Hello
Im not so sure if this is relevant or not but sometimes when installing
6.2.fs onto a usb stick it wont boot in one of the exterior front USB3
Ports, I pretty much dismissed this as an electrical connection issue
but maybe there is more to it ...Unfortunately I only use USB3 for
installing OpenBSD after that I dont really use it at all

Not sure if it will help or not, but I recall a timing issue on earlier
versions of FreeBSD and the APU2/3s where I could work around it by
loading the xhci module as a kld after the box had fully booted.

No :(, I worked on it for a while but kernel hacking isn't my
speciality. I don't think the specific quirks I was initially trying to
port would have fixed it anyway, as they seemed mainly aimed at data
transfers and I couldn't even get the miniPCI card to get hot plugged
and detected while testing with an external miniPCI to USB adapter
plugged into the internal EHCI header.

I ended up just using the external adapter plugged into the xHCI ports
exposed outside the case. Annoying not to be able to just have it inside
the case, but it works like a champ in this configuration.

Hi,

I have the same problem and have tried to hunt the bug, but failed so
far. Have you already identified the quirks linux and freebsd use to
fix this problem?

My APU3b4 has just arrived, hopefully I'll have time to install it with
OpenBSD tomorrow and send feedback.

Assuming you're planning to use an internal Mini PCI card, unless you have more 
luck than me, it's not going to work :(. I'm hoping I will be able to fix the 
EHCI driver to be more happy with the AMD USB chipset, but this point I'm still

I have a bunch of APU2c4's, they play nice with OpenBSD. Actually my
complete fleet (~20) of branch office routers are based on
APU2c4's running various OpenBSD versions (I think the oldest is 5.8).

I have just ordered one APU3b4, as I wanted to test mobile provider as
a backup link. I see it probably won't be any good as OpenBSD router
(yet), but at least I'll be able to test and give feedback.

I have a APU3b series, they fixed the incorrect pinout on the internal
usb headers. The internal ECHI ports work fine under both linux and
freebsd connected to a USB backplate I'm testing with. It's definitely a
disagreement between the AMD EHCI USB chipset and OpenBSD . I'm
going to see if I can port some of the workarounds and quirks for that
chipset from linux/freebsd to the openbsd driver and see if I have any
luck getting it working; drivers aren't my strong suite but we'll see
what happens. In the worst case I guess I'll use an external miniPCI to
USB adapter and connect my LTE modem to the external xHCI ports, they
seem to work fine under OpenBSD.

Thanks...

On the APU3a4 the internal USB headers were broken.
I had email from pcengines (March 2017) saying this would
be addressed in the APU3b series., but we went for APU2.

Have you asked pcengines if your internal USB
headers are fully functional?

Thanks for the feedback. Do you by any chance have any USB type Mini PCI cards 
installed internally? I initially noticed the issue with a mini PCI LTE modem 
card. Then I realized it was a more generic USB problem; I believe the apu2 has 
USB1 and USB2 ports, the apu3 has two USB3 ports externally, and then the mini 
PCI and a couple of internal headers are USB2. The USB3 ports, using the xHCI 
driver, work fine, I suppose in the worst case I could use an external Mini PCI 
to USB adapter and plug the card in outside of the case, but that just seems so 
kludgy .

I actually found a friend locally who had a apu2 board, he couldn't get the LTE 
card to work on the internal mini PCI slot, which also appeared to be EHCI 
based, and it would sometimes work and sometimes not plugged into the external 
USB ports. It was really weird, when plugged into the same external port, 
sometimes the device would show up on the EHCI bus (and not work) and sometimes 
it would show up on the OHCI bus (and work). He didn't seem to have any trouble 
with USB flash drives on the EHCI bus on his apu2 though.

No problems here running on APU and APU2 boards, or their USB ports for

I too have not yet seen or tried an APU3.
