> Have you tried a different USB port(s)? Yes. I plugged the USB sound adapter into a different port and the logged warnings persisted.
The laptop has 1 through 8 USB buses listed by lsusb, but only 3 external ports. Currently (and originally) attached as: Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 002: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter I temporarily tried it on: Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub which has two ports. I didn't bother trying it on both ports of that hub. Here's the full device list (probably redundant with one of the attachments above): Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 005: ID 064e:a117 Suyin Corp.
