Good afternoon! Mga bro, I got a problem of IBM Thinkpad R40. It won't detect any USB devices. Have tried hard disk enclosure both usb 1.1 and usb 2.0 but it couldn't detect either. I also tried flash disks usb 1.1 and 2.0, still won't work. I just post this topic to get some useful tweaks, advices and solutions inorder to resolve this problem. Thanks in advance.
