Could it be because Linux considers the drive unformatted? No. This has nothing to do with what Linux thinks. Those error messages are sent by the stick itself. The stick is telling you that those sectors cannot be read. > It does > have some filesystem (presumably FAT), but I didn't format it - perhaps it > starts with something strange that Windows ignores? In fact the stick has 2 LUNs, but your usbmon log shows that Linux is looking at only the first one. Probably you don't have CONFIG_SCSI_MULTI_LUN set in your kernel. My guess is that the first LUN is meant for some special purpose and the second is what you want to use. It should show up as /dev/sdb.
