Re: [Gumstix-users] USB Host port on Toby and Overo Earth

[kailoi <chr...@gm...>]

Ok.. sorry for the sudden followup. I tell a complete lie. I am seeing
something in dmesg: 

ehci-omap ehci-omap.0: GetStatus port 2 status 001402 POWER sig=k CSC

over and over and over

if I do a lsusb I get 

root@overo:/home/ubuntu# lsusb
hub 2-0:1.0: unable to enumerate USB device on port 2

hub 2-0:1.0: unable to enumerate USB device on port 2
hub 2-0:1.0: unable to enumerate USB device on port 2
hub 2-0:1.0: unable to enumerate USB device on port 2

and this goes on until I reboot it. Suggestions?
