Will using USB 1 and USB 2 devices in the same desktop PC that has USB 2 ports slow down performance because of the USB 1 device being added to the system? I know that if you use a USB 2 hub and add a USB 1 device to it that the entire hub slows down to USB 1 speed. But Im interested to know if the same thing can happen to a PC if you're not using a hub, just the computers ports. Here is my concern... I have a USB 1 midi keyboard and a USB 2 audio interface (soundcard) Sound quality is obviously very important when it comes to music production.. Im concerned that the USB 1 midi keyboard might slow the USB 2 audio interface down to USB 1 levels which would be a disaster for processing audio signals. So does anyone know what will happen? Thank you for any help!!!!
