Subject: [PATCH] Record PCAN driver install status on mikkeli-orin-nano

The original report was written on another host. On this machine the
pcan module (NETDEV_SUPPORT) is built, installed under misc/, and loaded
at boot via /etc/modules; the adapter was not yet plugged in. Adds the
verification and post-kernel-update rebuild steps.

 ## Cleanup
 
 Source files left at `/tmp/peak-linux-driver-9.2.0/` and `/tmp/pcan-driver.tar.gz`. Can be removed after verifying everything works.

+## Current Status — 2026-08-05
+
+This report was written during an earlier session. On this machine (hostname: `mikkeli-orin-nano`,
+kernel `5.15.148-tegra`, L4T 36.4.4) the driver has been **built and installed**:
+
+| Step | Status |
+|------|--------|
+| Download PEAK Linux Driver 9.2.0 | Done (source at `/tmp/peak-linux-driver-9.2.0/`) |
+| Build with `NET=NETDEV_SUPPORT` | Done — module compiled successfully |
+| Install to `/lib/modules/.../misc/pcan.ko` | Done |
+| `depmod 5.15.148-tegra` | Done |
+| `modprobe pcan` | Done — module loaded (`lsmod | grep pcan` confirms) |
+| Boot persistence (`/etc/modules`) | Done — `pcan` added to `/etc/modules` |
+
+**Device not yet physically connected.** The USB adapter (`0c72:000c`) will be auto-detected and
+a `canX` interface created when plugged in. No udev rule is needed since the module loads at boot
+and the kernel matches the USB VID/PID against the module's built-in aliases.
+
+### Verification (after plugging in the device)
+
+```bash
+# Confirm module is loaded
+lsmod | grep pcan
+
+# Check for new CAN interface
+ip link show type can
+
+# Bring it up at 500 kbps
+sudo ip link set canX up type can bitrate 500000
+
+# Read traffic
+sudo candump canX
+```
+
+### After a kernel update
+
+This is an out-of-tree module. Rebuild with:
+
+```bash
+cd /tmp/peak-linux-driver-9.2.0/driver
+make clean
+make NET=NETDEV_SUPPORT all
+sudo cp pcan.ko /lib/modules/$(uname -r)/misc/pcan.ko
+sudo depmod
+sudo modprobe pcan
+```
