Sorry for replying to my own post, but upon further investigation, it appears that perhaps the usb-storage module doesn't have the correct matching pattern in place to detect this as a mass storage device: udevmonitor reports the device having a module alias of: usb:v0451p6250d0300dcFFdsc00dp00icFFisc00ip00 And modinfo usb-storage shows: # modinfo usb-storage | grep v045 alias: usb:v045Ap5210d0101dc*dsc*dp*ic*isc*ip* alias: usb:v0457p0151d0100dc*dsc*dp*ic*isc*ip* alias: usb:v0457p0150d0100dc*dsc*dp*ic*isc*ip* alias: usb:v0451p5416d0100dc*dsc*dp*ic*isc*ip* Which obviously won't match. So the question is, how do I add a new alias to the module? And will the module even support my device? Ray
