[Discussion] USB Memory Sticks

[Thomas Clayton]

Dear Brian:

I have a 1GB and I am ACTIVELY attempting to get it to 'be seen' under
Warp3 (yep, I said three 3!). (Just started the attempt this day. Came
here to library to get some reminders about switch settings on device
driver lines.)

Here's a snippet from CW's advice:

    5 USB mass storage class driver

Enhanced USB mass storage driver which supports more (or other) devices
than the IBM version. Support for READ 10 commands and better disk
geometry handling. Can force external hard disks to appear as removable
devices.

The driver supports the following switches:

*/V* 	Verbose, show some information while booting.
*/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.
*/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.
*/REMOVABLES:n* 	Number of removable media devices to be served (by
default 1).
*/FIXED_DISKS:n* 	Number of fixed disks to be served.
*/CDS:n* 	Number of CD-ROM/CD-RW devices to be served (by default 1).
*/REMOVABLE_AS_FLOPPY* 	System uses removable disks as partitioned
volumes:

BASEDEV=USBMSD.ADD /REMOVABLE_AS_FLOPPY

*/FORCE_TO_REMOVABLE* 	Change external hard disks (for example Archos
Jukebox) to removable. This may be necessary if a device anounces
itself
as a fixed disk but you want to use it as a removable device.

Add the following line to CONFIG.SYS to install the driver:

      [...]
      BASEDEV=CWUSBMSD.ADD /V /FLOPPIES:0 /REMOVABLES:1 /FIXED_DISKS:0
/FORCE_TO_REMOVABLE
      [...]
"


I'll let you know (in my next letter?) how IF obtained success!

SINCE you have the more modern IBM MCP / SS-eCS USB 'kit' do NOT use
the CW driver, itself!!!

HTH!
