When i changed to Windows 10 64bit nothing but problems, occasionally recognized, more often not. Legacy drivers wouldn't work either, and i had to use USB. I was told a Texas Instruments PCIe card with both 1394a AND b (Firewire 800) should work, but these cards usually cost around $40. I then decided to exchange my UFX for an UFX ii, which works OK with windows 10, BUT not quite well with the motherboards' ASMedia USB chips. A PCIe USB 3.0 card i had with NEC (Renessas today) chips does.

        UPDATE: after quite a while i had dropouts again, and shortly after they turned into the pulsating distorted sound i had before. After removing and  reinstalling all my PCs' USB drivers for the present hardware, BOTH ASmedia Root USB hub, and ASmedia USB 3.1 eXtensible Host Controller drivers, it worked again. The UFX ii however still was connected to another PCIe USB 3.0 port with a NEC chip (Renesas eXtensible Host Controller USB 3.0).

        UPDATE 2: Updated my ATI graphics drivers, choosing the elementary version, removed Bitdefender 2017 Total security and it's firewall. Installed 360 TS and Zonealarm free ... and my problems now seem to be over. - F

Yes and a 1070 NV card. Tried disabling the ASIO guard. No luck.

Working on it. need to gather all the info. appreciate it.

Hi all, bumping this thread as it seems closest to my issue, as described by OP: audio stuttering, both WDM and ASIO, no way to recover other than switching RME hardware off and on again. Sometimes after 2 minutes, sometimes after 2 hours.

Lenovo P1 (not affected by Thunderbolt issues), UFX II, tried directly or via xcellon hub, either Thunderbolt or USB 3 connectors, issue keeps returning at what seems random points, the only correlated way to sometimes trigger it is by opening the Windows 10 search box by pressing the windows key.

Tried:
- Removing/reinstalling all drivers, including all USB devices
- Disable all USB related power management options
- Reinstalling all RME drivers and tools
- BIOS and graphics settings (including nvidia specific and minor ones like mouse trails)

Any and all pointers incredibly appreciated, really looking forward to get production going but this is incredibly frustrating... Thanks!

Thanks Matthias! Error is the dreaded Fifo Error after USB counting up.

I'll get deeper into Latency Mon (thanks for the recommendation!), right now most seems pretty tame in the light to darker greens, and haven't been able to trigger a stutter-on-search occurrence. Surprised that the EuControl driver is more draining than the Nvidia Quadro or storage. My current hunch is that between the GPU, the Thunderbolt Sandisk Pro and USB accessories the PCI bus itself might get exhausted.

EDIT, here the two Latency Monitor lists pre-crash:

Is there any magic RME could work to recover more gracefully? Brief crackle and then back to normal without hardware reset needed?
