z97 and USB Audio Interface

[doubletheman]

Im using RME UFX when i upgrade to Z9X7 ud7 th the USB connection got many problems...
on z97 will show some pop and cracker sound even random disconnect...
but now I change to Firewire seem no problem...
but I wanna find out the problem and back to USB
because the sound on usb better


my last build is z87x ud7 th has no any problem here...


I has tried everything I known even reinstall os

There some trick i have to try
1. disable XHCI on the bios will force to USB 2 (but no help)
2. use PCIe NIC USB card ( still no luck )
3. use some xHC kernel flag ( no luck )

hope any one use Z97 Series mobo can give some feedback!!!!!!



when the pop sound show up my digicheck will like this....

Try BIOS settings
XHCI Mode Auto
XHCI Hand-Off Enabled
EHCI Hand-Off Enabled

No problem here with Z97X-UD3H and Roland Quad-Capture alone on the USB2 ports. All my other USB devices are connected on USB3. Rock solid as low as 48 samples.
