Hello,

I have a DatOptic Speedzter 2.5 that I'm trying to get to work with USB in DOS. Naturally, I'm trying to use the DatOptic drives (by MediaLogic), but it's not working. (I've tried the Panasonic usbaspi.sys & some others w/ no success.) It generates the following errors:

ERROR : EHCI memory mapped I/O can not assigned.
ERROR : Target USB device not found.

Does anyone know how to get this working?

I'll post the entire verbose mode printout & some more details at my website.

I'd appreciate some help.

Thanks,
PPain

USB 2.x EHCI (Enhanced Host Controller Interface, your device is USB1.x.

Do you know what USB ChipSet you have?, and wether on board or PCI Card?, have you tried the NOVAC USB ASPI driver?

Have you tried other switches? see:

www.mwpms.uklinux.net/usbfire.txt

x86

I'm pretty sure the USB ChipSet is made by Intel. It's onboard. I don't know how to get a version #. The Dell GX260 is a fairly new machine.

I've spent a lot of time looking at www.mwpms.uklinux.net/usbfire.txt

I've tried:
Panasonic
DUSE
Novac (Mhairu)
Medialogic

DUSE seemed to get closest to working. Its error was something like "C Drive not installed", which didn't make any sense to me, but it seemed to properly initialize the USB. I tried "/late" followed up with "init" from autoexec.bat. That didn't help.

Since the Medialogic driver is distributed by DatOptic, the manufacturer of the Speedzter, one would think it would work. It's probably a matter of using the right switches. I've taken a stab at a few, but with no success. I can't find any documentation. Do you know what switches are available for the Medialogic driver? The only guess that has shown a different result is "/v".

PPain

The "/u" switch fixed the EHCI error. However, the "Device not found" error remains. Still a show stopper.

PPain

Have you tried either the Panasonic or Novac in conjunction with the DI1000DD.SYS driver??

Also try the making a minimal boot disk, in the command promt window of windows SYS A:
then adding the following lines at the begining of config.sys;

device=usbaspi.sys /v/w/u
device=di1000dd.sys

I have found in one case that DOS was allocating a memory area used by these drivers, therefore against common practice load them before HIMEM.SYS & EMM386.EXE etc

btw were you using the Medialogic driver as the complete downloaded boot floppy?? or just extracting files required??

Lastly are you using an external power supply??

Good Luck

Hi Nathan

Definitely, GX260 is using USB2.0 from Intel's 845 chipset so obviously you want the DATOptic Speedxter to run at USB2.0 speed.

Some of the options in Panasonic's v2.06 driver do work in the Medialogic's v2.01 USBASPI.SYS driver.

From your website:

---------------------

From your error message:
1. USBASPI.SYS cannot map your EHCI controller. What happens if you use /E option instead of /U ?
2. Do you have any add-on card (PCI) installed? Can you try removing it first?

I will try the drivers on a Dell and get back to you...

Visit this link for deeper insight on USBASPI.SYS options and use:

http://www.computing.net/dos/wwwboard/forum/13447.html

To answer all questions from above:
- I'm using an external power supply for the Speedzter.
- I turn the Speedzter on before booting the computer.
- I'm booting from a floppy made by the DAT.exe on the DatOptic website. I've copied various other drivers to this disk so I can easily switch from one driver to another by editing config.sys.

I tried a few different switches.

/e
- with Medialogic - generates another error "PCI UHCI/OHCI/EHCI USB controller not found". Despite "/v" text is severely chopped off.
- with Panasonic - doesn't generate the above error, but the /v text becomes much shorter and it still can't find the target device
/u - seems to be most promising. I'm pretty sure the Speedzter isn't capable of USB2 anyway.
/slow
- with Medialogic - illegal option
- with Panasonic - tells me it's entering slow mode, but doesn't fix any problems

I tried using di1000dd.sys, but since the ASPI Manager is the problem, di1000dd.sys simply errors out "ASPI Manager not loaded". This is the same as what happens with nj32disk.sys (Medialogic).

