I would suggest you use caution with larger peripherals such as scanners or big printers that run directly off the USB port. Joysticks, mouse, & keyboards don't draw too heavily in most cases.
You'll have to check the volts and ma(micro amp) demands of the peripheral you intend to use, against the stated limits of volts and ma your USB card supplies. If your peripheral uses less than your card you are probably ok, but not the opposite where your card is less than the peripheral.
