USB Ethernet Adapters

I’m looking to get a usb ethernet adapter to try etherusb on my iyonix. Does anyone know if I would be able to choose between the motherboard NIC and the usb adapter in ‘Network’ Configuration. If not how would I chose to use the usb adapter instead of the Motherboard NIC?

Thanks

I not have a Iyonix :-( But I mean it work at the same way as an the Beagle. You need a activ EtherUSB and the autosense entrys. Configure network “USB to Ether” as primary interface, DHCP…
If I use my external Lindy on xM or RPi, RISC OS find the activ interface (LAN wire pluged internal or external works plug and play).
Maybe you find a better manual in the EtherUSB help or on James Peacock site.

Thanks Raik that got it working.

I had 2 problems first The autosense folder already had a EtherUSB file in it but it must have been for an older version of EtherUSB because it didn’t work. Found the latest version in CVS and that fixed that. The other problem was I wanted to keep my EtherK settings so didn’t want to untick the motherboard interface but unfortunately having both configured causes errors in !Boot.choices.internet.setup So I had to massage setup to get that to work.

Anybody interested, not sure, but I hope ;-)
I have two external USBtoEther adapter working with EtherUSB on Beagleboard, RPi A and Pandora.
But both not plug and play. Both are faster than the Lindy plug and play MCS7830 adapter.
I need a Obey in Predesk with the following lines (look at EtherUSB !ReadMe):
*Set EtherUSB$Product_VendorID_ProductID
e.g. for my first
*Set EtherUSB$Product_0b95_772a AX88772
and
*RMReinit EtherUSB
I found the IDs with USBInfo.

Is it possible to use two ethernet interfaces at the same time under RISC OS?

I wanted to connect my Pandaboard to a Asus wireless access point (and through my phone’s hotspot function to the internet) but also connect it to a PC using a USB-Ethernet adaptor, for cross-platform file sharing and editing. I don’t want the PC to be able to access the internet though, as it stops my tethering.

Originally, I planned to just connect the USB-ethernet adaptor to a spare USB port on the PC, bridge it to the built-in LAN and connect directly from the Pandaboard that way, but my phone doesn’t like me connecting through Windows and stops the data connection.

So, could I set a fixed IP on the PC of, say 192.168.1.10 and connect to a USB-Ethernet adaptor on the Panda with a fixed IP of 192.168.1.11, both with a netmask of 255.255.255.0? Then, use the built in Panda ethernet port to get a dynamic IP address from the Access Point. I’m assuming RISC OS won’t bridge the connections? Would this let me access files on the PC and yet still connect the Panda to the internet?

Have you tried it? You can set up two network cards at the same time.

That’s a start, that it can configure two interfaces! I shall get hold of a compatible USB-Ethernet adaptor and give it a go, then.

I have an unbranded AX88772 USB to Ethernet adapter which I am trying to use with a R-Pi compute module with no success. The VID is 0FE6 and the PID is 9700. I have added these parameters to the product table using this syntax:
Set EtherUSB$Product_0FE6_9700 AX88772

The device appears in the EJProducts listing but it is not consistent with the others set in the module.

+ 0FE6_9 9700 AX88772

What is the meaning of the “_9” suffix to the VID?

EJConfig gives “Bad Unit” error and the device is not recognised. What might be my problem please?

That is just a bug in the product list output. The ‘_9’ is from the product id in the system variable – it shouldn’t affect anything.

After setting the system variable you need to either rmreinit EtherUSB or unplug and reinsert the adapter. *showstat should show something if it is recognised and will also tell you if the device has a valid mac address. I have an ultracheap adapter which has a mac address of 00:00:00:00:00:01 which doesn’t work – it’s probably counterfeit.

It may be that it’s not a standard ax88772. What does *usbdevices show?

Well unless the logo on it says it is made by Xerox the MAC is invalid. A quick check on here will show you the manufacturer for any MAC, I just happen to know 00:00:00 is a Xerox prefix. Guess who drove the original MAC specification…

If you can set the MAC and you look up the Acorn allocation you should be on safe territory.

Interesting. In that case I suppose it is a valid MAC and should work – at least on a local network where there isn’t a device with the same MAC.

It may be that it’s not a standard ax88772. What does *usbdevices show?

*usbdevices for this item shows:
“SUNRISING QF9700 Ethernet”

After a bit of research, it seems that the 9700 chip (with various prefixes) is not compatible with the AX88772A chip. The device was bought on-line but the on-line photograph of the device does not match the device which I have received. The on-line photograph shows 88772A on the label. Can anyone confirm that the 9700 chip is a unique design and is not compatible with any of the chips supported by the RISC OS EtherUSB module.

Looks like the 9700 only does USB 1.1 (so 12mbit/sec max)?

If it isn’t what was pictured, can you send it back (or rate the vendor down at least)?

We found and Colin has confirmed that the 9700 is not ax88772 compatible and no RISC OS driver is available.
