A PS: to this one, clues if you will, to be added to the other info I've posted regarding a ClickSmart 310 camera, and the qcam-vc drivers.
I built a kernel with usb debugging turned on, which made it work. I'd also tried to build v4l into the kernel but that got an error exit, so I went back to making it as a module. So with everything V4L related is as modules below.
The difference between the verbose usb debugging on/off apparently does something to the timeing. With the debugging on, it works but the dmesg buffer is overrun so I don't get a full report only the tail end, and with the debugging turned back off and the kernel rebuilt, no other changes, then it fails, with these lines being logged in /var/log/dmesg: -------- vid 0x04B8 pid 0x0005 host/usb-uhci.c: interrupt, status 2, frame# 1641 hub.c: usb_hub_port_status (2) failed (err = -84) hub.c: connect-debounce failed, port 3 disabled --------
And the device is not intitialized.
Is this a usefull clue?
