The usb-serial adapter to sata is still a usb2 device.

I think the "what it is" part is a red herring.
Might not be though.

The machine is running out of resources
(am thinking it cant r/w as fast as it wants) so processes
stack up and some can crash.

bcm283x_dwc is in /usr/src/sys/arm/broadcom/bcm2835/bcm283x_dwc_fdt.c
and appears to be "DWC OTG 2.0 integrated USB controller" which maybe
has something to do with your setup.

Right now, am building current nodebug kernel from
stable/15-n282698-4311217a039c GENERIC arm 1500506 1500506
