Default cant mount storage on CM11

hey guys,
i am having a problem..i cant mount storage on my laptop.i have CM11 installed..when i connect my phone using USB mount storage, i get nothing in computer.. in device manager,i have device named "EndeavorU",it says "The drivers for this device are not installed. (Code 28) There are no compatible drivers for this device."
i know i can use MTP as mass storage but i want USB mount storage because its faster that MTP..
i am running windows 8.1
what to do??
