I'm on a Leo4Allv4.1 installation, USB devices aren't recognised unless they are plugged in before booting up the computer. For example my iPod gives the error in iTunes: 'iTunes has detected an iPod but cannot identify it.' This error doesn't occur if I boot up the computer with the iPod connected, the same goes for memory sticks (Leopard doesn't detect anything, but it's ther e if I boot up the computer with it plugged in.) Any ideas? Here's some hardware info:
