-- If the CX7800 is on, Windows will not boot up during start or
restart. The CX7800 must be off, then Windows boots up perfectly.

When Epson was contacted, this was their reply.

"This issue has been reported on the Dell Dimension 4500c and the Sony Vaio
RX series of computers, though it may also occur on some other computers.
When the BIOS of these computers sends the query during bootup to the Epson
multi-function device, the query is ignored by the Epson product which
causes the computer to hang during its boot. This problem has been reported
on some Dell 4500 computer systems using the Phoenix BIOS PLUS v.1.10 A06
ROM chip and on some Sony Vaio RX systems using the Award Medallion BIOS
v.6.0 ROM chip. The best thing we can suggest to do would be to contact
your computer vendor for a possible update\resolution for this issue.

As a workaround, disconnect the multi-function device from the computer and
turn it off. Reboot the computer, then reconnect the multi-function device
to the computer’s USB port and power it back on. This will allow for normal
operation of both your computer and your all-in-one."

Any comments or solutions?

It sounds like Epson and it's printer drivers along with windows have mutual
problems.
This problem has occurred in the past with different printers and windows
versions.
A device such as a printer should not be capable of hanging windows. About
all you can do is see if updated drivers are available for the printer and
the USB controller. Another item to try is to look at the printer driver and
ports for various settings. Try turning bi-directional off in the driver. It
may be in the ports section of the driver.

If I got this kind of a reply from an OEM, and there was any way I could
return the device, it would be history.

I went thru a similar go around with a Sony 820A DVD/CD burner. When all was
said and done, the device would work in PIO mode if forced. (Windows only)
On the same PC, it would work properly in Linux (UDMA 2 & 4). It would work
in a USB external enclosure. It would not work in windows in UDMA 2 or 4.
Back it went.
 
And do you have one of these PCs that Epson say the problem is limited to?
I don't see that this is a Microsoft issue, Epson seem to have diagnosed it
as a Dell and Sony issue.
 
It's also a MS problem. Has to do with documentation and SDKs, as well as
interaction between software and hardware. In addition, failure of a non
core driver (Core being a driver needed for basic operation) is not supposed
to be able to hang windows. However MS does not control how an OEM writes
drivers, other than furnishing system level documentation and such things as
development kits. If a core driver, such as a USB driver furnished by MS
fails, and hangs the system, that's one thing. If the OEM driver fails, and
it was properly written in compliance with information furnished by MS,
that's another. If the OEM did something off the wall, that's another.

You cannot say that the OEM or MS is at fault. It may very well be that a
specific chip or chipset does not behave as it should, and the MS "standard"
driver does not take this into account. IF so, who or what is responsible
to correct the problem-- The chip(set) mfr, the motherboard mfr, or the
driver (device or system) that is behaving in an unusual manner.

What I'm saying in short is that a printer driver should not be able to
"hang" a system such as windows. Corrective action needs to be taken to
prevent the hang..
 
Since the article references Award and Phoenix who are both the same
company, I would say it was a BIOS issue. As you are probably aware, IHVs
order their BIOSes specifically for their own custom built motherboards....
(HP's in general use mutilated Asus boards, never having owned a Dell or a
Sony, I have no idea who builds their boards)....

So one of these companies needs to go back along the 'chain', contacting the
motherboard manufacturers and the motherboard manufacturers need to then
contact the BIOS writers.
