I too would like to say thank you for the excellent driver! I found it via the ABi forums whilst trying to make a birthday gift work (my aunt did not realize the mp3 player she kindly got for me needed XP and I only have 98se computer

) It has been working since the moment I found one of your drivers and has made us both very happy! I'm having issues with it's conversion software and was trying to find a solution via Google when I landed on MDGX website (which I found last year and have used to
greatly improve my old win98se pc) and while reading realized at the first appearance of this link
http://www.technical-assistance.co.uk/kb/usbmsd98.php that Maximus was in fact the creator of the driver that let my pc see my mp3player!
Since I have read this entire post I thought I would add in my own info and experience with the driver in the event it could be useful to others:
I have win98se, done up with autopatcher from MDGX site and many other hacks and tweaks from there (too many to remember them all!) I recieved Sansa e280 for my birthday, and already had Nikon Coolpix L4 camera spotted by computer before new Maximus driver.
I admit to foolishness because honesty can help fix errors! I knew nothing about "mass storage driver, flash driver, ums,msc,mtp etc." I had never owned one such so I did not know our camera was one! I just installed software from disc so my mom could use her new camera and it worked no problem... that was a long time ago.
1 month ago I receive Sansa e280, I find Maximus' driver
nusb31e and I installed it, but without removing other drivers because I didn't understand cameras were mass storage and I was afraid to remove our HP usb printer driver because it was
very hard to get working on usb. That driver would not install and I tried many times, the error said it was unreadable or something - since I had saved it to a floppy on my aunts XP machine and brought it home to mine I thought XP had saved it funny

So instead I downloaded
nusb30e and it installed fine even with other usb drivers still on machine! Now I could see my player as drive f: and its microSD slot as drive g: and I drag music over like crazy-happy-fool!
And fools are foolish so... I did not see "unplug usb device icon" down in system tray for first few days so I was just unplugging it like we do to the camera. I must report that I had no problems with the device and not one BSOD either, nor any hanging of PC. Of course since I have found it I use it because it seems it must be there for good reason!
I am wondering if because I have USBSTOR.SYS 5.00.2195.6655 understanding from earlier in the thread that it was downgraded in ver3.1 (Maximus Decim Native USB ver.3.1 What's new? *Downgrade USBSTOR.SYS (4.90.3000.1), removed wdmstub.sys) if that could be why I could not install the latest version? I think that file confirms the device is there sort of? I ask because although windows explorer sees my sansa and I can paste music in msc mode I think it does not actually register anywhere because USBView (found here) does not see it when it is connected nor does my photo conversion software

which is what got me searching the internet and landing here to begin with! Only explorer sees it, so I can have music but no movies and no photos because you have to use that *%#@!! software to put on picture/video. Possibly there is someway to make the player no longer invisible by filling in some spot in the registry?
I'm sorry for talking so much

but I'm hopeful now because I know there are smart people here and this is where the first thing that made my player work came from so maybe someone knows how I can access all it's features?
Thank you so much Maximus and everyone here!
