Crash on mouse movement

[gwieser]

System (kind of exotic :-):
SLED 10 SP1 64bit
kernel: 2.6.16.46-0.14-smp
python: 2.4.2-18.10
uinput is loaded, udev rules are in place
Logitech MX510: Bus 001 Device 004: ID 046d:c01d Logitech, Inc.

--------------------

georg@blaine:~/Desktop/pystromo> ./input-remapper.py -v
Using output: <devices.OutputDevice object at 0x2af091a55d90>
Using device: <InputDevice "mx510" on 1 device nodes>

As soon as I move the mouse I get a crash with the following error:

Traceback (most recent call last):
  File "./input-remapper.py", line 127, in ?
    events = devices.read(blocking=shouldBlock)
  File "/home/georg/Desktop/pystromo/devices.py", line 33, in read
    events.extend(devices[dev].read(dev))
  File "/home/georg/Desktop/pystromo/devices.py", line 126, in read
    return self.readNode(node)
  File "/home/georg/Desktop/pystromo/devices.py", line 143, in readNode
    event = self.Event(node.read(self.Event.size))
  File "/home/georg/Desktop/pystromo/events.py", line 36, in __init__
    self.unpack(raw)
  File "/home/georg/Desktop/pystromo/events.py", line 94, in unpack
    tup = struct.unpack(self.format, raw)
struct.error: unpack str size does not match format

I have a N52 too, it also crashes with a similiar output, not when I press a button but after a seemingly random time.
Contact me if I can run some tests for you.

I suspect this is due to your system being 64-bit.
Could you try changing line #16 of events.py:
 format = 'LLHHl'
to:
 format = 'LLHHi'

or, failing that:
 format = '=LLHHi'
or possibly even:
 format = '=LLHHl'

That seemed to work with the MX510, thanks! I will try with my n52 soon but
I suppose it should work too. A question: What about the n52`s mode
switching (red/green/blue). Can this be implemented with this method or
would it require a specialized driver?

Best,
Georg

Excellent, that fix will go into the next numbered release then. Which should be soon.

Implementing mode switching is certainly in the plan, and I should be able to get on to that after the next release. :)
