I haven't found this problem discussed, so here goes.
My wife & I have identical Droid A855s except mine is rooted (running CM7) and her's is stock (2.2.2, FRG83G). Last week she asked me to put CM7 on her Droid also but ... I can't get the USB/PC connection on her Droid to work.
Here's the deal ... I plug my Droid into my PC/USB cable, the USB connected screen comes up (asking if I want to turn on USB storage).
I unplug my Droid and plug in her Droid. It indicates that it is charging but ... no USB connected screen, no notification icon, nothing. It's like her Droid is missing it's internal USB driver or something.
Yes, Development Debugging is enabled. Any thoughts?
When I connect a usb to my droid, in the status bar appears that icon with an USB image. Tap on it and select something like "Acces Memory Stick".
Disable the development debugging, I have a milestone and when I first install a custom ROM (CM6) I was having the same problem, until I disabled the USB debugging, I don't know why it happened but it got fixed by itself(?) with the time...
same here
i use cm7 posted by kabaldan on my milestone 1,
i lost my baseband and bluetooth address the same time...
also my camera is not functioning right... any solution?

I needed to transfer some files from my N1 to my Pc, so I connected it to my PC using the cable. I was expecting the black mounting screen prompting me to mount the SD card, but nothing happened. I restarted my device twice, but the case is still the same. What could have been wrong? I have not installed any app within this time, not removed any. I have used it in just ordinary daily manner, messaging and calling and nothing else. My N1 runs on Froyo, OTA. No jailbreak.
Please help. Thank you
u need to assign a drive letter to your SD card
Noob answer: is it on the status pulldown bar?
Do you have USB Debugging enabled?
Does the phone recognise that it's been plugged in (ie start charging)?
Similar problem
I am having a similar problem with my N1 running CM6 stable. When I turn off USB debugging and plug the phone into my Win7 laptop, I get the USB connected screen, but when I turn on USB storage the SD drive doesn't mount i.e. I cannot see/access the drive in Windows 7. The N1 status bar says USB storage is on.
Under Device Manager, the N1 shows up as Android Phone-->Android ADB Interface with driver version 2.0.10.2 dated 11/08/2009.
Any help would be much appreciated.

No, THIS is exactly the problem, the phone dies not recognise that it has been connected to a computer. It does start charging, but no sign of SD memory mount/unmount. Nothing. Just simply charging.

No, USB debugging is not enabled. I double checked it.
I guess that Windows also doesn't recognize the phone as anything (Device Manager doesn't show anything new plugged in)?
In that case, enable USB Debugging, and see if the phone is recognized by Windows.
If it is - the problem is somewhere in SW.
If it isn't - then it might be a faulty USB cable or connector (from any side - phone or PC).
same thing happens to me from time to time. restart your computer and that should fix your problem.

I went into menu -> settings -> connectivity, and set the USB connection to "Always Ask" when connecting to a computer so that it would ask me if I want to use Charging/Mass Storage/Media Sync/etc. Even with that box checked, no matter what I do, when I connect the phone to my computer, it does NOT ask me what USB connection mode to use. Can anyone else confirm whether or not they experience this problem?
Thanks!
SOLVED - driver conflict with my Samsung Epic. Connecting one then the other wreaks all sorts of havoc.
call Verizon or LG for that support..OR try your control panel windows settings..devices

Is the little USB symbol showing up in the notification bar?
If not...try a different USB port on the computer.
Sounds dumb, i know...but it worked for me today when I had the same problem. And I think I recall it working on my old Incredible.
SOLVED
SOLVED - driver conflict with my Samsung Epic. Connecting one then the other wreaks all sorts of havoc, between mass storage mode and whatnot. When I switch the LG from charge to mass storage and back on the fly, it's doing something to the samsung drivers. When i reconnected my samsung, then the LG again, things went cuckoo for cocoa puffs until I rebooted.
I can't post a new topic as I have less then ten posts but I have an issue with my connectivity as well. When unplugged the phone still shows the USB icon in the top left corner like it is plugged in. However when plugged in the phone will charge but when connected to a computer mass storage mode will not work or show up. I have tried it in windows xp/ osx on my MacBook. Windows 7 on my desktop and nothing. The drivers are good as it was working before. I have done a wipe/data, restored back to cubed 1.1 mod and it is still doing it. It doesn't bug me that bad as I use andftp to move my apostle back and forth from my NAS to sdcard. But I would like it fixed as trying to put music or ISO's for my psx emulator can take a minute over the wifi. Any help would be appreciated.

