Detailed Description

The endurance and benchmark member of the USB self-loop matrix. Same dual-stack image as usb_selftest_hs_host – HS host on J7, FS MSC device on J11, the loop cable between them, no PC involved – but the host worker repeats the 1 MiB MRAM integrity sweep back to back instead of once.

Every READ(10) burst is still memcmp'd against the real MRAM window, so a single corrupted or dropped transfer anywhere in the soak fails the run. Volume and elapsed time are summed across iterations for a throughput figure that is stable enough to compare between builds.

The read-only WRITE(10) rejection is confirmed once at the end: the write STALLs the bulk-OUT pipe, so it has to run last (#92).

hs_host proves one clean pass; this proves the transport stays byte-perfect under sustained load. k_selftest_soak_iters sets the soak length – bump it for a longer endurance run.

Pinout and VID/PID are identical to usb_selftest_hs_host. Bench use only.
