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.

Did this and that got my computer to acknowledge I had connected my phone but not it says unrecognized, so I'm going to uninstall kies and then reinstall again and see if that helps

The way connecting USB storages to PC on Stock FC22

The issue in here is resolved. So, if you wonder how to connect phone's USB storages into PC, please check the update 3 section in below.
If you are a user of USB utilities, stay away from FC22.
I'm not sure if this is an intended directional change from Samsung or if this function is missed by mistakes, but on FC22, I do not see the Settings > More... > USB utilities. I saw it until FC18 and it's not in FC22.
So, if you use your internal or external sdcard thru this tool, this would be a reason why you stay away from this rom until it's fixed -> Not valid any more
Now I moved back to FC18 from FC22 because I'm a kind of heavy user of this tool because it's really faster than any other method whenever I transfer the data between sdcards and my pc.
Maybe my eyes are wrong but I tried to find this function from everywhere in the settings but couldn't find. If someone find this function, please direct me to the right place.
Tweaked Calk's FC18 Rom is working fine (almost no defects) except the way entering the ##debug# mode. I'm still don't know how I can get the 'lock code' on ICS version (not MSL code).
(attached screenshots: first - from fc22, second - from fc18)
Now I'm sitting back and waiting for next build....
[Update1]
I've applied Fc22 Kernel and modem upon Calk's Tweaked FC18. - USB Utilities is still there.
Next update would be - factory reset and clean install FC22. Will follow up shortly
[Update 2]
Because I factory-reset my phone, it's taking longer than before to update. I'll post the screen shot in few minutes but Samsung replaced the USB utilities to Kies via Wi-Fi.
I've seen that Samsung in Korea, they are upgrading customer's phone thru visiting customer center or via 'Kies via Wi-Fi'. Are they following the same steps in here?
Because I installed Stock FC22, I ran Calk's Bare Rom Converter and it includes the scripts removing Kies APKs. I think that's the reason why it's not showing Kies via Wi-Fi (default in Stock FC22 instead of USB Utilities).
[Update 3]
Thanks to Dchibro, mdsevol and kali323
I don't need to test it any more. On FC22, the way phone communicate with PC has been changed a little. Usb utilities on the settings is removed and replaced with Kies via Wi-Fi.
So, to make the PC recognize the phone's usb storages, go to Settings > {} Developer options > turn off USB debugging > connect your USB cable
Another way connecting USB storages to PC (big thanks to elliwigy)
I pull status bar down and click the USB notification then turn USB mode on and it connects to PC for file transfer..
Once USB cable is connected, PC will recognize your internal and external sdcard.
I think this way is better than before and it would be one of the reason why I'm moving forward.

I'm on codename and flashed the fc22 kernel and modem.. no issues but I always plug it into PC to transfer stuff.. it loads right up..

Ok. Let me try to load fc22 kernel and modem on my current fc18 rom and check if it's still there. If it's there, then it's not the kernel or modem issue. I need to factory reset and reinstall the fc22 rom (I've already did that) and check again.
Anyone else?

All is well here

I'm updating my interim results at first post.

Does enabling USB debugging turn off MTP and make USB mass the default like it does on the GB ROM? I'm guessing no but I thought I'd ask.

The option isnt there on mine either, I am running stock FC22 with modem and kernal although when I connect my phone via usb it still gives me the option to connect mass usb storage. Is that what you are talking about?

I'm not sure I see what the problem is then, other than Samsung already handling MTP vs Mass USB horribly on their ROM.

Problem solved. It's working like a charm and better than using USB Utilities.
I'll update my thread with this information.
Thank you guys!

