Re: ISP1761 and gadget or usbnet

Hi ,

The ISP1761 Host and Device Stack has been released for open source , 
which is tested working with 2.6.9 kernel on x86 PCI platform.
We are working to port same to latest kernel 2.6.20 , very soon I'll 
upload the Host Stack to sourceforge, Device Stack yet to start porting.

The Device stack may be different from the Gadget stack.

Regards,
Prabhakar Kalasani

Legal issues are news to me. There is an isp1761 open source project where 

you can get the code, but I believe the code there is much older than code 

we got direct from philips around last october.

Regarding usbnet we need it to work in device mode. I worked on IPAQs a 
couple years ago that did this correctly: you plug the unit into a pc via 
USB and you get an ethernet style link to the IPAQ linux os. I'm trying to 

do the same in our product which as far as I know involves cdc_ethernet 
and 
the gadget framework.

It's pretty frustrating, actually, since I have working bulk endpoints and 

all I need to do is get the ethernet frame in one end and out the other. 
Maybe someone knows how to get a usb network interface without gadgets?
