force usb enumeration?

From: Matt Keys 
I have a problem enumerating a usb drive at boot. At the moment, I can only
get ubuntu "see" it by unplugging and replugging the drive after the system
is fully up. :


Another oddity, the disk has a strange uuid. I don't know if that's because
it's NTFS or what. I've seen other examples out there on the net with
similar uuids on ntfs. I've tried telling fstab to use both /dev/sdc1 and
the strange uuid, both fail as it doesn't see the device at all until it's
manually replugged. After replugging it will show up on blkid :


/dev/sdc1: LABEL="Seagate Backup Plus Drive" UUID="D6D4E78DD4E76E65"


Also in /dev/disk/by-id or by-uuid :


mkeys@server:~$ ll /dev/disk/by-id/ |grep sdc1

=============================================================== From: Matt Keys ------------------------------------------------------ I'm not sure wtf is going on with it. I just repartitioned it and reformatted as ext3 thinking it may just be ntfs screwing with it. That cleared up the weird uuid, so I put that in fstab and tried again. Ubuntu still prompts me at boot to "Press S to skip" for the missing disk at boot. The system goes to sleep after there's no activity. As soon as I replug it, it was mounted on /usbhd : [ 85.398048] usb 4-1: device descriptor read/8, error -110 [ 85.500145] hub 4-0:1.0: unable to enumerate USB device on port 1 [ 121.084055] usb 1-5: new high-speed USB device number 8 using ehci
