Connecting an Atmel AT91SAM7X microcontroller

[Frank J. Beckmann]

Hello,

I'm trying to connect an Atmel AT91SAM7X microcontroller to my system running 
FreeBSD 8.1-PRERELEASE. The Linux instructions tell me to use the usbserial 
module via

modprobe usbserial vendor=0x03eb product=0x6124

So I added

product ATMEL AT91              0x6124  AT91 Microcontroller

to

/usr/src/sys/dev/usb/usbdevs

and

        {USB_VPI(USB_VENDOR_ATMEL, USB_PRODUCT_ATMEL_AT91, 0)},

to

/usr/src/sys/dev/usb/serial/ugensa.c

The microcontroller now gets recognized but attaching it fails:

ugen1.2: <vendor 0x03eb> at usbus1
ugensa0: <vendor 0x03eb product 0x6124, class 2/0, rev 1.10/1.10, addr 2> on 
usbus1
ugensa0: No interfaces
device_attach: ugensa0 attach returned 6
ugensa0: <vendor 0x03eb product 0x6124, class 2/0, rev 1.10/1.10, addr 2> on 
usbus1
ugensa0: No interfaces
device_attach: ugensa0 attach returned 6


usbconfig -d ugen1.2 dump_all_config_desc

gives:

ugen1.2: <product 0x6124 vendor 0x03eb> at usbus1, cfg=0 md=HOST spd=FULL 
(12Mbps) pwr=ON

What do I have to do to connect that microcontroller?
