HID Descriptor for a BT Mouse

Hi Forum,

I'm trying to connect my old Kensington SureTrack BT mouse via hccontrol... it connects with no fuss but X,Y and Z axis are wrong. I used /usr/src/usr.sbin/bluetooth/bthidd/bthidd.conf.sample bthidd.conf as a starting point, but HID descriptor seems to be wrong. Could anyone point me on how do I find out HID descriptor, control_psm and interrupt_psm for my device?

As you can see, the device connects, no problem there.
root@nostromo:~ # hccontrol -n ubt0hci read_connection_list
Remote BD_ADDR    Handle Type Mode Role Encrypt Pending Queue State
SureTrack             36  ACL    2 MAST    NONE       0     0 OPEN
My FreeBSD version:
FreeBSD nostromo 12.1-RELEASE-p6 FreeBSD 12.1-RELEASE-p6 GENERIC amd64

Thanks in advance.
