There are two kinds of "microUSB to standardUSB" cables sold. Many of them for smartphones are "battery charging purpose only" and can't be used for data connection. I wish there is an accepted rule to apply different colors for the two kinds, but there isn't. This is because smartphones have been designed to be USB client only, unable to act as an USB host to accommodate peripherals like USB mouse, keyboard, or a printer, up to Android 2.3.3; and the most popular usage of microUSB connector has been for charging.
If you (and your users) have the kind of cable that connects smartphones to PCs, and if you are developing only for Android 3.0 and above including ICS, then what you are proposing is quite possible/ desirable.
