New device Transcend 25M3 was detected like a ASM1051 breaking the support for UAS as this one is blacklisted. But after contacting the manufacturer claimed this model has a ASM1153 and supported by UASP. So I double checked the chipset on the microscope and it is true, this is a ASM1153. syslog after attaching: [kernel] usb 4-2: new SuperSpeed USB device number 4 using xhci_hcd [kernel] usb 4-2: New USB device found, idVendor=174c, idProduct=5106 [kernel] usb 4-2: New USB device strings: Mfr=2, Product=3, SerialNumber=1 [kernel] usb 4-2: Product: StoreJet Transcend [kernel] usb 4-2: Manufacturer: StoreJet Transcend [kernel] usb 4-2: SerialNumber: S36VJ9CH307FOO [kernel] usb-storage 4-2:1.0: USB Mass Storage device detected [kernel] scsi host7: usb-storage 4-2:1.0 [kernel] scsi 7:0:0:0: Direct-Access StoreJet Transcend 0 PQ: 0 ANSI: 6 [kernel] sd 7:0:0:0: Attached scsi generic sg3 type 0 [kernel] sd 7:0:0:0: [sdd] 3907029168 512-byte logical blocks: (2.00 TB/1.82 TiB) [kernel] sd 7:0:0:0: [sdd] Write Protect is off [kernel] sd 7:0:0:0: [sdd] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [kernel] sdd: sdd1 [kernel] sd 7:0:0:0: [sdd] Attached SCSI disk From lsusb -vv: Bus 004 Device 005: ID 174c:5106 ASMedia Technology Inc.
