you seem to have a usb device that is blocking suspect. You don't have
many usb devices:

Bus 001 Device 002: ID 8087:8001 Intel Corp. Integrated Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 003: ID 04f3:2012 Elan Microelectronics Corp. Touchscreen
Bus 002 Device 002: ID 8087:07dc Intel Corp. Bluetooth wireless interface
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

my guess would be your touchscreen.
