I own an external disk (fantec db-228u3) that mounts a ASM1153e (I read it right on board of the chipset).
Since the PC recognized the device as USB 2.0 (instead of 3.0 + UASP as it should be) I thought it was a firmware problem; so I upgraded the firmware with MPTOOL to 140509A18200 version. Unfortunately at the end of the process I had FAIL error. Now the enclosure is no longer recognized by the pc, even as 2.0. Is there a way to restore the chipset firmware or the enclosure is broke irreparably?
