If you run it as "usb -v", then the userspace code should tell you what it's doing when you do things like connect to the USB host. > Also, is it valid to use the same vendor number, product number > (NetChip) which are found in usb.c when I am using omap or should I use a > different vendor number, product number, etc? What matters is that that vendor and product code pair not be misused with a protocol-incompatible userspace driver. If you have a vendor code of your own to supply, you could do that (using your own product number registry), but it's not essential. - Dave > Thanks! > Lizette > > >From: David Brownell <[EMAIL PROTECTED]> > >To: linux-usb-devel@lists.sourceforge.net > >CC: "zil iram" <[EMAIL PROTECTED]> > >Subject: Re: [linux-usb-devel] testing gadgetfs on omap > >Date: Thu, 24 Aug 2006 11:03:12 -0700 > > > >On Thursday 24 August 2006 3:17 am, zil iram wrote: > > > > > > Thank you very much Dave.
