"unable to enumerate USB device"

DennyCrane · #1 28th May 2008, 03:05 AM

Background: I upgraded from F8 to F9 using the DVD. I had to fix my repos because they were all still F8. Then I had to do a yum clean all to fix a host of other problems that seem to have been left over... after that a message immediately popped up for a ton of updates, so I did those updates, and, for good measure, I restarted my system....

Directly after making the updates and restarting, I now get the following error during boot:

hub 1-0:1.0: unable to enumerate USB device on port 2

The USB device is my mouse. I tried on port 1 and it gives the ~same error. I do not get that error for my external USB drive (though I've always gotten a message about assuming a drive cache, or something).... The mouse seems to work fine despite the error..... But what does the message mean, and how might I resolve whatever it is complaining about?

I get a couple of these too. If you do a search around you'll find a few others do as well. From what I've read it's nothing to worry about although I can't tell you why it happens.....

There is a bug in bugzilla for that
See HERE

So many reports - no answers !
What is happening,people?

I have the similar problem, reported in bugzilla

https://bugzilla.redhat.com/show_bug.cgi?id=457396

and I found others and the interesting part is that more that 2 months the bug status remains NEW !!!

M4rc0 · #5 7th August 2008, 05:23 PM

Yes i get that too, on all my 3 ports.

Like scotty38, I've also heard that is nothing to worry about.

But a bug is a bug

nobody likes bugs.

If anybody knows anything about this, post in this thread please.

Nope. I upgraded from Fedora 7 to 10 two weekends ago. Since then I've had copious complaints like this in my logs and spewing up the console during boot. Booting takes many minutes. Last night my screen went black during booting. I let it sit for several minutes and then reset the machine. It did the same thing a second time. I powered off, unplugged my front panel USB card reader from it's socket on the motherboard and rebooted. It booted quickly and with no USB enumeration complaints.

If this bug is being ignored, it's fatal. I generally like Fedora, but I'd go to Ubuntu or OpenSuSE in a heartbeat if I thought that would fix the problem. Unfortunately, it appears to be an issue in the USB driver code, and all of the distributions will likely see the same thing. So we need someone to pay attention to the bug.

I get the same thing in Fedora and in Linux in general my card readers in both my desktop and my laptop no longer work. Yes, it sucks.

I have everything here plugged into power strips. I find that when I turn on the strip, which adds power to the box, if I don't wait for the box to settle in before booting, it will do this. But if I allow a few seconds or so, then boot, all is fine.- (this just started about 3 months ago or so.) So it COULD be your boot method that is triggering the "bug".

BTW: I also notice that my USB2 drives don't run up to the speed they should either. Wonder if that could be related?

Hi I was unable to install either Fed 13 & Ubuntu 10.04 from a Linux Format DVD.. Managed to install Debian 5 but had to enable S.M.A.R.T and usb legacy in the Bios to get a working install. I nowl get this message, I presume I this was why I had trouble installing Fed 13 & ubuntu 10.04 Was running Fed 11 OK but over time getting the updates started causing frequent lock ups entailing a reboot This is still happening. The usb device concerned is the keyboard and I still have this problem and it seems to be initiated by a ubs mouse click before a page is fully loaded I read some where that it is probably a timing problem. Is there any fix for this?

What beats me is the fact that even after passage of a good length of time, the community appears to have no solution for this annoying and irritating bug.

In my case, my Lovelock (64 bit) worked like a charm before I 'yum updated' the system.

Now instead of opening to the beautiful login session of GNOME3, what I get is this extremely disappointing and irritating message of 'unable to enumerate .....'. The message just keeps printing itself incessantly scrolling down to infinity until I reboot with a ctrl + alt + delete.

Mind that this has happened to me after I have reinstalled Locklock after getting hopelessly fade up with the same phenomenon previously. I was wary of updating the system for almost a month. But finally being hopeful that the problem might have been resolved after so long a time, I dared going for an update and DARN!

I mean, 'What the heck is this?'

In MY case, I found out that that machine ended up having a DMA controller failure. It has since been replaced with a brand new build. Not sure if the two are related, (& in MY case, I don't care) but it may be worth a hardware check if nothing more than to rule it out. If you haven't somehow ruled out HW already. (didn't re-read the entire thread)

The problem is with the ehci_hcd subsystem - see the following:

Well, seems like I've found the root cause of my problem at last (and happy with the solution too!!!) In my case the cause was the cursed nVidia drivers that I had installed previous to the update. It appears that after an update, the kernel modules were also updated and that resulted in the constant "unable to enumerate usb device on port 5" blah blah blah. What did the trick for me is to completely remove nVidia drivers from my machine and (WHOA!) got my Fedora 15 to work like a boon. No more messages!!! After another update, the nouveau driver is doing a fine job of displaying the GNOME3 desktop.
