Latest working kernel version: ? Earliest failing kernel version: 2.6.25.2 Distribution: Debian (etchnhalf + stable) Hardware Environment: Dell Latitude XT (a tablet) Software Environment: Debian stable, plus proposed updates, plus 2.5.25.2 kernel Problem Description: Booting with an Edgeport/4 plugged in results in the attached serial ports /dev/ttyUSB2, ttyUSB3, ttyUSB4, and ttyUSB5 instead of /dev/ttyUSB0, ttyUSB1, ttyUSB2, ttyUSB3. Unplugging and re-plugging the USB device results in attached devices /dev/ttyUSB4, 5, 6, and 7. The infamous "io_ti: probe of 1-2.1:1.0 failed with error -5" message of bug# 10426 shows up in the dmesg output both at boot and when re-plugging the USB device. Attached are dmesg output, the .config for the kernel, and /proc/bus/usb/devices. I am sorry but I will have very minimal access to this hardware configuration from this moment forward and it is unlikely I will be able to do further testing.
Created attachment 16071 [details] .config for the 2.6.25.2 kernel
Created attachment 16072 [details] cat /proc/bus/usb/devices After initial boot which occurred with the edgeport/4 plugged in (during boot.)
Created attachment 16073 [details] dmesg output after initial boot dmesg output immediately after boot. Edgeport/4 plugged in during boot.
Created attachment 16074 [details] dmesg output afger unplugging and re-plugging edgeport4

This isn't a bug, the option device is getting assigned those lower tty numbers, as it is plugged in. Closing out.

This is not a bug, you have the option driver loaded which takes up the lower numbers. I have closed this bugzilla entry out. thanks, greg k-h
Thank you for your time.
(And sorry to have troubled you.)
