The relevant info in the logs is that the device does not recognize the « Synchronize cache » command. You may want to add a « kernel quirk » in scsi_da.c, it consists of adding an entry for your memory stick and telling that it does not support that command. You can use the following PR as a model for chaning the kernel, it's a PR I wrote for my own memory stick: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/54786 But first, be sure to upgrade your system to the latest current FreeBSD sources (checkout HEAD). Most quirks are now no more needed due to a recent refactoring of USB mass storage drivers. Cheers, -- Jean-Baptiste Quenot http://caraldi.com/jbq/
