Yes it is possible, but I don't know of any programs to do it for you, 
which means you'll have to write your own program.

The key is to use the USBDEVFS_DISCONNECT ioctl call.  Open the correct 
device file /proc/bus/usb/BBB/DDD and send that ioctl.  It will unbind 
whichever kernel driver is currently bound to the device, leaving it 
available for someone else to use.
