Simulate USB insertion on OSX via software

Question

How can I insert USB device nodes into OSX (> = 10.5), for example, could you debug USB handlers / write new USB drivers?

I am interested in this to handle non-USB devices using TokenD.

Be that as it may, I would have to fake a USB device and then create a PC / SC ifdHandler that would handle this fake device. (If anyone knows of any other way to embed TokenD, not necessarily supported by the device, let me know!).

I guess IOKit might be involved in this solution ... since this is the basic element that I need to “trick”.

Answer 1

IOKit is almost the only thing related to this, and you will need to have a good understanding of how this works before more specific answers make sense. If Apple's documentation doesn’t do this for you, Amit Singh’s book should pick up a lot of weakness, even if it's a little outdated.
