Bandwidth means not enough cpu power or usb channel speed? It is the usb bandwidth. The host controller channel to the usb device does not have enough capacity for the requested video stream. The Bresser microscope asks for 8 times 3 times 1020 data bytes per microsecond. That is 24.480.000 bytes p...

Do you mean a window that shows the video from several cameras at the same time? This version please. That would be too much work. I am not going to do that. Sorry. After starting the first program plug in the second webcam and start the second program. But I am afraid that the first webcam will fr...

As you can see I am a coin collector. I use the scope to checkout success of coin cleaning. This is a candidate, not yet cleaned. Thank you Wilfried. :o I appreciate the sample chosen. I am impressed by the result. Keeps me motivated! By the way, what about the situation if I want to use more than ...

Hi Wilfried,

To show success I would appreciate to see a snapshot of a specimen under the Bresser microscope being posted here.

Wim.

It works fine with 1 cpu, with 2 cpus collecting freezes only, no difference. What did I miss? Hallo Wilfried, You missed nothing. I made a slight change in the order of taking a snapshot and refreshing the window which appeared to have no effect. Thanks for testing it out. I am done with it now. B...

UVCSCOPE: 640x480 on startup works fine. With both cpus active, the freeze problem persists. With /MAXCPU=1 (Thanks Sigurd) we've got it. No freeze anymore. Snapshot works fine also, nothing to do for PMVIEW PRO. ;) Thanks Wim, you made another USB-toy working for me!!! If you need more testing, yo...

I have created uvcscope.exe which uses more isochronous buffers. And it starts up maximized.

Hi Wim, thanks for your special support! Starting uvcview without parameters offers the best result. The camera shows more than 5 minutes video without freezing and without errormessage. After maximizing the window or taking a picture the window freezes and the known errormessage is shown. Picture ...

These are from the packages you mentioned on your homepage for using websee. Yes, right you are. I must say that I don't know what to do next. I could send my latest version of usbcalls.dll and usbresmg.sys for you to try out. I'll send it to your private email address that I have. I rather not pos...

Hi Wilfried, o.k. :) nice. Some video already. Ich glaube alle Requirements erfüllt und alle Installationsschritte durchgeführt zu haben When booting with camera plugged in, calling uvcview offers a black window and a trap 000d in USBEHCD 000F:E667 after closing the window. It is possible that you n...

Hallo Wilfried, It does not look too bad. It appears that you are using the 320x240 format at the highest possible bandwidth. This might be a combination that this camera does not like. There is a parameter that allows you to choose a lesser bandwidth setting. So please experiment a little. This par...

Wim, you said you don't have a ptp camera to test with. If you can actually use the camera i sent you. please keep it. I think I have found a solution to the low battery issue. NiZ batteries with a clammer tension of 1,6 volts. I have ordered a set. Let me know if you have an actual use for the cam...

Thanks, Wim. I'll ask Martin I if he'll put the changed sources on github and will see to it that the complete zips get uploaded to Netlabs and/or Hobbes with reference to usbres02.zip. Thanks to you too. I think we are done. I'll upload usbres02.zip to hobbes. Thanks also for letting me use your c...

Diver has recompiled ptpro with the required changes. A testversion is at ftp://guest:guest@guzzi.demon.nl/ptpro.exe
And camera,exe: ftp://guest:guest@guzzi.demon.nl/camera.exe

Both work over here with the usbres02.zip drivers.
Wim.

I see in the camusb.c line 629 source compared to the prpro.usb line 401 source this difference : cnr.length = CAMCNR_CALCSIZE(0); cnr.length = CAMCNR_CALCSIZE(1); Is this what needs to be changed in the CloseSession routine? Yes. I would replace line 401 with line 628 and line 402 with line 629 to...

Yes, with the "guzzi" set I just tested with camera.exe and that works! Will your fix be implemented in the Arca Noae set too? Now that "guzzi" works, you'll still have to test camera.exe with the usbres02.zip drivers to confirm that these work too. David Azarewicz is aware of &...

The real problem appears to be the 0x2006 error. It means PTP_RC_ParameterNotSupported.This error code has been defined in source file ptprocodes.h but I can't find where it is actually reported in the code. I must be blind. O.K. I turned the light on and I suddenly saw what happens. This error cod...

Hallo Guzzi, I don't know what the best way is to tackle the problem, but I decided to let you try out some intermediate versions first. There were some major changes that I implemented in steps. The version in guzzi8.zip is about halfway of these steps. If it does not work I'll go some more steps b...

To Guzzi, I am puzzled... Are you sure that your nikon d60 camera is set to ptp mode? Could you just try:

ptpro -d -v2

ptpro -l -v2

Hallo DonLucio and Guzzi,

3. PtPro110 does NOT work with the usbcalls.dll and usbresmg.sys from usbres01.

I have updated my Usb Resource Manager. Go to my website, download usbres02.zip and do the installation.

Both PrPro110 and Camera15 work here. Most likely Tame/2 will work too.

Regards, Wim.

Hallo Guzzi, I have sent the camera, you should have it in a day or two. Please save the packaging, I do want the camera back because I have found a solution for the low battery problem). I will of course pay for the postage. The camera arrived yesterday in good order. Thank you. I can right now con...

O.K. I'll do that,

Thank you for your offer. I will be testing with it in due course.
