I'm trying to track down a probem with Intuos4 WL. Connected by USB
works OK:
[  3182.316] (II) /dev/input/event8 (10:wcmEvent): c=0 i=1050626 t=1c
s=343955190 x=18061 y=9959 b=0 p=0 rz=0 tx=28 ty=32 aw=0 aw2=0 rw=0 t=0
px=1 st=0 cs=4 

so serial is 343955190 (hex 148056F6), 
id 1050626 (hex 100802) or hex 10080A depending on the tool.

now hid-wacom: 

[ 22269.565] (II) /dev/input/event8 (10:wcmEvent): c=0 i=0 t=1 s=1 
x=32822 y=11354 b=0 p=0 rz=0 tx=0 ty=0 aw=0 aw2=0 rw=0 t=0 px=1 st=0 cs=4 

so serial = 1, id =0

part of the code related to reporting:

input_report_key(input, BTN_TOUCH, pressure > 1);
input_report_abs(input, ABS_DISTANCE, ((data[9] >> 3) & 0x3f));
input_report_key(input, BTN_STYLUS, data[1] & 0x02);
input_report_key(input, BTN_STYLUS2, data[1] & 0x04);
input_report_abs(input, ABS_X, x);
input_report_abs(input, ABS_Y, y);
input_report_abs(input, ABS_PRESSURE, pressure);
input_report_abs(input, ABS_MISC, wdata->id);
input_report_key(input, wdata->tool, 1);
input_event(input, EV_MSC, MSC_SERIAL, wdata->serial);
input_sync(input);

values on kernel side are correct, I can prove it :-)

My guess is that usbChooseChannel is picking WCM_PROTOCOL_GENERIC 

I understand that usbInitProtocol5 should initialise protocol v5 but I can't 
find where it's called.
The same for usbInitProtocol4.

Any hints?


P.S. How to set debug level for tablet before connecting? I what to debug 
connection process, but 
xsetwacom --set "Wacom Intuos4 WL pad" TabletDebugLevel 10 can't work if there 
is no tablet connected.
