I want to install a system on my notebook computer. I don't have a CD-Rom on my computer. I only have USB port on the notebook computer. This computer can startup with USB floppy disk. I have download a software for USB port CDROM in DOS config.sys DOS=HIGH,UMB lastdrive=Z device=HIMEM.SYS device=emm386.exe devicehigh=USBASPI.SYS /v /w /e devicehigh=DI1000DD.SYS devicehigh=USBCD.SYS /d:USBCD001 autoexec.bat mscdex /d:usbce001 /s /m:15 /v when system boot ,it display error message : ERROR: PCI UHCI/OHCI/EHCI USB host contoller not found

Are you using the Panasonic version 2.06 USBASPI.SYS and USBCD.SYS version 1 ?? Your autoexec.bat is wrong it should read: mscdex /d:USBCD001 Have you enabled USB in BIOS ?? Have you enabled boot from USB Floppy in BIOS ?? Also try the DATOPTIC self extracting boot floppy if the Panasonic driver is not recognising USB controller ! Download links: www.mwpms.uklinux.net/usbfire.txt and look thru http://www.computing.net/dos/wwwboard/forum/13845.html

btw also try after USBASPI just /v /w

I have two usb device ,one is cdrom for usb2.0 ,other one is floppy disk maybe for usb1.1. When I use USBASPI.SYS /v/w it say Controller: 00-07-2 VID=8086h PID=7112h (0000h-0000h) UHCI : I/O=FCE0h-FCFFh USB Device: HOST [00-07- VID=2 VID=8086h PID=7112h (0000h-0000h) UHCI] : |--VID=03f0h PID=0207h FS : ^--nothing ERROR : Target USB device not found When I use USBASPI.SYS /e it say "PCI UHC2/OHCI/EHCI USB host controller not found" And both of it say: ASPI manager not installed. what is the problem?

Did you follow previous advice ?? Try different USB drivers ! Is the CD drive self powered ? btw you only have USB 1.x controller !

> When I use USBASPI.SYS /e it say "PCI UHC2/OHCI/EHCI USB host controller not found" This could mean your portable does NOT have USB 2.0 support - only USB 1.x. Can you confirm the specs? If only USB 1.x, the use: devicehigh=USBASPI.SYS /v /w >: |--VID=03f0h PID=0207h FS But here is the device: 03f0 Hewlett-Packard 0207 CD-Writer Plus 8200e So the question is why is it saying > ERROR : Target USB device not found ? Can you check the HP web site for firmware updates for this product? Try searching this forum for similiar complaints on an HP USB CD rewriter
