csmccarron Posted June 24, 2017 Share Posted June 24, 2017 (edited) Would it be possible to add a module for USB Attached SCSI (CONFIG_USB_UAS) protocol? This is required to support a card like the StarTech PEXUSB3S44V. There are a number of users trying to get this card working. The UnRaid kernel enumerates the card but it does not actually work. This card has 4 independant USB3 controllers and it looks as if you could pass each controller to a different virtual machine. UASP Information On this thread @Siberys details his issue with the StarTech PEXUSB3S44V USB3 card with 4 separate USB3 controllers that needs UASP support to function. 08:00.0 USB controller [0c03]: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller [1912:0015] (rev 02) (A) 09:00.0 USB controller [0c03]: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller [1912:0015] (rev 02) (B) 0a:00.0 USB controller [0c03]: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller [1912:0015] (rev 02) © 0b:00.0 USB controller [0c03]: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller [1912:0015] (rev 02) (D) /sys/kernel/iommu_groups/42/devices/0000:08:00.0 /sys/kernel/iommu_groups/43/devices/0000:09:00.0 /sys/kernel/iommu_groups/44/devices/0000:0a:00.0 /sys/kernel/iommu_groups/45/devices/0000:0b:00.0 Post 1 Post 2 UPDATE: I have built a unRaid 6.4 rc6 test kernel with USB Attached SCSI enabled and have a card to test with on the way. I will hopefully have and update after July 1. Thanks Edited June 25, 2017 by csmccarron 4 Quote Link to comment
saarg Posted July 20, 2017 Share Posted July 20, 2017 Did it work when using the UASP enabled kernel? Quote Link to comment
csmccarron Posted July 20, 2017 Author Share Posted July 20, 2017 It did not. I cannot even get 1 of the 4 ports to recognize a USB device in unRaid. This module could still be usefull for USB cards that support the protocol but it did not fix the issue with the StarTech PEXUSB3S44V card. Once the next RC comes out I am going to do some more experimenting with the card. Basically, the kernel enumerates the card but it does not actually see devices attached to the card.

saarg Posted August 8, 2017 Share Posted August 8, 2017 You seem to be having alot of different problems lately. Might look like you have a hardware problem with your rig. Quote Link to comment
csmccarron Posted August 8, 2017 Author Share Posted August 8, 2017 About a month ago, I had two more of my original 8 gskill memory sticks go bad, 4 have failed out of 8. I woke up one morning and the system had crashed hard! I then start figuring out which sticks were bad and eventually got the system to boot on 6 sticks of memory. Ran the memory test and it appeared to be stable. After that I returned those to gskill which replaced them. I ordered 64 gb of ECC REG memory that is compatible with my ASUS Z9PE-D16 motherboard that is guaranteed for life. Everything has been stable until I updated to rc7a. This particular card has never worked in unRaid. A couple of other users have tried but also failed. It works when the BIOS is controlling it but the moment the kernel takes over it goes to shit fast! Right now I put my original USB 3 Etron controller back in the server and all is well. There just seems to be no interest in getting this card working but it would be perfect for virtual machines. According to Startech it works on RedHat and Ubuntu LTS versions. Why it will not work on unRaid is still a mystery. I am about to perform a firmware update on the card to see if that will allow it to work any better. Quote Link to comment

BPinette Posted March 8, 2018 Share Posted March 8, 2018 I am getting the exact same problem. You seem have fixed this issue? Do you know what bios settings you switched? I really need to this work Quote Link to comment
csmccarron Posted March 8, 2018 Author Share Posted March 8, 2018 (edited) My system has been very stable on the latest version of unRaid 6.4.1. I do not remember what BIOS settings I changed. I have not tried my USB cards with 4 USB3 controllers on them yet. It stable so I do not want to mess with it. On another post I noted that I did the following: remove/change the following in syslinux.cfg append line: remove: vfio_iommu_type1.allow_unsafe_interrupts=1 change: pci-stub-ids to vfio-pci.ids syslinux.cfg append vfio-pci.ids=10de:1b81,10de:10f0,10de:13c2,10de:0fbb intel_iommu=on iommu=pt initrd=/bzroot,/bzroot-gui vfio-pci.ids are my two GTX1070 gpus.

rheumatoid-programme6086 Posted September 11, 2023 Share Posted September 11, 2023 Wondering if there has been any progress on UASP support? With USB speeds now surpassing SATA and the availability of several high-quality USB SSDs (and USB NVMe adapters), USB has become an interesting option for cache on NVMe and PCIe slot constrained systems ... but without UASP, USB SSDs cannot be TRIMed, negating all of their benefits.

To clarify what I meant by "negating all of their [usb SSDs] benefits" -- The USB SSDs I have see a 5-10X reduction in performance after they become fully 'dirty' as compared to an Ubuntu system that supports UASP and has been configured to properly TRIM them. While UASP support might not have been a big deal performance-wise for HDDs six years ago when this feature request was originally written, it's a huge deal for SSDs in the present era.

rheumatoid-programme6086 Posted January 23 Share Posted January 23 I am still facing this frustrating problem months later. The only solution I have is to remove the drives from the unraid box and TRIM them on another machine, which is a huge pain and just a ludicrously bad solution. Does anyone know if it's possible to build a custom kernel with UASP support? Considering that UASP is needed to TRIM both SSDs and SMR drives, and significantly enhances the performance of UASP-capable DAS enclosures, I'm really surprised that this relatively simple change (enabling UASP in the kernel build) has not been made.

JorgeB Posted January 23 Share Posted January 23 Last info I have is that this will be supported with v6.13 Quote Link to comment
