Frequently Asked Questions
Bi-directional, will it work in both ways?
- USB is always bi-directional.
- USB defines host and device or in terms of direction upstream (communications from device to host) and downstream (communication from host to device.
- The host is always on the upstream side and has a type A socket (or OTG) the device is always downstream and originally devices were all supposed to be fitted with type B sockets or a type A plug (memorystick etc.). A host (mostly a PC, or android on OTG) is the controlling device and an ADC or DAC is a device.
As long as the iPurifier (what ever version) plugs into a "B" type socket (or via an adapter into a "A" plug - e.g. iDSD micro) it works in the right "direction".
