Or try a different cable, the one that comes with the phone is crap.
I have the same problem. With trial and error I found some very bizzare solutions.
1: choke a turkey and slam it on the pc box.
2: when the pc detects but dont show it as epic, go to device manager and under usb select the "unknown device" and right click and uninstall it. Unplug the phone and refresh the device manager. Then remove tge battery and put it in again. Replug the phone and it will detect it correctly. If it dont, redo the steps. If it fails on the 5th attempt, well you plug the epic, hold it upside down (meaning face down) and keep it like that. Dont turn it over. Weird but on my pc, when it detects it and I flip it upright, it looses the detection, when I flip it the other way.. It detects it. I can flip all day and it detects and undetects. Weird but it does it. Maybe g sensor doing sonething causing ti undetect?
What usb cord are you using? I had that problem too. The only way my laptop could read my phone even after drivers were installed was through the OEM samsung cord.

I agree with Leatherneck. The cable that comes with the phone is great for charging because its long, but as a data cable is sucks. You can try other usb ports; in my experience, the stock cable only works directly off a motherboard header, no hubs or front-usb ports. Get on ebay and find yourself a better cable. I got one for $2 shipped here in the states that is much thicker and will work regardless of what port I plug into.
I use the stock usb cable. Never had issues.
The command prompt would not recognize my cellphone when I did the One click root. What I did was restart my cell phone and on the computer bring up the Task Manager and went to the processes tab and ended the process for "adb.exe" and re ran the run.bat.
And then it worked fine for me.
Sometimes the one click gets hung up trying to find the phone. Just unplug the cable from the phone, plug it back in, and it should continue on.
If you can't root with one of the quickies, try downloading superoneclick (easy way to get necessary files, plus they are updated) from forum.xda-developers (dot) com/showthread.php?t=803682 and follow this guide thetechjournal (dot) com/electronics/mobile/how-to-root-the-motorola-droid-2.xhtml
If your phone doesn't have cp like mine, then just replace "cp x y" with "cat x > y". If you continue to have problems with this method because of windows detection issues, try downloading a livecd of a linux distro like DSL, puppy linux, or ubuntu (ubuntu worked for me, not sure if the others will).
Was usb debugging on? That's what stalled my root the first tim I was on dk28 lol
Also, the stock cable is the only cable I use on the epic and never have problems

You get cp when you install busybox, which requires root. Using cat and a redirect is just a roundabout way to do the same thing as cp.

Before you run the one-click go to your task manager and under the processes tab stop adb.exe. Usually works for me.

But how do I get busybox onto my phone without a workaround if cp doesn't exist on the phone in the first place? Can files be pushed directly to the phone memory after remounting /system as read/write?

"USB Device Not Recognized"
I have searched for so long trying to figure out what's wrong. I'm out of idea's on how to fix it, nothing will recognize my Evo.
Tried on 4 different computers, two of them running 7, one running xp, and last running vista, all say the same thing, computers not the problem.
Downloaded htc sync, disabled/enabled usb debugging, restarted the phone many times, restarted computers, and even changed the default usb connection to HDD and HTC sync.
I rooted using the idiot proof guide and used the Sprint Rom he linked in the guide. Would love some help. Thanks!
Try downloading the auto sync app in market
And let me know what happens.

Just tried that and still not recognizing it.
Which HTC Sync did you try? I think the latest is 2.0.40
http://www.htc.com/us/support/evo-sprint/downloads/
set the EVO connection type to HTC SYNC and USB DEBUGGING ENABLED.
Assuming you've used ADB, what response you you get from
ADB DEVICES at the command prompt?
you should get something like
C:\>adb devices
adb server is out of date
* daemon started successfully *
List of devices attached
HT05EHL10353 device
and we will know you have a good physical connection to the computers. If it doesnt show up, try a different USB cable....

Thanks for the help! I checked for my device in ADB and it does not list it, so i guess my cable is probably bad. I'll go out and buy another and hopefully that fixes the problem.

When i connect my phone in recovery mode, it still just says device not recognized, so i can't really do that.
Sorry but bump, i relly need help with this.
It still says unknown device when i try to connect my phone in recovery mode.
Go into your computers device manager and uninstall the device and htc sync, then reinstall sync and make sure usb debugging is on then plug it in
Edit: sorry, go into the device manager with it plugged in. if its not there (should be a yellow or red triangle next to it or neat the to as a HID) them it could be your cable or phones port.

