Question about HP Compaq nc6220 Notebook

1 Answer

USB applications unable to access Driver

I have a Compaq nc6220 that is not accessing the Cypress, Microchip, STmicro or any other non-standard USB device driver when I use an application.

Unlike older HP laptop models (with the fingerprint scanner) disabling the embedded security and vendor keys has not solved the problem, nor has *not* installing these drivers in the first place.

The Cypress EZ USB Control Panel is able to see USB devices (Hitronic Trainer, devices that I've built and Cypress' Kit) but is unable to program these chips, retrieve a string and will hang on a vendor request. None of the demonstration applications or the newer Cypress Suite will even find an attached Cypress USB device. This is with all possible sixteen logical combinations of driver set, driver definition, EzMr version and external (retail) device.

The typically worthless STRIFD001V1 and SETIFD001V2 both have the same problem; Device manager can see the device and load its driver, but applications cannot, and hang on vendor requests.

The Microchip PICKIT2 I borrowed from a friend (whose older HP laptop I 'fixed' by disabling these features) was also unable to connect to applications but are plainly visible in the device manager.

There also seems to be a curious behaviour in which some requests are redirected to my Logitech mouse, or my embedded Wi-Fi card.
And the Cypress chips are being enumerated as USB hosts for some unknown reason.

The OS I am using is Windows XP Professional SP3 purchased and downloaded directly from Microsoft's (reccomended) retailer Digital River.
The only two HW differences from my laptop to a stock one is a Hitatchi HD to replace the failed Fuji disc, and many of the rubber feet have broken off.

    Clarification: I have reinstalled windows. It did not help.

  • Darren Jul 05, 2010

    Windows Update is not my friend.

    Discovered that a ten year old generic driver or a completely useless dummy driver was being loaded instead of the drivers I was manually selecting and instructing directing windows to install. The windows should have been telling me 'compatible driver not reconised' instead of lying to me outright and doing this {deleted} instead.

    Hacked the INF files to force windows to install AND actually load the drivers I am manually installing instead of that {deleted}. I am now able to program my Cypress chips and a similar hack should allow me to use the PICKIT too.

    Windows trying to stop me from using the ST is actually a mercy, however an overt 'warning this vendor should not be trusted' would have been better.

    Interesting discovery during this; Apparetly Logitech uses Cypress chips in their HID devices, and the CyConsole can reprogram them...

    The problem was that windows was lying to me and automaticaly loading a dummy driver from its database instead of the real one every time I manually selected the driver location. If I find out what vendor included a blanket dummy driver that affets so many different brands I will personally track down the programmer responsible and smack them across the face with their keyboard.

Nc6220 driver for VGA


Hi, CLICK HERE to go to download page. Select your operating system on the page and you will have access to all the drivers for that model. There are 2 possible graphics adapters listed. ATI, and Intel. Try Intel first as most of the ones I have seen have this VGA. If during installation it stops and tells you " no device found setup will now exit" then try the ATI driver package.

I have a Compaq nc6220 and everytime I try to boot up it says "Non-System disk or disk error, replace and strike any key when ready"


This sometimes comes up if you have a disc in the cd drive or a USB drive attached.
If this is not the case, your OS is damaged and you can try a system restore / recovery, you may have these options if you can get the F8 menu to come up while booting.
If you have a windows disc you could try a repair installation, if not google "fix MBR"

Touch pad driver.


Uninstall the driver from the device manager, then reboot. The machine will find the touch pad and reinstall the drive automatically. If this doesn't work, check the touch pad connection, they will sometimes work loose ar get a little dirt/corrosion build up. The connection is under the keyboard. At this point, if it's still not working, then it has failed and will need replaced.
