CM10: How To Get USB Connection Prompts When Connected To Computer.

[st_7]

I've been using CM9 & now CM10 on my touchpad for past few months. I like to know how can i get USB Connection prompts just as you get when you connect any android phone to computer. I'm asking this because when I connect my Touchpad to computer it straight goest MTP or PTP(Camera connection type) but never asks me whether to charge or mount it as mass storage device. I can't deselect the MTP option either I only can change between MTP & PTP options.

Can some body shed some light on this?