Why am i getting a Factory data cable connected and i cannot switch between usb modes?
I have a rooted bionic with blurr3d rom installed. i just got a new laptop, installed the moto driver, tried connecting my phone but laptop cannnot read my phone. I noticed that i dont have the usb conection option anymore(or dont know where to find it)
Any help would be nice...
Can you give some more info, what kernel are you on right now?
Does the phone make any sound or indication that it is connected when you plug it in to the laptop?
If there is a USB connection, there should be an icon on the notification bar and there should be a notification for "USB connection" when you open your notifications. If you select that, it should bring up the usual USB connection menu.
I've heard of some people having issues with connections on USB ports that get low power. On desktops, people generally recommend using the ports on the back because they receive more power, apparently. I've also heard of similar issues on a laptop, though you don't have the convenient option of using another set of USB connections. Most of that has been information I've seen for stuff like flashing something on the device, so I'm not sure if that would be an issue for the basic USB connection.
Try a different USB cable.
I am having issues with the activation of USB Mass Storage mode on CM7 v7.10. When I first connected my nook (just got it yesterday), I was able to enable mass storage mode as per normal. However, after this it's just stopped working!
There's nothing wrong with the cable afaics because the empty drives come up on the PC (Win7) no problem, it's just that the nook doesn't detect that the USB is plugged in and so never gives me the option to enable Mass Storage mode. I have had success once running ROM Manager's 'Fix Permissions' function, but since then it's not made any differences. The issue remains on multiple PCs with multiple cables.
Anyone got any fixes for this issue?
+ can you wiggle the micro-usb end a bit to see if anything better?
+ do you have the "usb debugging" check?
+ do you see the usb icon displayed on the NC notification bar?
- No wiggling makes any difference
- Tried with USB debugging on and off - no difference
- No USB icon (but empty drives still show up on my PC) so there is some kind of connection going on.
If the empty drives do show up on the PC, it definitely some sorts of connection made, it's a good sign.
Now back on your NC, go into Storage, try to Unmount then Remount the uSD and see if it gets any going.
Note: leave the Debugging USB Mode on.
Might also be worth considering moving from 7.1 to the MiRaGe 7.2 build. I'm not saying there is a specific fix but using the later ROM may help and I think most people find it more stable, faster and problem free.
Yeah, I actually updated to KANG 7.2 this avo and the USB Mass Storage option is back!
Thanks everyone for your suggestions!
I currently having KANG Mirage 7.2 with Tablet Tweak but it did not work. I bought an OTG cable from ebay so I assumed it's bc the OTG cable. The Drive works fine on my laptop but nothing appears on the Nook.
Maybe a re-flash with the same ROM might do the trick?
I'll try to reflash sometime soon!
Will post
uSB mass storage
I had the same issue. Have the USB connected and while connected reboot your device once it has rebooted you'll be able to access the USB files on your device. You'll be able to see the USB signal at the bottom, which you can activate. You'll have to do this most likely everytime you want to access USB storage

I'm on MIRAGE 7.2 running off EMMC. SD card is in the Nook.
I shut nook off, plugged in the cable to my pc and started the nook.
5 drives show up but I cannot access any of them. The USB icon is in the tray on the Nook and it says "USB connected". Just above that it says, "USB debugging connected"
Anybody have any success?
After doing some reading I've decided to use ES-FILE Explorer wirelessly. Its very easy to use. You need to SHARE folders on your PC in order for it to access the files.
Playing around with the USB option some more, I didn't realize that you could TOUCH the message in the notification bar. When you do, it launches a program and from there, you turn the USB connection on or off.
Geeeeeeez........ya learn something new every day.
The phone charges fine when plugged into the usb port, but I get usb device not recognized errors. It doesn't even popup to install any drivers.
I've tried installing the motorola drivers manually, but that didn't work either. I'm using the cable that came with my lg revolution as verizon said that would work just fine for the bionic. It does, but just for charging not managing the sdcard, etc.
When you plug it in, pull your status bar down, then select your USB mode. Make sure you don't have it set on charge only.

