I would like to make some some newbie questions:
I just got USB-Stick Miner bitshopper GekkoScience 2Pac, I setup cgminer 4.10.0, (compiled it with icarus) and started mining.
Without changing anything the hash rate is far below expected: in slushpool it is from about 100Mh/s till about 1Gh/s, usually about 300-600Mh/s.
I have connected it to a usb port on my PC (till the hub I ordered is here). Is that responsible for low hash rate?
What I see in cgminer is:

Code:

Block: c10a02e5...  Diff:679G  Started: [18:47:13.951]  Best share: 557
--------------------------------------------------------------------------------
 [U]SB management [P]ool management [S]ettings [D]isplay options [Q]uit
 0: AMU GS-10013:                         | 1.504G / 554.8Mh/s WU: 7.0/m

Is it OK? Shouldn't I see some frequency? How can I alter frequency?
When I try to start cgminer with

Code:

sudo ./cgminer -o stratum+tcp://eu.stratum.slushpool.com:3333 -u ME --gekko-compac-freq 200 --gekko-2pac-freq 150

I get

Code:

./cgminer: --gekko-compac-freq: unrecognized option

Thank you!
