My 1TB USB 3.0 was working fine earlier in Ubuntu as well as Windows. But lately it is not at all being detected in Ubuntu. It still works fine in Windows. I did update my Ubuntu to 12.10 but I am not sure if that caused the issue.

When I connect my HDD and run dmesg | tail:

[   47.804676] usb 4-3: >Device not responding to set address. 
[   48.008575] usb 4-3: >Device not responding to set address.

[   49.251907] hub 4-0:1.0: >unable to enumerate USB device on port 3

The output of sudo fdisk -l is :

/dev/sda and /dev/sdb are my 2 internal HDDs. But the external one which should be /dev/sdc is not even being shown though it is connected and the LED on the HDD is glowing.

Someone had suggested adding blacklist uas to /etc/modprobe.d/blacklist.conf. Tried that as well. But still not working. Can someone help me out.

I found some info here : link. It seems to be caused by kernel. I will go home and check it properly. –  Yathi Oct 30 '12 at 12:43

I am not sure if this will resolve your issue, but it's worth a try :

Connect your Device

Pull the usb cable just a little bit out from the computer side.. ( just a tiny bit) and wait for a couple of minutes..

if it starts working then you may push the usb - cable back in properly.

I faced similar issue..

If it doesn't work then sorry.. :(

No I tried that. It doesn't do any thing. No msg or pop up or anything :-( –  Yathi Oct 30 '12 at 10:48

I have a similar case and I am using an Asus laptop N53SV. My portable drive is a 1TB Transcend StoreJet 25H3P USB 3.0. It can't be detected in the USB 3.0 port located on the left side but it is being detected on the left side ports (USB 2.0). I read somewhere in the net to turn the laptop off and then plug the 1TB USB 3.0 on the USB 3.0 port and then turn the laptop back on. This is not the grandest solution that I've got but it works. I am on 3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:33:09 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
