Dear Experts,
I am trying to create a new URB in the completion call back.
Here I am giving the code that I am using.
void my_usb_stor_blocking_completion(struct urb *urb)
{
struct urb *rr_urb ;
//
//
//
rr_urb = (struct urb*)kmalloc(sizeof(struct urb), GFP_KERNEL);
if( NULL == rr_urb)
return -ENOMEM;
memcpy(rr_urb, urb, sizeof(struct urb));
usb_fill_bulk_urb(rr_urb,
current_urb_context->pusb_dev, current_urb_context->stat_bulkin_pipe,
prd_ready, 4,
my_usb_stor_blocking_completion,(void*)current_urb_context);
//
//
//
}
With this code, the system is going to hanging.
Is there any thing I need to do while creating a URB ?
Thanks and Regards,
RD
