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.
Host controller
An Ethernet cable should be used for enabling a host computer to communicate with other computers or electronic devices. The Ethernet cable is usually attached through a modem to each device, or the device can be wireless such as in Wi-Fi capabilities.
The difference between a USB host and USB OTG is simple. USB host is one device connected directly to the computer. USB OTG (on-the-go) is where a device, be it a cellphone, tablet, or whatnot is connected and used as the host.
A switch is a network connectivity device and a host is a computer system (client) on a network.
Life line a parasite canot exist with out a host.
A peripheral device, more commonly referred to as a peripheral, is a "device attached to a host computer behind the chipset whose primary functionality is dependent upon the host...". Thus, a peripheral is any device you attach to your computer which is not central to your computer's standard operation. Printers, scanners, game controllers, and security dongles are all examples of peripherals. This definition can be found here: http://en.wikipedia.org/wiki/Peripherals The term "hardware device," however, seems a redundant phrasing, since any "device" by definition would be hardware.

The relationship between a flea and cat's fur is that of parasite and host. The flea is a parasite that feeds on the blood of the host.
A peripheral is a device attached to a host computer, but not part of it.Some common peripheral devices are keyboards, printers, computer monitors
The USB Process When the host powers up, it queries all of the devices connected to the bus and assigns each one an address. This process is called enumeration -- devices are also enumerated when they connect to the bus. The host also finds out from each device what type of data transfer it wishes to perform: Interrupt - A device like a mouse or a keyboard, which will be sending very little data, would choose the interrupt mode. Bulk - A device like a printer, which receives data in one big packet, uses the bulk transfer mode. A block of data is sent to the printer (in 64-byte chunks) and verified to make sure it is correct. Isochronous - A streaming device (such as speakers) uses the isochronous mode. Data streams between the device and the host in real-time, and there is no error correction. The host can also send commands or query parameters with control packets. As devices are enumerated, the host is keeping track of the total bandwidth that all of the isochronous and interrupt devices are requesting. They can consume up to 90 percent of the 480 Mbps of bandwidth that is available. After 90 percent is used up, the host denies access to any other isochronous or interrupt devices. Control packets and packets for bulk transfers use any bandwidth left over (at least 10 percent). The Universal Serial Bus divides the available bandwidth into frames, and the host controls the frames. Frames contain 1,500 bytes, and a new frame starts every millisecond. During a frame, isochronous and interrupt devices get a slot so they are guaranteed the bandwidth they need. Bulk and control transfers use whatever space is left. The technical links at the end of the article contain lots of detail if you would like to learn more.
Most USB hard disk drives, mp3 players, digital cameras, flash card readers, cellphones and other USB digital storage devices. If it can be plugged into a PC via USB and recognized as a storage device by the PC, it will be recognized by USB Host Play devices as well. Files that can be played back depends on what your USB Host Play device supports. Most will play back JPG and MP3 at the very least. Others can play MP4, DivX, WMA, WMV files also.
