### Checklist

Please fill out this checklist as items are completed. Link to PRs and issues as appropriate.
- [ ] Check if existing test covers most or all of this testpoint (if so, either extend said test to cover all points, or skip the next 3 checkboxes)
- [ ] Device-side (C) component developed
- [ ] Bazel build rules developed
- [ ] Host-side component developed
- [ ] HJSON test plan updated with test name (so it shows up in the dashboard)
- [ ] Test added to dvsim nightly regression (and passing at time of checking)
- [ ] For SiVal test cases, test is running relevant FPGA or silicon regression

NOTE: This is expected to fail on ES but is required for Prod; should be SV4.

Start with the chip_sw_usbdev_toggle_restore test point and review the checklist to determine which device-side, Bazel, test-plan, and regression pieces are missing. Confirm whether an existing test covers most of the test point, then verify completion through the relevant FPGA or silicon regression; the issue notes that it is required for Prod and expected to fail on ES.
