Beagle Bone Black and Chipsee 7" capacitive usb problem

Hello,
I’m using a Beagle Bone Black with the Chipsee 7" LCD, with the prebuilt image by Chipsee
prebuilt-debian-chipsee-hmi-20140522.tar.gz

I have many problem to use USB Audio board, and also USB FTDI RS232 VCP
Seem that the kernel note have the driver for these devices… what I can do to obtain or install this kernel/driver?

thanks in avance
Giorgio

The Chipsee 7 is supporrted out of the box with the current images:
