In the past, when I stuck a USB stick in to my computer, I would look at dmesg and see that the device had been assigned a place in /dev. This week, I can see the device's details (Lexar, Sandisk, whatever), but there is no line for where I can address that device. Graphical file managers are also not showing the inserted media (I have tried several different sticks and card readers).
I imagine that something changed in Debian that has lead to this, but I can't tell what's missing. ehci is picking up the device insertion, but not giving me a place to use in a mount line. Anyone have any thoughts?
Might need a new udev rule for whatever reason.
If #lsusb output shows the device assignment you can use "udevadm info --attribute-walk --path=/dev/bus/usb/xxx/xxx in order to walk the path attributes and get the info needed by udev rules which are held in the rules.d directory.
If you start #udevadm monitor before inserting the stick you can monitor the system events on the fly.
Does 'lsusb -t' show the device. I would think either usb-storage module isn't loaded, or the device is not actually being detected. Since you say ehci detects it, then I wonder if it just isn't being picked up as usb-storage. -- Len Sroensen
