USB Mass Storage does not provide for TRIM/UNMAP. You need a USB adapter that specifically implements USB Attached SCSI Protocol (UASP) *and* the host needs to recognize the device as a UASP device. Run the command "lsusb -t" and look at the Driver part. If it doesn't say "uas" then it's not UASP and you can't TRIM the device. -- \m/ (--) \m/ _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
