USB Mass Storage Driver for e.g. USB 1.44M Floppy Drive and Iomega 100/250MB portable USB ZIP drive. It works with USB flash drives and USB HDD. 

BASEDEV=USBMSD.ADD /FLOPPIES:0 /REMOVABLES:n
TIP
By Daniela Engert: with BASEDEV=USBMSD.ADD /FIXED_DISK /FLOPPIES:0 /DEVICES:1 the USB Zip 100 should work.
NOTE
During boot USBMSD.ADD creates an empty list with the selected (default1) numbers of devices. Whenever you attach a device it will be connected to this list. This also means, if you attach more devices than specified in the list, they won't be recognized.

Parameter

/V
Verbose Mode, displays driver information during OS/2 initialization.
/A_USAGE
n
Parameter controls usage of 'A' drive flag for the 1st floppy device. The following values of n can be used:
0 - 'A' drive flag is not used;
1 - 'A' drive flag is used;
2 (default value) - 'A' drive flag is used only if there is no other device driver using this flag.
/MAX_FLOPPY
Parameter forces driver to report floppy device geometry with maximal sector count as floppy device physical geometry. With this parameter driver supports LS-120 media formatting but does not support XDF floppy filter features and vice versa.
/FLOPPIES
n :Number of floppy devices to be served (by default 1). In order to remove service the key value must be set to 0.
/REMOVABLES
n :Number of removable media devices to be served (by default 1). For example, the statement "BASEDEV=USBMSD.ADD /FLOPPIES:2 /REMOVABLES:3" serves 2 floppy devices (including LS-120 Super Disk devices), 3 removable media devices (like IOMEGAZIP drive). In order to remove service the key value must be set to 0.
/REMOVABLE_AS_FLOPPY
System uses removable disks as Large Floppies.
/CHS
Driver calculates and adds Cylinder/Heads/Sectors values to device geometry. This key helps to support USB drives with capacity more than 40GB for systems with os2dasd driver without 512GB support and for non-LVM systems.
/MS10_OFF
Driver avoids of using ModeSense10 command for geometry detection.
