Thanks for a fantastic and very useful program. I have a non-Intel Mac Mini and use a Keyspan receiver. After power-up the Mac does not discover the Keyspan receiver (at least it does not show in the menus). if a disconnect and connect the receiver again it suddenly appears in the menus and eveything works OK until I shutdown the computer then the same happens again.

Does anyone recognize this problem and have a tip how to resolve it?

Hello Mats,

Remote Buddy relies on IOKit for recognizing existing and new 
instances of a IOUSBDevice object that represents a certain USB 
device. If Mac OS X knows about the device, Remote Buddy will 
automatically know about it, too.

Please have a look in System Profiler's USB info the next time your 
device is connected but does not seem to be recognized. You shouldn't 
find it listed there either. Which then means this is an issue at the 
OS or hardware level. In that case, this Apple document may provide 
you some help:

http://docs.info.apple.com/article.html?artnum=58033

Detaching the receiver and resetting the NVRAM and PRAM may also help:

http://docs.info.apple.com/article.html?artnum=2238

Doing the latter helped me years ago when Apple's USB keyboard and 
mouse would not be recognized by a certain USB port (I'd always have 
to replug them - or plug them into another USB port).

Best regards,

Felix,

Actually, the device appears in the System Profiler but is not found by Remote Buddy. Strangly enough it seems always to help to unplug and plug the device while Remote Buddy is running. ....

I will check the links you sent me ans see if I can find any help there!

Thanks, 
Mats

Does it appear there *after* replugging or already before?

If it appears in System Profiler but not in Remote Buddy, please do 
the following the next time you experience the problem:

1) Enter this line into Terminal.app:

ioreg -l -w 0 >~/Desktop/ioregDump.txt

2) send the file ioregDump.txt from your Desktop to info@iospirit.com.

I can then take a look at what is going on on the IOKit level.

Best regards,

I am having a similar (but different) problem with the Keyspan Receiver. When I plug it in- my mac recognizes it (listed under USB in system profile) but the red light on the receiver stays on and it will not accept any commands by the remote. 
HOWEVER... If I cover the red light with my hand or some other object--- I can see the red light go off and the receiver responds to ALL signals properly. Any clues???

Felix,

I sendt you a log to your infomail about my problem. Have you had any chance to look at it.

I have upgraded to 1.8 but the problem still persists.

Hello Lou,

the red light staying on or blinking (depending on model) means that 
the device has not been initialized. Why it would suddenly initialize 
(=> which is done by sending a few bytes over to the device to say 
hello) due to physical interaction is beyond me, sorry.

Mats,

thanks for the file.

I've been at Mac Live Expo since Wednesday and had to intensily 
prepare before that. So I could only have a look right now.

I've found an anomaly inside the log. There are two user clients 
attached to your USB device. In this case, each user client does 
represent a different application accessing the USB device from user 
space. Or said differently: it looks like two applications are trying 
to access the Keyspan IR receiver at the same time with the two 
possibly entering a race condition that prevents the device from ever 
successfully initialising.

Do you use - or did you use - any other software that contains drivers 
for the Keyspan receiver?

If so, did you completely uninstall it by completely deleting it?

Could you make sure Remote Buddy doesn't get started on system 
startup, then rebooting (or whatever would lead to the problem), then 
- without Remote Buddy running - make another ioreg dump and send it 
over to me?

Thanks in advance!

Best regards, 
Felix

Felix,

Your were completely on the right track. I hade some "left-over" installed from another product that used the Keyspan receiver. I managed to remove this manually and now RemoteBuddy works at power-up.

Thanks very much for your help.
