USB device not recognized when plugged into computer

Hey there,
Honestly I dont have access to my droid as of yet (in the mail) so I cant be totally sure but it sounds like you need to load the motorola USB drivers that can be found here. That's only the windows versions though. Hope that helps you, pretty sure it will. Anyway, GL .

 

You are mounting the phone inside of the droid right?

 

Check the notifications on your droid after you've plugged it in. You have to explicitly use the droid as a usb storage device.

 

Glad you got it figured out. I had a similar problem on previous phones and had to get it exchanged at the verizon store shortly after puchase. Sometimes these phones are just DOA for certain features, which makes me wonder if or to what extent they are tested.

 

Good support from Verizon

It certainly sounds like Verizon is quick to swap out phones when things go wrong. I like that! No hassle, just pretty good service.

 

My issue is a bit different.
When I plug in via USB into my windows 7 laptop it is registered and appeared as a separate drive, but when I try to open this drive in explorer – it is not accessible. The card seems fine, I was able to move files via Bluetooth with no problem.

Any suggestions?

 

I had the exact same problem with the messages "USB device not recognized" and "USB device has malfunctioned" appearing even when the droid was just charging with a PC (not file syncing). Sometimes it would go a whole day without an issue, other times it would occur immediately when connected, although file syncing was always an issue.

The droid would also sporadically reset itself. It was intermittent however, sometimes I was able to mount the drive, but the drive would dismount itself after a few seconds or minutes. This occurred on both a Windows XP 32 bit laptop (with both 4.1.0 and 4.2.0 drivers tested) and a Windows 7 x64 desktop (with and without 4.1.0 installed). At one point performing a file operation on the SD card actually blue-screened my Windows 7 box, which is what prompted me to return the droid to Verizon for another one, using this thread as backup.

Since I was within 30 days of purchasing it they were willing to (or had to upon my request?) swap it for a new one. The tech at the store told the sales guy he also believed it was a hardware issue although it's unclear whether he had any prior knowledge of an issue.

On a side note, the new phone's autofocus works like a charm whereas my old one’s only hope of autofocusing seemed to be the forthcoming 12/11/09 update. My guess is their first batch of phones had some issues that were resolved with a minor release with their next batch.

 

My Droid has been fine with my Apple Mac computer up until an incident today. Usually when I plug in the USB cable, I won't see the phone on my computer screen until I pull down the notification on the droid and use the prompt there to mount it. Then it appears on my desktop screen.

I've been in the habit of just leaving it plugged in (USB) while working on my computer - today all of a sudden a window popped up on my desktop screen say I had removed a device without properly unmounting it first. I had not touched the phone or any other usb device at the time. With that - all usb was gone. My keyboard, printer, disc card reader - all of it not recognized by the computer. It took a reboot to cure the issue. All has been well since. Very puzzling.

Oops! It happened again today. Phone was charging with usb cable plugged into the computer, all of a sudden all usb on the computer was gone again - screen popped up saying "device disconnected improperly". Again - I had not touched anything - not even in the room. Phone does not show any notification when the usb cable is plugged in now. I'm off to my VZW store....
