dmesg not reporting the mount point on USB insert
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? Thanks. William

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. https://wiki.debian.org/udev If you start #udevadm monitor before inserting the stick you can monitor the system events on the fly.

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

Thanks to all for your help! I dug into it, and somehow usb-storage wasn't running. I probably could have manually started it, but I tried a reboot first. That works! Always a bit embarrassing to use the Windows solution, but when it works, it works. Thanks again. On Fri, Mar 16, 2018, 13:50 Bob Jonkman via talk <talk@gtalug.org> wrote:
