USB streaming stops after a period of time – MAC

>Are both devices (CQ and Mac – and no others at this moment!) connected to the same, correctly grounded power net?

Yes sir all is connected to the same, grounded circuit. The first time I noticed the problem was in the middle of a band rehearsal. Prior to that it had been running in the same config without issue for 3 months. It almost sounds like what you would hear when sample rates aren’t matched, but quite worse. I initially thought it was hardware as well, I’ve replaced the cable with a known good and working cable.

Since the port change it only occurred once and very briefly with the ‘new’ port in use. I am going to start relying more on the SDCARD for recording live sessions. We use 20 channels so I hope that doesn’t have an issue either.

I’ve reinstalled OS+apps, flashed firmware, replaced cables. I’m out of troubleshooting ideas and for support to reply that simply it’s because of differences with USB ports is a little mind blowing!

But that suggests that the USB connection on your CQ is basically working – even if this fact is still not sufficiently useful to you at the moment.

Agreed that the a USB handshake occurs and the devices see each other. It also transmits the default track information and identifies it appropriately to the Mac. In a new wrinkle, during rehearsal tonight the unit disappeared from the (ethernet) network and the LED aside the port started blinking rapidly from yellow to green. Performing the reset procedure did not produce helpful results and I eventually had to hard reboot, after some several *minutes* I was able reconnect. Because of the aforementioned USB issue I was recording to the SDCARD. I suppose yanking the power caused the files not be closed properly and they ended reporting that they were 0 bytes to the Mac, interestingly the SDCARD does show it consuming 10GB of space, so there’s data somewhere. Show invisible files is on, but I don’t see any other files on the card.

Anyhoo I could probably figure out how to wireshark the USB connection but I think I’m going to request a warranty RMA instead of throwing any more hours at this. I want to mention that the USB issues started suddenly the other night, no major infrastructure or otherwise changes occurred recently. I do have a support ticket open. I will make a post for posterity in this forum detailing the issues which have led up to my requesting warranty action.

Hello, I do have the same problem, that usb stops working on a Mac Studio and a Mac Mini, with the CQ-12T. I have that device for nearly a Year now, but the problems have been starting some month ago.
The only things I changed were the usual Mac Updates and the CQ firmware update to version 1.2 and now 1.2.1.
Maybe there is a bug in the firmware, because it has been working without any problems before.
