wireless usb keyboard event scheduling problem (i think)

Hi all,

I'm getting very frustraited with  my wireless keyboard and mouse as It keeps missing key press events, as well as adding repeat keypresses where they did not happen.  The problem became very apparent  within the last month or so (yes I have brand new batteries as of yesterday).  I'd really like to submit a bug report if only I knew what the problem related to, and if I knew where to send it.  I'm hoping you guys could help me do that.

info that might help

Hardware is Loigitechs s520 wireless keyboard and mouse. 

My arch install has the latest testing updates as of this date

$uname -a

Try disabling USB suspend.

Re: wireless usb keyboard event scheduling problem (i think)

Hi brebs, thanks for the help.

I don't seem to have the file you're suggesting to edit in that post .  In fact, there's nothing in /etc/udev/rules.d/ at all.

Reading through the thread though, it seems a misbehaving auto suspend could well be the cause.  Do you know where these files might be located now?  Or should I actually have some files in that folder and its my Arch install thats messed up?

By the way, if it helps you any, here's the output of:

$ for d in /sys/bus/usb/devices/[0-9]* ; do if [[ -e $d/product ]] ; then echo -e "`basename $d`\t`cat $d/power/control`\t`cat $d/speed`\t`cat $d/product`" ; fi ; done

6-3	on	1.5	USB Receiver
