Help Connecting e-Bot CCTV to IPAD using USB

Hi. I need to know if there is any device that I can use to connect a Hims E-Bot CCTV to my iPad (5th Gen or any other iPad) using the e-Bot's USB cable. We currently use the wireless connection but it lags and is making my son very frustrated. The USB is much more reliable but only works with our computer (desktop unit) but this is problematic cause he can't write while using the computer connected to the E-bot at the same time. The iPad works fine when we use a stand placed right in front of the E-bot but the lag is putting him off working with it. Please help me! Thanks!
