This error is different ("operation not permitted" versus "Device or
resource busy"). Is your source build using a different user than the
Gentoo build? (Some distributions have a specific NUT userid instead
of using "nobody" - not sure how they do it in Gentoo).
I'm compiling it with root but I followed the instructions (I think):
./configure --with-user=ups --with-group=nut
What user should perform the #8 step, /usr/local/ups/bin/upsdrvctl start
You can run upsdrvctl as root, and the driver will change to the user
you listed above. If you change the parameters to ./configure, you
will need to run "make clean" before "make all" and/or "make install"
The key is to make sure that the installed udev files match that
username as well. (At the beginning of this thread, you quoted a udev
rule which set the USB device node to user "nobody", which probably
isn't in group "nut".)
I changed that.
Is there any way to see what these two devices are?
May the UPS one should be root:nut
$ ls -l /dev/usb
total 0
crw-rw---- 1 root root 180, 96 May 11 00:40 hiddev0
crw-rw---- 1 root root 180, 97 May 11 00:40 hiddev1
PS!
I changed code in drivers/libusb.c
It doesn't fix my problems but I think is nicer code.
