Normally the kernel will assign a device such as sda (in addition to sg0). The kernel documentation for USB_STORAGE says that you need BLK_DEV_SD enabled. Is it? If it's modular then the hotplug scsi.agent script is supposed to load it (sd_mod). |

|

$ gzcat /proc/config.gz | grep -i BLK_DEV_SD |
| 54 |
CONFIG_BLK_DEV_SD=y |
