I am using ThinkPAD T41. I am pretty sure I have two USB2.0 ports. But recently, whenever I connect a external harddrive or flash drive with USB2.0 to my laptop, I always get this message:
"This USB device can perform faster if you connect it to a Hi-Speed USB2.0 port.".
Looks like my USB2.0 ports became 1.1 or 1.0, and the speed for copying or moving files does significantly slow down, just like I am having a USB1.0 port on my laptop.
Cannot figure out what the problem is. I did a Windows update lately, not sure if that was the reason (There are just too many bugs in Windows). I also found a virus (Win32.Troj.Daemonize.aw.14336) on my computer last week and I think I have got rid of it.
I hate the slow USB speed. Can somebody help me? Thanks a lot.
