The device causes * very long delay in boot process of these platforms which is a big * performance issue. Improvement in firmware may solve the issue, but * before the firmware is fixed, it needs to be taken care of by software * to avoid the huge impact on user experience. * * The long boot delay is caused by timeouts and retries of READ CAPACITY * command issued to the device. The device is a USB ufi subclass device * using CBI protocol. When READ CAPACITY command is issued, the device * returns STALL on the bulk endpoint during the data stage, however, it * doesn't return status on the intr pipe during status stage, so the intr * pipe can only fail with timeout. * * Reducing timeout value to 1 second can help a little bit, but the delay * is still noticeable, because the target driver would make many retries * for this command. It is not desirable to mess with the target driver * for a broken USB device. So adding the device to the scsa2usb blacklist * is the best choice we have. * * It is found that the READ CAPACITY failure only happens when there is * no media in the floppy drive. When there is a media, the device works * just fine. So READ CAPACITY command cannot be arbitrarily disabled. * Media status needs to be checked before issuing the command by sending * an additional TEST UNIT READY command. If TEST UNIT READY command * return STATUS_GOOD, it means the media is ready and then READ CAPACITY * can be issued. * * SCSA2USB_ATTRS_NO_MEDIA_CHECK is added below for this purpose. It is * overrided in scsa2usb.c for the AMI virtual floppy device to take care * of the special need. */ #define MS_AMI_VID 0x46b /* VendorId of AMI */ #define MS_AMI_VIRTUAL_FLOPPY 0xff40 /* PID for AMI virtual floppy */ /* * List the attributes that need special case in the driver * SCSA2USB_ATTRS_GET_LUN: Bulk Only Transport Get_Max_Lun class specific * command is not implemented by these devices * SCSA2USB_ATTRS_PM: Some devices don't like being power managed. * SCSA2USB_ATTRS_START_STOP: Some devices don't do anything with * SCMD_START_STOP opcode (for e.g. SmartMedia/CompactFlash/ * Clik!/MemoryStick/MMC USB readers/writers. * SCSA2USB_ATTRS_GET_CONF: SCMD_GET_CONFIGURATION is not supported * SCMD_TEST_UNIT_READY: for floppies this needs to be converted to * SCMD_START_STOP as floppies don't support this * SCSA2USB_ATTRS_GET_PERF: SCMD_GET_PERFORMANCE not supported by * Mitsumi's CD-RW devices. * SCSA2USB_ATTRS_BIG_TIMEOUT: Mitsumi's CD-RW devices need large * timeout with SCMD_START_STOP cmd * SCSA2USB_ATTRS_RMB: Pay attention to the device's RMB setting, * instead of automatically treating it as removable * SCSA2USB_ATTRS_USE_CSW_RESIDUE: Some devices report false residue in * the CSW of bulk-only transfer status stage though data * was successfully transfered, so need to ignore residue. * SCSA2USB_ATTRS_NO_MEDIA_CHECK: AMI Virtual Floppy devices need to * check if media is ready before issuing READ CAPACITY. * * NOTE: If a device simply STALLs the GET_MAX_LUN BO class-specific command * and recovers then it will not be added to the scsa2usb_blacklist[] table * in scsa2usb.c.
