My computer does not recognize Evo?

This must be asked a billion times a day, but I can't find an answer. Is there something simple I'm missing? I hope?
My computer's Device Manager in windows shows "My HTC" as a device. The drivers are there. It shows "USB Debugging" on the phone. But when I click on the drive letter for the phone, it says, "please insert a disk." I have the default set up to mount as a disc drive on the phone. But I no longer get prompted.
wtf?
Appreciate advice. TIA.

im in the same boat u are, cant really seem to get any help on it either.

Shouldn't be required, but install HTC Sync and restart.

Having the same problem. Reinstalled HTC Sync, restarted phone, even tried http://forum.xda-developers.com/showthread.php?t=695243 that stuff, but to no avail..
The phone still charges and windows shows the drive, but it is greyed out.

Few suggestions.
1. Click menu button on your phone and select the connect to pc option. Make sure the Ask Me checkbox is checked. Check your default type as well to see if it is set to disk drive, charge only or some other option.
2. Make sure that PC synchronization app is not disabled by any task killer apps. This app is needed to allow the phone to mount as a disk drive.
3. The Windows drive letter assigned to your phone may be conflicting with some other drive mapping. To fix it, right click my computer icon on your desktop and click manage link. In the computer management screen, go to the disk management icon. You should see your phone represented as a hard drive. If not, your pc is not recognizing your phone for whatever reason. If it is shown, right click it and reassign it to a different drive letter.
Good luck.

So my computer does not recognize my Evo and my Evo doesn't display a notification corresponding to the choices of the USB capabilities. However, this is a fairly new and I am not sure if it is the rom I was using, the fact that I connect to computer that does not allow drive access for unauthorized devices, I deleted a crucial file (pc sync) or there is an issue with the phones port. I have tried everything from using other computers to cables to simply buying a card reader with a usb port and pushing a new rom onto so I can flash it to my phone. Now I'm running the new Team Nocturnal RS 4, props guys. I still am unable to work out my usb issue. So I think I might have to unroot and exchange the phone through sprint or live on a card reader (which means no late night coding for me ). Anyway, I know this question is asked a lot, but could someone direct me to the newest stock RUU, please. Also I would like to re-apply pc sync on my phone if that is the root of the issue. Can I have ideas on how to complete this?
Also, I heard sprint is not carrying the classic Evo 4g, is this true? If so what a rip...
Thanks in advance, you guys are awesome to deal with us novice all day.

Ok guys,geez,right click the drive and select fix partiton issues,thats what i had to do,Sometimes windows(the worst os yet)decides to be a ***** and not recognize the drive.

[Q] MTP USB device error

I'm using Xperia Arc but yesterday my phone didn't connect to my laptop. The error announced that "MTP USB device can't install". I change from MTP to MSC but my SD card didn't appear in my pc althought all drivers were installed So sad.
I had search in google but just have question for SAMSUNG Kies not Xperia
Anybody can help me?

you can connect your phone in Mass storage mode, but you need to open the notification page, by sliding it down, when you select the option, a new page opens in that you need to select the "connect memory card" option. then you will be able to access it on your pc.
for the mtp issue, try and install this Media Transfer Protocol Porting Kit , its there on the microsoft website.

I had the same problem with the MTP Drivers.
I tried using SEUS for the drivers but it wouldnt work.
So i got into SEUS and reinstalled the current software and then after installation i connected Arc to the computer with MSC (MTP) and the drivers were installed.
Suggestion: Reinstall your software directly from SEUS or SEPC.
My conclusion is that the rooting did change or did something with my device.
If you need the drivers and dont wanna reinstall your Arc here is the drivers that was found through Windows 7 (64 bit).

What about 32 bit please?!
I can't install the MTP drivers as well...

[Q] Help! - New to Android, cannot transfer files via USB connections

Hi all...I am new to XDA forum, but have been browsing in the trove of information to help with my problem. At the end I am resorting to posting a new thread to hopefully help me in resolving this problem or provide a good explanation why it does not work.
Problem: I am trying to use the USB cable to transfer files to my SD Card. (I am not sure what reason, but someone has informed me that either Samsung's proprietary software Kies does NOT work, you can only transfer using Samsung KIES Air...which is painfully slow.)
Now here is my situation:
1. I have a Bell Canada - Samsung Galaxy Note-2
2. The Phone has been unlocked and rooted (using Odin)
GOAL:
- I don't care if I need to transfer files to the SD card, and then sort the files out afterwards on the phone.
- Primary goal is to allow me to transfer files (music, mp3, etc.) via USB cable.
Your help is greatly appreciated...in providing some sort of clear cut instructions or directions.
Thank you in advance.

I know you didn't ask for this, but could you possibly use Airdroid? It has always been reliable for me and honestly it's my best solution for myself because we don't actually have UMS anymore, sigh.

Airdroid Vs. Kies Air
Thanks for the response and recommendation.
So is Airdroid? better or the same as Kies Air?