PPain

Just to clarify:

When using the /u switch (either Medialogic or Panasonic), the only error which seems to be stopping the chain is "Target USB device not found". This is the first error to appear. The other error (which comes after this) is associated with the disk driver, not the USB controller driver.

PPain

Have you tried the Novac driver??

Also have you tried not plugging in the device by using the /W/V switches which pauses install until device plugged in??

Just a thought have you tried another USB cable?? and does this disk actually work under windows??

I have tried the Novac driver. Didn't work.

The Speedzter does work under windows with the same USB cable.

I'll try turning on the Speedzter during the pause of the /w.

PPain

Since it works on Windows, could you go to ControlPanel - System, enter Device Manager and check out what resources are used by each USB Host Controller (you should have UHCIs and an EHCI)?

Compare with what is reported by USBASPI.SYS

Finally, please look for any conflicts - click on resources by connection or type and see who are sharing I/O, memory or IRQ with the Enhanced Host Controller reported.

madmaxUSB,

I took some screenshots of various device manager pages under Win2k with the Speedzter running. They're on my website.

The I/Os seem to match their DOS counterparts. Beyond that, I don't know what I'm looking for.

PPain

You previously said:

/u - seems to be most promising. I'm pretty sure the Speedzter isn't capable of USB2 anyway.

I think if you are really happy to operate in USB 1.x mode (max 12Mbps) then this is your best option. What it does essentially is allow operation of UHCI host controllers and disabling the other host drivers (EHCI and OHCI).

However, looking at the DAToptic website, all I see are USB 2.0 enclosures so you might be missing out on something.

I do point out thought that

Here is the result of my tests on TWO DELL OPTIPLEX PC's - one is GX260 (BIOS Rev A05) and the other is an L60 (BIOS Rev A00). Both use the 82801DB/DBM to provide USB 2.0 ports onboard.

In BIOS setup, both have under Interface Devices:
USB Emulation = OFF
USB Controller = ON
While under PCI IRQ, both have 4 Intel USB Controllers each using interrupt 9, 11, 10 and 3 respectively.

With the DAToptic Speedzter disk, I got exactly what you reported with the Medialogic 2.01 USBASPI.SYS /V /W which is this:
ERROR : EHCI memory mapped I/O can not assigned.
ERROR : Target USB device not found.

However, when I replaced the driver with the Panasonic 2.06 USBASPI.SYS /V /W it WORKED and the UHCI controllers are I/O mapped while the EHCI controller was MEMORY MAPPED - for the USB2.0 host controller, you get a line going like this:
Controller : 00-0n-n VID=8086h PID=nnnnh (nnnnh-nnnnh) EHCI
: MEM=FFA00800h-FFA00BFFh(1024Bytes)

Your Resources by connection screen capture is actually displaying the USB 1.x UHCI host controllers (24C7, 24C4 and 24C2) but what we are looking for is under Memory - we need to see what address range the Intel PCI to USB Enhanced Host Controller (USB 2.0) is using.

I suspect 3 possibilities:
1. Because you are using a USB mouse, is your BIOS setting for USB Emulation ON? Would setting it OFF cause different operation?
2. You have a number of SCSI hosts - 5 different ADAPTEC controller entries, a Dell PERC, a Future Domain HA, HP NetRAID 1Si and a PCMCIA SCSI controller installed and one of them probably conflicts with the Intel EHCI standard memory map address FFA00800-FFA00BFFh. Can you remove all of them for a moment and check for conflicts by returning one at a time?
3. The PCI BIOS has already mapped EHCI to a non-standard address space and the only way to put it back to default is clear the BIOS config (and remove all add-on cards) - but this may cause Windows configuration settings to change drastically so this is NOT recommended.

madmaxUSB,

Thank you very much for the help you're giving.

I added a screenshot to my webpage for the memory section of Resources by Type.

I switched USB Emulation to OFF in the BIOS and used Panasonic /v /w. The USB mouse still works fine in Windows, and the EHCI error did not show itself when booting from the floppy.

The only error remaining is "Target USB device not found." This prevents the ASPI Manger from loading, which prevents the HD driver from loading as well.

PPain

I presume you have removed Mouse and tried in other USB ports??

