On the -current Pi3 I see in part:
ugen1.4: <JMicron SABRENT> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
(500mA)
{
UE_CONTROL_OK : 83
UE_ISOCHRONOUS_OK : 0
UE_BULK_OK : 3730195
UE_INTERRUPT_OK : 0
UE_CONTROL_FAIL : 0
UE_ISOCHRONOUS_FAIL : 0
UE_BULK_FAIL : 61
UE_INTERRUPT_FAIL : 0
}
That's the USB3 hard disk boot drive. All other devices report zero bulk fails.

Nothing obviously amiss....if I'm looking at the right data.

On a whim, I checked a Pi4 running -current which also has a usb-sata boot
drive.
It reports UE_BULK_FAIL : 56 for the disk and performance seems good.
An old Pi2 running -current with a relatively old USB2-sata boot disk
reports zero bulk errors. No bulk errors seems desirable, but is some
non-zero error rate normal?
All three machines have been updated within a couple of days.
Thanks for writing!
