++usb-test-modes 
++
++This is best built as a module which may be inserted into a running
++Linux system only when needed.
++The module can be built as part of the standard kernel module build
++if the correct options are chosen in the config. 
++
++
++How to use:
++
++copy the usb-test-mode.ko file somewhere convenient on the NAS and
++insert the module into the system using
++'modprobe usb-test-mode.ko'
++
++It should report successfull loading or an error message. Assuming it is
++successful /proc will have an 'usb_test_mode' entry (verify with ls).
++
++Actions:
++read the current port status:
++cat /proc/usb_test_mode/read
++
++set port 1 into test mode 4:
++echo 4 > /proc/usb_test_mode/write1
++
++
++When testing is completed the module can be removed from the linux
++system using:
++rmmod usb_test_mode
++
++ahb_mon 
++
++This should be built as a module. 
++
++How to use:
++
++insert the module into a working system by typing 
++'modprobe oxnas-ahb-monitor'
++
++When successfully installed a directory  entry will appear in /proc for
++oxnas-ahb-monitor. In the directory will be a writeable file for each
++AHB monitor and a control file. There will also be a readable file for
++obtaining the counts stored in all the ahb monitors.
++
++
++Actions:
++set a monitor to a limited range, burst mode etc using
++low addres, high address, mode, burst mode, burst mask, hprot, hprot mask
++
++Use the echo command to set data into the /proc/oxnas-ahb-monitor an example is

++ * This is the only non-restricting portion of this module, since it -does-
++ * in fact give additional permissions.  However, in the inode_permission hook,
++ * any rights the user should not have are taken away.
++ *
++ * Side effects: Posix ACLs or other filesystem-specific permissions are not

++ * permissions, but any permissions further than that are difficult, to say
++ * the least, to take into account.  I, personally, do not find this to
