hihi!!!
thks for replying!!!
but how do i use the ControlRequest() method to read
data??? i mean do i just assign the values "kUSBIn "
to rdDirection and "readbuffer" to pData as shown
below? if so, does the readbuffer store the data that
is read? pls reply!! thks alot!! cheers :-)
OUSBDevRequest request;
char *readbuffer;
request.bmRequestType = USBmakebmRequestType(kUSBIn,
kUSBVendor,
kUSBDevice);
request.bRequest = 0x1; //
request.wValue = 3d40; //
request.wIndex = 0;
request.wLength = 0;
request.pData = &readbuffer;
result = (*intf)->ControlRequest(intf, 0, &request);
