I doubt that it is a firmware problem. Getting permission denied is a very basic OS response. If file permissions aren't working properly, then not much else on the system would work either. It's possible that the part of the system responsible for filesystem operations over USB is broken, but I expect many people would have noticed that, too.
The firmware updates actually do reformat the system directories. The directories you see via USB are non-system, and accessible by the normal reader/sreader account. Those get left alone when updating the firmware, except that some of the applications in that directory get new versions.
When in
poterm, the
df command will show you all the various filesystems mounted on the OS, and their space usage. The two filesystems seen over USB are mounted internally at
/mnt/ext1 and
/mnt/ext2; the rest are not accessible via USB.
Edit: Maybe the best way to install the programs is to copy the zip file over, and then use the
unzip command within
poterm to unpack the files. That should keep the permissions correct. You may have to delete all the
qorganizer directories first via Win7 before doing that. Run the
unzip from the /mnt/ext1 directory, so that the files get put in the right place.
Code:
cd /mnt/ext1
unzip <zip-filename>