I think you need to pay closer attention to the guide, because this statement makes no sense in reference to the guide.
The guide is helping you install ADB drivers, you don't need to do anything in ADB while your phone is in recovery in that guide.
Could be wrong, but I'm still fairly certain that the guide will fix your issue, because I had the same problem.
It's as simple as you do not have the correct, or any ADB drivers, therefore your phone is not showing up as a device under ADB. Once you have the proper drivers installed, your device will show up.

I followed the simple guide step by step.
When i boot into recovery mode i end up with this in the picture.
His recovery mode shows an Evo with a little exclamation mark next to it, i'm guessing what i got is still recovery mode. But still if i plug my phone in my computer still says unknown device, so i can't install ADB drivers.

You just have a different recovery. Once you are in recovery, you don't need to do anything else on your phone specifically.
Instead, connect your phone to your PC via USB if it isn't already and open up device manager on your PC and follow the rest of the guide.
Edit: Where does it say unknown device? In Device Manager?

It shows up in usb controllers instead of other devices as he shows in the guide. If i try to update the driver it just tells me it's already up to date.
>Sorry yea it does say unknown device in device manager.
Gotta bump, would really love to just fix this instead of driving 30 mins to a sprint store.
So i followed the guide for installing apb drivers, but even in recovery mode my phone still shows up as unknown device in device manager.
Ok, well I just ran into this myself on my secondary computer. Have you tried a different USB port on your PC?
My front ones were giving me unknown device, but as soon as I plugged it into one of the ports on the back of the mobo ADB showed right up in device manager.
Factory reset it and get it exchanged.I belief is the SD card failure issue.

I have the same problem and posted this question on 3 forums including the HTC support forum and nobody has been able to find the correct solution.
I know the cable and the port is good because I can connect my Samsung Moment to it and it works perfectly. On the Evo, I've downloaded the latest HTC Sync from the official HTC site, tried the one on the microsd card, checked and un-checked USB debugging, and still it doesn't connect.
The Evo won't connect to my Win 7 computer at home, Win XP at work, but it will connect to my daughters computer which is running Win XP also (all 32 bit).
I bought this Evo from Best Buy exactly 28 days ago today. Do they give you 30 days to return it, or is that only the Sprint store?
They do give u 30 day trial.go get it exchanged or...........

Have you tried reflashing Odin?
Here's a link to *OFFICIAL* SPH-D700-DK28-8Gb-REL.tar.md5 (Froyo Stock). Just remember to turn off the phone, press 1 on the keyboard and power up once it says Download connect the usb to the device, open up odin (which you already have and it should see COM5 (or some other com number), load the pit file and use the pda section to enter in this tar (heads up once you download the file from above just remove the .md5 from the extension and leave it as .tar)
Good luck and hope this works for you.
I have installed and reinstalled the samsung windows drivers about four times.
My phone has not yet been activated and I'm not sure I'm going to attach it to service for the foreseeable future instead of possibly using it as an ipod touch with a keyboard.
I have connected the phone to my laptop one time. I feel asleep with the phone searching for drivers (the drivers had already been installed but the status bar message said it was searching anyway) and when I woke up it seemed fully connected. I was able to cwm3 root the phone but bricked it I think by putting an ext4 filesystem on without moving immediately to an ext4 rom.
I've restored it to stock and through wifi updated it over the air to ec05
Ever since then I have never been able to connect using any of the usb ports, trying two different usb cables, the oem and a generic micro-usb cable and using either windows vista or ubuntu on this computer.
Clockworkmod reports that the phone is not connected and I am not able to see the phone as a hard drive when I set it to mass transfer mode.
In download mode, odin is able to communicate with the phone reliably.
I've repeatedly tried all ##8778# settings and I've set debugging mode off and on. Device manager shows that the phone is connected to port COM7.
Is it possible that the activation program is preventing the USB connection? I would think not because the activation status has not changed since the one time it did connect, but I'm at a total loss for any explanation.
My next step is to try another computer but I don't have one handy.
Is it possible to root a phone only through odin, or to put a file onto the sd card that can root without the use of the computer?

While it isn't JUST a root that you are doing, as stated by budderocks, you can flash the pre-rooted EC05 tar file through Odin, although it will require you to reinstall any apps you currently have. This will start you out with either a stock(ish) setup, with root already included (not sure about Clockwork though), or you can use the one modified for the ext4 filesystem with CWM 3.0.0.6 included which will convert it to ext4 the first time you boot into recovery.

