No, I don't think that's the case, as it does work without this when rebooting
the system.   I think the lines which gives it away are:
   hub.c: new USB device 00:1f.2-1, assigned address 2
   usb.c: USB device not responding, giving up (error=-110)

During a reboot, (remember I haven't loaded the drivers manually at this stage)
the interface is detected automatically:
   hub.c: new USB device 00:1f.2-1, assigned address 2
   usb.c: USB device 2 (vend/prod 0xd5c/0xa002) is not claimed by any active driver.

I thought that maybe the usb adaptor needed to "warm up" but that doesn't
explain why hotplugging works. This morning, I booted from cold with the
adaptor disconnected.  When I plugged it in , it worked immediately.
