ConfigFS expects idVendor and idProduct values to be prefixed with 0x.
Without this change, google-crosshatch shows as a device with 0:0 as the
idVendor/idProduct in lsusb:
Bus 001 Device 004: ID 0000:0000
This confuses VirtualBox: it has trouble detaching this device from
a virtual machine, so one must manually use ifconfig to bring down the
old USB network connection before reattaching.
With this change, the idVendor/idProduct is correct:
Bus 001 Device 004: ID 18d1:d001 Google Inc.
This issue also seems to affect other devices with ConfigFS, such as the
Nexus 5:
