I recently got a Logitech MX518 USB mouse, and I'm trying to get it
working in OS/2.

Here are the USB statements I have in place:

BASEDEV=USBD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBOHCD.SYS /V
BASEDEV=USBOHCD.SYS /V
BASEDEV=USBHID.SYS
DEVICE=G:\OS2\BOOT\USBMOUSE.SYS

I have left the old PS/2 mouse plugged in, and it's completely functional.

With the above drivers loaded, the Logitech mouse can only move up and
down, not side to side. The buttons and scroll wheel work.

Any ideas?

Try AMouse ( http://www.yqcomputer.com/ ). It usually works
much better. It also provides support for up to 7 mouse
buttons and multiple wheels.

Sir:


Get the latest Amouse and be sure to use its USBmouse.sys driver.
Amouse is not compatible with the latest IBM USBmouse.sys driver (Your
system will not boot.).

Thanks a Million!

Well, I downloaded the latest AMouse and installed it.

This what it did to the config.sys:

DEVICE=G:\OS2\MDOS\VMOUSE.SYS
DEVICE=G:\OS2\BOOT\POINTDD.SYS
DEVICE=G:\AMouse\AMOUSE.SYS

BASEDEV=USBD.SYS
BASEDEV=USBEHCD.SYS /V
BASEDEV=USBOHCD.SYS /V
BASEDEV=USBOHCD.SYS /V
BASEDEV=USBHID.SYS
DEVICE=G:\OS2\BOOT\USBMOUSE.SYS

It didn't touch the USB statements, but replaced USBMOUSE.SYS.

My system has one EHCI controller and two OHCI controllers.

Anyway, with the above, the system trapped at startup, blaming CDFS.

I modified the first USB line to this after reading the docs of AMouse:

BASEDEV=USBD.SYS /V /REQ:USBOHCD$

This produced a bizarre message stating that the system did not have
enough space to activate swapping (there's plenty of space on the
designated swapper drive). But it did get to the desktop. The USB mouse,
however, was completely ignored.

I tried changing it to /REQ:USBEHCD$ as well, just in case I'm mistaken
about it being in a USB 1.1 port instead of 2.0, but there was no change
(same odd message about swapping).

I also tried with and without /DEVICE:1 on the USBMOUSE.SYS statement.

After copying the old USBMOUSE.SYS back to try the IBM drivers again, I
get a trap in OS2KRNL. I've now disabled USB completely, and will just
use the old PS/2 mouse, since it appears to be a lost cause.

Check that the IBM mouse driver is not loaded.
REM DEVICE=C:\OS2\BOOT\MOUSE.SYS

Try changing the CONFIG.SYS entries as follows:

BASEDEV=USBOHCD.SYS /V
BASEDEV=USBOHCD.SYS /V
BASEDEV=USBEHCD.SYS /V
BASEDEV=USBD.SYS
BASEDEV=USBHID.SYS


Any chance you have FAT32.IFS loaded together with JFS.IFS and
a big JFS cache size ?


Don't specify /REQ: as this sometimes causes undetected devices.
The driver will figure out the dependencies by itself.
Just correct the order of loading as shown above.


Did you try with unplugged PS/2 mouse ?

What happens if you boot with USB drivers enabled but no mouse
plugged in ? Do you still get the error message ?

I have running a Logitech USB Wheel Mouse with AMouse 2.7b fine here.

If 64MB is big, then yes. I actually had to reduce it down from 128MB a
while ago to allow UDF to load (it also caused strange problems with
SNAP).

I'll knock it down to 32MB, and see if that helps.

There is a new FAT32.IFS on Netlabs that has an option to resolve
this strange dependency. Have a look at the doc. I currently don't
have access to my OS/2 box, so I can't tell you the parameter.

With this fix I run JFS with 120MB cache, FAT32 with 2MB, NTFS with 2MB cache,
UDF, CDFS, CDWFS (RSJ), Tonigy and RAMFS in parallel without any problem.

Hi Mike




Not sure if it makes great difference elsewhere but my system responds
best to usb devices with this order in the config.sys file:-

BASEDEV=USBOHCD.SYS
BASEDEV=USBOHCD.SYS
BASEDEV=USBOHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBD.SYS
BASEDEV=USBHID.SYS
BASEDEV=USBMSD.ADD /V /FLOPPIES:0 /REMOVABLES:5
REM BASEDEV=USBCDROM.ADD


No problems with usb devices here, using an M$ USB Trackball as a
standard 2 button mouse using the IBM drivers.


Just had a quick look through the \os2\boot\usbbasic.txt file on my
system and it looks like load order is critical:-

"Note: After installation from the modified diskettes remove the
parameter /I13 from
the statement BASEDEV=USBD.SYS and rearrange the USB device
driver statements
in the following order:
1. USB Host Controller Driver statements like
BASEDEV=USBUHCD.SYS,
BASEDEV=USBOHCD.SYS,
BASEDEV=USBEHCD.SYS
2. USB Base Driver statement
BASEDEV=USBD.SYS
3. Any Other USB Driver statements"


While the above is in the section about adding usb support to floppies I
think it is also relevent to hard drives.




Suggest you rearrage your config.sys load order as it may (should,
according to the docs) make a difference. Certainly loading the usb2
driver (USBEHCD.SYS) before the usb1 can cause the usb2 driver to not
work here.

Never tried having a 2nd mouse plugged in - could that be causing problems?
