Actaully i have returned again to usb_bulk_msg with timeout set to
zero so it Builds a bulk urb, sends it off and waits forever until it
is completed.
and here is my simple application that uses the skeleton module:
*********************************************************************************
do
{
insize =read (fd,(char*)inbuff, sizeof (inbuff) );
printf("insize is %d\n",insize);
printf(" %s\n",inbuff);
}while (strcmp(inbuff,"end"));
****************************************************************************************
my aim is : when the gadget sends any word to the host, the latter can
read it using the usb-skeleton module and prints the data received and
its size as shown in the previous code.
so when the gadget is sending "hello" for example,the host really receives it
"hello" and the insize is 5 and then prints insize is -1 forever
as follows:
insize is 5
hello
insize is -1
insize is -1
insize is -1
insize is -1
also the sending side of the gadget is closed ?
so how can i solve this.i dont want the phrase of insize is -1 to be printed .
i just want the output to be
insize is 5
hello
then it stops printing until the gadget sends another thing
how can i achieve this?
