thks barry for the invaluable advice!!!
sorry for bothering u guys again but then
was just wondering for the ControlRequest method, how
do i know the values of request.wValue,etc. i have
already read through the documentations but they are
kind of profound so could anyone explain a little more
in dept to me? Thanks!!! :-)
OUSBDevRequest request;
char *readbuffer;
request.bmRequestType = USBmakebmRequestType(kUSBIn,
kUSBVendor,
kUSBDevice);
request.bRequest = GET_LUM_CTL; //
request.wValue = BRIGHTNESS_FORMATTER; //
request.wIndex = 0;
request.wLength = 0;
request.pData = &readbuffer;
result = (*intf)->ControlRequest(intf, 0, &request);
