CGMINER start issue

[RelBIT]

Bitcoin Client Software and Version Number: CGMINER V4.9.2

Operating System: Windows7 SP1 @ 64 bit

System Hardware Specs: Intel Core i3 @1.92 GHz; 16GB RAM; SSD @ 128GB 30% free; HDD @ 500GB with 200gb free; ORICO powered USB hub; 2 x Gekkoscience BM1384; 802.11N network connection to ADSL/2 internet connection.

Description of Problem:
1. Using two BM1384 plugged into USB hub on batch file start gets a "COMPAC nn attempted reset got err:(0) LIBUSB_SUCCESS".
2. Using one BM1384 plugged into USB hub on batch file start runs OK - after a minute or so, when I plug in second BM1384 produces the error above.
3. Stop and restart CGMINER with single BM1384 then plug in the second one several times and it eventually recognises the second BM1384 and processes without issue.
4. How can I make CGMINER accept the two BM1384's on start; or how can I make it accept the second after start without creating the error?
5. Start script is: C:\cgminer-gekko-win32\cgminer -o stratum+tcp://cn.ss.btc.com:3333 -u username -p password
6. Searched high and low for an answer for this - posting this is my last resort. Thanks!

You need to specify the usb or com ports in the bat file. when you plug in the miner it will assign a com port to the usb you are plugged into. this is my bat i use to run 4 at a time

 cgminer.exe -o stratum+tcp://127.0.0.1:3333 -u user -p x --nocheck-golden --chips-count 128 --ltc-clk 220 -S //./COM5 -S //./COM6 -S //./COM7 -S //./COM8
