Hello
I have strange problem with my book scanner. I last use it about 8 weeks ago and everything was ok. Today when I try to connect to cameras with TTC+CHDK there is a problem : "error: could not start the cameras". I don't instal nothing on this laptop during last few months - I use it only for scanning. I turn on cameras without problems, windows make sound that new devices is connected, windows see my both Canon A2500. I use windowsw 10 64bit ,
It is second time that after long break with using TTC I have this problem , last time I reinstall everyting (chdk on cameras, libusb,ttc ) and it solve the problem. But it take a lot of time to reinstal everything befor scanning.
It is possible that for example Avast block some drivers ?
Have somebody any sugestion ?

My best guess is that Windows update may in some unknown situations remove the LibUSB driver.

If that happens first try to only reinstall LibUSB for the camera(s). That solved it for me last time I had that kind of problem.
