PC can't recognize Desire

Searched other similar topics but not exactly what i was looking for, so here it goes.
My Desire won't connect to my PC. It asks for connection type (charge only etc.) but when i choose Sync or Disk Drive, my PC can't recognize them. I'm using Wind XP 32-bit and latest HTC Sync. I have already tried all USB ports, un/installing HTC Sync and different versions of it. Tried closing antivirus during install and during connecting. When i connect to PC, under device manager it shows Android Phone->Android Composite ADB Interface
I know that phone and cable is fine, because they work on my laptop with win 7 64-bit.
I'm going crazy, HTC help is also useless, in third letter they finaly understood my problem and all they suggested to do was close antivirus and try all USB ports. Please help me.

up........

It's clearly a driver problem.
Enter device manager, in "view" choose "show hidden devices". Then uninstall every driver for the desire (in "disk drives", "storage volume", and in "universal serial bus controllers" - that should be all the places they are; tip if you are not sure about some open properties and check what is says in "location" - should give you a hint).
Uninstall HTC sync again.
Restart win, plug the phone and let windows do the driver installing.

New hardware wizard can't find drivers.

Choose to search online then.
Set the desire in disk mode and connect it again to the PC.
If it again doesn't work, you have not fixed your drivers.

I had problem with windows recognizing my htc Desire when I was connecting to my front usb ports on Desktop computer.
Problem was solved when I connected to back usb port, directly to motherboard.
I see you said you tried all ports but had to share my experience just in case you didn't try the back ports.

How i choose to search online? can't find that option
And if i connect my desire to pc, under device manager i can see other devices->Android Phone (after unsucsesful driver install) and if i select to uninstall that, is that enough to delete all drivers? can't find them any other place.

Select "install software automatically" and then "yes, this time only"
This should not have been needed, though. As XP should recognize your device as a usb mass storage device.
And as for the second - have you deleted them while the desire is NOT connected as described in my first reply?
If you could not manage to fix it again, maybe you should reinstall XP, at least then the drivers will be okay...

install software automatically doesn't give me that option...
But i have noticed this wierd behavior before. Like some time agi when i bought a steering wheel, it was impossible to get it working (similar problem, can't find drivers) luckily i was just about to do format c and reinstall xp and after that, no problem, installed first time... Same thing even with memory sticks, USB TV sticks and so on. How come my pc just sort of "loses" or messes up the drivers?! But i'm not going to do a reinstall, just too much stuff i need in my pc.

Is there anything else you can recommend tring?

[Q] Can't update Drivers

Hey guys,
I've been wary to flash the ROM of my Nexus 7, as it actually boots into the normal OS and does everything fine.
The basic problem is that I can't transfer anything to and from the device over USB. USB debugging is on and I have tried PTP and MTP.
One of the solutions I have been looking at is bad drivers on Windows' part, and that is where I am currently blocked. If USB debugging is off, Windows refuses to acknowledge my tablet's existence. If debugging is on, some drivers from Microsoft automatically install and the tablet is labeled as "unknown device".
My USB controller is up to date with the correct drivers provided by ASUS for my motherboard (ASUS Z87-A). I recently re-installed Windows 7 to put it on a larger SSD, and with this same motherboard, it now does not detect correctly.
If I try to uninstall the "unkown device" it simply disappears until I unplug and replug in the tablet. If I try to manually direct it to the correct drivers, it tells me that the USB drivers are incompatible with my device. The USB drivers are the ones downloaded directly from Google.
I can still access the fastloader.
If you need more information, just let me know.

When you first got the device, did you go straight into fastboot without booting it and plugging it in while in Android? Does that question even make sense?

Use this as a possible quick-fix (not all mode combinations will work right): http://download.clockworkmod.com/test/UniversalAdbDriverSetup6.msi, then reboot.
Use this as a more complete fix (recommended in your case): http://forum.xda-developers.com/showthread.php?p=50253887#post50253887

That would have been roughly a year ago. I believe I did boot straight into the OS.

To the first quick-fix, the ADB drivers are installed, but they are not the drivers that are utilized when the Nexus 7 is plugged in. Like I said, it instantly installs some generic Microsoft drivers, and refuses to recognize the ABD drivers are compatible for the device.
As such I can't even begin with option 2.

With the device plugged in, go into device manager and find the device, uninstall that device, and make sure you check the box to uninstall the drivers from the system, then leaving the N7 plugged in to the PC, reboot the N7, as it comes up it should redetect, it's important to leave the device plugged in while it is rebooting.

There is no check box to uninstall the drivers: imgur.com/PhL4UNt
Where "unknown device" is my N7. Still, I tried rebooting it while leaving it plugged in, and it would not recognize correctly.

