Dear Greg,
I am still monitoring the behavior. Please let me come back to you
when I am sure about that.
Where should I send the "patch"? As I told you it is not a 100% fix!
I will continue monitoring this week whether Trackman/Keyboard will
hang; I will then let you know.
Best Regards,
Kyprianos

Dear Greg,
With regard to buffer overflow, check the following thread, at the end

Ah, you were referring to a device bug, not a kernel issue, that makes
more sense.
Did you try the "always poll" quirk for this device to see if that
solved the issue for you? That might be all that is needed.
thanks,

you mean the following in /etc/default/grub/
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1
usbhid.quirks=0x046d:0xc404:0x00000400"
?
Command "lsusb" gives for the TrackMan Wheel :
Bus 002 Device 009: ID 046d:c404 Logitech, Inc. TrackMan Wheel
Yes, did you try that? What happened if you do?
thanks,
greg k-h
.
I have done it for the TrackMan Wheel only
(usbhid.quirks=0x046d:0xc404:0x00000400"), not for the keyboard
("0x0a81:0x0205:0x00000400"). I did this yesterday.
Now It is much more stable, don't know whether this is a coincidence. Still
both TrackMan and Keyboard freeze occasionally.
But less? If so, we should apply this as a "real" patch, care to make
it up and send it in? If not, we can, but it's always good for you to
get full credit for the change if you want it :)
thanks,
greg k-h
.
Unfortunately the problem still continues, both the USB Trackman Wheel
and the Keyboard freeze very often!
These days I ran the "Software Updater" several times, I don't know
whether this relates/contributed to the reappearance of this issue.
