Can it be affected by noise on USB line?

The Pro iDSD/Pro iDSD Signature can be affected by packet errors the same way any USB device can. It is not, however, affected by noise on the USB power (it does not use USB power) or ground/Earth loops via USB or other inputs (because it uses galvanic isolation).
