Hmm, you don't have CONFIG_PRINTK_TIME enabled, so we don't know how much time elapsed between the disconnect and anything else. > Below is the complete usb debug when plugging the camsport. > > This is working well on Mac OS X (same laptop, same usb port), and I even tested > it on Windows on other computers, it is always working (recognized as a usb > storage). > On every recent linux I tested (ubuntu, gentoo, etc.), this hardware does not > work. > > Any hints? As you say, the camera disconnects itself. Who knows why? You might find it works better if you decrease the usb-storage scanning delay. Add a line saying options usb-storage delay_use=0 to your /etc/modprobe.conf (or /etc/modprobe.d/local.conf, as the case may be).
