good, thank you :)

hmmm... that is strange... it seems device re-attached itself and then
ugen(4) driver attached to it.

i see. the first call to bcmfw_device_bcmfw_check_device() is to turn
*on* device nodes under /dev. the second call to bcmfw_device_nodes() 
is to turn them *off*

since you did not get any errors from bcmfw_check_device() and  
bcmfw_load_firmware() then i suspect the bcmfw(8) actually worked and
transferred firmware into the device.

it appears that device resets itself *after* firmware was downloaded and
that caused "detach" message you saw. when device is detached Netgraph
node is destroyed and that causes "Could not NgSendMsg()" error. next,
ugen(8) driver attached to the device. i wonder why. we already claimed
that device, so why just not re-attach the same driver? got to get back
to USB source code...

thank you very much for trying it and reporting the results. i will try
to find workaround.

thanks,
max
