[ubuntu] usb storage devices not detected

[pac-man]

Hi, I'll describe how my problem happened:

First I was using xubuntu 7.10 and all the external storage devices were working properly (an external hard drive and a card reader). Then I decided to upgrade the distribution to 8.10 (surprisingly, it installed ubuntu, not xubuntu). The external storage devices work properly after the upgrade.

I had the system set up on 2 IDE hard disks, since I needed to remove one, I decided to do a clean installation of ubuntu (this time not xubuntu) 8.04, but to my surprise, now the external HDD nor the external card reader don't work at all!

Did a dmesg and the returned results are:

and the lsusb command show nothing but the mouse:

Bus 001 Device 001: ID 0000:0000

Can anyone help me? I depend a lot on my external drive and I don't really wanna go back to windows. I'm a bit disappointed with this 8.04 release, it looks like ubuntu reached its highest point on the 6.x releases and then it's a downwards spiral getting worse.

Thanks in advance!

I found a way to access the drive, I typed:

sudo modprobe -r ehci_hcd

But now whenever I plug the drive, it uses the ohci_hcd module, this uses the USB 1.1 speed on a port that used to use the USB 2.0 speed.

ANybody knows how to fix this?

If it works at low speed (ohci) but not at high speed - maybe your cable makes the problem. It could be a contact problem or too long or ...? Just try another cable...
