Hi All,
While testing the linux ethernet gadget using windows xp SP2, PC sometimes
does not recognize this mobile handset as the USB device.
Unknown device
( expect "Linux USBEthernet/RNDIS gadget")
Is this the problem with USB enumerator driver (usbccgp.sys) or the Device
side problem?
Thanks ~Jithendran

Hi All,
We are developing a VoIP enabled WiFI mobile handset using PXA255 running
Linux 2.6.10.We have enabled the RNDIS gadget in the kernel for the
Ethernet over USB functionality
When the handset is connected to the USB port of Windows XP host, the USB
peripheral will enumerate to the host as an Ethernet device . Using Start
Menu->Connect To->Show all connections We Find the entry containing the
Device Name of "Linux USB Ethernet/RNDIS Gadget". Rename "Local Area
Connection 3" .
However the network connectivity is lost frequently with the message
"UDC:USB Reset" in the device side when VoIP activity is happening or the
host is used for browsing internet.
We are using the standard RNDIS drivers bundled with the XP distribution.
Thanks,
Jithendran

This error is a device side error. I would bet when it enumerates as an
unknown device, it’s hardware ID is usb\vid0000&pid0000. this means the
host controller could not enumerate the device. By the time usbggcp
get’s into the picture, the OS must have been able to get the vid/pid
and determine that the device has multiple interfaces.
