Question:
Are all 3 USB ports in 4000/4500 USB2(480Mbps)
On Acer site the specification for 4000 and 4500 says 3xUSB2 ports
But when my friend checked it with Sisoft sandra on 4000series it reports only one port with USB2 (480Mbps) and and the remaning two as USB 1.1 (12Mbps)
(I thing the 4000 and 4500 share common motherboard so its gonna be same across all the 3 series)
Have any one connected some High speed device(USB2) and checked if all the ports are USB2 as Acer says in specification
TM 4000 and 4500 series owners please give your input
Answer:
I have a 4001WLMI and i think that al least the two ports on the right side of the notebook are 2.0, because i connected a usb pen usb 2.0 on both ports and they perform equal (faster than a 1.1 device).
Answer:
