Comment 5 for bug 587044

For what it's worth:
The 3 USB disks reported turned out to be the 4 inputs of my USB card reader.
All of them took a long time to find out to be empty, upping system load to 6.
On the same USB bus, there is a hub with a WiFi network stick.

Bus 002 Device 005: ID 050d:945a Belkin Components
Bus 002 Device 004: ID 058f:6362 Alcor Micro Corp. Hi-Speed 21-in-1 Flash Card Reader/Writer (Internal/External)
Bus 002 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