You may want to make sure you are not using a hub or USB 3.0 port for this btw.
Put the device into in MTP mode with debugging on, unplug the device, then download these, unzip them somewhere, right click on the unknown device associated with your Nexux 7, click Update driver software, click "Browse my computer", navigate to where you saved the unzipped contents, and select usb_driver folder, let it do its thing, reboot your PC. Plug the device back in, preferably into a different USB port then what you have been using, it should then show up as a Google ADB driver (or similar), you can test it with the command: adb devices see if that works, if not, leave the device plugged in, and reboot the device.
Let me know if that works or not, and I will continue in a new post.

Ok, plugged directly into a USB 2.0 port at the back of my motherboard. Recognized as Unknown Device when plugged in, disappears completely when unplugged.
So, here's exactly what I did: Plugged in device -> clicked on "Update Driver software" -> unplugged device -> Browse my computer for driver software -> directed to correct location -> replies: "The best driver software for your device is already installed", and it is not using the ADB drivers.
Going into "Driver Details" tells me that there are no drivers that have been installed.

Don't unplug the device, do like this, put it in MTP/debug on, leave it plugged in, "Update Driver software" -> Browse my computer for driver software -> direct to correct location.
I know my method works, I've done it to that laptop, my htpc, and my gaming rig flawlessly.
You may have to use a tool to remove all instances of those drivers and reboot, Wugs toolkit has the app, let me see if I can find the direct download for the app or you can just download and install Wugs Toolkit.
Here is the app, but I'd still recommend you install Wugs NRT, as the kit has a walk-through telling you which device IDs to look for to remove. Here is the actual tool wugs uses: http://www.nirsoft.net/utils/usb_devices_view.html, but again, unless you know which ones to remove, you're better off using Wugs tool kit device drivers walkthrough built into NRT.

Well, NRT is precisely where I started this whole thing.
Here is a picture detailing where the Nexus 7 is connected, and for reference, ALL the USB ports on my case, be it at the front or from the motherboard, are controlled by a hub: imgur.com/pP5ZbMv
Every other device's location is described as "Location 0" except for the Nexus 7 when it's connected.
Unfortunately at this point I'm probably just going to use Dropbox to transfer files when I need to.

I guess something is trashed in your system, maybe using a previous motherboard driver would work, dunno, sorry it didn't work out.

[Q] My 8.4 wifi can't connect to windows 7 pc

I have recently root my samsung tab pro 8.4 wifi version. Everything seems to work well, except USB connection to my windows7 desktop. I installed the latest version of Samsung usb driver (download from Samsung's web site for my device). Whenever I connect it, media device mode, the "installing device driver software" icon spins for couple of minutes, then I got the error of "Device driver software was not successfully installed" . In the detail dialog window, it says "MTP USB Device" failed with a red cross. what did I do wrong? thanks.

I have tried several different USB 2 ports on my computers. Also I have Developer mode turned on, with or w/o USB debugging checked. Nothing seems to work. Also the camera mode doesn't work either.

Did you install kies 3 from samsung?, this should install all the drivers you need.
http://www.samsung.com/us/kies/

I tried with this version of kies from samsung's website, not working. Got the same failed to install device driver message.
In windows device mananger, it shows a MTP USB device with yellow "!" mark on it. If I try to update driver from here with the driver installed on my computer, it says I have the latest driver installed already.

Try going to Device Manager in Windows, find the device, pick the option to select from the drivers on the computer, then pick the "USB MTP drivers" (generic, not Samsung) and see if that helps.

thanks for your help. I tried your suggestion, and
I went to the Device Manager, and select the "MTP USB Device" with yellow "!" mark, choose this menu,
Update driver software->Browse my computer for driver software->let me pick from a list of device drivers on my computer
I see two drivers, however either works for my 8.4 pad. It says "This device cannot start (code 10)"
Also when I open the properties for this device in device manager, it shows its driver running is from Microsoft, driver version 6.1.7600.16385. Should be a driver from Samsung?

Are you running stock TouchWiz ROM? Just to be sure.
Otherwise you could remove all your USB drivers related to Android and start from scratch with just the Sammy driver. I had to do that for my previous OnePlus One, it just wouldn't connect. It chose a wrong driver each time I hooked it up so I had to just remove those from the driver store and then make it choose another one. That was for ADB thought, but I guess it couldn't hurt to try anyways.
The reason I'm mentioning if you're on stock ROM is because this morning, on CM nightly 01-24 I had some troubles with my tablet being read by Windows, it was fixed in 26 so.. Just wanted to mention it.

Yes, I am on the stock TouchWiz ROM, but I rooted it following steps from one thread in this forum. Before rooting, I was able to connect. I do have a LG G3 phone connecting to the same computer successfully. Will this cause any problem? Will going to CM ROM solve my problem?
Also, can you tell me steps to remove all my USB drivers related to Android in Windows 7?

