Hardware testing: Linux x64 + LS-5000 (USB)

[rohanpandula]

Linux x64 preview packages (AppImage + portable tar.gz) are built and package-tested in CI, but nobody has driven a real LS-5000 from them yet. The bridge uses libusb + SANE on Linux, so distro and permission differences are exactly what needs field data.

Today

1. Plug in and power on the scanner, then:

lsusb | grep -i 04b0

Expected: a line with 04b0:4002. If nothing appears, that alone is a useful report.

2. Deeper check with the nkscan CLI (a separate open-source Coolscan driver; read-only with --list): download nkscan-x86_64-unknown-linux-gnu from the nkscan releases page, then:

chmod +x nkscan-x86_64-unknown-linux-gnu && ./nkscan-x86_64-unknown-linux-gnu --list

If you get a USB permission error, retry with sudo and say you needed it — that is precisely the udev data point this issue is collecting.

3. Comment with your distro, kernel (uname -r), desktop environment, and both outputs.

When the previews ship (v0.3.0-beta.2)

1. Download the AppImage from the releases page, chmod +x it, run it.
2. Connect, preview, scan a frame.
3. Report exactly where it stopped and paste the in-app error report. A working udev rule for your distro is a contribution in itself.

Stay nearby while testing — the scanner moves film.

You are helping me test Nikon LS-5000 support on Linux x64 for ScanStudio (open-source
scanning app). Walk me through, adapting to my distro:

1. Scanner on and plugged in: run `lsusb | grep -i 04b0` (expect 04b0:4002).
2. Download nkscan-x86_64-unknown-linux-gnu from
   https://github.com/activexray/nkscan/releases/latest, `chmod +x` it, run it with
   `--list` (read-only — it only enumerates). If USB permission is denied, retry with
   sudo and note that we needed it.
3. Check https://github.com/rohanpandula/ScanStudio/releases/latest for a Linux
   AppImage. If present: run it, connect, preview, scan one frame — I will stay at the
   machine, the scanner moves film — and if anything fails, have me copy the in-app
   error report. If absent, stop after step 2.

Run only the commands above or direct equivalents. Collect full outputs.

Then draft a comment for https://github.com/rohanpandula/ScanStudio/issues/25 with —
Setup (distro, kernel from `uname -r`, desktop), Steps completed, Outputs (code
blocks, noting if sudo was needed), Result. Show me the draft and do not post without
my explicit approval; if you cannot post, format it so I can paste it myself.
