Is there anybody here has a problem with USB transfer speed on Windows 8.1? I already tried many thing, including updating the BIOS, checking the drivers, but it only get 3MB/s each time i transfer a data/file from my HDD to USB Flashdrive! The weird thing is, it difference if i'm using Windows 7 (with the same PC), i get normal speed at about 30-40MB/s! Just FYI, i'm using Jetway HI08 Motherboard. Is there anybody experience the same as i do? Any help would be much appreciated! Thank you.
