Thanks Remco: I installed the utils. bcdADC is 1.00 in this case From lsusb: I can see bus 000 device 005 is these speakers and: AudioControl Interface Descriptor: bLength 9 bDescriptorType 36 bDescriptorSubtype 1 (HEADER) bcdADC 1.00 wTotalLength 40 bInCollection 1 baInterfaceNr( 0) On a linux mailist I saw: " I contacted somebody from technical support for KEF and the feedback I got was that the KEF's DAC needs to have a USB asynchronous connection (and it needs to be in control of that)" That may be a hint on to how to manage the device on OpenBSD but I cannot see how to apply it.
