Hey y'all, I've got 3 devices fighting for IRQ priority I think. Of course I'd like my 2i2 interface to have this highest but sometimes at boot, one out of the 3 doesn't get a connection. For instance, if I start Jack then try to mount the USB storage devices, they take forever to mount or fail. Other times I'd start Jack and it would fail. I'd have to unplug the 2i2 then plug it back in, start Jack and I have sound. From there, I'd lose one of the USB storage device.

Is there a way to assign IRQs to each? I'm on Arch64.. Any configuration that can fix this?

Can you check which ports are usb 1,2 or 3? There may be more than 1 controller chip.
My usb 3 ports are on an NEC controller, the hardware connectors commonly have
blue plastic in the inputs, and some devices may have issues with usb3

My usb2 ports are on an Intel controller. I have one usb3 external drive
in a blue connector, and often boot an external-drive Mint17
from a usb2 port. My usb Mustang amp is choosy, It likes to be on at boot,
then start qjackctl, then launch it's Plug editor app, and hates being unplugged
from active usb, whether at work, or taking a coffee break.
I also have usb mouse/keyboard, which don't appear to care about being pulled.
I'd bet there is a combo that will work for you,
maybe even a powered usb hub, to isolate either your soundcard,
or all the other stuff, from any conflict.

commands providing usefull info:

procinfo
inxi -F
lspci
lsdev
lsusb
cat /proc/intterrupts

Good luck!
