I'm not sure computer setting or what, drivers etc.. But when syncing or my iPad is plugged into my computer I notice at times it gets disconnected - then reconnects itself.

Does this happen to anybody? Solutions?
 
If this is in Windows it may be that the USB host is erroneously detecting a sleep state and shutting off power to the port momentarily. Try going to Device Manager and locating, under USB controllers, which root hub (or whatever your system calls it) has the iPad connected and disable "allow computer to turn off this device to save power."

^thanks

I've looked up in USB under device manager seem to have found it "Apple Mobile Device USB Driver" but right clicking only shows Update driver/Uninstall/Scan for hardware changes

I dont see the allow computer to turn this device off option
 
Which OS are you running specifically? That'd make it easier for me to tell you exactly what the item is probably called. It'll *probably* be under something like "USB Serial Bus Controllers" at the bottom of the list of items in Device Manager. Expand that out, and maybe under an item called "USB Root Hub", for which you will see multiple entries if you have multiple USB ports. You'll have to find the one to which your iPad is attached. Under a tab such as "Power Management", you'll see the option to power down the device.

I'm on Windows 7 OK think I found them they are listed as USB Root Hub

All of them well aside from one are unchecked, should I go on and "check" them?

You want the box unchecked if the problem is the port is cutting power due to an erroneous detection of idle state.

Not good with computers sorry ok have gone and done that, and hey its always cut in and out right after plugging in so far hasn't disconnected me. I even synced and backed up.

No worries. I wasn't frustrated. I was just trying to make it very clear so that I could be as helpful as possible.

Good luck! Let us know what happens :)
