Hi,

Here we have a Sandisk MP3 player, which under Windoze appears as nothing more than a FAT32-formatted MSD.

Using USBOHCD.SYS and USBD.SYS from DD03, v1.2 of Chris W.'s USBMSD driver, and FAT32.IFS v0.99... 


Maybe the IBM USBMSD.ADD would be better along with the current OS2DASD.DMD.



Since adding the USBMSD driver with the /REMOVABLES:1 switch, a mysterious and inaccessible drive F: has inserted itself between my last hard drive and my two CD drives. Attempts to access F: under a variety of circumstances consistently return a "drive not ready" error. I would have been happier had it appeared in sequence ~after~ the CDROM drives, but that's trivial.


Does the CW driver have a /FLOPPIES:0 option? or maybe it has an option like Removable as large floppy enabled?

Are you loading USBCDROM.ADD - that could also cause a "phantom" drive .



Upon plugging in the MP3 player, no reaction is observed from the system by way of either the expected beep as USBMSD detects the removable device, nor does the USB Resource Manager list it.



Could well be the problem of USB2 device and USB1 controller/driver not "talking" to each other properly - something the above current IBM releases are meant to fix.


Here's the catch: upon unplugging the MP3 player, a system beep is triggered, and the Sandisk device appears in the USB Resource Manager... for all of about 3 seconds. Shortly thereafter a second beep is heard, and the MP3 player is no longer listed in the USB Resource Mgr.

As the song says, Where do we go from here?



I suggest that you give the IBM drivers a try. Also the fat32 package has been updated - may be relevent.
