USB isolator on Mac OS

[amadeuspzs]

Hi there,

I purchased a ADUM3160-based USB isolator, which looks identical to the recommended one.

However, whether it's in low speed or high speed mode (on board switch), it isn't coming up on Mac OS under /dev/tty*.

I've googled and can't see anything obvious like a driver, so wondering how others have found this to work?

Thanks,

Amadeus

I think from your description it might be faulty.
An isolator is not an extra device on the USB bus (and requiring drivers), it should be transparent to the computer. It is simply isolating, not doing anything else.

Yes of course, it shouldn't need a driver.

I tried it on a USB mouse and nothing, so looks like it's defective.
