device not in device manager

hi
having problems with htc sync but cannot fix this until i at least get the phone to appear in device manager
at the moment, which i plug it in via usb (official htc cable) it charges but nothing shows in device manager so cannot even update drivers etc
running 32 bit win 7
any solutions welcomed
thanks

Once the relevant drivers have been installed, and your phone has been connected as an drive, it should show up under Disk Drives In Device Manager.
Download HTC Sync from here: http://www.htc.com/www/SupportDownloadList.aspx?p_id=312&act=sd&cat=3
Esnure that you have USB debugging enabled:
1. From the Home screen, press MENU, and then tap Settings > Applications > Development.
2. Make sure the USB debugging check box is selected.
After you have installed HTC Sync, turn off the phone and turn it back on again while connected to the PC via the USB cable, and then select the Disk Drive option.

if it only shows as disk drives, then it still wont work.
You should have an 'ADB devices' section at the top (or it might be called ADB interfaces, it's been a while since i did it on 7)
here, the phone should show as 'My HTC'
chances are that windows 7 decided it knew better and went and installed an 'HTC Dream adb composite device' from windows update instead of the ones installed by HTC SYnc
delete those or update manually to the My HTC ones and you should be good.
The disk drives is for the SD card and has nothing to do with the sync at all as far as i know.

thanks for the response, but the device just will not show in device manager
i have tried the above steps
any other solutions

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?

Can't get Nexus 7 to show up on computer

Shows up on my laptop but not on my desktop, have tried back and front USB ports
have uninstalled USB drivers, reinstalled USB drivers (universal adbdriversetup6 downloaded from xda sources)
downloaded android SDK manager and installed whatever USB stuff it had there
used USBdeview to remove any nexus 7 related things and then re-install USB drivers
Cannot for the life of me figure out what's going on... can anyone help me please
When I plug it in my desktop it makes the sound like something got connected... even has the safely remove hardware thing with nexus 7 there, but nothing in my computer
also have tried with/without USB debugging
tried removing my rom and flashing stock etc
Nothing has worked so far

and yes forgot to put in the title but this is for the Nexus 7FHD 2013

Is there a chance you are using usb3.0 port and can switch to usb2.0?
I would suggest you backup, flash stock, and redo your driver deinstall/install on stock. Try to get it working there first. Make sure USB debugging is disable on stock.

tried USB 3.0 as well as 2.0 on desktop doesnt work, shows up as a device on safely remove hardware, and I can also see it under other devices in hardware manager or whatever but doesnt display in computer
USB debugging enabled or disabled on stock doesn't work.. tried going back to stock and doing driver installation etc as well

In device manager are there any unknown devices?

Did you remember to

Driver instal with WinXP
I went around with this problem after both my Win7 laptop and WinXP desktop both recognized my N7 2013 the first time I connected to them. I had no problem dragging and dropping files.
I had then returned the tab back to BB for a exchange for another. This time after setting up the tab and setting the MTP file toggle and USB settings correctly......The Win7 laptop worked find and recognized the N7 just like it did on the first tab. But now the WinXP desktop did not work and only saw the N7 as a ABD device.
You may already have the correct drivers (if not those are available here in several posts). You just have to direct windows driver update to the correct place for the MTP driver. Here is how i did it.
1. Open up the Device Manager on your PC and locate the Android device it sees. Select the update driver option and you get to the "Welcome to the Hardware Update Wizard" screen.
2. In this window it asks "Can Windows connect to Windows Update to search for software?" Select the 3rd option ' No, not at this time"
3. In the next window "This wizard helps you install software for...." Select the 2nd option "Install from a list or specific location (Advanced)
4. In the "Please choose your search and installation options" window... go down to the bottom and select "Don't search, I will choose the driver to install" option.
5. Now finally the window we need..... "Select the device driver you want to install for this hardware" The "show compatible hardware" button should be selected...if not check that box. You should see 2 choices in the "Model" area..... Google Nexus ADB Interface" and what we need to select " MTP Device" click on the MTP Device and hit next......it should install and your Nexus 7 should then show up properly.
Hope this works for all that have had a hard time as I did....I just found it odd after getting a replacement N7 my XP desktop did not recognize it as it did to the original one I used the day prior.

Just go in settings then storage and then computer usb connection by opening preferences in storage and then make sure mtp is checked.

Thank you guys SO MUCH for the help... I actually just returned my unit to staples because those POS wont give me a price adjustment vs google play

If nothing else here has helped you solve this issue, check my thread, it should be of some help to you...

