Hi,

this is really a shot in the dark, but...
Would it possible, that the USB-stick is carrying a filesystem, which
lacks the support of enough ijnformations, rsync needs to operate
corrrectly (especially: file times?
Concerning the wear out of usb-sticks (and flash media in general):
There are specialised filesystems out there (dont remember what
exactly their names were), which take care of a "flashy" environment
(spread writes to different parts each time),

HTH!

Best regards,
mcc
