Hi, >Sorry, > >I thought this was clear. Your patch is making the assumption that the reset is triggered by the SCSI layer. You cannot make that assumption, as there is an ioctl for resetting a USB device. >In case we are getting an error during the reset (our endpoints vanish), the device driver must report that to the USB layer, so the driver will always be disconnected. >We cannot drop errors. > > Regards > Oliver This patch modified uas_post_reset to skip rebind operation to avoid exception while -ENODEV happens not drop error. If uas_post_reset happens -ENODEV, usb_reset_and_verify_device must happen error. So,when we use ioctl(USBDEVFS_RESET) to reset device, if usb_reset_and_verify_device happens error, the error will be reported through ioctl return value. Regards, Kento Kobayashi
