Yes you can.
I use MultiMiner that way I can control which units mine which coins, as well as run my GPU's for scrypt and now even the DualMiner in Scrypt only mode.

Topic: Can I run a couple USB miners on same rig that is scrypt mining? (Read 564 times)

I run 1 cgminer instance per GPU in a shared rig (each GPU is owned by different person and mines to different account). I Also ran cgminer on it for mining block erupters/antminers, but I prefer bfgminer.
EDIT: usb miners use com ports like COM1 COM2 COM3

i run cgminer for gpu's and bfgminer for usb devices as well as a slush proxy for my cube... that way i dont have conflict of instances or overlap problems.

Normally I set cgminer to device 0-2 for my 280x's but not sure how I would tell it the device # for the USB stick. Anyone done this? More for fun than anything else.
why not? Simply run two instances of CG miner and set the first instance that runs scrypt to ignore USB:
--usb :0 will disable all USB I/O other than to initialise libusb
Then run the 2nd instance to:
-usb 1:*
I got this info from here: http://ck.kolivas.org/apps/cgminer/README.
I think I'm planning to do the same thing when I put together my Scrypt rig
