Since the usb headset works (partially) on the mac mini, I didn't check the system log (see below)

Google shows various solutions:

Microphone muted - it is, but it doesn't stay connected long enough for me to unmute it.

echo -n '0000:00:1d.7' > /sys/bus/pci/drivers/ehci_hcd/unbind
where 0000:00:1d.7 is to be replaced by the correct PCI address. This will reconnect the device under USB 1.1

The command is accepted, but the usb headset does not appear at all thereafter, so I'm not sure how to fix this.

Note that on the mac mini, the "cannot submit datapipe for urb 0, error -28: not enough bandwidth" appears just once and the usb headset speakers, but not the microphone, work after that. The microphone is not muted in alsamixer or pulseaudio.