Can you update your web page to show what USBASPI.SYS (v2.06) displays with the /V /W options ?

I have gotten my 2.5" USB-IDE box using Genesys chip to work with no problem.

Could it be that the partition isn't FAT16/32 and thus cannot be mapped to DOS?

madmaxUSB yes you are correct about FAT, with my external compact flash / smart media if I format them under XP, and I would presume W2K, they are not readable under real DOS, though they are recognised as drives and assigned drive letter. Great you achieved another device working!

Was the first comment directed at my web page??

PPain, would personally remove all PCI cards etc and unplug IDE's and USB mouse, just run from a boot floppy and try to see if recognise drive, to see if there is memory area conflict!

Hello,

I updated my webpage.

This computer doesn't have any PCI expansion cards. Everything is onboard.

The HD in the Speedzter was formatted Fat32 under Win2k. Unlike your experience, x86, the Speedzter isn't recognized as a drive or assigned a drive letter.

I've tried disconnecting the mouse.

I've tried moving around to different USB ports. I can get the Speedzter to move to different USB controllers, but not to the EHCI controller.

Details of all this are on my webpage.

PPain

Oops - sorry for the misdirection - your Resources by Type shows the Speedzter with a Toshiba HD is actually just a USB 1.x device - at least the USB 2.0 functionality is now available in DOS ;-)

So the root problem was even with UHCI, we get "Target USB device not found."

Question - are you using the correct version of USBASPI.SYS from Panasonic - your webpage indicates ASPI Manager for USB mass-storage Version 2.01 when the latest is actually v2.06 ...

Note that USBASPI.SYS actually does see your Speedzter because scenario 3 has
: |-- VID=07F7h PID=000Bh FS
but scenario 4 doesn't.

So the problem is USBASPI somehow doesn't think of the device as a compatible mass storage device - which is in itself strange as the experience of others is it is usually recognized and mapped as an ASPI device but the next driver cannot map it to a disk.

There are a coule of reasons I can think of on why this is happening:
1. Something is non-standard about the partition created. Maybe if we open the case, connect directly to a PC IDE port, backup, repartition under just DOS, and restore, the problem would disappear...?

2. Or alternatively, if we open the case, connect directly to a PC IDE port, backup, remove all partitions on that disk and put it back in the Speedzter case. Then boot from DOS and load the USB drivers to see if we can get it to recognize the disk, and then create the partition. After a reboot, format the partition. If it all works, boot in Windows, connect the USB drive, map the external drive and restore all data.

3. Something is non-standard about the USB-IDE bridge (maybe early generation) making it incompatible with these drivers. Have you tried the other drivers like IOMEGA ASPIUHCI.SYS driver?

Admittedly, this is a lot of work.

HTH

madmaxUSB,

The v2.01 was a typo. Now corrected. I actually took digital photos of the screen as it scrolled by, so I've verified it's actually 2.06.

I think I'll reFDISK & reformat the HD under DOS on a different computer via firewire. Maybe that'll accomplish the same thing as your two HD removal options above.

If that doesn't work, I'll be asking where to find that IOMEGA ASPI driver. I hadn't heard about that one.

Thanks for all your help.

PPain

I realized I can't fdisk Speedzter from dos. The installation manual says you have to do it from windows.

I hooked it up to a Win98 machine (USB) to fdisk (delete & create) and format (fat32).

It didn't fix the problem.

I tried Medialogic again. Problem still there. I took away /u, and the EHCI error came back, despite USB Emulation being off in the BIOS.

Where could I get a copy of the IOMEGA driver?

PPain

Try the "Iomega USB / Firewire Boot Diskette" from:

http://www.stefan2000.com/darkehorse/PC/DOS/Drivers/USB/

There is an updated ASPIEHCI file. You cal also find it if you have a recent version of Norton GHOST

Have extracted Ghost files and sent to you...ASPIxxxx............

I tried the IOMEGA drivers. Same result.

It appears as though I've exhausted all my options.

Supposedly DatOptic is "getting with their engineers". We'll see what comes of that.

Thanks for all your help.
