[K12OSN] Thumbdrives not recognized by Centos5 server

[Peter Scheie]

My money is on Sonja's point 2.c, permissions for /dev/fuse.  I have 
this problem appear periodically on a K12LTSP 5 server.  The problem is 
caused, I think, by reboots which /dev/fuse to get recreated with 
default permissions, which manifests itself in empty USB devices.

Several students with SanDisk Cruzer thumb drives reported issues with certain sizes of these drives (smaller ones are the problem... over 2GB seems to work fine.) I'm running Edubuntu 7.04, not K12LTSP, but might be a related problem. I've seen the issue on many forums but no solutions. Since other brands work fine for me.... Mr. Hodson, you might want to try another brand might to see if it will bandaid the issue for you until a solution is found.
