Jul 19, 2013 Windows isn't detecting my USB MIDI Keyboard. Identifying 'casio usb-midi'. Look at the list for the Casio MIDI diver. Delete the driver. Hey, guys, if you are one of those people who just themselves Casio USB Midi for their laptops or other desktop computers then it is sure that you are also going. Gator boat trailer serial number.
Jirka For what it is worth: Several years ago, when I replaced my failed Vista-32 system with a Vista-64 unit, I lost communications with my WK-3800, because Casio never wrote a Vista-64 driver for the WK-3XXX units. Several years later, when they did release the current Win-7/8 64 bit driver for the WK-3XXX models, I tried it on my Vista-64 system. It installed and ran just fine, and is still running just fine today - even though Casio still insists that it is not compatible with Vista-64.
When I say 'runs fine', that includes basic communications between the WK-3800 and the PC and the IDES Data Management software. Typically, Windows checks drivers for compatibility prior to installation, and if there is an issue, it will refuse to install them.
Anvil Studio-among many other features-also has a live notation function which works pretty well. This has a freeware edition or a paid version if you need the extra functions, although it is a completely functioning program without the paid version. Once installed, click on the 'view' menu on top of the screen, then select 'compose'-select open for a list of sample.mid files in the program, or 'new' to start your own. This is a pretty deep program with alot of options which might be more than you wanted.
For freeware though, it has many functions although I'm not thrilled with the appearance-is a little odd IMO because it shows more than one function in a split window unless you turn that off, in 'options'. Defaults to a huge 'help' screen underneath whatever part of the program you have opened-mixer, composer, tablature etc. I also use a program called 'midi sheet music'. Again freeware but does not allow for recording your input-only plays back midi files in standard grand staff notation, but good for studying piano compositions-shows notation with or without letter names, can slow down tempo easily for practicing. Very simple and small program, in case you are interested. I am using it to study classical piano pieces most of which are in the 'public domain'-free to use for educational or personal use.
