Failing to mount USB storage

[chris]

   Hi,
   First of all, after a few days playing with nard, I am really impressed
   ( thanks for all the help Ronny ).
   I have a 32GB memory stick that I can mount on my linux desktop but
   when I try the same on nard, it doesn't work, any ideas ?
   Desktop:
   ( Using: fdisk from util-linux 2.27.1 )
   Disk /dev/sdf: 30.5 GiB, 32717537280 bytes, 63901440 sectors
   Units: sectors of 1 * 512 = 512 bytes
   Sector size (logical/physical): 512 bytes / 512 bytes
   I/O size (minimum/optimal): 512 bytes / 512 bytes
   Disklabel type: dos
   Disk identifier: 0x3d743e19
   Device Boot Start End Sectors Size Id Type
   /dev/sdf1 56 63901439 63901384 30.5G c W95 FAT32 (LBA)
   mounts OK
   and from dmesg:
