A Picture where we could see:
- The FULL Part Number (is that a 2 or 8 or what between 33 and 00 ?)
- The Part in Question (Picture from the opposite Side)

I would have thought one small Solar Busbar if I were to throw a wild Guess but hey that's the Info I can gather from this Picture :p

I finally managed to fix my Script to do that.

But, even though I am writing the correct Serial Number, it still "Falls back" to 534d:2130 MacroSilicon USB Video (instead of Bus 004 Device 003: ID 345f:2130 UltraSemi USB3 Video with Stock Firmware).

Serial on the Patched Firmware shows 20201228 which is nowhere to be seen in the File from HxD :rolleyes: .

Something weird is going on ...

who tells you that serial ?
Click to expand...
lsusb -d 534d:2130 -vvv | grep -i serial

But I still don't understand why the VendorID changes after changing ANYTHING. Do they have some kind of CRC/Checksum and if that fails, they load a Fallback Image or something ?

i found a checksum
area from 0x30 (exclude header)
to 0xFBCF = lenght 0xFBA0

I received this with my 12-board package, so I was hoping someone from you guys will know :)

I'm also wondering if it's an OEM (Ultrasemi) that's doing a bit of a Special Firmware compared to Stock Macrosilicon Firmware.

I also read on some GitHub Repository that they changed the Firmware Version at some Point and the old one was somewhat better.

What Checksum algorithm is that they used ?

I could also try to find an old Firmware directly from Macrosilicon (there were some Files available on the Internet, but I didn't feel comfortable downloading some Files from some Russian linked Website ...) and flash that instead. Problem is finding something that looks and is legit though ...

EDIT 1: the Discussion on GitHub I was referring to might be this one

written in nice letters on the left of the checksum (screenshot results)
checksum-16
add all bytes to a 16 bit result,
Click to expand...
So that would explain why it's falling back to some sort of stock Firmware, the CRC mismatches.

EDIT 1: @RolloZ170 is the 25 F7 (just before the Checksum itself) to be included in the Checksum Calculation ? Or what is it otherwise ?

if not selected, not included in checksum-16
the two bytes are same in both files and some other meaning.

Thank you @RolloZ170.

I was getting crazy until I remembered that Python indexing for List Slices need to have a +1 for the End Index (otherwise it's NOT included).

After that, I could verify the same Result as the Stock Firmware.

And a few Bug Fixes later for the same List Slice Issue, I wrote the new Checksum after altering the Firmware :D .

Code: 
# After Flashing but BEFORE disconnecting & reconnecting Adapter
root@HOST:/home/user# lsusb -d 345f:2130 -vvv | grep -i serial
  iSerial                 3 20210623

# After Flashing and AFTER Disconnecting & reconnecting Adapter
root@HOST:/home/user# lsusb -d 345f:2130 -vvv | grep -i serial
  iSerial                 3 OJJOTYI1
A bit of a Bummer that it supports only 8 Characters (one of the Repositories that I linked claimed it supported up to 31 Characters) but maybe that's the difference between UTF-8 and UTF-16 where we have 1 WORD (1 Hex Value, 2 Bytes) set to 0x00 in between each Word.

For Reference this is what I ran with:
Code: 
sudo ./configure.py --executable=./ms-tools/cli/cli --serial=OJJOTYI1T3WQSS05 --log-level=0 --no-backup --file ms2130.modified.flash.2025-05-30-07-08-35.bin

EDIT 2:
Explanation:
  • --executable tells where to find ms-tools Executable for cli
  • --serial is to set a custom Serial Number (useful if you want something Specific AND/OR if you need to run the Script several Times because there were some Errors
  • --log-level=0 suppress all output from ms-tools Executable
  • --no-backup do NOT backup the current (stock) Firmware, useful if you run this Script several Times and do NOT want to wait a couple Minutes each Time
  • --file is to use a custom File to calculate the Checksum (only useful if you have a CORRECT File with the new Serial Number already present, otherwise do NOT use this Parameter !)

The only "Minor" Problem is that the only Thing I get as Capture is a black Screen ...

EDIT 1: also my MS2309 seems to be affected, so it's maybe more Linux Kernel Update or maybe ffmpeg related or something (it also affects 2 PCs, both running Ubuntu).

EDIT 2: Changed VGA to HDMI Adapter, changed Power Supply Cable. No change. Now I changed HDMI Cable and it works. So maybe HDMI Cable was faulty/broken/twisted/etc :( .

@dbram I thought I would ask before embarking on some parallel Work & reinventing the Wheel :D .

Can you share the Image/Build Script/Configuration for the PiKVM on a GitHub (or GitLab I guess) Repository ?

I'd like to try to see first of all if my "Concept" to rename USB Devices Works.

ffplay (and apparently ffmpeg in General) does NOT work nicely with Symlinks.

