Hello there!
I have a couple of Quectel EC25-AUX that I use with Asterisk PBX’s.
They work flawlessly, but after some weeks, they started giving descriptor error -71.
Rebooting the host doesn’t work, sometimes it requires physical unplug, sometimes requires first unplug then reboot and plug back in.
They’re interfaced by USB, and all three devices give the same problem, we were able to replicate it by connecting, once it works disconnect and reconnect it, then it gives this problem.
Host1: Custom server running VMware ESXi 7.0 with USB Passtrough
Host2: RPi4 8GB running Raspberry PI OS 64 bits.

The dmesg says May since I’ve been fighting with this since May, and posted here in another subforum and no one saw it
I tried other usb cables, same behavior. We suspect about the dautherboard or whatever it’s called, but we have no idea. Our modules are all PCIe.
I’d be very thankful if anyone gives me a line of sight.
Regards,
Alan.
