Dear all
I'll answer to myself, so maybe someone else that is working with this
device can find this email and get to the right solution sooner than I :-)
It seems that all the driver proposed to the "official" mailing list are
somehow buggy.
By looking inside the official Intel embedded mailing list (I cannot
post the link here because is a restricted mailing list, you have to
register to the Intel embedded design center (edc.intel.com) to access
to it), I've found a support thread with attached a driver that is newer
than all the one proposed for inclusion in the kernel and that solve all
problem that I had.
This driver support kernel version: 2.6.22.18, 2.6.24, 2.6.26, 2.6.27
Best Regards,
Andrea

Dear All,
we need to use Poulsbo USB device interface as CDC Ethernet device.
I've found on OSADL site
(http://www.osadl.org/Linux-on-Atom-Poulsbo.howto-linux-on-atom.0.html)
and in various kernel mailing list (e.g. here
http://thread.gmane.org/gmane.linux.usb.general/13773/focus=14847) that
there is a device driver, at least for an "old" 2.6.24 kernel.
I've successfully ported the kernel to our platform (a Kontron
nanoEXTexpress-SP based host board,
http://it.kontron.com/products/computeronmodules/com+express/com+express+ultra/nanoetxexpresssp.html)
without many problems.
However the driver is not working, due some errors that you may find in
the attached kernel dump.
On the host side, I see that the plug is correctly detected,
GET_DESCRIPTOR request is sent (and received by the device), but the
answer is not correctly sent back (I've seen, with wireshark, that the
USB packet is somehow corrupted). I'm not a USB guru so I don't really
know how to debug this.
BTW the hardware is working, I've tested the USB device interface with
WinXP ( :-( ) driver showing no problem at all.
Is anyone using Atom Z530/Poulsbo with USB device interface? If so, with
which kernel/driver?
Best Regards and Thanks in advance,
Andrea
