Yes, It does.
Open Host and Universal Host are different versions of the USB chipset
standards.(Basicly)

Have you updated your eCS 1.1 install with the eCS maintainence tool?
It will make a big difference.

I'm sure it didn't.
Once your USB drivers, kernel and OS2ldr are updated, From a commandline
run hcimonit.exe to see which chipset and how many eCS detected. It
sould like similar to this:

You have 3 PCI USB UHCI host controller(s)
You have 1 PCI USB EHCI host controller(s) < In my case I have usb 2.0
in addition to 3 UHCI USB 1.1 controllers.
For each controller, You must have a BASEDEV statement as shown below:

BASEDEV=USBEHCD.SYS <- 1 USB 2.0
BASEDEV=USBUHCD.SYS < -3 lines of UHCI support.
BASEDEV=USBUHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBD.SYS
BASEDEV=USBHID.SYS
BASEDEV=USBMSD.ADD /REMOVABLES:7 having. See next section...
BASEDEV=USBCDROM.ADD

BASEDEV=USBMSD.ADD /REMOVABLES: By default, Only 1 removable device is
reserved in eCS, The 12 in 1 reader you are working with is really 12
USB card readers and a hub in the little package.
Why? Because these devices support moving data from one memory card to
another in the same reader. Example: I can plug a CF card and a Secure
data card into my 7 in 1 reader and copy files from one memory card to
other without needing 2 cardreaders to do it.
In my case, I had to set my USBMSD.ADD to 7 removables . 1 USB Harddisc,
and the rest for the 7 in 1 reader. Why not 8 you say?
If you look closely at your reader , You will probably find some of the
slots you put the memory in are shared. ( You couldn't put those 2
types of media in the reader at the same time even if you wanted to.)
for each case that exists, You can reduce the removable count by one.
My 7 in 1 reader has a shared slot for SONY memory sticks and SSD cards.
Thereby I needed 6 reservations for that device to work properly.
Why did it work on your P3? Because what ever memory card type you were
using with the 12 in 1 reader happened to be the first detected of the
12 readers detected or the age of the USBMSD driver on that machine is
old and treats all of the reader slots as one.

Try BASEDEV=USBMSD.ADD /REMOVABLES:12 and see what happens..

Hope that does it...
