Use the latest version of MultiBeast for Mojave and choose (among your other configuration choices): Drivers > USB > Remove XHCI USB Port LimitHi...sorry to ask...on MultiBeast latest release..How can we fix the USB? I been trying for long time and so far no luck...
I have Mojave as well 10.14.4. That clears things up then, I will apply the same patch. Thank you for your help!An SSDT for what use? What version of macOS?
I'm not currently using an SSDT for USB, if that's what you want. I'm using the USB config.plist patches that are in the latest MultiBeast for Mojave release.
Your SSDT should not have any affect on the ASMedia USB ports. The SSDT should only deal with the Z370 chipset USB ports.Hey @Stork and @pastrychef I have finally gone up to Mojave now Avid have released the updated Pro Tools, and thought everything went smoother than any update I have done ever! However, now the ASmedia USB 3.1 Gen 2 ports only seem to be working at USB 2 speed, and I can't get them to work at full speed no matter what I do.
Problem is I am not entirely sure when I lost the higher speed. I have 2 USB3.0 drives that would both show up as 5gb/s under system profiler (and still do on the intel controller) in the past so I definitely had the full speed previously, but now all I get is 480mbs.
I have tried chucking out the SSDT I made and applying the latest port limit patch which gets clearly everything working as the internal lights show up again in system profiler but still the as media ports are stuck at USB 2 speed. I have double checked everything in the BIOS and all that appears correct. I have recently updated the BIOS to 1901 but the release notes mention nothing about USB changes, although they do for 1801, which has me wondering if maybe something then broke the way macOS sees the ports and I didn't notice till now?
This is driving me insane as I had them working and have no idea why they are not now. Could it be anything in a clover update? I made sure that and all my kexts were totally up to date before updating to Mojave. All I see is that the ASM2142 is native supported in macOS so have no idea why I have lost all my speed. Hopefully one of you may have some ideas to try. I am only using the red 'A' type port and not the Type C, but then I have only used this port and know for sure my drives would connect at 5gbs.
I didn't think that the ASMedia ports would be affected in the slightest by the intel ones / SSDT but have been trying anything I knew had changed in the past few months. I even removed my NVME drive as that was a recent addition but it makes no difference. I think a BIOS downgrade is about all I have not tried yet to test with my hardware!Your SSDT should not have any affect on the ASMedia USB ports.

Also, do not trust what System Information > USB reports. It has been reporting the incorrect USB 3.1 gen 2 speeds for a long time and, as far as I know, has not been fixed.
I will test the ASMedia ports on my system a little later and report back...
I don't currently have a true USB 3.1 gen 2 device to test, but I tested a USB 3.1 gen 1 attached SSD.I didn't think that the ASMedia ports would be affected in the slightest by the intel ones / SSDT but have been trying anything I knew had changed in the past few months.

The speed is definitely slower checking with blackmagic on my ASMedia ports than the intel USB3 gen1 ports so I don't think that the speeds reported is just cosmetic. Definitely interested to see what you or @Stork find with your rigs.
I just did the same test with a Samsung SSD drive attached.I don't currently have a true USB 3.1 gen 2 device to test, but I tested a USB 3.1 gen 1 attached SSD.
I have a USB 3.1 gen 2 NVMe adaptor but I don't currently have any unused NVMe SSDs to plug in to it for testing... But I highly doubt there would be any issues.
