Are these *large* thumbdrives (>= 64Gig)?
I have tried with both large (256 GB) and small (4 GB). The small drive is definitely FAT32. Both have worked in this computer in the past. I have also just found it treats a USB CD/DVD drive in the same way; appears in lsusb but not in df or in the file browser. This is really annoying because the reason for plugging in the thumbdrive was to burn a CD. This DE doesn't appear to have a disk mounter. Chris.