I'm having an issue where I can connect to my laptop in debug mode, but I'm not able to connect in the MTP mode with debug turned off. I expected to be able to mount the device storage in either mode.
Is that correct? If so, any ideas? I do notice I can't seem to get the MTP driver to stay in device manager.

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.

Cannot connect Note10+ to PC

When I connect my Note10+ to my Windows 7 pc, I don't get ANY acknowledgement a device is connected. No beep, popup.. nothing. I did install the Samsung USB drivers, but that's not the issue because there is absolutely no unrecognized devices in the device manager. NO reaction from the PC. Are there any windows services that need to be enabled? Because I do have minimal services enabled.
I can connect a thumb drive thru the same 6ft cable which is kind of old. But not the phone. Could the cable still be bad or not new enough, or short enough? Tried the rear ports also. I don't have any other cables at the moment.
USB debugging is enabled and the phone is set to Transfer Files. Restarted the phone and PC.
Just no beep or popup or anything when I connect the phone. However the phone does charge. The phone is only a month old. Maybe a bad phone port? Is the Note10 USB-C port generally kind of stiff when you first connect the supplied power cable? I never tried to connect it to the PC before.
Thanks.

Try another cable/port.
See if it shows in disk management, hit rescan drives.
Try reloading the drivers manually or automatically depending which you tried first.
If you have SmartSwitch loaded on the PC you should already have the drivers.
Closely review what you disabled and their dependencies!!!
Check Event Viewer for errors.
I have a PC running on W7, my 10+ pops up effortlessly. It could be the C port PCB but don't jump to that conclusion yet. Try a flash stick in it.

Thanks. I have to borrow one. The thumb drive works with the cable, but not the phone. Strange. Connect a thumb drive to the phone??
Going thru my services now. I should get a beep or something.... then I worry about drivers if need be. I scanned for new hardware in device mgr and expanded all trees anyway... nothing. Scanned drives in Disk Mgt... nothing.

If I go to the Samsung desk at BestBuy, will they help free of charge?

Connected thumb drive to phone THRU THE SAME CABLE... Notification says USB Storage Connected, and I can browse through those files.
How do you unmount the thumb drive.. just disconnect the device? EDIT: I got it... "Unmount" in Notif shade.
So the phone port should be good then? Thx.
All I want to do is some ADB commands to disable Doze and remove bloat.

I just pull it, the SD card I unmount first.
I don't think it's a port issue.
Try disabling ie turn off Developer options.
The issue seems to be on the PC side.
Services can have a lot of dependencies with far reaching consequences if disabled.
If in doubt renable, reboot, try again.
Something should be logged in Event Viewer when you try to connect.
Could be a driver issue.
On the 10+ you should get a popup asking if you wish to connect if not the 10+ isn't seeing the PC.
Try another PC if possible.

Clear the 10+'s system cache.
You disable Developer options?
Try enabling it again.
Hard a reboot (not factory reset!) on the 10+
A settings issue on the PC? Event Viewer, security.

I wiped cache partition. nothing.
I should have described the silent notif better. When I connect the cable to the phone (even if not yet connected to PC) the silent notif says:
"Charging connected device via USB" and when I click on it, there's two menus with radio buttons.
First menu: "USB Controlled by:"

3) MIDI
4) Transferring Images
5) Charging Phone only

Does ADB tools require Microsoft Visual C++ 2015 redist.
Keep getting error: "api-ms-win-crt-runtime-l1-1-0.dll is missing error" when I type adb devices
And to install Microsoft Visual C++ 2015 redist, I need to install Windows6.1-KB2999226-x64.msu and that will not install.
First time ever feeling the pain of still using Windows 7.

It's grayed out because of the Developer options think.
I'm using the "transfer files" option. I don't get those options, it just asks if I want to connect.
My 10+ is a stock AT&T variant running on Pie.
I haven't used ADB so not sure. If Event Viewer is showing it as missing... you probably need the library. Side by side errors used to be common on x64 machines, missing MS library.
Canon did that. The Developers already had it on their PCs and forgot to include it in the install bundle

W10 is a dud. W7 should work fine; it shouldn't need any of that to transfer files.
Android 11 may be the perp... I don't know, sorry.

SUCCESS! I used the 15 Seconds ADB Installer as describe here: https://www.droidthunder.com/adb-installer/ Worked like a charm.
The manual ADB platform tools did not work (api-ms-win-crt-runtime-l1-1-0.dll is missing error) probably because I didn't keepup with my win 7 pro system updates. Always hated MS updates because when you reboot, there's other issues you didn't have before or there was more unessessary BS running in the background..
I know windows 10 is a dud. That's why I'm STILL on 7. It's poorly designed and not a true desktop OS. Thanks for all of your help. Wasted a whole day on this.
