Hi Richard, I'm glad you have paid attention to this problem.
A few weeks ago I've upgraded my Ubuntu version from 14.04 to 16.04 and faced with this issue. Now every time before connecting my USB sound-card I have to kill the 'fwupd' process.
Here is output from the 'dfu-tool list' command:

 - When 'fwupd' is running:
Found 1397:0501 [v1.0]:
  Status: cannot get device state: transfer failed

 - After killing 'fwupd' and replugging sound-card:
Found 1397:0501 [v1.0]:
 Mode: runtime
 Status: OK
 State: appIDLE
 ID: 0
  Cipher: none
  Region 0x00: Zone:0, Sec#:0, Addr:0x00000000, Size:0x0000, Caps:0x3

The 'fwupd' process itself using 1.2 - 1.8 % of CPU (model name: Intel(R) Core(TM) i3 CPU M370 @2.40GHz).
Also please check the attachments: lsusb (with connected working/not-working sound-card) and fwupd verbose output (started with working sound-card/connecting sound-card when 'fwupd' running) diffs. Hope this will help.
