Help Phone reboots when plugging in USB cable

Ever since the 2.2.1/2.3.34 update "almost" every time I plug my phone into the computer it does a sort of quick or short reboot, then works fine with the USB plugged in. It doesn't seem to matter if the last time I was connected was with charge only or with USB Mass Storage selected. This just started happening after the update, worked fine before and I've had no driver changes or anything.

Any ideas?
 
Mine is doing the same thing- every time I disconnect from charging, it reboots. And today, it just rebooted out of nowhere.

It has happened since the OTA update.
 
Ditto. AND, it decided to reassign every ringtone and notification sound I have set afterwards. I never has this happen until I plugged in the USB to my PC. I rarely ever do that anyway, but it REALLY jacked everything up on top of the reboot. Smooth, Moto, real smooth!!!!!!!!:rolleyes:
 
Aha! Mine has been rebooting randomly since the update too, but I couldn't figure out why. I suspect this is the issue since I'm forever plugging it in/docking it/unplugging it. Good to know I have company. :confused:
 
I'm guessing either none of the experts know a solution or haven't experienced it......?

I froze LPP, used Go Launcher and froze some other apps, and this morning when I disconnected from the charger, the phone did NOT reboot.

I switched back to LPP (Go launcher wasn't allow the screen to be killed) so I'll give it a try again tonight and see if the reboot happens. If it doesn't, I'll look at what apps I froze yesterday.

How do you "freeze" apps?

You think LPP caused the problem? I've been using LPP for a while and this problem just started with 2.2.1/2.3.340

I'm rooted and use Titanium Backup (paid) to freeze the apps. Learned the hard way when I uninstalled bloatware and couldn't update. Now I just freeze.

Switched back to LPP and have reboots randomly and when disconnecting from charger. I, too, had LPP before the update, but I think something in this update might be messing with LPP. I read somewhere LPP wasn't getting a major overhaul until April.

So right now, I'm back to stock home and will see how things go.

UPDATE: No reboots on stock so far, including taking it off the charger.
 
Mine did this last night when I plugged in to my TV (to charge, but it still reads the SD card) and today at work. Strange. Anyone else O/C at all? Mine was at 1.2Ghz and I went back to stock to see if it makes a difference. It doesnt do it everytime I plug in with Mass Storage selected though, as I tried it about 10 more times with other computers today and it didnt do it again.

I don't O/C has anything to do with it, mines completely stock 2.2.1, and your symptoms are the same as mine - it's random, sometimes it does it sometimes it doesn't. and always works fine after it does it. Weird.
 
Update: Just had my first random reboot of the day. Didn't happen, though, when disconnecting from charger.

No clue where the problem is.
 
Has anyone done a data reset and this be fixed? Also is anything being corrupted when it reboots? If something like this happens to a windows computer there could be serious problems caused by it.

I guess not or they're not telling. Surely there's more than a handful of people with this issue.....?
 
Reboots when I plug in the USB sometimes too. I thought it may have been because I rooted, because it didn't do this beforehand, even with the update. Granted, I've only had the phone for a little over a week and rooted a few days after buying it, so I never really plugged it in the USB too often before rooting.
 
I was able to resolve this issue by moving my apps to back to my phone from my SD card. If you are still having this problem (and have nothing running from the card), I would suggest you take this step to rule out open handles to files on the card:

a) Shut phone down > Pull SD card > Boot phone back up > plug into computer.

b) Terminate ALL apps using an app killer, then plug into the computer.

This will help you determine if something has an open handle to a file on the SD card. I believe it is a kernel panic of sorts that was causing my 'insta-boot.'

I think you may have something there. My only reboots occur when plugging in the USB cable: first a Win Explorer window pops open with the "read-only" Moto partition, then the phone reboots, then eventually I see an Explorer window with the SD data partition. This seems to indicate the problem lies with un-mounting the SD card.

I've moved the few apps I had on the SD card to the phone (I have plenty of room). We'll see if the reboots continue...
 
I backed up my apps with My backup pro, transferred just that folder off my sd card to my computer, did a factory data reset and formatted my sd card almost 2 weeks ago. Since then not a single reboot.

I just had this "quick reboot" on usb connect start happening today. Everything has been fine before that.

How do I move the apps to the phone?

From a "home" page, press the Menu key, then Settings -> Applications -> Manage Applications, then select the "On SD card" tab. For each application, tap on it, then click on the "Move to phone" button half way down the screen. (This is how it works on my Droid X with Android 2.2.1).

This process has sucessfully prevented the "re-boot afer USB connection to PC" issue for me.

Thank you for that. I found that the only app was my Aldiko book reader and I moved it ....
