Description Kyle Taylor 2024-05-14 21:47:20 UTC 
Hey All - 

Having issues with the last few builds of CURRENT on my Framework 13 laptop. Most of the builds have been working quite well (including the latest iwlwifi driver). But I'm having this issue with the wired ethernet usb expansion card that Framework ships. It only periodically works. It doesn't look like the if_cdce module has changed in about 9 months, so at-a-loss as to what's causing ue0 to be unavailable. Anyone else experiencing this with this card?

Comment 1 Li-Wen Hsu freebsd_committer freebsd_triage 2024-05-15 02:37:59 UTC 
I also tested some 8156 (and 8156B) USB dangles (but not Framework's), one of them also has this kind of issue. After some cross check, I highly suspect that it's specified due to the hardware issue of that one. Cause it has the same symptom on all my machines and the working ones are also good on all the machines.

Another thing, but not really related to this is that 8156 is actually supported with ure(4), with minor patch: https://reviews.freebsd.org/D45088

BTW, in your usbconfig output, the 0.2 and 1.2 is shown as "SMI Corporation USB DISK"?

Sorry, end-of-the-day post. That's a SD card reader. The usbus0 is what the ethernet card is attached to:

Comment 3 Kyle Taylor 2024-05-15 15:09:45 UTC 
After leaving it powered-off for the night and booting up the latest kernel build (yesterday), it works just fine. Maybe it only happens if you leave the machine booted and the card running for a few days? The card gets too hot or the bus gets tired.

I'm not sure and I somehow still feel this is hardware issue. In the mean time, if possible, please help me to test that patch so we can use more proper driver for 8156. It still needs some fixes but should be fine to test.

But it only works if I cold reboot the system and start without the USB-C charger attached. I can then plug the charger in after booting and it works just fine. If I boot the kernel with the charger attached, I get nothing.
Comment 7 Warner Losh freebsd_committer freebsd_triage 2024-05-16 03:15:06 UTC 
Can you add
hw.bus.devctl_nomatch_enabled=1
to /boot/loader.conf

and see if the problem goes away?
Comment 8 Kyle Taylor 2024-05-16 15:09:53 UTC 
(In reply to Warner Losh from comment #7)

Hi Warner - Didn't do it for me. The machine will boot but the ue0 interface never shows up after boot. There's nothing informative in dmesg when booting with verbose messaging enabled, either.

It still only sporadically shows up after boot when using the if_ure module that Li-Wen Hsu is testing. Card just seems glitchy. Like, when I use if_ure for a few hours, my switch will stop working for all machines connected until I physically disconnect my framework from the switch. This wasn't happening with the if_cdce module. It would still only periodically show up after boot, but at least the switch would still work.
Comment 9 Kyle Taylor 2024-05-16 15:39:55 UTC 
(In reply to Kyle Taylor from comment #8)

TBH, I don't think this is FreeBSD issue. This appears to be a Framework issue. This same behavior is reported by Linux users as well on their community forums : 

https://community.frame.work/t/responded-expansion-cards-and-usb-devices-cant-be-detected-and-disable-usb-ports-under-windows-and-linux/30697
Comment 10 ykla 2024-07-05 05:53:13 UTC 
I tested this bug by using an RTL8156B USB NIC on a Raspberry Pi 5 for nearly 24 hours. I didn't find any faults. The RTL8156B or RTL8156 had issues with disconnection in the past, but it seems that this problem no longer occurs. The AX88179A also had this issue ( https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267514 ), but it seems to be fixed. The driver hasn't changed, so the fix might be due to other kernel modifications or an x86 issue. I don't have an x86 platform to test on, but the AX88179A and RTL8156B work normally on the Raspberry Pi 5.
