I have a Seagate backup plus 3TB usb3 drive that seems to be recognized. I get no /dev/sdx device associated with it unless I unplug it and plug it in after the kernel is loaded. I can see this. Bus 004 Device 002: ID 0bc2:a0a1 Seagate RSS LLC But the light on the device turns completely off and I have no /dev/sdb Once I unplug it and plug it in again, the light comes on. Bus 004 Device 003: ID 0bc2:a0a1 Seagate RSS LLC And the /dev/sdb is created. Relevant dmesg output. http://pastebin.com/3DXFyGCf -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
