Hu Jan and everyone. I believe you're can help me.
Here is set of descriptors

My device recognized by Windows and I can send bytes:
HANDLE file=CreateFile(ptrDetail->DevicePath,GENERIC_READ|GENERIC_WRITE,
FILE_SHARE_WRITE|FILE_SHARE_READ,
(LPSECURITY_ATTRIBUTES)NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
0);
char arr[6] = {0x0,0x31,0x02,0xA1,0xA2,0x13};/
WriteFile(file,arr,6,&sended,NULL);
But I can't perform Readfile():
char rxArr[20];
DWORD received;
memset(rxArr, 0, 20);
ReadFile(file,rxArr,3,&received,NULL);Here program causing loop and I can't retrieve answer.
I.e. Reading not working.
If look at USB BUS using logic analyzer i see OUT packet when program perforw WriteFile() (PId, Address etc. all OK)
When host perform ReadFile() - NOTHING.
I think USB driver block my request.