I've never used Kies so I can't say!
But basically, you download the app from google play and go to web.airdroid.com and you type in the code that you see in the app. From there you can read your phone's text messages and transfer files and do other things via your wifi connection. File transfer on my (good) wifi network is fairly fast (about the same as using a usb cord) and it's good for me because I personally use Ubuntu and Chrome OS, so the USB storage options don't work or don't work well.

usb driver
All you need is go to samsung website and install the usb driver. You should have an option to do this during the kies installation too.

Just in case, make sure that MTP is checked in USB computer connection.
*Settings>Storage> Menu button>USB computer connection> check Media device (MTP)*
I know it may seem obvious to some but it does get overlooked sometimes.
Cheers!

In regards to the downloading the 'Samsung Driver' I have already attempted that, and with no luck of cooperating. Under 'device Manager' in Window 7. The listed device when I plug-in the phone is "Qualcomm CDMA Technologies MSM" with an exclamation mark. I have been trying to try the driver files so I can 'direct' the appropriate drivers file. But no luck locating it. The Samsung Kies installation mention that it has installed, but no luck.
MTP Option:
In regards to the MTP, I do not have that option available on my phone, the only thing avaliable is through the 'Developer option -> Checking/Unchecking USB debugging'
Please Help! :crying:

I have download the driver form the Samsung.com website.
Now, It doesn't technically allow to choose my specific phone model, with my carrier (BELL), so I went with the closest ATT.
I have located the folder with the USB driver, and force window to look through it.
But still windows says it cannot find the correct driver for my device....this is getting frustrating.
HELP...help...help...

That is odd. Do you have a Storage category under System Settings? It should show you available space on internal and sd storage. What happens when you hit the menu button? (button to the left of the home button)
When you connect your USB cable, do you get a notification that says "Connected as a media device"?

Heres what you do.
Make sure you have current samsung usb drivers. Redownload just for fks sake.
Yeah idk wtf ms prob is but its got issues with samsung phones.
So ok drivers gtg?
Plug in phone
Wait for annoying pop up.
Leave phone pluged in and on restart computer.
You should get the all clear but first it may give you the cant recognize drivers thing give it a min should work.

Basically just keep going back and forth witj mtp and mount you should kick it in.
And you may need to restart computer.
Sgs3 easy wotks pretty good for me.
You gotta make sure you have the microsoft mtp update installed.
Pia I know.

In regards to your question. Yes It is odd....'Yes" I do have a storage category under System settings. I do see available space on internal and sd storage. BUT Nothing happens when I hit the menu button. Absolutely nothing

I'm sorry. That is my bad. It looks like those options are not available on the stock rom. I thought they were. The option is there on CM.
It looks like it is probably a driver issue. If your computer is not recognizing your device when it is plugged in, it could also be a bad USB cable. If you can try a different cable, see if something different happens when you plug in your phone.
Worst comes to worst, you may just have get a card reader and connect your sd card to your computer that way.

1. Is cable good? It may be sending incomplete signal. The fault could be your device's usb port or cable or pc usb port.
1a. test device with another known working usb cable
1b. test cable with another known working device
2. Is PC port good?
2a. Plug a different, known working USB device into port, do other devices work?
2b. Plug device into another usb port on PC, not into usb hub or front usb ports.
2c. Does it successfully connect for transfer with another PC?
3. Is driver good?
(This is most likely your problem, but a bad usb device, cable, or port can make it more difficult to troubleshoot. )
3a. Re-download driver. BUT BEFORE YOU DO...
use a different browser to download or delete your browser's cache. (Attempting to redownload may just be grabbing the already known poor copy.)
3b. Run Windows Update after driver is installed.
If still having problems.
Search for, download, and run the portable program usbdeview. Attached USB devices will be highlighted. See if it shows up to the system and what it is being recognized as.
It sounds like either a bad driver install or conflicting program/setting.
Turn off antivirus temporarily to rule that out.

Problem with connecting to my PC

Hello, everything was working fine, i always use my phone as a flash disk (i mean im not using HTC Sync Manager, but i just copy things to my phone like it was a flash disk) suddenly yesterday my phone was detected (the sound when i connect it) but instead of Storage there is just a "CD-ROM (F HTC Sync Manager" and in my Device manager there is the MTP thing with triangle and error 28 (file not found or something like that). I tried many thing which i found on the internet but nothing worked... Please help

This isn't a worthwhile statement, unless you actually state what those things actually were. Otherwise, we can only waste our time guessing what you did or did not try.
In Windows Device Manager, select the option to update the drivers, manually select the drivers, and pick the generic "Android MTP" drivers (or some similar name). I often have to do this for my PC to properly "pick up" my phone's internal storage.

