I applied these patches on a clean 2.6.7 tree. With these patches the camera is sometimes recognized by Linux. It does not allways work. Below is a example where Linux recognized the camera on the 4th attempt. After that I can start to copy files. Coping files seems to work fine as long as I dont issue any dmesg commands. It has happend to me twice when I run tests with these patches that exactly when I issue a dmesg command the file copy fails. See the debug messages below. It does not fail allways when I issue dmesg commands. It works mostly. I estimate it fails on 1 of 20 dmesg commands (based on my very limited testing so far). The kernel I used has USB_STORAGE_DEBUG=n. Let me know if it would be interesting to try with USB_STORAGE_DEBUG=y.
