I recently bought a ViewSonic VP2030b LCD display, and it comes with some additional usb plugs which is convenient. However these plugs do not seem to be recognized by my current Fedora install. They were at one time working, but either through a kernel upgrade or service changes I've made, usb ports no longer work from the monitor. I used to have my joystick and wireless mouse IR plug plugged into those ports. The usb ports are getting power though because I can still recharge my mouse battery using one of these ports. The thing is that it was working once, but no longer works. Does anyone have any similar experience with this issue who might be able to give some pointers? Thanks in advance, Chris
