[BUG] Winbond USBDISPLAY ( 0416:5302) detected as 1280x480 but rendered as 240x320

[JyeroRayguster404]

What's happening?

TRCC Linux Bug Report — Winbond USBDISPLAY 0416:5302

Summary

TRCC correctly detects the Winbond USBDISPLAY device and repeatedly completes a HID Type-2 handshake with:

• VID:PID: 0416:5302
• Device: USBDISPLAY
• Firmware / bcdDevice: 0x0407
• Wire: HID
• PM: 128
• SUB: 1
• Reported resolution: 1280x480

However, the rendering pipeline later uses 240x320 for the same device. Frame transmission then fails immediately with:

short chunk write at offset 0
device.send returned False

The LCD does not update.

This appears to be a device-profile / resolution-mapping or HID Type-2 framebuffer compatibility problem rather than a basic USB detection or permission problem.

Environment

• OS: Ubuntu 26.04 LTS
• Kernel: 7.0.0-29-generic
• TRCC: 9.9.5
• Python: 3.14.4
• Architecture: x86_64
• Python implementation: CPython
• GPU: NVIDIA, NVML initialized
• Device: Winbond 0416:5302 USBDISPLAY
• bcdDevice / firmware: 0x0407

Device Detection

TRCC detects one device:

0416:5302 USBDISPLAY wire=hid

The diagnostic report initially reports:

handshake: PM=128 SUB=1 fbl=128 resolution=1280x480

The log also contains multiple successful handshakes:

HidLcd handshake OK: PM=128 SUB=1 resolution=(1280, 480) (type 2)

This occurs repeatedly, including during diagnostic probing.

Important Resolution Inconsistency

Although the device handshake reports 1280x480, the rendering pipeline uses:

DisplayService.build_frame: visual=240x320

The Qt renderer then creates:

create_surface: 240x320

The preview also reports:

preview.set_image: 240x320 -> widget 240x320

Therefore the device is detected as a 1280x480 display during handshake, but TRCC renders the framebuffer as 240x320.

There is also one earlier handshake entry reporting:

PM=0 SUB=0 resolution=(240, 320) (type 2)

but subsequent diagnostic probes consistently return PM=128 SUB=1 resolution=1280x480.

Frame Transmission Failure

When TRCC attempts to send the rendered frame, the log shows:

HidLcd 0416:5302 (type 2): sending 154112-byte packet

followed immediately by:

short chunk write at offset 0

device.send returned False (frame)

frame write returned False

0416:5302 write returned False

This happens repeatedly.

Even a solid black frame produces the same failure:

build_solid_color_frame ... 240x320

followed by:

short chunk write at offset 0

device.send returned False

Sensors / System Health

TRCC itself is otherwise functioning:

• Device detection: OK
• Sensor enumeration: OK
• NVIDIA NVML: OK
• PySide6: OK
• FFmpeg: OK
• 7z: OK

The health report shows only one warning:

udev-rules: No TRCC udev rules found under /etc/udev/rules.d/

The report suggests trcc system setup, but USB access is already working and the device can be detected and opened.

Expected Behavior

The device should be treated according to the successful HID Type-2 handshake:

PM=128
SUB=1
resolution=1280x480

The rendered framebuffer should match the actual device profile and be transmitted successfully.

Actual Behavior

1. Device is detected.
2. HID Type-2 handshake succeeds.
3. Device reports 1280x480.
4. TRCC rendering switches to 240x320.
5. TRCC generates a 240x320 framebuffer.
6. HID frame write fails at offset 0.
7. LCD does not update.

Request

Could you please check whether the 0416:5302 / firmware 0x0407 device profile is being mapped incorrectly?

In particular, please check:

1. Why the successful handshake reports 1280x480 but DisplayService.build_frame() uses 240x320.
2. Whether PM=128 / SUB=1 / fbl=128 has a dedicated HID Type-2 profile that should use 1280x480.
3. Whether the framebuffer packet format / packet length for this device is different from the generic Type-2 240x320 profile.
4. Why _write_frame() receives a short write at offset 0 even though device detection and handshake succeed.

Key Log Evidence

Successful handshake:

HidLcd handshake OK: PM=128 SUB=1 resolution=(1280, 480) (type 2)

Incorrect rendering size:

DisplayService.build_frame: ... visual=240x320

Frame transmission:

HidLcd 0416:5302 (type 2): sending 154112-byte packet

Failure:

short chunk write at offset 0
device.send returned False
frame write returned False

Thank you.

