Marcel,

I finally had a chance to patch kernel and try hid2hci  with this patch
kernel.   I still got success. but hcitool dev never reported any
devices.   I looked at the code in hid2hci, my diff is below. 

I first made the change at 204.  And found that the /dev/usb/hid was not
opening.  Finding me /dev to be /dev/usb I changed line 79 to match my
file structure.   

Now I get
hciconfig
hci0:   Type: USB
        BD Address: 00:07:61:07:ED:A9 ACL MTU: 192:8  SCO MTU: 64:8
        UP RUNNING PSCAN ISCAN
        RX bytes:131 acl:0 sco:0 events:14 errors:0
        TX bytes:32 acl:0 sco:0 commands:13 errors:0

But not input from mouse and keyboard.