Actually, by default, the way USB storage works in FC22 hasn't changed, it still defaults to MTP mode and is as annoying as ever, plus they removed the USB Utilities option in menu->settings->more so you can't manually enable it anymore.
The reason you got the impression it changed is because Calk modified a property in /default.prop (in the kernel he bundles with FC22) which controls how the USB storage is configured, so if you used his modified kernel to install FC22, the USB mode will be changed from MTP mode to Mass Storage mode. Once you have USB Mass Storage mode configured, it will be stored persistently in your Android User Data, so should you change kernels in the future, to one which doesn't have the change Calk made, USB Mass Storage mode will remain. The only ways it would get reset if if you wiped your Android User Data AND switched to a kernel which didn't have USB Mass Storage mode enabled in /default.prop
I have added a solution to the ICS USB Mass Storage annoyance to the Auto Root package. This will allow you to manually choose USB Mass Storage Mode (ie GB USB Storage behavior) for theoretically any ICS release, though I only tested it for FC22. Use Option E (Extra Options) followed by "Enable ICS USB Mass Storage Mode". This option will be stored persistently in your Android User Data, so it only needs to be done once (or whenever you reset your Android User Data)
Full writeup is here (and also in the FAQ of the Auto Root sticky)
What happened to USB Storage in ICS, how do I get the old GB behavior back?

The problem is that we are seeing lots of build every daily basis but there's no additional information about the new build. Only the way we would know the changes is through our own test. In here, we are being used as kind of testers even we are donating our own time for free. If someone who provide the source to our forum, if they have any kind of basic ettiquette, please provide the basic information regarding the change also. That will save lots of our time and prevent us from misleading and posting wrong information. But that would be one of their intention though.
Personally I want to add my thanks to sfhub for his kind explanation about what's going on and what's happening.

[Q] USB not recognised

Hi all,
I've read a lot of forums on what seems to be a pretty common issue, however, with each attempt at a fix the answer is still elusive.
the problem i'm experiencing is that when I connect my (unrooted) Galaxy S2 to my pc (running windows 7) the USB device is not recognised. The phone says that it is connected (USB Connect MTP-Connected), however, when I try to access my phone via Kies or explorer it is not there. I also get an error message saying that the 'device is not recognised'.
I've taken the following actions:
- Reinstalled a fresh version of Kies
- Reinstalled samsung drivers (once prompted by Kies)
- Tried at least 3 USB cables including the original Samsung cable
- As per one of the blogs i read, i switched to USB debugging on and then off as there was no effect
- I've tried turning on bluetooth, then connecting the USB device (also a 'fix' i've seen on another forum)
- I've restarted my phone a number of times
- Connected via different USB ports
- Restarted my PC
Could anyone please help me.
Thanks,
Rob

Uninstall all drivers, and Kies.
Restart the computer.
No go to device Manager under Human Interface Device/Universal Serial Bus controllers and see if there is that little yellow triangle there. If so click and uninstall any device with the aforementioned icon.
Now reset again.
Go to the Samsung website and download the drivers for the phone. Restart the computer yet again. Almost done.
Now attach your phone and it should be identified.
Go ahead and install Samsung Kies and you should be ok. I hope all this works.

I had a very similar issue with my last SII. One day it just simply would not be recognized by many computers using various USB cords including the OEM one. Windows always said something along the lines of " USB device not recognized, a device connected to this computer has malfunctioned." The computer would pick it up bit was listed as an unknown device in the device manager. Turns out it was a hardware failure so I had so get a warranty replacement

Not very helpful answers... you may have sorted this out already but...
One solution found on other threads that worked for me was this:
uninstall Kies
key in the dialer *#7284#
it has 4 option there..
UART (MODEM/PDA)
USB (MODEM/PDA)
Only change the USB setting.
Select PDA, if it already selected, select MODEM, don't hit "back", try reconnect, wait for windows to respond.
Unplug, then select PDA, try reconnect.

Try changing your usb cable. If that still doesnt help, try it on another pc. If still not, then send it to samsung for repair.

[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.

Cant restore phone. MobileGO thinks USB debugging is disabled.

I created a thread on Mobile GO's forums but I probably have a better chance of getting help here.
I need to restore my phone with a backup I took with Wondershare MobileGO application on PC. However I keep getting prompted with the screen telling me to turn on USB debugging. I tried restarting my phone & PC, different USB splots, and toggling USB debugging on and off.
Any ideas?

I had this same problem: couldn't restore because MobileGo kept insisting USB debugging wasn't turned on. However, I found a fix. Instead of using the "Data Recovery" button on the home screen, I went to the "Super Toolkit" tab and selected the "Restore" button under "Essentials" and it worked like a charm!
