Is the system, as you called it, on /dev/sdg3? Has the device to be bootable?

As a side node, using a flash-drive partition as swap is generally a bad idea, since they only survive about 10000 write cycles.

Exactly the case I need to have spare flash hdd system stick - scsi device.
How long does it for 100000 write cycles to complete ?

I suppose, the device has to be bootable.
Linux firmware is already installed in router's internal flash memory.
hdd flash usb stick as system with
part1 swap
part2 /opt
part3 /tmp data

I can use router if hdd usb flash stick is in and out.
In case it's out, I get standard router's functionality by Asus.
With usb stick in I get access to ipkg packages, installed applications,
root access and more.

As it took me months to install and configure some applications
and recently I native compiled Unix Linux dialog utility with examples running and being tested, I need to keep my Linux environment as safe as possible, keeping spare system usb flash for use in case it is necessary.

thanks

LEARN ABOUT LINUX

usb-devices

usb-devices(1)							Linux USB Utilities						    usb-devices(1)

NAME

       usb-devices - print USB device details

SYNOPSIS

       usb-devices

DESCRIPTION

       usb-devices is a (bash) shell script that can be used to display details of USB buses in the system and the devices connected to them.

       The  output  of	the  script  is similar to the usb/devices file available either under /proc/bus (if usbfs is mounted), or under /sys/ker-
       nel/debug (if debugfs is mounted there). The script is primairily intended to be used if the file is not available.

       In contrast to the usb/devices file, this script only lists active interfaces (those marked with a "*" in the usb/devices file)	and  their
       endpoints.

       Be advised that there can be differences in the way information is sorted, as well as in the format of the output.

RETURN VALUE

       If sysfs is not mounted, a non-zero exit code is returned.

FILES

       /sys/bus/usb/devices/usb*
	      The part of the sysfs tree the script walks through to assemble the printed information.

       /proc/bus/usb/devices
	      Location where the usb/devices file can normally be found for Linux kernels before 2.6.31, if usbfs is mounted.

       /sys/kernel/debug/usb/devices
	      Location where the usb/devices file can normally be found for Linux kernel 2.6.31 and later, if debugfs is mounted.
