For procedures on checking host controllers, “Checking Your USB Host Controllers”.(p. 43)[Action to Take] ㊍ Connect the USB cable from the touch panel to another open USB port on the computer. When you do this,Plug & Play may start up and device driver installation may start.• For information on Plug & Play, see “Connections and Plug-Ins”. (p. 16)After the device driver is installed by Plug & Play, check whether the connected touch panel works or not. ㊎ If the touch panel does not work after performing ㊍, or if the USB bandwidth error reappears, connect aUSB 2.0 hub to the USB port connected in ㊍.Then, connect the touch panel to that USB 2.0 hub.• Even though a USB 2.0 hub has multiple USB ports, usually only one touch panel can be connected to it.NoteErrors that do not affect touch detection, such as momentary communication errors, are restored automatically.
