HID Joystick Number LED's

so working on project want use usb joystick on multiple platforms without writing drivers device on multiple platforms (ugh). hid joystick profiles seemed fit, appears support input device host computer. fine except want use multiple controllers same host , when want joysticks light led proportional number of joysticks connected. first joystick lights player 1 led, second joystick lights player 2 led, etc.

i know possible via hid because read mind-numbing specification. know possible host send set_descriptor request change hid descriptor property can used turn on led. short of writing custom driver generate these requests each platform wish support (again ugh), know way me use functionality turn on led corresponding joystick numbering mentioned above?

edit 1:
after doing digging found out google filed exact feature added hid spec found in document: http://www.usb.org/developers/hidpage/hutrr47.pdf unfortunately approved month ago , if os's required implement feature in future releases, not have yet. give whirl, don't have hope.

if knows workaround please let me know. post results of trial mentioned above can.

i have same problem not dev avr.

you need reed usb hid code, translate , send ti tx how ??

if body can driver capacity i'll make donation.
