Our firm recently acquired 2 Acer Aspire S3 Ultrabooks , 1 Win7 the other Win8. These machines are sleek, fast, light- very nice, but for one oddity. Both machines have 2 USB 3 ports on the back - which work well with peripherals plugged straight in, but when a hub is introduced, no USB peripherals work. I have tried passive 1.0 hobs, powered and unpowered 2.0 and 3.0 hubs - none work, but work fine on other machines. Any thoughts?