I have been through this myself and came short of beating my head against a wall before reading that it "may" be a cable issue.
Well, after tyring everything else, (because it couldn't be something as simple as changing to a different cable, right??!!) I pulled out an old cable from my Blackberry days and BAM - my laptop searched for and loaded the needed drivers and sees my phone everytime I plug it in now. I have also used a cable from a friends phone (not a Blackberry) and my laptop still sees the phone so I'm not advocating for Blackberry cables specifically.
Bottom line is - the Samsung cable is a piece of crap. It may work for a day or a month, but it will soon (for 98% of Epic owners) become nothing more than a charging cable before long.
Try using a different cable (not a Samsung model ) and see if that works. If so, then ODIN/one-clicks become your best friend(s)!!
Hope this helps!

The definition of "bricked" is having a really expensive
... brick. It means your phone doesn't turn on no matter what you do to it (short of a JIG and that's not guaranteed) the "USB device not recognized thing" is a problem w many windows devices my vista computer does it all the time and I just switch ports.

Hey, was there every a solution found for this?
I'm having basically the same problem...using the cable that came with my phone, and have installed Kies (fresh). I have tried toggling multiple settings. I tried uninstalling kies and reinstalling. I tried using pdanet for the driver. I have tried a few different roms, as well: Darkside 2.4, 2.5.1, and gingersnap 1.21. All have had the same result.
When I plug the phone in, it beeps (charging) but no notification for usb settings (disk drive, sync, etc). On my computer, it pops up "USB Device Not Recognized" and says the device has malfunctioned, etc, same as OP.
In Device Manager, it shows under USB as "Unknown Device".
I have tried this with two Windows 7 laptops, and a Windows Server 2008 R2 desktop. Also tried with a different cable. This cable was able to transfer data from an external hard drive today, so I doubt anything is wrong with it.
Any help is greatly appreciated!

I tried without the drivers, and went to wireless and network > USB utilities. The only option in there, however, is "Connect storage to PC". If I try that, then plug it in, the phone acts like I hit the back/undo button. It doesn't show that anything is connected, nor does it give any other options. At this point on the computer, I get the "USB device not recognized" error.
This happened before installing Kies/Drivers, and still happens after installing drivers and kies.
try another usb cable
i had the exact same error, and it ended up being a good USB cable that went south
I will try a different cable when I get home - Have a month old cable for a mytouch 4g that I know works.
Okay, I tried it with the other cable, on a desktop in the rear port. same thing...Phone start to charge, and I get the error that the device malfunctioned, yada yada.
Any other ideas? Should I try to connect in Download mode?
Alrighty, so in the end, I ended up completely unroting, using terminal emulator to remove superuser.apk, busybox, and su and putting right back to read only. Then in CWM, flashed a stock 2.3.5 ROM (Zedomax). However, I now have the 2.3.5 ROM and the 2.3.6 KL1 Kernel...
I'm planning to return to Tmobile/Samsung - will the kernel and rom versions not matching be a huge red flag??
Any help is appreciated. I have tried to flash the 2.3.5 kernel, but I always get an error that it's not signed/verified.
Ideas?
I was hoping to grab the 2.3.6 OTA update, but it says there is no firmware update. Is there an update file I can put on the SD card and update using the stock recovery?
UPDATE:
I called T-Mobile Customer Service today, and went through the "troubleshooting" with them again. They ended up sending me a new one, overnight. They didn't ask anything about doing anything custom with it like rooting or other modifications.
I'm not sure if it made a difference, but I'm within 90 days, and also have the "best" insurance/warranty coverage through T-Mobile, and whoever their insurance provider is that I signed up for when I bought the phone.
Final charge is for $5, which I was told is some kind of fee from Samsung, but will appear on my bill.
Anyway, not too bad. Can't wait to get rid of touchwiz again when I get the new phone!

I'm running 4.1.1 and every time I plug my device in (With stock USB) I get "USB device not recognized"
I've tried another USB. I've downloaded Kies (Will only connect wifi), I've tried reinstalling drivers, I've tried using another computer as well. I've also enabled/disabled USB debugging,
The USB connection notification only appears sometimes, and even when it does my computer still won't recognize my S3. After I reinstall the drivers my phone does say "Connected as a Media device", but then the notification goes away..
FYI, I'm trying to root, that's why I need a direct connection with my computer so badly.
Does your computer has samsung kies?
You say drivers. Idk what u mean but all we need is samsung kies.