It may work to install CM11 or CM12, BUT try this toolfirst (uploaded to my personal box account) Find all your mobile device drivers in this list and mark them and go to "File" and click "Uninstall marked drivers", restart your PC and plug in your tablet. Then try plugging in LG after so it gets drivers later. I'm not sure if it will work. But it should apply new drivers. If it doesn't work, uninstall the drivers one more time and download the Samsung drivers from 3rd party and install them and apply then manually to your tablet through Device Manager in Windows.

Its always a possibility. I'd try to uninstall the LG drivers. You can always re-install later (if needed).
In a perfect world, the Sammy drivers would be what you want. But this is of course not a perfect world. I've had better luck using the "generic" Microsoft MTP USB drivers over the HTC drivers on my HTC devices.

Glad you sorted it out, to some degree or other.
USB connectivity on Android devices is very tricky, at least on Windows (can't speak on other OSes). My HTC phone connects fine to my work laptop with the HTC drivers. On my home computer (also Win7) it frequently drops adb connection and I have to manually select the "generic" Microsoft drivers to make it work (and the HTC drivers never seemed to work completely right either). My Sammy Pro 8.4 seems to connect just fine to my home PC, however. So it seems its just a crap shoot what kind of connectivity you will get, really.

Having Problem Connect Nexus 5X to PC using a USB cable

When I connect Nexus 5X to a Windows 10 PC, I can't see it in File Explorer.
Many people said that one should change the option from charging only to MTP in the USB connection notification, appeared when plugged in. But I don't even have that notification, and cannot find the option anywhere else.
In Devices and Printers, there's a Nexus 5X under Unspecified; and in Device Manager, I can see a "ACER ADB Interface" there which I assume is for Nexus 5X. I tried to download Nexus driver from Google buy it seems is the same with the ACER ADB thing and is not helping.
Any tips or solutions? Thanks in advance!
PS. First xda thread started by me, yay!
UPDATE: After awhile, maybe it's because I slid the screen while connected, the notification did pop up. But EVEN after I chose MTP, there's still nothing in my File Explorer...

Hiya,
I had the same thing happen on my 5X. I was only able to get to the "Use USB for Charge / MTP" dialog by enabling Developer Mode.
To do that: Go to Settings / About Phone, and scroll all the way to the bottom.
Tap "Build number" seven times. On the sixth tap, you should see a message that says "one more tap will unlock Developer mode" or something to that effect.
Back-arrow to the Settings main menu.
Click on Developer options
Look for Networking / Select USB Configuration.
Choose the mode you want.
The notification should appear when you plug in the USB cable to your computer.

Thanks for this info! I'll keep that in mind, but now I still have problem after chose the transfer mode. Maybe it's because I slid the screen while connected, the notification do pop up. But EVEN after I chose MTP, there's still nothing in my File Explorer...

could be a driver issue?
download and install latest usb drivers.
Go to My Computer> Properties>Device Manager> Find the android device>Right Click update driver software>Browse My Computer>set to folder where you have usb driver saved and go from there?
You can also try to let me pick (instead of browse local folders) and pick the google ADB interface from there.
I have also had success in the past using other software (PdaNet) to manage the whole installataion of drivers; but this adds software to both phone and computer ... may or may not be useful.
After re-reading your first post its definately driver related. It shouldnt say Acer just ADB Interface or google adb interface.

Check Device Manager, is it listed as ACER Device? It probably is. It happened to me. Select the device, mouse right, update driver, choose "let me pick a driver" or something simmilar. Then you should get a list of compatible drivers and 2 entries, the current ACER driver and some generic USB driver. Choose the generic USB driver. That did the trick for me.
This i got from reddit . I had the same problem today this link helped me .. hope it helps you too

@arpan_pratik, Thank you! You are the best! This is exactly what my problem is and I solved it using your suggestion!
Although I didn't yet find any useful information from reddit regarding my issue, you must used some magic keywords
@The_Automator, thank you, too! It indeed is a driver issue. I tried many times to update the driver or uninstall the ACER ADB driver, but none of them worked. Didn't realize that it is Windows chose the wrong default driver. Don't know why, maybe it's because I installed adb before?
So, for the record, here are some key points to solve the problem:
The wrong driver for my Nexus 5X showed in Device Manager is ACER Device\ACER ADB Interface
No use to install Nexus driver from Google, even use "Browse my computer for driver software" and search the extracted Google driver folder. Windows will say the driver is up to date.
So I have to do this: In Device Manager -> RMB on ACER Device\ACER ADB Driver -> Properties -> Update Driver -> Browse my computer for driver software -> Let me pick from a list of device drivers on my computer -> check "Show compatible hardware" -> choose "MTP USB Driver" (this is a Microsoft driver under "standard MTP Device" category) -> Problem solved!
Then I can find my Nexus 5X in Device Manager here: Portable Devices\Nexus 5X
After the right driver installed, if I try again to update the driver using ""Search automatically for updated driver software", Windows 10 will actually install the wrong driver (ACER ADB) back!
Thank you all in this thread to help me exclude other possibilities, lock down the culprit and finally solve the issue!

