Re: How I fixed my UFX III M1 Max stutters / dropouts / glitches

Firstly:
1) A FW to USB converter doesnt exist, it’s a FW to Thunderbolt adapter someone would use.

You are correct. Sorry, Maybe I wasn’t clear enough, as I didn’t want to dive in too deep.

I meant this combination (afaik, other people with fw interfaces use this with success): FW>TB Adapter and this hooked to a TB >USB Adapter.

Maggie, are you using an M1 with a usb interface? Have you had issues?

I use a MacStudio M1 Max 2022 running Sequoia. With a FF802 (via USB2) and UFXIII (via USB3) connected to it (at the same time). Both units directly connected (no hubs etc) to the USB-B Ports (USB3.2 afaik) on the mac. No issues with current DK or kexts. Tried both…

No such thing can exist. TB controller is a DMA device; it cannot be attached via USB HCI.

Don’t know how Apfel exactly connected his Ff 800 via FW to his imac.
Maybe you are right and he used TB at all.
But this is not the discussion here at all.

Fact is:
M1 USB Ports have no (general) USB problem with DK or kexts.

Haven't thought about this in a long time. Had to look it up. Two adapters must be Firewire to Thunderbolt 2 > Thunderbolt 2 to Thunderbolt 3 (USB C).

Well, all I can say is I'm jealous. I have no idea how to fix this, I've reinstalled the whole damn OS and the glitches remain, which lead me to believe it's something specific about my Macbook Pro, maybe the "M1 Pro SOC"? maybe the fact yours isnt a laptop? maybe yours has more ram?

I'm at the point where I'm about to buy a new Mac Mini M4, but if I still have issues it will go straight back to Apple.

The bus used is different even if the port is the same.

The bus is .. well.. the same. It's all connected to the M1 chip and I believe switches operational modes, sharing resources. Look up information on SMMU for more details.

Sorry, I’m not convinced there isn’t a fundamental issue with M1 apple silicon.

I'm inclined to agree with you. Then again I believe there is a silent majority who have had no issues with their audio interfaces, they just never wrote in this forum.

Why would I still get glitches, after a full clean install, with both types of drivers?

because of other variables such as your peripherals' topology, especially PCI-ish stuff like NVMe drives, hubs, external displays, which we haven't had any clear answers about in this forum. you're likely to find so many threads on this, just browse the forum.

Re: How I fixed my UFX III M1 Max stutters / dropouts / glitches

Few days ago, I came across this article
https://eclecticlight.co/2022/04/18/m1- … 3-1-gen-2/

Which lead me to an idea - Maybe, the users, here having problems with UFX III (and probably other USB3 units) could verify this:

Check your in your System Information App on Mac:
- Your unit is connected and recognized as the one (and only!) inside a USBXHCI Controller
- Speed is marked as "5 GB/s"

See my example screenshot.
- Green Box:
   -> OK (at least in my case, as the UFX III is the one and only unit connected to the USBXHCI Controller).
- Red Box:
   -> OK for my FF802 (as it uses USB2) and the controller shares some other devices and hubs...
   -> If the UFX III would appear there it would be (probably) not be OK

Please, try to post as detailed as possible (best with screenshots).
Answers like: "Doesn't work" or "Tried. Still glitches" do not help at all.

PS: This is just an idea - definitely no warranty or a solution at all...
