OK, this at least agrees with what i thought was happening.  from

all the useful stuff is near the very bottom, you can see the parts
of the 2nd to last successful transfer:

1698435122.516436 usbd_transfer#608@0: called: xfer = 0xc217fe78, flags = 0x2, pipe = 0xc3000100, running = 0

...
1698435122.516509 usbd_xfer_schedule_timeout#604@0: called: xfer 0xc217fe78 timeout 5000ms set 0 reset 0
1698435122.516515 usbd_transfer#608@0: <- sleeping on xfer 0xc217fe78

...
1698435122.516958 usb_transfer_complete#613@0: <- done xfer 0xc217fe78, wakeup

but the next one doesn't get this far:

1698435126.993608 usbd_transfer#609@0: called: xfer = 0xc217fe78, flags = 0x2, pipe = 0xc3000100, running = 0

1698435131.987617 usbd_xfer_timeout#1@0: called: xfer 0xc217fe78 status 1

but here it should complete with failure but the next logs are:

1698435131.987621 usbd_xfer_probe_timeout#1@0: called: xfer 0xc217fe78 timeout 5000ms set 1 reset 0

1698435131.987679 ehci_sync_hc#8@0: cmd = 0x00020071 sts = 0x0000c008

there's no completion event here, even though it timed out.  Taylor,
any ideas off hand?
