VirtualBox 4.3.6, ROS 0.3.16RC from SF.net, most probably r61894.
I tested my wireless mouse Logitech M235 2nd gen connected via Unifying dongle with the ROS VM under Windows 7 x64. Added after full bootup, then made a full reboot cycle, rebooted again and then removed it. 3 CONTable exceptions occured on removal:
Assertion 'FALSE' failed at C:/Users/ZWabbit/workspace/reactos/trunk/reactos/drivers/usb/usbccgp/pdo.c line 758
Debug logs for all 3 ROS cycles are attached.
