No apple does not put USB plugins in the iPads
Your iPad came with a usb cord that attaches to your iPad with the big end and the other end (the one with the usb plug in) goes into your usb slot on your computer.
No
You get the iPad its self, the USB charger with socket adaptor, you get the owners manual and two apple stickers.
The USB Port on an iPad is for either charging, or syncing media (music, apps, etc.) to the device.
Yes it has. And i think you should use the apple usb cable with an ipad but not all the cables fit.
No,ipod and ipad are two very different types of technology where as the iphone does have a chance of charging with the ipad usb adapter.
iPads do have usb ports. You just have to buy an adapter
none
USB ports, unlikely. Mac OS X, no this is impossible as the iPad is not a Macintosh.
iPads cannot use USB modems.
You cannot use a USB storage media for sending storage on an iPad. You need a computer with iTunes. You could make a backup using iTunes and store that backup on a USB drive, but you still need iTunes to restore it to the iPad.
No, The port on an ipad is a device port, not a host port. You would have to get a USB on the go adapter for iPad to connect external devices.
