Newest kernel on Precise or Saucy causes USB to take 5-min to mount

[vmc]

Using mainline kernels I installed kernel-3.2.37-030237-generic, and the problem was resolved.
Using kernel-3.8.0-28-generic on either Precise or Saucy and mounting any USB flash stick takes 5-6 minutes to mount.

SYSLOG example:

"Aug 2 09:04:10 u kernel: [ 168.632651] usb 1-8: new high-speed USB device number 8 using ehci-pci"

Right after last message, the USB was mounted

I'm seeing this bug from various distros now, not just Ubuntu. I tried reporting to kernel.org, and have just received to responses.
I have since installed kernel-3.5.0.38. Its the last one that works, which is from quantel The raring kernel-3.8.0.28, is the one that breaks USB.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I found the solution to this problem. There's a patch out from
http://www.spinics.net/lists/stable/msg16448.html :

Hopefully it gets out to Ubuntu's kernels soon.

The latest Saucy build has the kernel fix installed:

linux-image-3.11.0-999-generic_3.11.0-999.201308150422

I installed it in my Ubuntu 12.04 Precise and it too now works.

[Mark Fraser (launchpad-mfraz)]

I can confirm this bug in linux-image-3.8.0-29 as installed in Raring with a Sony Hi-MD recorder, but sometimes it still won't mount even after 5 minutes.

[Mark Fraser (launchpad-mfraz)]

This is now fixed in the latest kernel for 13.04.

[Brian Burch (brian-pingtoo)]

Agreed. Working nicely again under 3.8.0-30-generic.

Not sure if it is relevant, but I noticed earlier releases that were taking a long time to mount my camera and several usb sticks were able to mount the file system properly for my android 4 phone. I had given up trying to get this feature to work last year, and got into the habit of using adb to transfer files. I was pleasantly surprised to see android working, although this coincided with the annoying 10 minute mounts for devices that had worked fine for ever!

One of the suspicious syslog messages was "mtp-probe: bus: 1, device: 2 was not an MTP device", but that message still appears on the new kernel. I wonder whether fixing android usb originally broke mounting of older device types?
