Hi,
I need a USB isolator, and it is not a problem of energy, the disturbances make the audioBox Ione unusable in recording, with or without connected instruments.
I found this Hifime, but it's just for low and full speed USB.

Can you confirm to me that the Ione USB audio box is Full Speed USB and not Hi speed? Thank you
