Subject: [U-Boot] EHCI hub not powering on port

Hi all,
I am trying to make u-boot work with my EHCI controler and everything goes well up to when it comes to powering on the port:

According to the USB 2.0 specification paragraph 11.11, this is the correct behavior since both HUB_STATUS_LOCAL_POWER in wHubStatus and
HUB_CHANGE_LOCAL_POWER in wHubChange are set. Issuing a port power feature to the port would have no effect.
Has anyone already met similar problems with EHCI hubs integrated to EHCI controllers ?
Thank you very much in advance.
