BF527 USB HOST + USB HUB

Hello

I use in the project bf527+uclinux.

I configure linux kernel ADI USB HOST controler.

At connection USB HUB to BF527, linux kernel sees a hub, But devices connected to a hub don't work.

 

in Hardware Reference:

 

Endpoint Setup and Data  Transfer

When the HOST_MODE bit is  set to 1, the USB cont roller operates as a host

for point-to-point  communications with another USB device. This second

device may be either a  high-speed, full-speed, or low-speed USB function,

but it may not be a hub.  Control, bulk, isochronous or interrupt transac-

tions are supported between  the USB  controller and the second device.

 

Here and a gift

 

How to bypass this restriction by a program way?
It is possible?
