Hello, everyone!

I have just compiled EHCI into kernel, but have no luck
on making USB2 working :(  Is USB2 supported or it is still
buggy on fbsd?

When I plug USB2 device kernel yields:

 uhub3: port 1, set config at addr 2 failed
 uhub3: device problem, disabling port 1
 uhub3: port 5, set config at addr 2 failed
 uhub3: device problem, disabling port 5

I'm running 5.2-current (13-Jun)
Any ideas will be appreciated!

Cheers,
           AL.
