One has to remember that USB is just the bus just like pci, microchannel, etc. Even though you have access to the device on the bus you still need a driver for that specific ethernet chip your kernel. This is analogous to having a video card on the pci bus, you still need for the kernel to drive the specific chipset of the card regardless if it can see it on the bus. I have an HTC Nexus One so I may fiddle with this and see if I can help some more here. I am wishful that at least we can get a tty just like other gsm modems and from there it's pretty straight forward using wvdial or alike. If it's only the Ethernet over usb like you mention, then the chipset driver would have to be translated/ported to the FBSD kernel, if it's not already there ? Ok. But I will clarify here: The HTC Android systems uses an "Internet Sharing" feature- essentially Google has coded in routing/nat system into the base OS (probably moding the leftover code already in the linux base), and is trying to allow similar using bluetooth and wifi at a later date as well. The RNDIS is a M$ system that allows sharing anything over USB (network, files, etc- but all essentially operated as network anyway), something they've been playing with for some years- I was looking for an A-A USB cable since around 2003 or so to quickly transfer files when needed. Apparently M$ opened the specs a year or two ago and everyone's jumped on to use it. So where Google started was to start allowing the use of the router/nat via RNDIS USB - somehow this was easier than allowing bluetooth or wifi (probably security and available hardware features). So yes, apparently the phone hooks up as a usb mass storage device, uploads a file to the computer, and disconnects and becomes a network device. Here is the output from linux: usb 2-2.2: new high speed USB device using ehci_hcd and address 4 usb 2-2.2: configuration #1 chosen from 1 choice scsi9 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 4 usb-storage: waiting for device to settle before scanning usb 2-2.2: New USB device found, idVendor=0bb4, idProduct=0ff9 usb 2-2.2: New USB device strings: Mfr=3, Product=2, SerialNumber=1 usb 2-2.2: Product: Android Phone usb 2-2.2: Manufacturer: HTC usb 2-2.2: SerialNumber: SH07TNX00726 usb-storage: device scan complete scsi 9:0:0:0: Direct-Access HTC Android Phone 0100 PQ: 0 ANSI: 2 sd 9:0:0:0: [sdf] Attached SCSI removable disk sd 9:0:0:0: Attached scsi generic sg6 type 0 usb 2-2.2: USB disconnect, address 4 usb 2-2.2: new high speed USB device using ehci_hcd and address 5 usb 2-2.2: configuration #1 chosen from 1 choice usb 2-2.2: New USB device found, idVendor=0bb4, idProduct=0ffe usb 2-2.2: New USB device strings: Mfr=3, Product=2, SerialNumber=1 usb 2-2.2: Product: Android Phone usb 2-2.2: Manufacturer: HTC usb 2-2.2: SerialNumber: SH07TNX00726 usbcore: registered new interface driver cdc_ether usb0: register 'rndis_host' at usb-0000:00:04.1-2.2, RNDIS device, ae:f6:3d:da:20:39 usbcore: registered new interface driver rndis_host usbcore: registered new interface driver rndis_wlan usb0: no IPv6 routers present usb 2-2.2: USB disconnect, address 5 usb0: unregister 'rndis_host' usb-0000:00:04.1-2.2, RNDIS device So. What would be my next step to make this work? OpenMoko have something similar and I tried moding some of their scripts (they've made theirs work with ALL OS- not just linux and Winblow$! Take heed manufacturers!) but it didn't mesh on the Android. I still end up with a generic host. As I mentioned, I tried modifying the cdce driver and the device list but that didn't help either, so when I moded the scripts and devd.conf I figured that was the missing piece of my puzzle. I'd actually pay someone to do this, but I do need to figure this out for myself anyway so I'm diving in deep and going to keep on struggling till I get it. I need it figured out before the year's end so I'm not going to sit on my laurels :) That, and a usb mass storage device emulator to trick a dumb digital photo frame.... > > So I have more on this: sourceforge.jp has a project rndis for freebsd. Its a little hard to navigate, but I downloaded the source code and tried to build it on 8.0. No go, but I'm not sure what usb library its using. I think it said usb2, but I'm not exactly sure what that meant (usb2.0, or libusb2, whatever). Now, I've only just quickly grabbed it and tried to make- I haven't had a chance to look too deeply into it as yet- but these are the errors if someone could throw me a clue as to what it might be indicating? (wrong library? generic error I have to debug?) if_rndis.c: In function 'rndis_recv_message': if_rndis.c:985: warning: format '%d' expects type 'int', but argument 3 has type 'long unsigned int' if_rndis.c: In function 'rndis_bulk_read_callback': if_rndis.c:1167: warning: format '%d' expects type 'int', but argument 4 has type 'long unsigned int' if_rndis.c:1187: warning: format '%d' expects type 'int', but argument 4 has type 'long unsigned int' if_rndis.c:1204: warning: format '%d' expects type 'int', but argument 4 has type 'long unsigned int' *** Error code 1 I did get from the site that it was for Windows Mobile, but I believe that this is a generic system coming out now. It might help?
