Hello,

I've recently buy a new TFT screen : Dell UltraSharp 1704FPT which
have a USB Hub (4 ports) in it
(http://accessories.us.dell.com/sna/ProductDetail.aspx?sku=320-3952&c=us&l=en&cs=19&category_id=210&first=true&page=productlisting.aspx).

When I plug USB between the screen and my motherboard. I get theses
messages in dmesg (with USB debug) with 2.6.11.9:

I've made a lot of search on google about theses errors and didn't
find anything.
I've include my .config in attachment.

I _think_ it's not a configuration problem but maybe a kernel one or a
hardware one.

I don't have Windows to test it so :/

What can I do for that ? I know C code (never made a kernel hack).

Thanks
