Is it possible?]]> Device absolutely functional, because example set-led is still working. I read sources of this example and sources of a driver: "libusb-win32-filter-bin-0.1.12.1".
To light-on led indicator I trying to use in Delphi:

Code: 

 cmd[0]:=$01;
 cmd[1]:=$00;
 cmd[2]:=$00;
 cmd[3]:=$00;

 //$80C LIBUSB_IOCTL_VENDOR_WRITE
 DeviceIOControl(HidHandle,$80C,nil,0,addr(cmd),4,res,nil);

No result.

Where I can find examples or documentation how to work with this device using native windows API functions? Or, maybe, you can do this?
