VOLTRACK is unloaded and may cause Windows to display a blue screen after 255 device additions and removals.
VOLTRACK keeps a count of the number of devices it is attached to in an internal byte-size variable. This variable is incremented in response to a AEP_CONFIG_DCB command, but is not decremented. After 255 additions and removals, the byte overflows and VOLTRACK is unloaded in response to a AEP_BOOT_COMPLETE command from IOS. This can cause driver memory to be overwritten and can cause system instability.
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
