This makes the Carelink stick show up on usb 2.0 ports on Mac.

(But it doesn't work) Try using the prolific driver? There does seem to be a general serial driver from Apple...
Can also try using wdreg to use Medtronic's own Jungo kernel driver!!!

When installed, it looks like this:

$ ls /dev/tty.Carelink-000013FD 
/dev/tty.Carelink-000013FD
bewests-MacBook-Pro:~ ben$ 

bewests-MacBook-Pro:~ ben$ ls /dev/tty.AsantePorter-FTX1MKWH 
/dev/tty.AsantePorter-FTX1MKWH
bewests-MacBook-Pro:~ ben$ 

See https://gist.github.com/bewest/6488955 for more info on what makes the carelink stick incompatible with usb 3.0 ports.

I've verified the above method using a common usb 2.0 hub as an intermediate link between a usb 3.0 port on a new macbook pro as of this writing.
