One more point: I have tested the disk on the same hardware with yet another hub with some interesting results: Hub with external power: ugen7.2: <vendor 0x05e3> at usbus7 uhub12: <vendor 0x05e3 USB2.0 Hub, class 9/0, rev 2.00/77.64, addr 2> on usbus7 uhub12: 4 ports with 4 removable, self powered ugen7.3: <PLATINUM> at usbus7 umass0: <PLATINUM My Drive 2.5, class 0/0, rev 2.10/1.00, addr 3> on usbus7 umass0: SCSI over Bulk-Only; quirks = 0x4100 umass0:2:0:-1: Attached to scbus2 da0 at umass-sim0 bus 0 scbus2 target 0 lun 0 da0: <PLATINUM My Drive 2.5'' 2AJ1> Fixed Direct Access SCSI-5 device da0: 40.000MB/s transfers da0: 476940MB (976773168 512 byte sectors: 255H 63S/T 60801C) Same hub without external power: ugen7.2: <vendor 0x05e3> at usbus7 uhub12: <vendor 0x05e3 USB2.0 Hub, class 9/0, rev 2.00/77.64, addr 2> on usbus7 uhub12: 4 ports with 4 removable, self powered ugen7.3: <PLATINUM> at usbus7 umass0: <PLATINUM My Drive 2.5, class 0/0, rev 2.10/1.00, addr 3> on usbus7 umass0: SCSI over Bulk-Only; quirks = 0x4100 umass0:2:0:-1: Attached to scbus2 (probe0:umass-sim0:0:0:0): TEST UNIT READY.
