My device is implementing a new Mass Storage Protocol UAS (USB Attached SCSI). So, i do not think existing usb-storage would work for this device. Moreover in my stack with simulator i'm directly redirecting the submission of URB to simulator. I had removed usbcore and host from the stack for testing simulator. Also, I'll look to gadget device for any details. I would like to know what is needed to be handled in simulator so that SCSI layer sends SCSI commands to storage and then to my simulator.
