Ok,so i've been dealing with the same problem 2 days ago. My computer doesn't recognize my iPad as a device whenever i connect the USB port into the usb 2.0. I tried to check the Autoplay content under control panel -> Hardware and sound,and as i see,the device list were blank. I also checked iTunes to see if it's listed,and it's just the same,no device were found. My iPad,somehow,is listed as a portable device into my computer,and is named as "Apple ipad" even though i named it "lance". Although i can view my pictures from my iPad through computer,i still can't sync on iTunes. I tried to re-install my iTunes,reboot my iPad,and use a different cable usb,but it didn't work.Is there anyway to fix this.Please comment,thanks!
