I am trying out manjaro KDE.
I m having a wierd USB issue where my Fiio DAC keeps on disconnecting every now and then.
dmesg gives following output
can you tell me a way to debug/fix this

It could be a motherboard issue where usb chipset drivers arent supported by manjaro but my other devices are fine, only audio device keeps switching. MacOSX and Windows run fine with the DAC I mentioned.
