Identifying a webcam module

For reasons that are irrelevant here; I wish to specifically identify the webcam module that is built-into a recently purchased ‘Visulaliser’

My Mac mini discloses the information that should be sufficient to just ‘look it up’ but my Google-fu is fading

Can anyone advise, please ?

Camera ‘self-identifies’ on the Mac mini as:

d6fcg00271000a07:

Model ID: UVC Camera VendorID_3034 ProductID_22656

Unique ID: 0x21000000bda5880

USB ID Database give Vendor ID 3034 as Toshiba Visual solutions - now known (since 2021) as TVS REGAZA . Owned since 2017 by the Chinese Hisense group.

Nearest product I can ID is

TCD2566BFG | Linear Image Sensors | Toshiba Electronic Devices & Storage Corporation | Asia-English (semicon-storage.com)

Many thanks for that, Peter … I will have a look

Edit: __ definitely the wrong product, I’m sorry to say

Mine is allegedly an 8Mp camera, capable of 4K

They have a range

Color sensor | Toshiba Electronic Devices & Storage Corporation | Asia-English (semicon-storage.com)

but the device you have may be a prior generation and/or the device id you are seeing may be for the camera unit rather than the sensor chip.

Thanks again, Peter … much appreciated.

Edit: __ as all of those are line sensors, not camera-style arrays, I am beginning to wonder if there is some misreporting going-on. The camera behaves correctly as a typical UVC device, like almost any modern webcam but with better resolution than most.

The format of the Vendor and Product IDs looks a bit too short and simple. If they mean anything it probably only refers to the circuitry not the the chip itself. There are lots of 8Mp 4K cameras and modules out there based on Sony IMX sensors. To find out what is in there I think you might need to get your screw driver out and have a closer look. I did suspect it might have come from Realtek. You´re not losing your Google-Fu, it´s just difficult to find out without taking a can opener to it. There are whole lists of Mac compatible cameras out there but the ID´s don´t fit any i can see. Another complication is ,is the visualiser equiped with auto focus?

I agree.

On linux the go to command line utility for this is 'lsusb' and I see someone has written a version of it for Mac, installed with:

brew install mikhailai/misc/usbutils

Then try

lsusb --verbose

Other options described in the man page.

I expect Mac OS is the same as Linux in that an ordinary user may not have permission to see everything, in which case try:

sudo lsusb --verbose

It is “focus free” … in the sense that it is fixed-focus but has massive depth of field … which in turn implies that it is a very small sensor with a very short focal-length lens attached in the optimum position.

To all appearances the whole contraption is essentially a simple UVC webcam mounted [together with some LEDs] on a folding stick … it just happens to have been done rather well.

As a microscopist; the performance of some of these devices astonishes me.

In absolute terms the resolution is low, but the big-screen impact is ‘Wow!”

MichaelG.

brew install mikhailai/misc/usbutils

.

I might give that a go, Dave

If I don’t want to risk the Mac, I could dig-out the RasPi 4

Life is a bit complicated at the moment, so I was hoping someone just knew an easy way of tracing the IDs.

… but if they don’t look right to you guys, that may be impossible.

Thanks to all

MichaelG.

Sorry, the easy ways didn´t. There are quite a few modules out there which, particularly with your knowledge of microscopy optics, could probably be adapted to whatever you have in mind..

Best Wishes,

I fell at the first hurdle

zsh: command not found: brew

… so what, aside from basic competence, am I missing ?

MichaelG.

.

Edit: __ Reading this :

 https://setapp.com/how-to/install-homebrew-on-mac

makes me think that using the RasPi 4 might be easier and quicker.

[ UPDATE ]

We have something approximating progress

I have fired-up sudo lsusb --verbose on the RasPi_4 and it gives me masses of information … most of which I don’t understand.

Any advice regarding what to look-for would be welcome.

MichaelG.

Curiouser and Curiouser …

Having found that the Visualiser could be seen in lsub … I unplugged it from the RasPi and went back to playing with the Mac.

Chancing to look at ‘System Information’ again, I realised that it was still showing the same details for Camera … without the device being plugged-in. So I tried a little webcam, and nothing in the details changed !

I plugged the Visualiser in again, and still nothing changed.

So far as I am aware, there is no way of refreshing the ‘System Information’ display

… I thought it was supposed to change dynamically

I am was beginning to wonder if these details are were just some sort of ‘place-holder’

[ Before anyone asks … I am using Ventura on an M1 Mac mini ]

.

Edit: __ I have tried re-booting, and have also discovered how to refresh the information

… a more methodical investigation is required !

Oops … Wrong again … The answer should be Yes

I have just observed it auto-focussing

MichaelG.

My bad, I assumed brew was a standard install on Apple and it's not. It comes with the 'Homebrew' package, which has to be installed first with, cut and paste:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

lsusb should always give a recognisable name from the Vendor ID, but what comes back from the Product ID depends on the supplier. Worth trying lsusb on both Raspberry and Apple in case one is more up-to-date.

lsusb on my Ubuntu system has both terse and informative examples:

Bus 002 Device 002: ID 05e3:0612 Genesys Logic, Inc. Hub
Bus 001 Device 012: ID 10d6:1101 Actions Semiconductor Co., Ltd D-Wave 2GB MP4 Player / AK1025 MP3/MP4 Player

You can narrow the query to a particular device with:

lsusb -d 10d6:1101 --verbose

In the example 10d6 is the Vendor and 1101 is the Product. Try your camera's IDs.

Dave

Thanks, Dave

I remembered, from one of our previous discussions, that using brew involved a big download of X-Code stuff that I am never likely to use … the mini would handle it, but I don’t want to

It seemed much easier to set-up the RasPi [which I have been intending to do anyway]

After I have eaten, I will try narrowing the query as you suggest.

MichaelG.

In hexadecimal Vendor_ID3034 seems to be 0BDA and the Product_ID22656 is 0x5880.

The Vendor_ID points to Realtek, no luck with the product ID.

Dick.

That seems to be the case, Dick

… or have l got the syntax wrong ?

MichaelG.

Seems to fit, or what are the chances? The problem is I couldn´t track down the exact product. The Realtek site is chaotic or it is a special for one customer...

Google Realtek 5880 uvc. Seems to fit.