Just got a Nexus 5X, and I'm having the same problem under Windows 10. I don't see an Acer device in Device Manager though, I see a "Nexus 5X" under "Other devices" with a yellow triangle exclamation mark.
When I tried following the steps, I don't have "Show compatible hardware" nor "MTP USB Driver". When I tried installing "MTP Device", I get an error "The install class is not present or is invalid."

Were you ever able to get this working on your PC?

Yeah, and it's been a while so I don't remember exactly, but I think it was a different cable that made it work.
I've switched to a Droid Turbo 2. The 5X didn't have enough battery life for my usage.

thanks

If you have other android devices that is working on your PC, you'll notice that the driver used is the "wpdmtp.inf" you can get it on your 64-bit Windows on this location:
"C:\Windows\WinSxS\amd64_wpdmtp.inf_31bf3856ad364e35_10.0.16299.15_none_42867195f7d5106b\wpdmtp.inf"
Locate this file via device manager and choose "MTP USB Device"
And viola! You can now transfer files again in your Nexus 5x!

I am in the same boat but my PC stopped recognizing my phone at all. PC will see all my other devices including my pixel 2xl. But every since that Nov update I believe my PC's and diffet cables does not show up at all. Have read all the threads and so far nothing has worked for me.

Did you get it working again? I have 2 other phones working fine but the nexus5x disappeared and cant get it back. Even deleted the cache and the data for the System apps named "External Storage and Media Storage" as some suggested. Shows up as unknown device now.

Nope, was never able to find a fix. If you do please let me know.

Yes I got it working. Since longer USB cables only shows unknown device I installed android development system and it made no difference.. But I had a 6inch charging cable that came with my power brick and I tried that and viola the Nexus showed up.. Not as a nexus 5x like before but as something like romaster composite ADB interface or something and I was able to flash TWRP recovery so now I can at least get access to it. Backed up the memory to a flash drive.. Have not flashed SU or anything yet but that should not be a problem with TWRP installed.. And like usual it takes a few flashes and rebooting into TWRP for it to stick other wise the recovery goes away.. Still dont know why the longer USB cables make any difference.. I even tried it out on a USB extension socket which is a 20 foot long USB extender and that also works.. So it must be something else like when I had the MB changed the adapter I was using did not work for data transfer.. Might be using some wire that is missing in the longer cable..

USB error PLEASE HELP!

As regards the attaching of files, you have to have a minimum number of posts to be able to do that.
As regards the USB, be a little more specific like what you are trying to do, which ROM you are running, whether you are rooted, what happens when you connect the phone to PC etc which will enable the members to help you.

There could be several reasons for this, but lets start with the basics.
Have you tried a different cable?
Have you selected File Transfer (MTP) from usb options?

I get a windows sound like its connecting then in the bottom right where the time is next to that is a root sign then I get a pop up saying exactly.....The last USB device you connected to this computer malfunctioned and Windows does not recognize it. Recommendation.. Try reconnecting the device. If Windows still does not recognize it, your device may not be working properly. When I go to the Device Manager/Control Panel it doesnt do anything. I've tried to add adb to the path but maybe added it to wrong path now it won't come on. If there is a work around maybe to re-add to right path. Device Manager was fine before I added adb and added path as per internet search. Device Manager before would say something like error 39. I've tried MTP that doesn't get it to open up either.

I cant even root for the life of me now, Im on 8.0, I'm trying to just root the phone and to start the computer has to recognize it I understand but it won't, with my Oneplus 2 was fine,(I'm thinking maybe phone doesnt have the drivers built in to the file system, you know when you plug in and turn on MTP it shows the drivers app for Windows?) the only thing it errors plugging in.

On my son's pc running windows 10, I didn't have any issues connecting my OP3 to it and viewing files, nor did I have to install any drivers, same for Windows 7.
Hook phone to pc via usb cable.
Pull down notification bar and select "File Transfer" from usb options or go to Settings and search USB and select USB Preferences > File Transfer.
Browse phone from Window's file manager.
If still having issues, you can try and install Oneplus USB drivers, reboot pc and see if the phone can be recognized.

For some reason it's working now don't know what the problem was or even if it was something I did. Either way it's fixed.

If you are running Win 10, you will have to disable driver signing before the correct drivers are installed. May be that was your issue.
