I have a HP HD 2300 Webcam.
Windows 8.1 (64 bit) fresh installation.
eset antivirus/firewall
In Device manager, I have a yellow triangle on the device name, right click>properties I have the following error
"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"
As mentioned, this is a fresh installation, all that has been installed is the antivirus, skype, motherboard utilities. ms office.
I have installed the windows 7 64bit drivers as there appears to be no win 8.1 drivers available from the hp site.
edit: So I have found that Code 19 errors are something to do with the registy, in particular Upper Filters and Lower Filters, I viewed Device Manager --> Properties > Details > Class Lower Filter and Class Upper Filters and found mention of a other items that effect the USB port.. I searched for these in registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ and deleted upper and lower class filters and removed the offending program (a module from Asus AI Suite 3 - AiChargerPlus (it boosts charger amps in the USB for faster device recharging)).. rebooted...
Now the device is "apparently" installed correctly BUT I am unable to get an image on anything (yawcam, skype, and HP Webcam 2300 HD control centre).
The driver being used is usbvideo.sys.. I have deleted it a few times but windows keeps reusing it and (as mentioned earlier) HP dont seem to have a dedicated driver.
