Please test usb-pwc-re-20061023.042702-r1 (just committed a hopefully last change) and mark it stable for 2.6.19 - older versions definitely break with it.
No we don't since we don't have any stable...
ditto
I don't have such a camera any more, but the module builds and loads correctly. so marked stable on ppc64.
x86 stable
amd64 stable
