![]() Thank you for your help! Edited Jby Prograde I am willing to try out just about anything, having two spare test unRaid servers currently going and hardware in hand. The last link is the most promising, and something I am looking to try out. I have found a few references looking about the web for both cards, and some recent information regarding the Startech PEXUSB3S44V and a possible custom kernel: This is where I think there should be hope for the StarTech card with unRAID/KVM with some discrete setting, or as seen in the last link below, a kernel supporting USB Attached SCSI.Īre there any 4 or more port USB PCI-e controllers other users have found to work properly with unRAID? Or even two port cards? This would add a whole lot of value to the platform, having a reliable way to pass USB controllers en masse to VMs. Ubuntu: Does not work at all, presumably due to same issue the windows VM was seeing.ĮSXI/Windows: Seems to work identically to the IFC-PCIE2U3, in that everything functions both in and outside the VMs and between shut-downs and reboots. #UNRAID USB 3 CARD DRIVER DRIVERS#Startech drivers and Microsoft xHCI drivers both do not work. #UNRAID USB 3 CARD DRIVER CODE#Windows: Throws a Code 10 error, device cannot start directly on hub. StarTech PEXUSB3S44V with four Renesas µPD720202 Controllers - Latest Firmware dated to 2012 Shutting down the VM and starting back up logs an error:ĮSXI/Windows: Same issue after clean shut down and cold boot with not handing controller back to the host/VM properly. Ubuntu: Works perfectly with native drivers on first boot. The port will not come back to functionality until the entire host is rebooted. Shutting down the VM and starting back up logs an error:ĭMAR: Request device fault addr ed000 PTE Read access is not set. Windows: HighPoint drivers do work OK, and all is well on first boot. Passes through to VMs OK, being seen in the OS. IOMMU Splits up OK with ACS Override and VFIO blacklisting. HighPoint RocketU 1144C with four Asmedia 1042A Controllers - Latest Firmware dated to 2014 Here are the two models I have tried so-far: I have found and tested a few devices that use a PLX chip to feed four separate USB controllers, and have had no success finding a reliable solution to work with unRAID. ![]() ![]() What I have been looking for is a quad-port four-controller USB (3.0 or 2.0, just want some I/O) PCI-e card that can be split into four different pass-through devices to use with four different VMs similar to how something like an Intel I350-T4 can be split up into four separate NICs each with a single port. Now you can imagine physical PCI-e ports can disappear quickly if you want to pass-through such native USB controllers to multiple VMs. I have had great success with both ESXI and unRAID passing through a USB controller to VMs using the Buffalo IFC-PCIE2U3, which is a simple dual port card powered by a single Renesas µPD720202 surface mount. ![]()
