Hi,
In net/bluetooth/core.c there is:
if (session->input) {
hidp_send_ctrl_message(session,
HIDP_TRANS_SET_PROTOCOL | HIDP_PROTO_BOOT, NULL, 0);
session->flags |= (1 << HIDP_BOOT_PROTOCOL_MODE);
session->leds = 0xff;
hidp_input_event(session->input, EV_LED, 0, 0);
}
which effectively sets the boot protocol for all input devices. To
support some scroll wheel mice they need to be put into report mode, though:
if (session->input) {
hidp_send_ctrl_message(session,
HIDP_TRANS_SET_PROTOCOL | HIDP_PROTO_REPORT, NULL, 0);
session->leds = 0xff;
hidp_input_event(session->input, EV_LED, 0, 0);
}
I assume that's safe. Solaris for instance, initializes all devices in
report mode by default. It never even tries boot protocol.
Maybe it would make sense to have a userspace interface to switch the
mode from within hidd.

you assumption is wrong. The flags variable doesn't change anything. You
might wanna try 2.6.20-mh1 which is the first one that includes the
official report mode support.
