  1. Deadron started following VM USB-Passthrough Issues
  2. Deadron
    Hello from germany, I have some issues with USB passthrough when using USB sticks, USB HDD and USB Bluetooth devices on my VMs. Mouse and keyboard seem to work just fine with some minor lag. When either the devices or USB controller are being passed through (OS doesn't matter if Linux of Windows) to the VM they are being properly recognized and installed. Unfortunately, when I'm trying to access those on VM installed USB devices, for example when I'm trying to copy something, the data transfer is getting slower and slower until the USB-Device completely disappears. After that USB device is no longer visible in Windows hardware manager too. Another example could be a headset, it's being recognized and installed too, but when I'm trying to use it the sound is delayed, or it stutters. Mice and Keyboards seems to work but when the host is overloaded, they stutter and react very sluggish/slow. When I'm on UNRAID-Host those problem doesn't appear, the Datatransfer is normal. The IOMMU groups are separated for example: IOMMU group 12: [1b21:2142] 01:00.0 USB controller: ASMedia Technology Inc. ASM2142 USB 3.1 Host Controller IOMMU group 13: [1b21:2142] 02:00.0 USB controller: ASMedia Technology Inc. ASM2142 USB 3.1 Host Controller What have I already tried: 1. New configuration of UNRAID 2. Different VMs and different OS (Windows, Linux) 3. Dedicated USB PCIe card 4. USB controller with vfio-pci.ids= impossible 5. Different USB controllers 6. USB hub with its own power supply My specs: Model: i9 7900x 32GB M/B: Micro-Star International Co., Ltd X299 TOMAHAWK (MS-7B05) Version 1.0 BIOS: American Megatrends Inc. Version 1.90. Dated: 07/31/2018 CPU: Intel® Core™ i9-7900X CPU @ 3.30GHz HVM: Enabled IOMMU: Enabled Cache: 0 KiB, 0 KiB, 0 KiB Memory: 64 GiB DDR4 (max. installable capacity 3072 GiB) GPU-Passthrough work without any issues, I have tried RTX 2080 or GTX 970, and other non-USB devices like TV-Cards or NIC-Cards work just fine. I've exhausted all ideas I could came up with, that’s why I need your help. Many thanks in advance.
