It would be good to change the install script at KD7LM0 web site.

It would be good to to mention that this is optional at KD7LM0 web site.

I like the idea of not having to use sudo.  I will try to change the
permission on the appropriate directory.

Does anyone have a list of what those directories are?

I did that (see last sentence in #1) and I still got the error that it could
not find usrp_fpga.rbf.
Is this file supposed to be somewhere else to?
 
Isn't' there a better method to set this up with the CVS release?

Why the the UsrpInstall wiki mention that you need hotplug for setting up
USB device permission?

 

I am on FC4, how can I make sure that I have permission for the USB?

 

I do not see any usrp or usrp.usremap in the /etc/hotplug/usb directory but
I do see some for the USB camera that I connected.

 

Can I get more information about the scrip that set the device permission
mention in the UsrpInstall wiki?

I am running on FC4, any help with those that have experience or have USRP
running on FC4 would be appreciated.

I did install and will do it again making sure that there are absolutely no
errors.  Somehow I must have missed an error message about not being able to
create the /usr/local/share/usrp directories.  I will try it with setting
write permission for the share directory.

 

Thanks for the help.
