[RM comments: Original poster had a USB-connected Sony DSC-W1 digital camera, which generates signs of USB-device recognition at the hardware level (a beep or two and some hard drive activity), but no signs of software support. James calls attention to a kernel header file in which USB device signatures are encoded, which may need re-editing for previously unknown USB devices.

The file in question is billed as the "Driver for USB Mass Storage compliant devices / Ununsual [sic] Devices File".

I'm having similiar problems with a DSC-P100. The best info I can gather implies that I need to put hotplug into verbose mode in order to discern the vendor/device major/minor numbers, add these to [linux]/drivers/usb/storage/unusual_devs.h, and then recompile/install the new kernel.

Seems odd, to me, to have to edit static/kernel files in order to add new device support. As such, I'm looking for a better way. I'm thinking about getting a generic card reader and just using it, but, given that the camera has USB, I'd prefer using it directly.
