Tool/software: Linux
Hi,
we are operating an mSATA device behind a TUSB9261 (v1.05) under Linux 3.14 with ext4. The usb-storage driver tells us that the WRITE SAME SCSI command is not supported by the device.
There is still the UNMAP SCSI command which could activate TRIM. However, does the TUSB firmware translate this command into the TRIM ATA command and provide support for that?
Are there any other ideas how to trigger TRIM in BOT mode?
Thanks for every hint!
