[new-usb] - USB_ERR_NO_POWER on keyboard hub

[Renato Botelho]

I have a Sun USB Type 7 keyboard, and this keyboard has an USB hub
with 3 ports on it. I'm using one of those 3 ports to plug the mouse and
it's working fine.

uhub5: 4 ports with 3 removable, bus powered
ugen0.3: <Alcor Micro> at usbus0
ums0: <Alcor Micro USB Mouse, class 0/0, rev 1.10/51.27, addr 3> on usbus0
ums0: 3 buttons and [XYZ] coordinates ID=0
ugen0.4: <Sun Microsystems> at usbus0
ukbd0: <Sun Microsystems Type 7 USB keyboard, class 0/0, rev
2.00/1.04, addr 4> on usbus0
kbd2 at ukbd0

When I tried to plug a pen drive on anothe one, I got this:

usb2_set_config_index:531: power exceeded 500 > 100
usb2_set_config_index:531: power exceeded 500 > 100

I'm using FreeBSD 8.0-current r192140.

Let me know if there is more information i need to provide.

Thanks
