Absolutely. That's the intent. gphoto2 uses libusb to communicate with USB digital still cameras. > TOC reading is working, but if I like to read Thumbnails > I get some severe error : "uhci.c: d400: host system error, PCI problems?" This typically indicates you passed an invalid buffer.

Those will be always there, but if it's just for testing, I guess it wouldn't matter if they are there in the future. > Are there any further documentations ? > these one do I have already: > - lkmpg > - usb.cs.tum.edu/usbdoc (2000/12/25 (quite old ?)) http://usb.cs.tum.edu/usbdoc/ is the best text documentation. The sources would be better documentation :) JE _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
