Hi Andy,

the command status is not allowed after the inquiry succeeded. Please
install the latest hcidump and run it with the "-X -V" parameters.

Your kernel is quite old and I am not going to debug it. Try to include
at least my -mh patch for the 2.4.27 kernel.

This is strange. Do you run your ARM CPU in big endian mode?

This actually can't be, because hcidump has no influence.

Very strange.

You might consider buying a Bluetooth sniffer.

Are you using the same kernel source as on your ARM platform?
