I have a Hp Mini Notebook 3741-TU. at first it worked with no problems, when I insert a usb cardreader to an existing port on the right ports are still working perfectly. but after I was off and I try to insert usb modem was not working perfectly not even a command that the usb is working or not (zero at all). Until now these ports can not be in use. explanation please, thank you.
