I have an external LG GSA-5163D DVD writer IEEE 1394 /USB 2.0 which I use
with my Toshiba Satelite Pro A60 Laptop which is running Windows XP with
service pack 2.

The dvd writer connects to the laptop OK, However, when the laptop comes out
of standby the laptop disconnects/drops the external firewire device without
my interaction and the drive is no longer available in "My Computer" as an
optical drive
In order to use the drive again I must disconnect the firewire cable and
turn the dvd writer off then on and once again plug the firewwire cable back
in

Is there an Hotfix which can solve this problem?
Is it a known bug?

The only way around the problem at present is to disable standby, which is
not really a solution or acceptable,

Usually it's required to have drivers from the manufacturer that support
the "return from standby" to work properly. Try contact Toshiba about
the issue?

Thanks for replying.

I have contacted Toshiba and will post any response. There first advise
just disable standby!! They said they would contact me again.

Can you get generic "return from standby" drivers for windows xp?

IF I use the usb 2.0 port the standby function works OK. It is ONLY with
the Firewire connection that this problem appears that is why I was expecting
there to be a xp hotfix of some kind

I don't know about firewire ports, but USB ports has, in device manager, a
tab for power settings, including item "Allow computer to turn off power to
this device.."., or some such wording.
Is there a similar one in the firewire settings on device manager??

I contacted Microsoft support and the solution to this problem is to use
Windows XP service pack 1 drivers for the IEEE 1394 instead of SP2 ones

Here are the steps from Microsoft themselves

"1. Reboot your PC into "Safe mode" and log in as the Administrator account.
(You can choose "Safe mode" by hitting the "F8" key during your PC's boot
sequence.)

2. Launch Explorer and navigate to Windows\Driver Cache\i386
a.Right-click on the "SP1.CAB" file, and choose "Explore"
b. Find the old "1394BUS.SYS" and "OHCI1394.SYS" files (they should have
file dates proir to 2004).
c. Right-click, and choose copy.
d. Paste the files (1394BUS.SYS and OHCI1394.SYS) into the following
directories:
i) Windows\system32\drivers ii) Windows\system32\dllcache
iii) Windows\LastGood\System32\Drivers (may not be present please check if
not ignore this step)
e. Navigate to Windows\Driver Cache\i386.Find the SP2.CAB and rename it.
f. Reboot your PC normally.

3. Respond to any Windows File Protection warnings that you want to keep the
older driver."
