Hello! Any time I attach an external usb-flash "disk", I get the following messages logged. The device seems to work, but I'm uneasy -- what do they mean? umass0: Memorex TD 2C, rev 2.00/1.00, addr 2 da1 at umass-sim0 bus 0 target 0 lun 0 da1: <Memorex TD 2C 1.00> Removable Direct Access SCSI-0 device da1: 1.000MB/s transfers da1: 119MB (243712 512 byte sectors: 64H 32S/T 119C) umass0: Phase Error, residue = 0 (da1:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 umass0: Phase Error, residue = 0 (da1:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 umass0: Phase Error, residue = 0 (da1:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 umass0: Phase Error, residue = 0 (da1:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 umass0: Phase Error, residue = 0 (da1:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 The system is 5.3-stable circa Dec 19 running on a Pentium2 laptop. The USB controller is detected as follows: uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0x1040-0x105f irq 11 at device 7.2 on pci0 usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0 usb0: USB revision 1.0 uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0x1040-0x105f irq 11 at device 7.2 on pci0 usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0 usb0: USB revision 1.0 Thanks! -mi