On the other Hand, guvcview seems to work fine with Symlinks.

This works as a normal User (without sudo / root Access):

user@HOST:/$ /usr/bin/ffplay -fflags nobuffer -input_format mjpeg -video_size 1280x720 -framerate 60 -color_range pc /dev/video0

user@HOST:/$ guvcview --device=/dev/video0

user@HOST:/$ guvcview --device=/dev/ms2130-pc01-video0

This does NOT work, not even with root / sudo access:
Code: 
user@HOST:/$ /usr/bin/ffplay -fflags nobuffer -input_format mjpeg -video_size 1280x720 -framerate 60 -color_range pc /dev/ms2130-pc01-video0

That was configured as a UDEV Rule (after several Attempts I think I found the one that worked, see last Line - 1) in /etc/udev/rules.d/99-ms2130.rules:
Code: 
# First HDMI Capture Device
# SUBSYSTEM=="video4linux", ATTRS{serial}=="SXEFK471", NAME="/dev/video/ms2130-pc01"
# SUBSYSTEM=="video4linux", ATTRS{idVendor}=="345f", ATTRS{idProduct}=="2130", ATTRS{serial}=="SXEFK471", NAME="/dev/video/ms2130-pc01", ACTION=="add"
# SUBSYSTEM=="video4linux", ATTRS{idVendor}=="345f", ATTRS{idProduct}=="2130", ATTRS{serial}=="SXEFK471", NAME="ms2130-pc01"
# SUBSYSTEM=="video4linux", ATTRS{idVendor}=="345f", ATTRS{idProduct}=="2130", ATTRS{serial}=="SXEFK471", SYMLINK+="ms2130-pc01"
# SUBSYSTEM=="video4linux", ATTR{name}=="USB3 Video: USB3 Video", ATTRS{idVendor}=="345f", ATTRS{idProduct}=="2130", ATTRS{serial}=="SXEFK471", ENV{ID_V4L_CAPABILITIES}==":capture:", GROUP="video", SYMLINK+="ms2130-pc01"
SUBSYSTEM=="video4linux", ATTR{index}=="0", ATTR{name}=="USB3 Video: USB3 Video", ATTRS{idVendor}=="345f", ATTRS{idProduct}=="2130", ATTRS{serial}=="SXEFK471", ENV{ID_V4L_CAPABILITIES}==":capture:", GROUP="video", SYMLINK+="ms2130-pc01-video0"
SUBSYSTEM=="video4linux", ATTR{index}=="1", ATTR{name}=="USB3 Video: USB3 Video", ATTRS{idVendor}=="345f", ATTRS{idProduct}=="2130", ATTRS{serial}=="SXEFK471", ENV{ID_V4L_CAPABILITIES}==":capture:", GROUP="video", SYMLINK+="ms2130-pc01-video1"
Only the one with ATTR{index}==0 works strangely enough though, even though /dev/video1 also exists.

This shouldn't be a huge problem with Containers, as I can probably just do a small Python Script to write Podman Quadlets and replace the /dev/ms2310-pcX-video0 Symlink with the Target (/dev/videoY) at startup. But it would still be nice to avoid that extra Work if I can help it :D.

@luckylinux , I haven’t decided if and how to put this opensource (yet).

When I tried ffmpeg or ffplay directly it was quite (cpu) resource intensive.

I’ve been using ustreamer from the pikvm project and this is very low on resource consumption, I believe when specifying the right hardware encoding on the usb capture stick. For the Id I’m just using /dev/video0 if I’m not mistaken.

will double check later on.

Well I gave it a try on a RockPro64 SBC I had laying around (with /dev/video4 AKA NOT renamed, need to put a 10k Resistor on this SBC because it will NOT handle Reboots otherwise [apparently]).

So ustreamer Docker Image worked fine with Podman Rootless (although so far I am running with several Options that might not be needed in order to allow more Lax Permissions) once I let it run using Exec (Command) Mode. Undeed switching to MJPEG Format dropped the CPU Usage quite a bit (although I will NOT be able to handle more than 4 Streams on this SBC).

I believe an Intel Xeon/i5 or AMD Zen APU with integrated Graphics will probably fair much better.

Documentation was VERY lacking on the Docker Options, Command Line Options is as simple as listing them with podman exec -it kvm-test-01 /ustreamer/ustreamer --help.

Now I have to Catch up on how to deploy the Rest of the Components via Containers (kvmd as well as the "main" Server ?) plus of course the HID Device which I probably will also use the esp32-s3.

EDIT 1: Podman AddDevice= Directive in Quadlets (equivalent to --device in Command Line) will actually resolve Symlinks for you, so you only need to add this to get renamed USB Capture Device available in the Container:

Code: 
AddDevice=/dev/ms2130-pc01-video0:/dev/ms2130-pc01-video0
