I am using Windows 7 and quite new with this computer stuff so I hope I post this in the right section.
When I connected my Scanner, Mouse, Keyboard, Tablet and MP4 into the USB my computer can detect this driver. But when I connect it to my pendrive, card reader and recently my portable drive, nothing comes out. Not even a bubble saying 'Windows could not detect this driver'. As if I did not connect anything. Is there a problem with my computer?
