I have a Maxtor 3200 external USB HDD. I've tested it on 3 different dual-boot computers (2 desktops, 1 laptop) and I have the same symptoms on all 3 machines.

In Win7 the drive is recognised and works no problem. In Ubuntu 11.10 (64) I get the following:


Apr 8 18:38:09 jim-home kernel: [ 847.876567] hub 1-1:1.0: unable to enumerate USB device on port 3
Apr 8 18:38:09 jim-home kernel: [ 848.132240] hub 1-1:1.0: unable to enumerate USB device on port 3

Apr 8 18:38:11 jim-home kernel: [ 849.666405] hub 1-1:1.0: unable to enumerate USB device on port 3
The drive is currently formatted as NTFS but I have previously tried ext2 and ext4. I've also tried a fresh Ubuntu install but nothing works. It's supposed to be a plug-and-play device so I'm assuming it's not a driver problem. Any ideas?

Update #1 I've tried a fresh install of 11.10 32bit, still getting the same error.

Update #2 10.10 32bit (kernel 2.6.35) still the same thing.

Hey jim_deadlock,

Sorry I am just giving you a link to a forum, but I found this helpful.

Unable to detect HDD (https://bbs.archlinux.org/viewtopic.php?pid=1040087)

I also had this issue with "unable to enumerate on port 1". I just temporary disabled ehci_hcd. I DO NOT recommend blacklisting or deleting ehci_hcd or you WON'T be able to use your usb ports.

Here is another forum I found helpful for this general usb enumeration issue:

USB not working properly (https://bbs.archlinux.org/viewtopic.php?id=114077)

Let me know if this helped at all.

All the best,

In the end I cracked open the plastic box and took out the HDD which works fine as a normal drive. It was the USB parts which must have been worn out or whatever.

Ok. Glad to hear it was fixed in the end.

Having the same problem with HP printer.
Solved by unloading usb-storage module.
Seems somehow usb-storage is trying to handle the printer.