Device (model + USB ID if you know it)

Thermaright Trofeo Vision (0416 : 5302)

Steps to reproduce (optional)

1. Connect the Thermaltake Trofeo Vison 6.86" LCD via USB.
2. RUN 'trcc detect' and confirm the device is detected as 0416: 5302.
3. Load or create a theme and try to send it to the Lcd.
4. The GUI works, but the LCD remains on the factory/default screen.
5. The log shows framebuffer write failures, including "short chunk write at offset 0" and "device.send returned False".

Before submitting

• I'm on the latest version (pip install --upgrade trcc-linux, or the latest installer)
• I pasted my trcc report above — or my install/launch error if it won't run

Hi, just wanted to confirm same bug here. I'm trying to use my Trofeo Vision lcd on my raspberrypi 5 8GB - and it always want's to use wrong 320x240 res on it resulting in failure. Command "trcc detect" shows wrong info propably relying on wrong presets for the screen? Just guessing here.

trcc detect
1 device(s) found:
  0416:5302  Winbond USBDISPLAY  (wire=hid, resolution=240×320)

trcc system hid-debug 0416:5302 command shows correct info:

trcc system hid-debug 0416:5302
HID/LCD diagnostic for 0416:5302
============================================================
Handshake: Connected: (1280, 480)
  resolution: 1280x480
  model_id:   128
  sub_byte:   1

Persisted state:
  orientation:     0
  brightness:      100%
  current_theme:   /home/kamo/.trcc/data/theme240320/Theme1
  overlay_enabled: True

============================================================
Copy the output above into a GitHub issue.

Changing path in trcc.json file results with this file being overwritten by trcc-lcd app and defaults back to "/home/kamo/.trcc/data/theme240320/Theme1" folder. That is resulting with:

This plugin does not support raise()

In addition i can confirm that sending colors or pictures works just fine:

trcc display color 0416:5302 "#ff0000"

Hi @JyeroRayguster404, and @kamolot2k — thank you both. Two separate things here, and one of them is fixed.

Your main problem is fixed in v9.9.6. You spotted it exactly: the handshake reports PM=128 SUB=1 → 1280×480, then the rendering pipeline uses 240×320, and the send fails with short chunk write at offset 0. TRCC was treating a firmware revision as if it identified the panel. Several different Thermalright coolers ship as 0416:5302 with firmware 4.07, and the only thing telling them apart is the PM byte — which the code path in question was skipping past. When your panel didn't answer instantly, TRCC took the silence as an answer and pinned a placeholder 240×320 geometry. A 1280×480 panel then had nothing it could correctly send.

It now asks, and a panel that answers is believed. If either of you worked around it by starting the app with the cooler unplugged, or by using trcc device connect, that's why those helped — both skip the scan that triggered it.

# Ubuntu / Debian
wget -c https://github.com/Lexonight1/thermalright-trcc-linux/releases/download/v9.9.7/trcc-linux_9.9.7-1_all.deb && sudo apt install ./trcc-linux_9.9.7-1_all.deb

@kamolot2k — your second observation is a real, separate bug, and it is NOT fixed yet. You wrote that trcc detect shows the wrong resolution and guessed it was "relying on wrong presets for the screen." You were right, and it's worth saying plainly because you diagnosed our own output correctly:

trcc detect  →  0416:5302  Winbond USBDISPLAY  (resolution=240×320)
trcc system hid-debug  →  Connected: (1280, 480)

trcc detect prints a value from a static table and never asks the device. For a USB ID that covers a dozen different panels — from 240×320 up to 1280×480 — that number is a guess presented as a measurement. I've confirmed it still does this on the current code.

It should say "unknown" rather than invent one, and I have that queued. It's cosmetic in the sense that it doesn't affect what's displayed — but it sent you down the wrong path, which is exactly the harm a misleading diagnostic does.

Your persisted theme folder pointing at theme240320 is downstream of the same guess; once the panel is identified correctly, that should follow.

Would you both upgrade and let me know whether the display works? And @kamolot2k, if trcc detect still bothers you afterwards, that's the known-open half — not a new problem.

I can confirm that upgrading to 9.9.8 fixed the issue and my screen is working now. Great job.
