USB devices not recognized when attached after wakeup

[pwnall]

The following sequence of events results in an OSX host not recognizing USB devices that are attached to it.

1) Start VirtualBox VM 2) Put computer to sleep, e.g. close laptop lid and unplug USB hub connected to keyboard and mouse 3) Wake computer up 4) Re-plug USB hub

I'm using OSX 10.11.4 with VirtualBox 5.0.16. My USB hub is a Dell Monitor, model P2715Q.

The following lines from system.log seem relevant. Mar 18 15:24:54 pwnage kernel[0]: 043192.504567 HS05@14200000: AppleUSB20XHCIPort::resetAndCreateDevice: failed to create device, disabling port Mar 18 15:24:56 pwnage kernel[0]: 043193.752262 HS05@14200000: AppleUSB20XHCIPort::resetAndCreateDevice: failed to create device, disabling port

Please let me know if there is anything else I can do to help debug this.
