I have a laptop dell inspiron d1420 that came with Windows vista and I upgraded to Windows 7 ultimate, I noticed that when I plug in a USB mass storage, when I try to remove it, I don’t get the the safe to remove message and lately when I try to remove it, I keep on getting the message it’s busy and I can’t remove it. I tried the same USBs on another PC and I have no problems at all. I connected a printer USB cable and wondows didn’t llok for the driver neither didn”t install the printer, it left it as unspecified device with the name of the printer but i can’t print. I tried with another PC running also Windows 7 ultimate and i got no problem, windows installed the driver, considering i used the same printer and same cable. What’s wrong with my 4 USB ports and how to fix them?
