This 10 * describes in detail the protocol used to communicate with such 11 * devices. Clearly, the designers had SCSI and ATAPI commands in 12 * mind when they created this document. The commands are all very 13 * similar to commands in the SCSI-II and ATAPI specifications. 14 * 15 * It is important to note that in a number of cases this class 16 * exhibits class-specific exemptions from the USB specification. 17 * Notably the usage of NAK, STALL and ACK differs from the norm, in 18 * that they are used to communicate wait, failed and OK on commands. 19 * 20 * Also, for certain devices, the interrupt endpoint is used to convey 21 * status of a command. 22 * 23 * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more 24 * information about this driver. 25 */ 26 27 #ifndef _SCSIGLUE_H_ 28 #define _SCSIGLUE_H_ 29 30 extern void usb_stor_report_device_reset(struct us_data *us); 31 extern void usb_stor_report_bus_reset(struct us_data *us); 32 extern void usb_stor_host_template_init(struct scsi_host_template *sht, 33 const char *name, struct module *owner); 34 35 extern unsigned char usb_stor_sense_invalidCDB[18]; 36 37 #endif 38
