this just happened to me today, i tried to put a file on my sd and my phone would not give me the option to mount. Its like it wasent even recognizing that it was plugged in.

however, I am able to use the same usb cord for my wall charger.

is there a problem with my phone, or my computer. Im using xp (yes, still) and havent had any issues till now.
 
1) Reboot CPU

2) Reboot Phone

3) Verify that you can see the contents of your SD Card on your phone (via Astro or other file manager).

______________

4) If the first two things don't work, disconnect cable from phone, power down, and remove your memory card from your phone and insert into a card reader (hopefully you have this capability). You are going to want to to copy all files over to your pc (basically backup your entire memory card).

5) Re-insert card into phone and format your sd card (this will erase all data)
To do this, go to Settings > SD card & phone storage > then select "Unmount SD card" then select "Format SD card".

Once you have done this, make sure SD card is mounted (Unmount SD card" should be selectable).

The use of Debugging tools only occurs with Windows systems that don't have the driver correctly installed / have a corrupted driver install for the Motorola A855 USB drives.

So, the inherent problem is still with the drivers on the Windows system.

I suggest cleaning out the drivers completely. reboot. Connect your DROID and let Windows Installer find an install the drivers from WU.

Actually it does, at least for me. After I rooted i wasn't able to mount my phone to my PC at all. After troubleshooting the problem I found that that the only way to mount my SD card was to check the USB Debugging box.

I recant my previous statement!

I have never had that issue with my droid (and USB Debugging is ALWAYS on). I just finally convinced my wife to let me root and improve her setup and I ran across this issue. I tried everything and then remembered this thread. I turned off debugging and the USB mounted. I don't know why my phone was never affected by this and my wife's was...just one of the many things I can't understand :D

I suddenly started having this problem, out of the blue. I feel it's some issue with Win7 64bit. I had both USB Debugging and Mounting working fine since I had the Droid, and then suddenly it stopped. I cannot mount the Droid if USB Debugging is enabled...that is on my Win7 machine. On my Vista 64bit box and Vista 32bit laptop, I can mount and have it enabled just fine, as I could before on the Win7 box.

The only thing different on the Win7 64bit box is that I used it to mount my wife's Devour as well, so I'm suspecting some driver incompatibilities with these two devices, despite they are both Moto devices.

I uninstalled the drivers, rebooted both the PC and phone, removed the card and put in an SD adapter, and can read it fine. Nothing works, except disabling USB debugging.

This is a pain, because I do QA for a developer, so have to use the USB debugging, in addition to wanting to manage my SD card without having to remove it.

I just tried this - disabled USB debugging and my phone still connects - and it is rooted, running UltimateDROID 6.3 with Chevy's No1 1.2 GHz kernel....

John, my phone is running the same setup as your (except the kernel...my phone doesn't like 1.2 or 1.25 Chevy kernels and I don't know why) but it connects all the time with USB debugging enabled or disabled. I have never had a problem.

My wife's phone mounted successfully earlier today with debugging enabled but then failed to mount later in the day when I tried it again. I turned off debugging and it mounted sucessfully.

I just plugged it in again with USB debugging enabled and it failed to mount. The phone saw the USB connection but the computer did not. She is running the EXACT same setup as me so I don't know what the difference is. I'm not concerned about it...just interesting and I didn't see how turning off debugging would allow a phone to mount...I do now.

I having a problem with with this as well.

My Droid will not mount unless USB debugging mode is ON. It also seems that it will not even charge with debugging off. (The icon shows as charging, but the battery still dies down)

I am experiencing the same problem on both an XP machine and a Win7 64 bit.
It only started happening recently. May be related to DroidMod, as I recently updated to that from the Sholes version.

Wow i might have to change my sig because i did a search and found this thread. Mine will only mount with de-bug on running droidmod 1.0 and i dont remember if i had this problem with sholesmod... Anyway im glad i got it to charge while using wifi tether.

Oh and in the mean time in a pinch i transfer things to Google docs on my pc then DL to the phone. Not much good going from phone to pc.

Thanks for having the same usb problem i did though!!

Same, my phone wouldn't charge unless I had debugging on... What is really strange is, I haven't had this problem with WIndows 7. Only XP and Vista...A driver issue perhaps?
