Title:
[USB-Audio - Scarlett 2i2 USB, playback] fails after a while
Apologies, I went on vacation for a few days. I've had the same results
no matter where I plug it in, but it seems to happen less frequently on
my powered USB hub, and MUCH more frequently when connected to a plain
USB 2.0 port (labeled for keyboard and mouse usage on the back of the
mobo). It stil
There's are two USB Controller, can you please connect to another one?
If it's connected to another USB Controller, you'll see it's under Bus 3
instead of Bus 1.

I booted into Ubuntu 18.04 with a 4.15 kernel and had similar issues. It
has been running steady for several days now off the powered USB hub
though so I'm pretty satisfied.
It doesn't seem like that change is relevant to this issue, although
seeing as this particular interface is somewhat common
Which kernel version was tested? I wonder if this helps:

After some testing on older kernels I was indeed able to recreate these
issues. The only thing I can think of is that somehow the hardware has
partially degraded such that it causes some issues with however the
drivers are implemented in linux but not in windows. I think it may have
something to do
Well, test an old kernel and we can know if it's a regression.

Unfortunately it seems to still be producing the same issue as before on
the latest kernel. Is it possible for this to be hardware failure? It
doesn't make a whole lot of sense as the issue persist even when
reconnecting the device and it works fine with a reboot. I've also
noticed that it most com
Okay, I have updated to the latest mainline kernel. If it manages to
hold steady the next few days I'll go ahead and close this issue.

I believe this is to be expected. I unplugged the device at this point
to show that plugging it back in does not fix the problem. If you keep
going down you will see it flounder when I attempt to reconnect the

However, if it really worked on previous Ubuntu release and older

I have added these parameters and by way of luck the issue happened soon
after rebooting. I attached the last 16MB of syslog (as the whole thing
was several GB by this point).
I also had some luck with hooking it to my powered USB 3.0 hub instead
of the 2.0 port on my motherboard, however I didn't
forgot to add, after the issue occurred, I unplugged and replugged the
usb audio interface and as expected it did not power back on. This
