 The second version
   --usb BAS:1,BFL:1,MMQ:0,ICA:0,KLN:0
 allows you to specify how many devices to choose based on each device

+driver cgminer has - the current USB drivers are:
+AVA, BAS, BFL, BF1, DRB, HFA, ICA, KLN and MMQ.

 N.B. you can only specify which device driver to limit, not the type of
 each device, e.g. with BAS:n you can limit how many BFL ASIC devices will
 be checked, but you cannot limit the number of each type of BFL ASIC

 Also note that the MMQ count is the number of MMQ backplanes you have
 not the number of MMQ FPGAs
