Hi,
It looks like I've got most thing implemented regarding USB CDC for the
Sam9g45. I do however have some basic questions.
One of the things is that I don't see any descriptors in Windows. I installed
some inf file found on the net for Ethernet RNDIS but maybe that was wrong.
Is there any Windows driver available for the Linux CDC interface ?
Second I connected the device to my Linux host and dmesg says looks a bit
better :
usb 1-4: USB disconnect, address 39
usb 1-4: new high speed USB device using ehci_hcd and address 40
usb 1-4: New USB device found, idVendor=0525, idProduct=a4a1
usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-4: Product: Ethernet Gadget
usb 1-4: Manufacturer: Atmel AT91SAM9G45
usb 1-4: configuration #1 chosen from 1 choice
lusb output is shown below. I see the following line :
iMacAddress 3 (??)
Is this normal or did I perhaps miss something crucial here ?
One thing I notice is that things are rather slow in Linux and probably also
the reason why things don't work in windows yet. It takes a couple of seconds
for lsusb to show information and my guess is that still something is wrong.
Best regards,
Marcel

Hi,
Never mind, I overlooked the string descriptors.
The funny thing is that the Linux host just continues where the windows host
simply stops communicating with the device.

Marcel

RNDIS is not supported in U-boot.

This driver works reliable in our situation combined with the
CDC-layer of U-boot:
