The #1 example does show using a comma.
But the #1 example says to use an "extended character" - whatever that is in en_M$ language.
I
think that in 8.3 terms it means non-alphanumeric.
Try: F_NAME.TXT (anything that fits in 8.3 using an underscore)
Hmm...
We also need to see the mount options of /mnt/us while it is in USBfile mode.
Will probably require someone who has Wifi SSH enabled to look that up for us.
(The options will tell us how the VFAT driver is handling filename case.)
Here is a quick (non-Kindle) example of a VFAT option string:
Code:
/dev/sde1 on /media/A80E-9247 type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks)
