Hi Daniel,

> What Bluetooth host controller are you using?

It is a USB device (0a5c:4500), part of a BCM2046 sitting in a MacBook
Air. The driver is btusb.

> Which part are you testing (Magic TP or mouse)?

Magic trackpad.

Interesting. Clearly not a HID problem, then.

The input events stop coming when I have more than four fingers on the
pad, but they start again if I remove the excess fingers. As if the
transport layer chokes on messages longer than some value...

Thanks,
Henrik
