Western Digital Elements 2620 not shown on the 400 MByte port

Hello, My Acer C720, running FreeBSD 14.0-CURRENT r1400094, does not show an attached external USB disk, no lines in /var/log/messages in the moment of attaching, nothing in # usbconfig dump_all_desc Only the small light goes on on the disk. On the other USB port with 40 MByte transfer rate it says fine: Sep 14 10:27:00 c720-1400094 kernel: usb_msc_auto_quirk: UQ_MSC_NO_GETMAXLUN set for USB mass storage device Western Digital Elements 2620 (0x1058:0x2620) Sep 14 10:27:00 c720-1400094 kernel: usb_msc_auto_quirk: UQ_MSC_NO_TEST_UNIT_READY set for USB mass storage device Western Digital Elements 2620 (0x1058:0x2620) Sep 14 10:27:00 c720-1400094 kernel: usb_msc_auto_quirk: UQ_MSC_NO_PREVENT_ALLOW set for USB mass storage device Western Digital Elements 2620 (0x1058:0x2620) Sep 14 10:27:02 c720-1400094 kernel: usb_msc_auto_quirk: UQ_MSC_NO_SYNC_CACHE set for USB mass storage device Western Digital Elements 2620 (0x1058:0x2620) Sep 14 10:27:02 c720-1400094 kernel: usb_msc_auto_quirk: UQ_MSC_NO_PREVENT_ALLOW set for USB mass storage device Western Digital Elements 2620 (0x1058:0x2620) Sep 14 10:27:02 c720-1400094 kernel: usb_msc_auto_quirk: UQ_MSC_NO_TEST_UNIT_READY set for USB mass storage device Western Digital Elements 2620 (0x1058:0x2620) Sep 14 10:27:02 c720-1400094 kernel: usb_msc_auto_quirk: UQ_MSC_NO_START_STOP set for USB mass storage device Western Digital Elements 2620 (0x1058:0x2620) Sep 14 10:27:02 c720-1400094 kernel: ugen0.2: <Western Digital Elements 2620> at usbus0 Sep 14 10:27:02 c720-1400094 kernel: umass0 on uhub0 Sep 14 10:27:02 c720-1400094 kernel: umass0: <Western Digital Elements 2620, class 0/0, rev 2.10/10.23, addr 5> on usbus0 Sep 14 10:27:02 c720-1400094 kernel: umass0: SCSI over Bulk-Only; quirks = 0xc105 Sep 14 10:27:02 c720-1400094 kernel: umass0:1:0: Attached to scbus1 Sep 14 10:27:02 c720-1400094 kernel: da0 at umass-sim0 bus 0 scbus1 target 0 lun 0 Sep 14 10:27:02 c720-1400094 kernel: da0: <WD Elements 2620 1023> Fixed Direct Access SPC-4 SCSI device Sep 14 10:27:02 c720-1400094 kernel: da0: Serial Number 575838324137344831564E50 Sep 14 10:27:02 c720-1400094 kernel: da0: 40.000MB/s transfers Sep 14 10:27:02 c720-1400094 kernel: da0: 1907697MB (3906963456 512 byte sectors) Sep 14 10:27:02 c720-1400094 kernel: da0: quirks=0x2<NO_6_BYTE> Other disks do fine on the 400 MByte port.
