Thanks Martin,

So basically the same result. Now it is time to try and get some more information about what is going on. So I modified webcam.exe to do so when you specify an additional parameter.
With that parameter specified it will show some more debug information and it will create a webcam.bin file  containing video header data.

Just run webcam /* by itself and report back your results like you did before. Attach that webcam.bin file too.

Regards,
Wim

Hi Wim

I run webcam.exe /*

I'm attaching the console log and the bin file.
Just i detail I forgot to tell you before, the webcam.exe program keeps running, it does not quit automatically, I usually do the ctrl+c myself after a while of not reporting anything else on the console.

Thanks again Martin. This webcam actually contains both an "Integrated Camera" and an "Integrated IR Camera".
Scanning the USB descriptors by the webcam program resulted in setting up the "Integrated IR Camera" but no video data was obtained.
I suspect that by using webcam /m the "Integrated Camera" would be setup instead of the "Integrated IR Camera".

However I decided to change scanning the USB descriptors to always use the first camera rather than the last one.
So please test again with this version using webcam /* and report back like you did before.

Wim

Appears that ObtainThread is working alright in so far that it scheduled all eight UsbStartIsoTransfer()s. Still error code [0000280] which means timeout error.

Perhaps the 3 seconds timeout value is just too short. Therefore I now changed it to wait forever. Please test and report again.

Wim

Thanks Wim

The camera keeps the lights up, but I get no image on vmvideo.exe (no parameters).
I'm attaching the log.

Thanks Martin,

After scheduling all eight UsbStartIsoTransfer(s) the ObtainThread now awaits forever signalling of their completion by the USB Host Controller Driver.
Apparently this signalling does not occur at all. Reason unknown. It seems to me that there is something wrong with the 12.14 USB Host Controller Driver.
Perhaps it is a good idea to plugin an external webcam to see whether or not  that webcam does indeed work well with the USB Host Controller Driver.

Hi Wim

Today I finally tried the "Logitech C920 HD Pro Webcam" that used to work on the past. The webcam camera lights up, but as you suspected I can not get video from it.

I tried the same "Logitech C920 HD Pro Webcam" on a Thinkpad L420, with USBUHCD 12.14 (USB 2.0) and the devices worked you webcam10.zip (from your website) and "webcam-test-20240101.zip ".

Maybe it is an issue with USB 3.x.

Hello.

Going back to the network adapter of this machine, I got the special cable adapter to connect the Ethernet cable.  (PN: SC10P42354). I checked the cable on Windows 11 and it worked.

When I installed ArcaOS 5.1 it recognized the adapter with the E1000B driver.
It has the following HardwareID, 8086:0D4E which is listed on Arca Noae website.

But, I can not get network and I'm not good with Network troubleshooting. On boot, the device driver E1000B.OS2 (1.1.8 ) does not report any problem. The lights of the cable light up. But on the T14s I get no IP or DNS, so no ping.  On "NetWork adapters and Protocols" I have the E1000B driver and IBM TCPIP (0). Nothing else.

ping to 127.0.0.1 replies "no route to host".

What do you suggest me to troubleshoot this Ethernet adapter  and TCPIP ?

Hello.

On "DDNS Configuration" I get a "(MSG04) Configuration failed: DHCP client is not running" error.

So I run C:\MTPN\BIN\setup.cmd and it restarted the DHCP server and I got IP !!!!!
Seems that "DHCPSTRT -i lan0 -d 0 " did the trick.

DHCP client won't start again on my next boot, I need to find out how to turn it on in the config.sys.
