FAQ

USB devices cannot be recognized.

	Printer （models are limited.）
	Barcode
	USB Hub
	Transfer Cable

When using a USB Hub,

When multiple devices are connected using a USB Hub, the power, 0.5A supplied from GP's USB Port may run short. When the power volume runs short, since GP monitors the power, it cuts off the USB devices. Do not use the hub and connect one USB device. Then check if it's recognized or not.
