the bluetooth device stopped working after migrating to the new laptop, a Dell 
Inspiron 9400, with the above error message on issuing a btconfig ubt0 
<command>. This used to work with the old laptop, a Dell Inspiron 9300, and 
same kernel, configuration and userland - (netbsd-i386-3.99.21).

Below is the boot message of the new laptop:

ehci0 at pci0 dev 29 function 7: Intel 82801GB/GR USB EHCI Controller (rev.

On the old laptop the device was attached to 

ubt0 addr 2 -> uhub1 -> usb1

but on a Inspiron 9400

ubt0 addr 3 -> uhub5 -> uhub4 -> usb4

I've tried different kernels including GENERIC, GENERIC.MP and GENERIC.MPACPI 
to no avail. Any suggestions?
