Excited by madmaxUSB's info (June 28, 2003), I went a bought a USB flashcard reader. Package claimed it was Plug 'n Play, no driver needed. Hooked it up, booted from A: with CONFIG.SYS : DEVICE=A:\HIMEM.SYS /N=48 /V DOS=HIGH,UMB SWITCHES=/F BREAK=ON FILES=60 BUFFERS=30 STACKS=9,256 LASTDRIVE=Z DEVICE=A:\aspi.sys DEVICE=A:\USBASPI.sys /V /U /R /noprt DEVICE=DI1000DD.sys Got the following output from ASPI.sys : OAK ASPI for ATAPI version 1.10 Transfer Mode : Programmed I/O Number of Drives : 2 and from USBASPI.sys : Controller : 00-07-2 VID=8086h PID=7112h (0000h-0000h) UHCI : I/O=EF80h-EF9Fh USB Device : HOST[00-07-2 VID=8086h PID=7112h 90000h-0000h) UHCI] : |--VID=0C45h PID=1050h FS : ^-- 1 device(s) ASPI Device : ID:0 LUN:0 = USB MASS STORAGE DEVICE 0.10 and from Di1000dd.sys : DI1000 ASPI DISK Driver Ver 2.00 WORNING : Found many ASPI host adapters Please put on adapter number by option switch (/H) HA #0 : IDE Controller HA #1 : USB Mass Storage Driver install abort Tried everything I could think of for switch /H, always "Illegal switch". So, can anyone tell me what I'm doing wrong? Why do I need ASPI.sys (Di1000dd.sys says "no device found" if I don't include it)? Does anyone know What are Di1000dd.sys's switches? ASPI.sys's switches? I feel I'm groping in the dark here. Does anyone knows where to look to find out? Incidentally, USBASPI.sys reported "No devices found" unless I included the /noprt switch. Looks like it's connected with I/O port address. RodUSB

Plug 'n Play, no driver needed Is true for Windows 98 onwards only! Article here: http://theinquirer.net/?article=10215 Plus try. USBASPI in DOS Search at top of this page for other posts on the subject. madmaxUSB has posted more than once on the subject!

Personally use an extremely minimal MSDOS boot disk, like the one you can create within XP which is the equivelent of version 8 DOS (ME). I ensure the USB devices are functioning prior to intergrating into a DOS system. Please be aware that USB in DOS is not supported by manufacturers. If you are going to use the USB drive for drive imaging/cloning then look at following as unlike Symantec products does not use PCDOS: http://www.acronis.com/products/trueimage There are several USBASPI drivers avaulable and the most reliable seem to be the version 2.x Panasonic, though look at following for other manufacturers offerings: http://www.mwpms.uklinux.net/usbfire.txt

The article from theinquirer.net isn't that useful. RodUSB, When ASPI.SYS and USBASPI.SYS are both loaded, you need to specify the switch /Hn for DI1000DD.SYS, where n is a number, instead of just /H. For example: DEVICEHIGH=DI1000DD.SYS /H1 --------------- Long Live DOS!

DI1000DD.SYS ASPI Disk Driver v2.00 from Novac Co., Ltd device=[{path}]DI1000DD.SYS [/hN] [/dL] If USBASPI.SYS detects multiple mass storage devices on multiple host adapters, use /hN Host, to specify which host adapter to map drive letter(s), where N would be the 3rd number set reported for the USB controller in USBASPI.SYS with the /v switch. To specify the starting drive letter for detected mass storage devices, use /dL Drive_letter, where L is the first assigned letter for this host adapter Am not sure if it would be DEVICE=DI1000DD.sys /H1 or DEVICE=DI1000DD.sys /H2 though... Please feedback what works.

I connected 3 USB 2.0 drives to my Dell CPxH 500 MHz PIII notebook. 2 were connected via a 2 port 2.0 PCMCIA (Belkin) and one via the internal 1.1 port on the back. As it booted I saw two HS drives and 1 FS drive, and all the equipped USB controllers and addresses. I found the files out on the net. ASPIDISK.SYS is from Adaptec's site and the USBASPI4.SYS is the latest Panasonic driver, also found thru google. Here's my config.sys: device=himem.sys /testmem:off device=usbaspi4.sys /v device=aspidisk.sys It also picked up the PCI 3 port 2.0 card in another PC, that I had the same 3 drives connected and they all showed up as HS drives. I did a test ghost from this machine. The partition was 1.9 GB and took 17 minutes to ghost on the Fastest setting, to the USB PCMCIA 2.0 connected drive. The image was just over a gig. It took several hours to find these but there there. KR
