endoscope based on Pixart 2900 device does not work

polbrian · August 3, 2012, 2:05pm

I bought a Voltcraft BS-15 endoscope on the basis that it was supported by Linux, and should work out of the box, but it doesn’t, and I have found no clues in the web.
Device
Voltcraft defines the device as 640x480 30fps 24 bit RGB, AVI video, USB 1.1
Once plugged

Bus 001 Device 006: ID 093a:2900 Pixart Imaging, Inc.

The device is listed in Linux UVC driver & tools as supported by UVC with a discrepancy as the name listed is Agama V-315.

i probably can’t help, but while you are waiting for a real guru with
help, you might entertain yourself with:

did the device come with instructions and software? (a quick look via
google i find “Software CD”, “software easy to install”, and “User
manual” included in the sales) perhaps you have linux software to load…

OR, maybe the provided Window’s works fine if in WINE…

or, perhaps if you got that “works out of the box…with linux”
guarantee in writing, you will have no trouble returning it…

or, maybe you have to make a new udev rule (i sure can’t help with that)…

last: i can’t connect to the forums <http://paste.opensuse.org/71648095>
to see if you are new here, or not: if you are: WELCOME and sorry i
can’t be more help…

if not new: still sorry i can’t help more!!

Voltcraft are not helpful to non-MS users.
My trouble may stem from ignorance (had to install or configure something and didn’t), otherwise there is a bug… at least in
http://en.opensuse.org/HCL:Web_cameras
as I dutifully got the device ID from lsusb and found it in Linux UVC driver & tools

Some progress.
After trying, unsuccessfully, to access the hardware through wine and the installation software for windows, and a number of plug-unplugging from various usb ports, I succeeded streaming, though only in 160x120:

As a conclusion,

The documentation says that the endoscope supports USB 1.1; that sets the maximum transfer rate to 12,000,000 bps.
hwinfo reports this USB version and transfer rate for the device.
The better resolution of the set that uses no more than this rate at 30 fps is 160x120 (raw data, 8bits per pixel single CCD).

Somehow Windows software must negociate a transfer rate of 73,728,000 bps to get a 640x480 30 fps picture.

Is there a way to have Linux do the same?

I am not experienced in it . But I suggest that you can get help from web. Endoscope that are based on usb 1.1 is well worked.

If you have this type type problem then you firstly check that it’s a hardware or software problem. I haven’t well knowledge about this . You also get help from web and any other endoscope repair expert.
