[ADB] Device cannot be started (Code 10)

For some odd reason, I lost adb functionality (i.e. any adb command issued receives "error: device not found"). I looked in Device Manager and noticed that MyHTC was gone! I looked at my phone and USB debugging was enabled and in charge only. I could put it in USB Drive mode and the PC would recognize it as a USB Mass Storage Device so that I could exchange and view files but no adb.
I searched and searched on this issue for hours and installed over a half a dozen "androidusb.inf" driver files several times over. Every install generated the Code 10 error where Device Manager was lacking some information from the driver file and could not start the device. I reinstalled HTC Sync and gave that a try...nothing. Downloaded USBDeview and uninstalled all HTC drivers including the HTC Android USB Device and tried again to no avail. WTF?! What else am I supposed to do?
Well, in a "what the hell, let's give it a try" kind of moment, I decided to toggle the USB debugging off and then back on (and yes, it was checked and on the whole time). WORKS!!! WHAT THE CRAP?!! MyHTC is back in Device Manager and everything is back to normal. I'm glad but irritated!
I share this story in hopes that if someone else stumbles on this problem, they will not have to go through the same headache as I did. Just thought this was odd considering how many times I have plugged and unplugged and never had any problems with adb.
Toggle USB Debugging....so simple. *rolleyes*

Same Issue
I've got the same issue on my EVO 4G. Just installed the latest CM7 and now it tell me device not recognized. If I manually install the drivers it gives me the same code 10. I can't bring up the phone as a storage device and toggling the debugging is not working. Any ideas?

You installed the hboot drivers correctly?
Boot into recovery, with usb debugging enabled, connect to pc, it should install the drivers.

Still the same
Even when I reboot into recovery it still gives me "USB Device not recognized." I previously had MikFroyo on my phone with no problems. I'm at a loss.

You most likely have a bad cable, do you have another one you can try?

Possibility
Not at the moment but that may explain it. Still seems weird for it to just go out right as I change to CM7, but still a possibility. I am going to run and grab my other cable. Thanks for the advice.

No Luck
The new USB cable didn't fix the problem. Also, in device manager, even with the driver installed its labeled as "unknown device."
If I boot into hboot the computer recognizes it.
**update: After rebooting from the hboot, my phone is recognized by the computer however, a disk drive is not coming up in "my computer." I have USB storage turned on but Im not getting anything.**
Any help would be much appreciated!

Sad Day
Apparently the Micro USB port on the bottom of my phone is going bad... I talked with some other people who've had the same problem. HTC knows that the ports aren't very sturdy as well. Well... sad day for me.
Also if you're getting the notice from windows saying that you your device will run faster in a 2.0 usb port and you know the port is 2.0 ... chances are your port is going bad as well.
*****UPDATE*****
Flashed to MikFroyo and none of the above stated problems. I would venture that it was CM7 but apparently everyone else is able to use it so who knows.

[Q] Completely different connection issue (I think)

Let me start by saying I have read dozens of threads on connection issues from the original galaxy to the s2 and none of them have worked. Here is my problem. When I plug in my phone I get a MTP connected dialogue box but kies will not recognize my phone and odin won't recognize my phone in download mode. My computer's device manager doesn't even show drivers installed or any yellow triangles at all. As a matter of a fact, my computer does NOTHING when I plug in my phone. No installing drivers dialogue box or anything. I have tried manually mounting usb storage mode to no avail. I can not transfer files, root my phone or do anything. I'm running stock EK02. Also, with usb debugging box checked my phone just charges with no pc connection at all. with usb debugging unchecked it will show the mtp connected but my computer doesn't show anything
Here is what I've tried:
Installing and reinstalling kies about a dozen times.
uninstalling and reinstalling samsund drivers
rebooting my phone
tried different computers
I EVEN BOUGHT A NEW COMPUTER (brand new nothing installed)
Then I bought a new usb cord
restarted my computer several times
checked then unchecked usb debugging just in case
Please Help, I'm completely stumped......
I can get on multiple chats for anyone interested (gtalk, facebook, irc, whatever) or take responses here. thank you in advance.
--------------------------
UPDATE: so it was the USB cord the while time. Apparently you should really only use the USB cord that came with the phone, which I lost and had to borrow from someone else.

[Q] Connect as hard drive / Charge only

I have had this phone for only two days now. My previous phone was an EVO. I got my Epic 4G Touch via a trade and there is one thing that I cant figure out... and feel quite silly asking the question.
When I plug the phone into my PC via USB, I do not get an option or prompt to choose whether to connect as a hard drive / charge only / or tether my internet connection like I did on my EVO. It seems that it only allows me to connect in charge only mode. I have been unable to find an option to choose to connect as a hard drive in the settings menu.
Any help with this solution will be greatly appreciated.
Thanks
Robert

Ok, enabling the USB debugging and then unplugging and plugging in the USB fired up those settings, but it did not find drivers for:
CDC Serial or SAMSUNG_Android... I am going to search the forum for that answer.

Settings>Wireless and Networks>USB Utilities. That's how you get to USB mode. But yes debugging mode also works. But once you plug your phone in the mtp mode should connect. You can also access media on PC that way and ur sd card is still accessible thru phone, unless you're actively syncing something then you get the sync screen.

for my phone as soon as i plug it in i get a notification at the top and i pull down the status bar and i can enable usb mass storage from their

Thanks for the reply folks. I had me EVO so long that I forgot about enabling debugging mode. I did that and I finally got the drop down menu to enable me to use the phone as a hard drive.
My issue now is that I cannot seem to get two drivers to install correctly. I read through many posts, both here and ones I found via google, that suggested that I install Kais from Samsung's website to fix the driver issue. I did that, and applied all of the updates to the program that were available, and I am still getting the error saying that those drivers did not install correctly. I can browse the SD card now that Kais Air is installed, but I am still having the driver issue in device manager.
I am not sure where these drivers can be obtained...

Other than Kies, your pc should install drivers upon connecting phone. I've had this happen before. I uninstalled the drivers I found via google, restarted my pc, reconnected my device and it immediately began downloading proper drivers. I was good to go from then on.
You may wanna try, once device is connected to pc to
-go to start menu
-computer, and see if your device is there

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

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.
