I don't know if you already solved this, but I got 2 of the 144KH/S-280KH/S USB LiteCoin miners running on my Mac - El Capitan by doing the following:
Download, build and install dmaxl/cgminer:
./autogen.sh
./configure --scrypt --enable-zeus
make
Find the USB sticks using:
ls /dev/ | grep SLAB
cu.SLAB_USBtoUART
cu.SLAB_USBtoUART20
tty.SLAB_USBtoUART
tty.SLAB_USBtoUART20
I tried both the tty.SLAB_USB* and cu.SLAB_USB* devices, only the cu.SLAB_USB* seem to work. Make sure the switch is in the proper position on each USB stick (switches to the right)
Startup cgminer using the command:
sudo ./cgminer --scrypt --zeus-chips 1 --zeus-clock 144 --zeus-nocheck-golden --url stratum+tcp://us.litecoinpool.org:3333 --user user --pass pass -S /dev/cu.SLAB_USBtoUART -S /dev/cu.SLAB_USBtoUART20
The output looks like:

You can adjust the clock frequency, provided you have a fan.
I can't tell if these are miners or USB drives:
Capacity: 8G U disk– Nick ODell – 2015-01-22T19:47:58.157AH. I think they are a bit of both. They come with a 8GB built-in storage capability (which shows up on my Mac Finder as a couple of folders with some apps and drivers. The drivers are Silicon Lab - so I went to the web site here : https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx and found the MAC version of the drivers (installed them) and still no luck. The device is a Miner by functions. The memory is a small add-on. Does this help?
