USB keyboard and mouse not working on overo

[John Rigby]

Reported by Joey Stanford. UBS keyboard and mouse don't work on overo. This works on beagle so there must be some board specific problem.

On Headless:

I get an enumerate error when a keyboard is plugged in.

Jan 21 23:10:47 localhost kernel: [ 4860.508209] hub 1-0:1.0: unable to enumerate USB device on port 2

I don't get any errors when I plug in a mouse but the mouse doesn't light up.

I'm installing Netbook now to retest there.

USB is connected to the large USB port on the summit expansion board.

additionally, this error appears in syslog

Jan 21 23:15:13 localhost udevd[206]: specified user 'usbmux' unknown

My keyboard doesn't work either on a headless image. However, I have a different message. dmesg throws out:
 [ 56.703613] hub 1-0:1.0: unable to enumerate USB device on port 2

[Joey Stanford (joey)]

my comment in #2 is wrong. The serial console says

"Recognized Tobi expansion board (rev 0 R2783)"

We're also using the Overo Tide with this.

I bricked the system with my testing so once I reinstall I'll get an apport dump posted up here.

FYI:
1) I just upgraded to the latest kernel (2.6.37-1002-linaro-omap) and see the same thing.
2) I only get the "enumerate" error message *once*. When I pull the usb key and plug it back in, the kernel says nothing.

I built my own kernel with CONFIG_USB_DEBUG=y. Here's dmesg output when I plug my keyboard in:

Joey - I think this may not be a bug. According to Overo documentation:
  http://www.gumstix.net/images/overo_snapshot_19.pdf

You must connect your USB keyboard/mouse via a *powered* USB hub.

I did this and got the keyboard mostly working. ie - it only works if its plugged in at start-up. It doesn't seem to enumerate if you plug in the keyboard once the system is up.

NOTE: I don't have the DVI display working so I couldn't really check much on the keyboard. I just typed "return" twice and then typed the "reboot" command and the system rebooted.

Oh thanks! I'll give it a try.

I assume that Andy's finding was correct. Marking invalid.
