ethernet gadget problem

hi people,
i'm new to the list, i hope someone could help me: i'm using a pxa270 cpu
over mainstone II like platform with linux kernel 2.6.18; i've read a lot
of messagges about this issue but i cannot find the solution: my target is
to use the ethernet gadget client interface (pxa270 side), but i found some
troubles; i discovered that to insert the module g_ether.ko (also in client
mode) i must previously install the modules usbcore.ko and dummy_hcd.ko is
this correct ?
here is the output when inserting all that modules:

[root@Linux /]#insmod usbcore
Using /lib/modules/2.6.18/kernel/drivers/usb/core/usbcore.ko
usbcore: registered new driver usbfs
usbcore: registered new driver hub
[root@Linux /]#insmod dummy_hcd

usb 1-1: 100mA is over 8mA budget for port 1!
hub 1-0:1.0: 92mA over power budget!
[root@Linux /]#

, after that, i can see the interface usb0 if run 'ifconfig -a':

[root@Linux /]#ifconfig -a
...
usb0      Link encap:Ethernet  HWaddr A2:BF:83:07:5E:46
          BROADCAST MULTICAST  MTU:1500  Metric:1

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

, but the host pc (x86 with 2.6.15-1-486) doesn't seem to see the target:
if i run dmesg into the host pc i can see:

usb 2-2: new full speed USB device using uhci_hcd and address 2
usb 2-2: device descriptor read/64, error -110
usb 2-2: device descriptor read/64, error -110

usb 2-2: new full speed USB device using uhci_hcd and address 4
usb 2-2: device descriptor read/8, error -110
usb 2-2: device descriptor read/8, error -110
......

, and so on;

is this a known issue ? where can i find solution ?
thanks in advance dylan
