Thread 'main' panicked when trying to display a greyscale image

Trying out the LED modules and I get an issue when trying to show a greyscale image and I don't know if I'm encountering a bug or just being an idiot. It happens with both my own image and the examples found in this repo ("/res/greyscale.gif", "/res/stripe.gif", and "/res/stripe.png").
With RUST_BACKTRACE=full set I get the following:

$ ./Downloads/inputmodule-control_cli_linux led-matrix --image-gray ~/Pictures/greyscale.gif 

thread 'main' panicked at 'Write failed!: Custom { kind: TimedOut, error: "Operation timed out" }', inputmodule-control/src/inputmodule.rs:430:10

I am running Linux Mint 21.3, which I know isn't officially supported, but being based on Ubuntu Jammy I didn't think it would be a vast departure. Everything else I've tried works, including --image-bw, so I'm hoping the problem isn't with my machine.

Same problem here
display_gray_image_cmd uses the SendCol for every column but after a few calls, it seems to panic with the time out error

Sleeping after each command sent would "fix" this, but I don't understand why sending few columns of data in a row is too much to handle

I was trying to create a black and white video playback feature by using the SendCol and CommitCols commands, but after about 5 or 6 of these commands invoked in a row, it times out and panics. Sleeping between the commands sent would let me get somewhere, but the video fps can't go above 10 because of this

I thought the USB 2.0 connection is the limit, but I guess its not?
What's going on with this?

I have the same problem on Ubuntu 22.04.

I encountered a similar error on Arch Linux when running inputmodule-control --serial-dev /dev/ttyACM0 led-matrix --all-brightnesses.

Here's what I did:

Install inputmodule-control from AUR
sudo udevadm control --reload && sudo udevadm trigger
RUST_BACKTRACE=full inputmodule-control --serial-dev /dev/ttyACM0 led-matrix --all-brightnesses

The error and stacktrace are:

Could you please make sure that you are on the latest firmware?
Does inputmodule-control --serial-dev /dev/ttyACM0 led-matrix --version work?

Weird enough, it also panics the first time I run that command
Second time the device actually turns on and reports back: Device Version: 0.2.0

Firmware is already at the latest

@Eddio0141

Similar or identical to what @Eddio0141 reports, I get this when running inputmodule-control --serial-dev /dev/ttyACM0 led-matrix --version for the first time:

thread 'main' panicked at inputmodule-control/src/inputmodule.rs:352:10:
Found no data!: Custom { kind: TimedOut, error: "Operation timed out" }

Running the same command again produces:

Device Version: 0.2.0

According to fwupdmgr there are no firmware updates available for Framework 16.

Thanks for looking into this.

Interestingly I get the same results - panic and then the actual version when I run a second time - but I can't get it to happen again. Re booting, removing the modules and putting them in again, it just returns the version.

Relevant output is