USB conection problems, faulty hardware?

my a2 lite does not connet to my pc, I have installed drivers, put it on usb debug, but my pc does not recognize de phone, I have tried different usb ports and cables with no success, it does charge eventually with some cables, but I don't know if this is hardware problem or there is any setting I am missing, it does not give me any choice of chosing the usb kind of conection
it is a new phone just prepped for everyday use, not hacked or modded in any way
USB OTG is working but only reading, I cannot write in external usb drive with es file explorer, or the includer file aplication, it says unsupported operation
any help?

Set hardware id in the adb_usb.ini file perhaps

thank you, but I cannot acces from adb as there is absolutely no conection from my computer, it only starts charging but as if it were just a charger, there is no usb mode options avalaible y my phone, and the pc does not recognize anything conected
I have tried to connect with another computer with the same results, it only gets power, but no data comunication whatsoever

as nobody gives any clue or info about some hidden setting, I must assume this is another case of bad quality control in xiaomi products, I will check with the seller

Did you specifically set file transfer mode via the notification drawer or left it on charge only?

the phone does not detect either that it is connected to a computer, so the notification to select the mode of connection does not even show
I have tried usb otg and I can read fine but I cannot write at all in a pendrive
I have installed also an sd card as internal memory and have storage errors all the time so I have removed it
I have tried also conection in fastboot mode but the computer still does not recognize anything connected
I have uses several cables, usb ports and even 2 different pc with same results
My only guess is that there were some hidden config setting that is messing with the phone, that's the reason I am asking before going to the seller.

Seems like a broken USB pin then

an usb pin should not affect internal sd memory, and usb does not work like water pipes, one pin data in one pin data out, they need both data pins for reading also, so as it can read from pendrive the problem is somewhere else, not in the connector.

This could be a hardware problem. Have you tried to connect it to another computer?

I have already tried on 3 diferent computers with same results. The only diference so far is that it actually does not read either the content of a pendrive connected through OTG, the first day it read it, now it only detects but reads nothing.
Also when sd is configured as internal memory, instead of reading internal memory, that seems to be the normal result, I can read only the sd card with android file explorers

I have the same problem.
No connection data with pc/mac, it only charges.
I'm italian and like many other italians, I've also the problem with Sim slot 2 with no connect..

F**k, this phone starts to look like a piece of garbage I dont connect to USB, I dont use SD not 2nd sim, so I did not experience these issues, but, f**k again..

Have you tried rebooting? Press the power button for 15secs. to power it off. Use another cable, use another PC, make sure the cable is plugged in properly... bla bla bla. Oh, have you tried placing the phone into a dry rice bowl? Haha (sorry, I had to). I'm sure you've tried it all.
So, I have not much to say. Only that I had a similar problem with a Moto G after I flashed a LineageOS ROM. It worked fine before, but with the new ROM, the USB didn't work at all (it could only read OTG). It was stuck in the "charging" mode. No notification nor option to turn it to file transfer. The PC didn't recognise it at all, either.
Solution? Initially, I turned on USB debuging option and the PC saw the phone (on windows device manager, it was there, but not on MyPc). It was some advance. I can't remember if adb detected it.
Final solution? Luckily my phone was rooted and had a custom recovery, so I could easily flash the same ROM from the TWRP recovery and everything works fine now.
You might try using Xiaomi's flash tool to try to flash the orginal ROM again IF the phone is recognised by the tool (try if it can see the phone) http://en.miui.com/download-354.html
And I suggest contacting Xiaomi for a warranty claim if needed, 'cause it looks like a harware problem (a pin the the microUSB port issue). But be ready to answer the questions posted above several times haha.
Good luck!

I have done all your sugestions previously, even reseting phone with a new gmail account so no config setting from other phone could interfere, I have also tried fastboot, but although phones goes to fast boot mode the pc does not recognize connection either
it is not an usb pin issue, tried 6 cables, 4 computers, 10 or more usb 2 an 3 ports, I am negotianting in aliexpress a refund, we'll see
If I go into recovery mode with power vol+ a broken android appears.

I don't know if you already did this, but try using a PC with Linux (you can use Ubuntu without installing it on the PC, then install the fastboot package).

Hi,
I had no problem with fastboot and adb with Mac!
Phone recognized by the machine and do transfer boot.img for magisk...
Now I Win!
I can see the internal memory with Android File Transfer (Trasferimento File Android in italian!) - this is the link https://www.android.com/filetransfer/.
My version of Build is V.9.6.8.0.
Solution:
- Connect the phone to pc/mac;
- Go to: Settings -> System -> Developer Options -> Select USB Configuration -> select first "Charge" and then "MTP" (Media Transfer Protocol)
- The system recognize the phone!
[for italian, like me, andare su Impostazioni -> Opzioni Sviluppatore -> Seleziona Configurazione USB -> scegliere "Ricarica" e poi "MTP" (Media Transfer Protocol) ]

Where are you from? Where did did you purchase the phone (the actual store, is it in China)? Depending on where are you from and what country did you buy the phone from, by law, you'll get manufacturer warranty. So, any "official" distributor in your country will have to provide a warranty solution for you. If Ali Express is unable to provide you with a solution, look into that.
