[Q] Connecting EVo 4g to the computer - EVO 4G Q&A, Help & Troubleshooting

Im trying to root my Evo 4g but it wont connect to the computer. When i plug it in it starts charging but i cant find it on 'my computer'. I made sure it was set to disc drive. i have tried different cords and ever different phones with the same cord. the other phone will connect just fine.. i have tried downloading several different drivers but none work. i tried doing a factory reset thinking it was a software problem on the phone. my last theory is that the port on the phone is bad. but the phone still charges so im not 100% sure about that. any ideas on what else i can do to fix this problem?

Go into Menu - Settings - Applications - Development. Make sure USB debugging is checked.

Also, install HTC Sync, it's on your SD Card by default, and then uninstall it, so the drivers for the Evo are on your computer

Has your phone been rooted and flashed to another rom?

Sometimes the usb port for your phone is broken. Mine is so I have to put the sd card directly into the computer using a adapter

Have you made sure your phone is not waiting for a verification that you want to turn USB storage on? I turn it on and then forget to hit "OK" on the popup verification at least once a day.

phone not showing on computer

problem need a little help. as i plug phone into computer i get nothing but charge.Look in my computer and shows up but when click on it it says insert card.can put in recovery and usb that way.....also can adb and phone shows up in command..any help why it doesnt give me the option when i plug it into usb port would be great...
If phone is not shown I believe you are missing drivers. Check your device manager and follow this steps http://unrevoked.com/rootwiki/doku.php/public/windows_hboot_driver_install
Now if you want to access SD card but phone only charge maybe you or someone else clicked "remember this" while selected option "charge only" in past and phone does NOT prompt anymore. What are you trying to do ?

Old thread, same issue here. I wanted to clarify what reflashing a rom would do. I am running MetroDroid 2.2 and usb charges fine.
Should I completely reflash the metrodroid rom?
Hard reset didn't help at all. Different usb cables and ports were of no luck to me either. Cord has snug fit.
bump .
Please clarify the issue for me. Does the USB register at all? Does it charge?
Note: HTC sync obviously only works on HTC roms. AOSP doesn't have this feature, only the disk drive option

USB charges only. Does not register on pc nor does a notification pop up on Evo.
thank you.
You sure you didn't accidentally click the "Don't ask again" option at the bottom? Settings -> Connect to PC and you should have default connection type, which you can change or leave at charge only (the default) and make sure ask me is checked.
I would suggest re flashing your ROM, may be a driver is corrupt.
Also, there would still be a notification if don't ask again was selected. Plus cm7 doesn't have the option to do that, only USB disk drive
Sent by Salvaged Supersonic!
If you're on CM7, you can't use HTC sync, sync only works on sense rom. Though if you can't be detected, go to the HTC site > support > downloads, then re-install sync, because you may have a bad driver.

I thought he meant the drop down menu wasn't automatically popping up when he plugged it in, but now I guess he doesn't get anything at all...
Wait, instead of blaming the phone, have you checked the computer yet? Anything showing in device manager having an issue? Maybe the drivers on the computer are bad or need reinstalled? When I plug my phone into my computer (Win7 x64) Android USB Device -> My HTC and Portable Device -> F:/ show up in device manager when charge only is selected.

[Q] Issue with USB Mass Storage

Last night I was getting ready to do my first root. Was watching the syndicate video, following along.
One thing I noticed last night, is when I plugged the phone in for mass storage, to copy the files to the sd card, I kept getting these two errors.
First, when installing the drivers after plugging the phone in, I was getting this cdc failed. You can see it in this picture...
http://i11.photobucket.com/albums/a183/lardo5150/cdcabstract.jpg
I also kept getting this "scan to fix" pop up for the M drive (my phone).
When I turned on USB debugging on the phone and plugged it in, it seemed fine, except I could not access the M drive on my computer, I would get this error...
http://i11.photobucket.com/albums/a183/lardo5150/insertdisk.jpg
I did some search and decided to try what another user tried, I formatted the sd card.
I then plugged the phone back in, and did not receive the "scan to fix" errors anymore and could access the SD card with no issues, but I could not access it still while in debugging mode.
Is this by design?
Samsung drivers are installed. Got them straight from the samsung site.
No yiu should be able to play with your sd card wgile in debugging
Did you turn on mass storage after usb debugging?
Sent from my SPH-D710 using xda premium
I couldn't access the mass storage in USB debugging for a little while. It turned out my drivers got slightly corrupted. I could do everything else but that. Went into Control Panel with USB Debugging on and found the driver listed as samsung android in USB in Device Manager and hit update driver and let it get it from Windows Update.

