communication between usb and uC

[k1_zav]

Hi there.
I have some files in a mass storage memory (a flash memory)>> (COOL DISK) and I want to read these files by a microcontroller(µC).(Is it feasible??)
this flash uses usb standard.
First I must know how these devices work and then how I can read data from this device.
who can shed a light on me?
I want to know how D+ and D- work in usb standard.

thanks in advance.
Regards.

I won't say it's impossible, but it's highly complicated. The reason is that you need a usb host to read data from a usb device. On the other hand, if you can get your hands on an OTG controller, things may be slightly easier.
