i have a assembled pc with amd phenom 2 processor and gigabyte ma74gmt-s2 motherbord .
i have a problem with usb ports . i am using usb keyboard . when only keyboad is connected at back it works fine but when i plug any other usb device at the back keyboard gets undetected . If i re plug the keyboard the device connected gets undetected . so me able to use only one usb port at back . please help me.
No . keybord is not working in front even if none of the device are connected at back . even i cant use external harddisk at the front . only pendrive and music players i can use at front. is any possibility of this problem by OS ?
One of my friend told me to disable the USB chipset . withought thinking much i disabled it but mine is USB keyboard and couldn't enable it back . then i got ps2 keyboard from my friend and enabled it . now its working fine