I will try that this afternoon.
How about that cdc? Any reason why that is failing?
Same thing.
Says the latest driver is installed.
It never gives me the option of choosing charging, mass storage, tethering like it does when debugging is off.
Any ideas?
Ok, so I found this some other forums.
Seems stupid, but I had no clue.
With my phone, with debugging off, when you connect the USB, it asks you what you want to do.
With debugging turned on, it does not, you have to tell it. Below is what I found....I feel dumb..
"Okay, so if you are freaking out, or can't figure out why your new Epic isn't being recognized by your computer, calm down. Some of you are probably already searching for drivers. Ya I already went through that freak out when I got my Vibrant. Okay, to mount your phone, and have your computer recognize the internal/external memory, do this:
Connect your phone to your computer via USB. Give it a few seconds.
Next, PULL DOWN your notification bar.
Next, tap your finger on "USB CONNECTED"
You then get a message asking if you would like to mount. Tap "mount" confirming you would like to do so.
Enjoy, your computer should now recognize the internal/external memory."

I had the same issue with my epic, try using a different usb cable, the one for the motorola photon resolved all the issues I had with connecting to the computer, I found out thru experience that the stock cable when using windows 7 kept giving me the same error..

Also, I've had success with rebooting both the phone but especially rebooting the computer and plugging the phone back in. Try a different USB port, some folks have 2 SLOW USB ports for mouse and keyboard (mine are in the back lower left...the fast ones are on the right and in front). Most folks have better luck trying rear USB ports (although I don't know why). First, try the computer reboot though...

make sure your phone is disconnected from the computer and then try going into the settings and in the top section that is wireless and networks press more, then USB utilities, and press connect storage to PC and then plug your phone into the computer. had about the same problem and came across that.
You can also try going into your device settings on your pc (samsung/modem) and resetting the driver it seems to get "stuck" sometimes.

+1 to this... its the new way to connect
I put this on my sd card (by taking the card out of the phone) and putting it in a card reader. I flashed the file from the stock recovery and this gave me custom recovery. Then I restored my previous backup. I was having the same issue and FB21 has too many bugs. I went back to gingerbread but kept fb21 modem.
You can actually get MTP working quite simply...

To use USB MTP you have to unmount SD Card first then plug in.

Exactly what error do you get?
Did you CHECK "Don't ask me again" on the window that pops up when you plug it in?
Go to system settings => Connect to PC
There should be a box that you check/uncheck to make that window pop up.
When you plug it in, do you get the USB notification in the notification window? Can you click on it to change the connection type?
Is there any other useful info you can provide?
I had a EVO recently that the usb internals died techs couldn't even repair ... Or just make sure double check you have drivers installed , usb debug checked too
Sent from my PC36100 using XDA
Well thing is,it works on my laptop but not on my PC(WHICH USED to work cus I rooted there) I'm gonna try and install the drivers on pc,the ones I recently used on laptop.
It only charges the phone cus the light is on.but the notification doesn't come up nomore,
I'm on cm7 with tiamat kernel
I haven't had any problems with that ROM and kernel combo.
Have you tried different USB ports on your computer and different USB cords?
I can't think of anything else other than what's been mentioned.
If you have any more info, that might trigger a thought in someone's mind.
Make sure to post again when you figure it out!
I reinstalled the driver and it solved theproblem.
Kinda weird tho cus just because i installed the phone to laptop, pc failed to recognized it(maybe pc got jealous lol)
