Hey ,all guys, a week before I've gotten a Christmas gift usb 3.0 hub from my brother. I have just used it for several times on my Toshiba PC ( Windows 7). It works great generally. The transfer speed firstly presents very approximate to usb 3.0. Later I started to use the charging function which seems also brilliant to me. That's the premise of my issue. Then two days when I visited my cousin, she borrowed my hub and called me last night that the charging port is not useful only for her new Ipad Air. She said it acted no sign first and then started charging slowly. I am a little confused about the case because I have no idea about the Ipad Air.
Has anybody helped me to analyse the possible causes ? Or is there any relationship between the speed of charging and the usb port or the devices they connected to ? I would love to try any proposal.
Yean, I've changed another usb ports to connect and come across the same issue. I am also considering the same situation. That's the Apple always does.
