Dear All,

I have BeagleBoard OMAP 3450 Rev C3 board.

I tried installing Ubuntu 11.04 and Android 4.0.1 and in both cases, I always get the following error:

[ 3.191467] ehci-omap ehci-omap.0: USB 2.0 started, EHCI 1.00
[    3.192382] hub 1-0:1.0: USB hub found
[    3.192413] hub 1-0:1.0: 3 ports detected
[    3.222717] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
[    3.223388] mousedev: PS/2 mouse device common for all mice
hub 1-0:1.0: unable to enumerate USB device on port 2

hub 1-0:1.0: Cannot enable port 2. Maybe the USB cable is bad?
hub 1-0:1.0: Cannot enable port 2. Maybe the USB cable is bad?
ehci-omap ehci-omap.0: port 2 cannot be enabled
ehci-omap ehci-omap.0: Maybe your device is not a high speed device?
ehci-omap ehci-omap.0: USB host (EHCI) controller does not support full speed or low speed device on it’s root port.
ehci-omap ehci-omap.0: Please connect full/low speed device via a high speed hub. hub 1-0:1.0: unable to enumerate USB device on port 2

And because of this, I am unable to use usb-ethernet, usb-mouse or usb-keyboard :(

Please help.

Just to be sure, I must add that the usb-hub and all the devices connected to it gets immediately recognised when I plug it on my Laptop.

If this is a driver problem, is there anyway I can get the working version with all the patches for a particular kernel version?

Can you please provide me with the site for patches/fixes for particular kernel versions?

Please help!

Patrick

Please send the entire log and .config file. We need to make sure that you have EHCI HCD enabled in drivers->USb Support-> and Have high speed hub connected to EHCI port.

minicom_ubuntu11.04_omap.log

Thanks for replying. Please find attached my logs.

I have attached the .config files for the kernel of Android4.0.1 on OMAP3530 as well as for the kernel for Ubuntu 11.04

Additionally I have attached the minicom Logs during booting for both.

Please take a look and let me know what can be done.

Thanks.

config_ubnuntu_omap.txt has EHCI_HCD disabled.

# CONFIG_USB_EHCI_HCD is not set

You said you connected a high speed hub to beagle board EHCI port but it seems that hub is not getting detected and configured correctly.

1) Do you have other USB2.0 high speed hub to try?

2) Can you connect a high speed pen drive to EHCI port and see if that works?

Hello Ajay.

Thanks for your inputs. I have another USB 2.0 high speed externally powered HUB with which I tried.

It doesn't work either.

There seems to be something wrong with PHY. Did you run the second test I asked for? You can connect a high speed usb pendrive directly to the board and see if that work. Provide the log also for the same.

Here are the logs. I connected a USB 2.0 high speed pen drive.

Let me know if I have to reconfigure and recompile my kernel enabling some new CONFIGs.

I still see same error of "hub: can't enable port 2" and so host controller is not even started talking to high speed pendrive but before that it failed to enable port2 of root hub connected to USBHOST subsystem.

I am not sure if your kernel version needs some changes related to USB PHY reset or power. I will ask another person to look into this thread and respond.

Hi Ajay,

Thanks for your reply.

In the meanwhile let me know if I have to try changing some CONFIG parameters while building the kernel.

Cheers.

Your config looked fine to me. The issue seems to be mostly relates to some GPIO for EHCI power etc. I have asked another engineer to respond you.
