(USB_ERR_IOERROR, ignored) as the first failure of the sequence. This establishes that U-Boot is not the only thing to have problems with your equipment. I'll note that the: da0: <SABRENT 0214> Fixed Direct Access SPC-4 SCSI device da0: Serial Number DD564198838F9 does not match other log files: da0: <SABRENT 1214> Fixed Direct Access SPC-4 SCSI device da0: Serial Number 000000000000A but it may well be an example of garbage-in/garbage-out. The same goes for the usual: umass0: SCSI over Bulk-Only; quirks = 0x8100 vs. the 3 odd examples: umass0: SCSI over Bulk-Only; quirks = 0xc105 umass0: SCSI over Bulk-Only; quirks = 0xc105 umass0: SCSI over Bulk-Only; quirks = 0x8101 You also got another "0 Storage Device(s) found". It again has the sequence for portstatus: 311, 311, (sequence of 5 instanced of:) 301 for: Manufacturer Product U-Boot Root Hub SerialNumber bind node usb1@1 So, just like the others. === Mark Millard marklmi at yahoo.com
