[9fans] USB Network

[gnufan42 via 9fans]

Hello 9Fans,

I'm trying to get network working on a spare laptop. The laptop in question is relatively new, and has no extra PCI or PCIe slots, so I'll have to find a USB network adapter (I have an AX88772B, but that isn't recognized. In fact, the only thing I tried that worked was an Android phone with tethering turned on).

Can anyone recommend one (can be either Ethernet or 802.11) that works for Plan 9?

Thanks,
4d5a9000

I just tried out my USB C wired ethernet adaptor in 9front with
partial success.

I don't know how to report hardware info from 9front, but here is
what OpenBSD dmesg says about my adaptor:

        axen0 at uhub0 port 13 configuration 1 interface 0 "ASIX Elec. Corp. AX88179" rev 3.00/1.00 addr 4
        axen0: AX88179, address 00:90:9e:9d:0f:34
        rgephy0 at axen0 phy 3: RTL8169S/8110S/8211, rev. 5

It is automatically detected by 9front's install/live ISO; after
plugging in, I just run ip/ipconfig.

It seems to work for a while (once for less than a minute, once for
a few minutes), and then I see "usbreadproc: USB Transaction Error"
printed to the console, and it stops working until I unplug, plug,
ip/ipconfig again. I only tried ip/ping and briefly browsed 9fs
9front.

Let me know if further debugging would be useful to anyone. I do
not normally run Plan 9 on that laptop (but it's my only one with
USB C ports).

Hi James,

As for 9front, you can get the info of the adapter a number of
ways, `usbtree` is one such command. Would you mind sharing the
exact model of the adapter? And the usbtree output?

Best,
Aidan

Hi James,

I bought one USB Ethernet adapter with that chip, and it somewhat get recognized. On boot this showed up:

 nusb/ether: a179linkup: no link
 nusb/ether: a88179 init failed:

It seems that the one I got is defective. I tested the card on a Windows machine, and Windows also says "Network cable unplugged", although I'm sure I plugged the cable in, connected to a router.

Here's the result of usbtree:

 ep15.0: 255 csp 0x00ffff vid 0x0b95 did 0x1790 'ASIX Elec. Corp.' AX88179 118ae xhci

I'll try to get another one and see if that works.

Thanks,
4d5a9000

I think I saw similar messages when I first plugged it in on Friday.
I don't remember whether I needed to unplug/replug between those
messages and the first time I saw it working. Today when I tried
it again, I did not see those messages. And the messages I saw when
it stopped working were different.

        usbreadproc: Stopped
        usbreadproc: device is detached

Here's my usbtree output. The second-last field is different; I don't know how significant that is.

ep7.0: 255 csp 0x00ffff vid 0x0b95 did 0x1790 'ASIX Elec. Corp.' AX88179 e3ece xhci

As for the exact model: the brand is "TechKey" but I couldn't find anything that looks like a model number.
If it helps, the Amazon product page is at https://www.amazon.ca/dp/B07XLLTL7V and the description there is "USB C to Ethernet Adapter, Techkey USB Thunderbolt 3 / Type C to RJ45 Gigabit Ethernet LAN Network Adapter Compatible for MacBook Pro 2019/2018/2017 Dell XPS ChromeBook Galaxy S9/S8 and More".

(Sorry, 9fans, for all the emails)

4d5a9000,

Regarding your card..  this has happened occasionally, I find that
replugging the adapter itself usually does the trick, with the
addition that on my desktop, the first ethernet card (ether0) takes
precedence, so I will have to get an ip for the usb adapter
specifically:

        ip/ipconfig ether /net/etherUxxxxx

(Assuming it's not actually a defective chip)

Best,
Aidan

[gnufan42 via 9fans]

Hi Aidan,

It took a few days, but I got another AX88179 card. Yes, I confirmed that the old one is defective. The new one worked like a charm :-)

This card is pretty stable for me. I left Plan 9 with it running for a day and didn't see the USB Transaction Error.

Thanks,
4d5a9000
