Extra info:
The second USB drive could not be formatted NTFS. Formatting the USB Flash
Drive in Windows XP to FAT32 (vfat) worked at first. It opened correctly in
Windows 7, then Linux, where I copied files to the root folder, then in Windows
7, where I added a folder.
However, when the drive was opened in (yet another) computer running Lubuntu
12.04.1 the stick could not mounted or read. Data seems to be lost again.

==end==
The drive is recognized as a SCSI removable disk. I am not sure, but may
it have to do with that? See e.g. for the same usb_device.vendor_id:
http://lists.freebsd.org/pipermail/freebsd-
gnome/2008-January/019095.html (hal: usb flash drive is seen as scsi
device)
The drive is recognized in Windows 7 with system errors. Checking
Removable Disk with fix first stalls, the next run it says that there
are no errors, but I see no files or folders, but file space is taken by
'something'. Back to Linux the system reports 2 folders: FOUND.000 with
9999 files (FILExxxx.CHK), and FOUND.001, with 6845 files
(FILExxxx.CHK). I think that the file system is broken.
The file system corruption seems to happen in Ubuntu, but it may be
hardware specific. If it happens with more hardware, I think that this
is a severe bug.
The first drive did not give any problems anymore. NB It was a while ago
that I formatted this disk. According to the info it seems to be FAT16
now, but it works.
