Problem with Steelseries Keyboard and Mouse or usb hub
Not sure what causes all these problems. I have Steelseries keyboard and mouse connect to a USB hub. Only when I open up Adobe software, the mouse often disconnected from the PC (the mouse still has power as the light is still on) and sometimes the keyboard's indicator light will turn off with the playback speed in Premiere Pro speed up like 2 times. Unplug and plug in again will solve the problem. These won't happen except when using Adobe stuff. So either Adobe don't like USB hub or steelseries I think.
