

Forget USB configuration for a minute. In developer options, under debugging, USB debugging needs to be enabled.

usb debugging is enable also. even tried turning it off and back on again, didnt help.
you know when you connect phone to pc and you normally see the usb trident symbol on your phone, well when i connect it to the pc i dont see that symbol it just goes straight to charging but even charging i should still see the usb symbol and i dont,
