Question about HP Compaq nc6220 Notebook
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.

STmicro doesn't deserve a link.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
