can a USB port just suddenly stop working? I have my printer connected to one of my USBs. I haven't used the printer in about 2 weeks, so last night I tried printing something, and a message says "USB Device Not Recognized". So I'm like WTF? So I unplugged my printer, and plugged my datatraveller in, and same message appeared. So, then I tried again using my digital camera, and this time it worked. So I'm thinking both my printer and the datatraveller is fcuked? So just now, I tried both those devices (printer and datatraveller) on my brother's computer, and both worked. So something is wrong with my USB ports then. anyone else experience this problem before?
