Trying to identify this Serial > USB adapter

Thanks DL, I guess my issue is my new system then. When trying to
install the device(Art Tablet) using the adpater, I get an error that
"All serial ports are in use", but I am assuming that it can't find
any serial ports? I was thinking the device drivers for the adpater
would add a serial port?

I opened the adapter and found some info on the circuit board, but no
luck searching the net for info.

Thanks again for any help.

From what I was able to find, this thing is a USB/Serial
converter designed specifically for the CyberPower UPS
units. Found this in their Support section:

------------------------------
8 . How can I connect the UPS with a USB cable?
Contact tech support and request a USB converter order form.
------------------------------------

The driver for it is likely embedded in the PowerPanel applet
they supply to monitor the UPS.

If you really need a USB/Serial converter, I would quit
messing about with this one and go buy another standalone
USB-Ser. cable.

Bullsh*t.

These things ALWAYS require drivers.

But I've never seen one like this before...

Maybe if the little adapter circuit board was turned over,
there would be an IC soldered on there ? Something has to
convert from one protocol to the other, like an FTDI
chip or something similar.

The reason I suggest turning the adapter board over, is
the usb-serial2.jpg picture, shows a quartz crystal in the
tin can, and that only makes sense in a circuit, if there
is an IC using the crystal as part of an oscillator.

If there is an IC, then the part number on the IC, might
give a hint as to where to look for a driver.

While it is remotely possible to dual define the USB pinout
to either be +5V, D+, D-, GND when USB and TXD, RXD, GND
when used in a serial application, the presence of the
crystal tin can cannot be explained, if the adapter is just
some kind of level shifter.
