I did an upgrade from 8.10 to 9.4. USB flash drives dont mount any more. Or any USB mass storage for that matter.

[10369.956066] usb 1-3: new high speed USB device using ehci_hcd and address 6
[10370.089554] usb 1-3: configuration #1 chosen from 1 choice
donp@sparky:~$

lsusb shows the device, but ubuntu does not do anything else.

I have the same problem, I tried everything but still can't mount my pendrive.

Same problem here.

When I plug in my LaCie external hard drive, nothing happens.

dmesg just gives

[ 438.256095] usb 1-7: new high speed USB device using ehci_hcd and address 3
[ 438.389310] usb 1-7: configuration #1 chosen from 1 choice

and the device does not appear in "fdisk -l"

I'm using Ubuntu 9.04. In 8.10 it worked well.

On my brother's laptop with 9.04 it also works well!
"dmesg" on my brother's laptop gives:

Apparently my Ubuntu doesn't even recognize that the thing I plugged in is a mass storage device?

Any ideas?

I think is a problem with usb 1.1 devices. I have read a thread that say the problem is solved disabling the echi_hcd module. But since now is part of the kernel, can't be disabled. Can be like that?

My pendrive is listed in 'lsusb' but not in 'fdisk -l' nor '/proc/partitions'.

If somebody knows how to solve this issue, please answer.
