[Q] Laptop won't recognize phone

my computer does not recognize my epic anymore. I have the required drivers for it , but it keeps on popping up as an unknown device. I also made sure usb debugging was left unchecked. I have been trying to connect for a few hours now but still no luck.

What OS are you using on your laptop? If it's windows go to control panel and your programs add/remove (will vary depending on windows version) scroll down to "Samsung USB drivers" and click "uninstall", then reboot. Go to here and download the most recent usb drivers again. Plug in your phone, then install the drivers.
Post your results. Most likely it is not your phone, its a driver that has become corrupt on your laptop. Other possibilities are a bad USB cable or port on your phone.

I'm running windows vista. I tried uninstalling and reinstalling the driver already, still no luck.

Have you tried a different USB cable? Did you make any changes to your phone or PC just before it stopped recognizing it?

I had to use a usb hub with a power source for my laptop to see the phone.
Dell D620
Samsung Epic 4g

same thing on my pc. I keep getting USB Mass Storage Device Failed Error Code 10. started happening after the first push of froyo. im running Windows 7. very frustrating.

Epic thread revival!
I'm having a similar issue with my Epic. Both my laptop and desktop will recognize my phone as "Samsung CDMA Technologies" However, I can't do anything with it except charge. What's particularly bugging me is
A) Wired (USB) Tether won't work
B) Can't mount SD card through the phone
Laptop Specs:
Windows 7 Ultimate 64bit
Linux Mint 11 64bit (I'm having the same problems with Linux)
Phone Specs:
Epic 4G (SPH-D700)
Syndicate ROM Frozen 1.2
EG22 Moden
Genocide 2.0 Kernal
Here is what I've tried:
Toggled USB Debugging (both on and off)
Used Premium Micro USB cable in addition to stock cable
Uninstalling and Reinstalling drivers
used different USB ports
rebooted phone and computer
It should be worth noting that my phone seems to think everything is a-ok. Wired Tether app doesn't report errors, and when I mount SD card, there is no error either and the phone proceeds with the "USB storage in Use" message. My computer (regardless of which OS I boot) seems to think my phone doesn't exist, unless I'm doing admin type of things, such as flashing via Odin.
Normally, when I had my previous Epic (SRF 1.0.1, EC05, Twilight Zone Kernal), before it was stolen, Wired Tether worked perfectly, especially with Linux (connect as "AutoUSB 0"), and I could mount my SD card.
Suggestions?

Go to control panel and have it update drivers from Windows Update. Takes a long time to get them all.

I get the feeling it's more than a simple driver issue. I have the same problems with Linux, and linux has native drivers. And Windows Update is useless. It can't even find drivers for my fingerprint reader. Nevertheless, I will try it next time I'm on my laptop. Windows on my desktop is fubar.

I had the same issue with my pc.. I ended up using an old vista lapptop and everything worked perfectly.. sometimes these pc's just straight out don't work with these drivers.. wish I could help you out more man

Maybe dialing ##8778# and selecting modem mode under the usb section will help automtically install drivers.. see if that works, it helped me out for the whole epic to boost mobile process

It's already on Modem mode... I'm going to try PDA mode.

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.

flashed ICS rom now phone cant be recognized by computer

ok basically phone wont go into mass storage mode when connected to computer and it isnt recognized by odin or the the computer at all and let me get all these out of the way before im asked
ok first yes driver are installed properly i even installed kies twice and just the drivers from the samsung website to make sure i wasnt messing up somewhere

i also tried doing a nandroid of blazer rom and getting back to the gingerbread just so my phone would be recognized that also did not work
and then..
i just now bought the mobile odin app and tried flashing the stock eko2 kernel this did not work either
and then...
ive used the original USB cord and the one i bought to day as well as several different computers just to see if the pop up as recognized with show but nothing happens my phone seems like its no longer capable of going into mass storage mode
and then...
moved this here hoping someone has has this issue hopefully you guys can help ill be up all night so feel free to resond whenever thanks guys

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)

[Q] Connecting EVo 4g to the computer

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.
