It might work, since the driver model of OS/2 hasn't been changed since Warp 2.0.
TRy it out.

I have tried it; BIOS will recognize a travel drive, but I cannot access the drive using OS2. I assume I need a driver to do so?

Working with Warp 3, I've found that some of the newer USB drivers from IBM won't work with the Warp 3 kernel, but the older drivers, and the CW-USB drivers work. I'd suggest these would be the best bet.

Thanks for your reply!! I will try WARP and see if I can get it to work, but I have to stay with OS2 2.11 for now for the sake of continuity of the project. This is a Combustion Turbine control application, so I cannot switch operating systems until I thoroughly test; my gut is Warp will work and as soon as I have replaced all the Multi-bus 386 processors with Pentiums I will try it.

Well, I'd try it with OS/2 2.11 then, there is a chance things may work.

Given the need to stick with 2.11, my best suggestion is to try the CW-USB drivers at:

http://hobbes.nmsu.edu/cgi-bin/h-search?key=cw-usb&pushbutton=Search

Also, for myself I've had very limited success getting the "USBD.SYS" or "CWUSBD.SYS" driver to properly recognize mass storage devices. There is a modified version of USBD in the MMPORTV1.ZIP file, available at:

http://hobbes.nmsu.edu/cgi-bin/h-search?sh=1&button=Search&key=mmportv1&stype=all&sort=type&dir=%2F

While things may be different, here's what makes it all work in my config.sys:

rem working USB stuff
BASEDEV=CWUSBOHC.SYS /V
BASEDEV=USBD.SYS /REQ:USBUHCD$,USBOHCD$,USBEHCD$,CWUSBUHC$ /V
BASEDEV=CWUSBMSD.ADD /V /FLOPPIES:0 /REMOVABLES:2 /REMOVABLE_AS_FLOPPY /FORCE_TO_REMOVABLE
rem end of working usb stuff

Of course, depending on your chipset, the first line could call the CWUSBUHC.SYS driver.

And the USBD.SYS came from the MMPORTV1.ZIP file.

I think it also needs to have the lastest OS2DASD.DMD driver to work, but I'm not sure on this.

Hope this helps.
