decoding my analyzer

[ulao]

Need some help decoding my analyzer.

This is a snap of a control transfer but I need to convert this to software. Where is the Rid and type?

Ok I was missing my setup, still not sure shy this is not working.

In the setup I see it's a control transfer : device to host, class, interface, guessing report ID 0 and a size of 6 request 09 (set report) with report ID 0 and an out (02) . In my software I see that exact same thing but my data (data1) is something like ff,50,6d,b6. And on my analyzer I see the right data I would expect, 0,6,0,0,0,0 guessing again rid,size,d0,d1,d2,d3 - but a bit confused at why only 4 bytes. Unless the first two are data and just a coincidence.

this code shows my confusion. I do get 6 bytes but the data part is nothing like I see in the analyzer.

Code: [Select]

case HID_REQ_SetReport:// (09)
if (USB_ControlRequest.bmRequestType == (REQDIR_HOSTTODEVICE | REQTYPE_CLASS | REQREC_INTERFACE) )
{
if (USB_ControlRequest.wValue == 0x0200) //out report ID 0
{
uint8_t  ReportData[USB_ControlRequest.wLength];
test[0]= ReportData[0];//255
test[1]= ReportData[1];//80
test[2]= ReportData[2];//6d
test[3]= ReportData[3];//b6
test[4]= ReportData[4];//2
}
}

was a lufa issue. Needed to add

         Endpoint_ClearSETUP();
         Endpoint_Read_Control_Stream_LE(ReportData, ReportSize);
         Endpoint_ClearIN();
