A7N8X-Deluxe - problems with USB card reader
My USB card reader used for photos has suddenly, for no reason I can fathom,
started not to be recognised. It prevents the system booting up when a card is in place. When I remove the card, the bootup resumes. Also, when XP has booted up, if I open Windows Explorer and try to insert the card, Explorer freezes and only a CTRL-ALT-DEL will get rid of it. I've tried a different card, and a different card reader, with the same result. The card and card reader function perfectly on a different PC. My printer uses USB and that still functions OK. I'm running this system: OS Name Microsoft Windows XP Home Edition Version 5.1.2600 Service Pack 2 Build 2600 OS Manufacturer Microsoft Corporation System Manufacturer ASUSTeK Computer INC. System Model A7N8X2.0 System Type X86-based PC Processor x86 Family 6 Model 10 Stepping 0 AuthenticAMD ~1830 Mhz BIOS Version/Date Phoenix Technologies, LTD ASUS A7N8X2.0 Deluxe ACPI BIOS Rev 1002 Beta 012, 14/03/2003 My IRQ allocation is: IRQ 0 System timer OK IRQ 1 Standard 101/102-Key or Microsoft Natural PS/2 Keyboard OK IRQ 3 NVIDIA nForce PCI System Management OK IRQ 6 Standard floppy disk controller OK IRQ 8 System CMOS/real time clock OK IRQ 9 Microsoft ACPI-Compliant System OK IRQ 10 MPU-401 Compatible MIDI Device OK IRQ 12 PS/2 Compatible Mouse OK IRQ 13 Numeric data processor OK IRQ 14 Primary IDE Channel OK IRQ 15 Secondary IDE Channel OK IRQ 19 RADEON 9500 PRO / 9700 OK IRQ 20 Standard OpenHCD USB Host Controller OK IRQ 20 NVIDIA(R) nForce(TM) MCP Audio Processing Unit (Dolby(R) Digital) OK IRQ 21 Standard Enhanced PCI to USB Host Controller OK IRQ 21 NVIDIA(R) nForce(TM) Audio Codec Interface OK IRQ 21 OHCI Compliant IEEE 1394 Host Controller OK IRQ 22 Standard OpenHCD USB Host Controller OK IRQ 22 NVIDIA nForce MCP Networking Adapter OK IRQ 22 3Com 3C920B-EMB Integrated Fast Ethernet Controller OK I've tried following instructions to re-allocate IRQs but I just can't get those other devices off IRQ20, 21 and 22. I've disabled the printer ports and COM ports in the BIOS but it still insists on sharing the USB IRQs with other devices. Although for all I know that might not even be the problem. Any suggestions would be appreciated. Thanks. Regards, Stuart. |

USB2.0 from the Unified drivers..I had that issue happen awhile back and I needed to disable some options in the BIOS and reinstall USB2.0 |

Replying to my own posts (and top-posting as well!) might be a bit off-form,
but I've found the problem (to save anyone wasting time thinking about it). I read on Google that some CD writing software was causing some people USB problems, as it had a tendency to alter things, so I uninstalled mine, which came free with my DVD-R drive, deleted shared .dll files when the uninstaller offered to, and whaddya know, I got the card reader back!

"dino" wrote in message ... sounds like the system is trying to boot to USB...also try re-installing the USB2.0 from the Unified drivers..I had that issue happen awhile back and I needed to disable some options in the BIOS and reinstall USB2.0 Thankyou for the reply, dino - I've found the solution now. I'm not sure what the Unified drivers are - could you explain? Incidentally, I did try to install the USB 2.0 drivers from the CD that accompanied the motherboard, and all that happened what it opened the readme file for them - it wouldn't install them. In my desperation, I also tried flashing the bios, which I probably should have done anyway since I'm miles behind with it. This worked, amazingly, and I'm now at 1008. Does this do anything exciting? Can I put faster processors in? Regards, Stuart. |

good for you...the Unified Drivers are the Nvidia updated drivers for the
M/B... |
