Since 2.6.16-rc1, when RNDIS devices are not configured; when a device
is attached, following messages are logged by kernel:

 usb 1-1: new full speed USB device using uhci_hcd and address 2
 usb 1-1: default language 0x0409
 usb 1-1: new device strings: Mfr=1, Product=2, SerialNumber=3
 usb 1-1: Product: Remote NDIS 802.11 Wireless Adapter
 usb 1-1: Manufacturer: Broadcom
 usb 1-1: SerialNumber: 000000000001
 usb 1-1: uevent
 usb 1-1: device is bus-powered
 usb 1-1: no configuration chosen from 1 choice

It seems to be due to a typo in a conditional (patch against 2.6.17-rc5):

This requires RNDIS host to be compiled into kernel itself - it won't
work if RNDIS is compiled as module. However, I have been using RNDIS
devices with ndiswrapper without RNDIS host; for this, following patch
works:
