Problems with USB Gadget driver when host is windows


Hello..

We have a device with both USB host and device ports.Runs on Ubuntu 9.04.The gadget driver (g_printer) is present on the device.From a host Linux PC(with Generic printer driver installed) we are able to write and read through /dev/usblp0.The data send by Linux Host PC is received by device.But the same device,when it is connected to a Windows PC (XP) with printer driver,the data send by the host is not received by the device.When we connect a USB Analyzer,data send by the Windows host PC is visible but there are no acknowledgments seen.What could be the reason for this ?

Thanks.
