View Full Version : [Solved] digital camera not detected via USB cable
October 24th, 2010, 04:03
I am having a problem where my Canon Powershot 630 is not detected when I plug it in to download images while running "mykernel". If I boot into kernel.GENERIC (8.1-R-p1, amd64) the camera is detected just fine. I re-compiled a kernel after un-commenting everything in the config's USB support and USB serial sections (except the double bulk pipe entry) but that kernel also fails to properly detect the camera. Is there anything *not* in the USB sections of config that pertains to USB devices? SCSI perhaps?
FWIW, I can mount flash drives without issue. It's just that dang camera that seems to need GENERIC.

device scbus # SCSI bus (required for SCSI)
device da # Direct Access (disks)
device pass # Passthrough device (direct SCSI access)
device uhci # UHCI PCI->USB interface
device ohci # OHCI PCI->USB interface
device ehci # EHCI PCI->USB interface (USB 2.0)
device usb # USB Bus (required)
device ugen # Generic

Indeed. AFIK _all_ externally plugged in storage on FreeBSD is through scbus and da. In any case, unless you really know for certain that you'll never use it (embedded devices, for instance) or you really desperately need to save a couple 100K in your root directory do not remove basic SCSI support from your kernel (people who enjoy pulling out their own hair excepted).

And, yes, it was SCSI. I had fat fingered a kernel config line with a comment. It's silly really. I have 4GB of RAM; no reason to trim configs anymore. Must be a habit held over from my 4.x days.
