Hi,
I'm trying to get bcm5974 to work with my new MacBook Pro (early 2015).
Apple seems to be using new USB IDs for this one (05ac:0273) and on
vanilla Linux 4.0.1. those aren't supported properly.
The keyboard's FN key didn't work (as well as none of the special
function keys like volume, brightness).
The touchpad only supported movement and left clicks (no scrolling or
other multitouch stuff)
After adding the new USB IDs to the kernel sources, the keyboard works
as expected but the trackpad stopped working completely (i simply copied
the WELLSPRING8 config and replaced the USB IDs).
Here's what I've found out so far:
- according to the output of lsusb (see below), the correct endpoint is 0x83
- when using TYPE3, usbmon captures only bt_data-conforming packets (8
bytes long with the last 4 bytes being 0). For each packet the driver
reports "bcm5974: bad trackpad package, length: 8".
- TYPE1 and 2 fail in _wellspring_mode()'s "/* read configuration */".
usb_control_mode returns EPIPE.
I'm using a self-compiled 4.0.1 kernel on Debian Jessie.
I'd appreciate any tips on how to proceed from where I am.
Thanks in advance,
Manuel.
