usb in Kernel 2.6.[35]
I recently installed Kernel-2.6.5. In Kernel 2.4.24 I was able to transfer pictures from my ditical camera by gphoto2 (using the usermap in /etc/hotplug/usb and setting things up so that members of usbcamera could use gphoto2 to transfer pics from the USB camera). The module being used for this was usb-uhci. In kernels 2.6.5 and 2.6.3 though, I am not able to transfer the pics anymore. gphoto2 doesn't see any camera. Also, I see that there is no usb-uhci module loaded anymore. Only uhci-hcd (IIRC) and usbcore and ehci-hcd. What am I missing here? Where can I find documentation that explains this.

I don't know why your camera isn't working any more, but I can help with the modules questions: to my knowledge, usb-uhci has simply been renamed to uhci-hcd. The ehci-hcd module is for USB 2.0 support; USB 2.0 controllers apparently generally have companion controllers which are UHCI or OHCI, so you get both modules.

So, theoritically, I only need ehci-hcd to use USB 1.0 devices? And uhci-hdc or ohci-hcd if I want to use USB 2.0 devices as well? BTW, I also noticed that there is a usbcore module that uses uhci-hcd in 2.6.5 kernel. -HS -- (Remove all underscores,_if any_, from my email address to get the correct one.