There is no usb notification on the pull down bar for some reason. Not even toggles for wifi, bluetooth, etc on the pull down bar.
Verizon is sending a bionic cable =/.
Check to make sure that your usb ports are working, my laptop shorted out all its usb ports at once while my bionic was plugged in. Also make sure that the cord is plugged in correctly to your phone and computer
If its charging but doesnt show anything in the pulldown, either your USB ports arent running correctly or the cord isn't supported for usb transfers.
I am having the same issue with my wife's phone. We both have Bionics and I have tried both cables on both PCs, mine works flawlessly on all, but her's will not detect a USB connection except to charge. Plugging the USB cable in shows battery charging but will not prompt for USB mode.
When Windows detects the device the driver install fails saying "Device unplugged"
Having usb debugging checked under apps can cause similar problems also.
I have to select Turn on usb storage. then unplug the cable and plug it in again. selecting turn on storage again usually does the trick.
This is on AOKP SELFKANG roms. YMMV
Have tried unticking USB Debugging, did not resolve issue.
Unable to toggle USB Storage as the phone does not detect and prompt when plugged in. Has worked previously, just stopped.
Just got the cable Verizon sent me, it's not even working either. I get no prompt to enable usb, I've tried usb debugging on and off, tried every port on my computer, this cable is the only thing that will not work in any port, the ports are good since I have other things in the same ones I've tried.
Now motorola is sending me a motorola cable after making me do a factory reset to test the one Verizon sent me -_-. God, I'm getting tired of reinstalling/setting up everything. There's no way to backup, etc without being rooted is there?
Let us know if the Motorola cable fixes it.
unfortunately, no you can't back up your phone w/o it being rooted.
that sucks about the cable, I would be all over VZW sending you a new phone if the cable from Moto doesn't work. It should be covered under the hardware warranty and should only cost you shipping.
have you tried either cable on a different computer altogether?
I had this very same problem on my samsung Captivate and then again on a brand new LG Thrill. they had worked fine connecting to W7 ultimate. then one day nothing. got the USB failed error. no USB connect option on the top bar. got the LG replaced last week. hooks up fine just like the last one.
Moto cable, 1st plugin and it works fine -_-.
at least it is working now, makes no sense why some of these devices can use literally any micro usb cable you can find (mine is this case) and others you HAVE to use the Moto cable or nothing will work.
That makes so little sense. I have two Motorola cables, the ones that came with the phone, and neither of them are working with my wife's phone.
from my Experience, Only the stock Bionic Cable works right. Others dont charge as fast and wont let me mount to pc. Not sure why. Guessing maybe the Bionic cable is set to higher frequencies since its a Dual core phone?
Well, as an old RF engineer I will make a guess. I recall folks saying the inside two pins carry the data. The data rate is certainly high enough to cause problems if the cable is made wrong. I will look in my old test equipment pile and see if I have a way of checking the cables I have.
I do not have a Motorola cable to test, but I do have cables from VZ that do not work. I may be able to check the data waveform in the time domain and see what it looks like (amplitude, slope, and shape). A TDR would be nice, anybody have one?
Uninstalling usb devices might help
I had the same issue with my bionic. Before the bionic I had the OG Droid, the X, and 2 X2's. So I had a plethora of seemingly identical OEM moto cables. I still couldn't say which one came with the bionic. That said, none of the cables worked consistently. I had the best luck uninstalling everything USB in device manager on my pc.
Go to start, right click on "computer", and then click on manage.
In the window that opens, on the left side under system tools click on device manager.
Then in the right side of the window navigate to USB controllers and expand.
Uninstall everything that is listed, but don't delete drivers if prompted.
After everything has been deleted, right click on computer at the top of the window and scan for changes.
This will reinstall everything and clear out any errors on the bus.
From there I have had mixed results depending on whether I had the phone connected when I rescaned for new devices. Sometimes it would work if I had the bionic connected and sometimes it wouldn't work unless I waited until all of the USB devices reinstalled and then connected the bionic.
Another thing that seemed to help was to unmount the sd card on the bionic settings>storage, and then remount.
Again, nothing worked consistently except replacing my bionic with a rezound.
OK, I have finally been able to get my Bionic to work. And the truth is, there was nothing wrong with the Bionic!
I asked VZ to send me a data cable, after two tries I still didn't have one. So I called Motorola and they sent me a data cable, the cable number is: SKN6378A.
Worked like a charm.
I think I know why this is happening. From my conversation with VZ customer support I can tell the cable list is not descriptive enough to help them make the correct selection.
Yes the data cable that came with the LG Revolution would not work on the bionic, also the new cable has a larger diameter.