I tried your method a few days ago, and it didn't work. I tried your method again.. it doesn't work.
I had this issue. All I did was get some good ol canned air and blew the dust out of my micro usb port. After that it connects just fine. Was about to do a warranty exchange before I did this.

Tried that as well. Neither computer works. Blew into the phone as well ...
Its your rom on the phone that's causing this. If you want to rule it out, why don't you just do a nandroid backup and install stock rom or perhaps the same rom clean from start. I had this issue before and it was fixed with reflashing clean rom.

Read his post, he is attempting to root. How does one backup their rom and restore with a stock recovery.

I'm not rooted ...
I should probably mention the phone charges will of the USB cables but none of them work with the PC. I can't tell if it's a software issue or internal..
I think it's a computer issue, what was the other computer software you tried on?

Tried it with W7 & Mac, neither recognize the device. Android file transfer just tells me "no device found", and the Kies on mac doesn't work either.
I still won't update my computer from XP cause all I read are device errors with upgraded versions of windows... see if you can get your hands on XP and try. Just as insurance, you have gone through device manager and removed all drivers for the phone and then pushed the proper ones from Samsung, correct?

watch the screen closely when you connect the phone to the pc. does it even recognize thst some usb device was plugged in?
After a few moments, (with the phone still connected) click start,right click on my computer, select manage and select device manager.
are there any yellow question marks on the right side under the computer?
Open the modems (click the + sign) is there any SAMSUNG USB Modem? (should have no yellow question mark)
Open Universal Serial Bus controllers, do you see the samsung Mobile USB Composite Device?
There should be NO yellow question marks or exclamation marks anywhere on the right panel.
If there are, there is a problem with your computer settings/drivers or services.
If you followed my "cannot fail" steps EXACTLY in the order I had it, and did not skip anything, you should be without any problems with the modem connectivity. That includes the uninstallation of any samsung drivers previously installed.
If you do not even see the samsung modem, the cables or the phone may be your problem.
Post your results and I'll help you to get it working. Also mention what your compurter's OS is.

My bad, speed reading is not always good... thanks for pointing that out.
Anyway, did the OP ever get this resolved? Bobolinko's steps are thorough and if that didn't fix it, why don't you just try to go into download mode and ODIN a stock ROM with root injected into it already? It's another option...
Did you try buying a fresh new cable to connect the phone to the computer? I only have those issues with corrupted USB cable and a messy laptop...
Also when that notification appears for me I go to my phone USB section and tells it to mount as storage...and if its on storage I switch media than back to storage...always work for me.

As soon as I plug my S3 in, my computer recognizes a USB is active. In Device Manager, I do not have Samsung USB, all I have is "Unknown Device". I'm not sure what you mean by yellow exclamation point in the bottom right, but there's nothing in my notifications. However, I do get 2 yellow exclamations in device manager. One in Universal Series Bus, and one in other devices
Hi there.
Check this
On calls hit *#7284#
Check if pda is enabled then click on qualcomm settings and see if mtb+adb are enabled.
If not then just enable those.
Hope this is your problem.
Good luck.

I've tried this as well. I get this error:
"Connection problem or invalid MMI code"
The problem is with your computer, and not the phone. You CANNOT get it connected with a problem in the USB settings.
click on the yellow exclamation items and DELETE or UNINSTALL them. then reboot the machine and it should reinstall automatically. If your DRIVERS that are already in the machine are bad, you have to get them updated or replaced. uninstall KIES from the computer, reboot, and reinstall it. go to samsung's site and download and install the driver for your comuter.
The one for the xp is: SAMSUNG_USB_Driver_for_Mobile_Phones_1.4.8.0.exe
install it to your computer and be SURE there is no error while it installs.
then check again your device manager list for any yellow problem areas
connect the phone and wait a while, then, disconnect and wait about a minute
then again, connect the phone, and wait at least one minute. open the device manager page and see if there are any yellow area problems again.
are you positive you have the latest window updates?
you can sometimes right click on an item and do the driver update and fix a problem.
You clear all the COMPUTER END PROBLEMS you have and the phone will connect. That, my friend, you can take to the bank.
Good Luck!
Aloha,
