I seem to remember something about the pico chips causing issues. My advice would be to try a atmega8/168/328 and see if it works. If its the chip then you may have to email Christian.

Thanks for that tip. But I have the same reason, Windows doesn't seem to like my descriptors. I'm using an ATmega644pa too. cialis

hanks for that tip. No change though. Windows doesn't seem to like my descriptors. Haven't modified any of the other files. I'm using an ATmega644pa, btw. buy cialis now

Well, I'm not going to steal the touch from EnigmaticManiac but I will offer help if you need it. I have used all of Ralf's project and added a lot of features to them.

Here is my project if you are curios
http://bliss-box.net/Bliss-Box/new.html

Ralf has been MIA for some time, I hope all is well he was a great mentor.

Why woudl you not want to use Ralhp's ? His adapters are some of the best around.

I am attempting to, I am having trouble with it so I was wondering if the OP had any suggestions or made any changes to get it to work.

Hey Enigmatic, did you use the schematic from http://www.raphnet.net/electronique/sne ... dex_en.php? If not, would you mind sending me your schematic and source code? I am interested in putting something like this together too.

USB enumeration happens as soon as you connect the resistor from D- to VCC. So if you remove the chip you'll still get a enumeration failed error.

So if the VID/PID pair isn't found then the chip isn't communicating with the host yet. Which could be one of the following:

Wrong fuse settings (internal RC configured when you need to use an crystal, DIV8 setting in ATTiny2313)
Mismatch in crystal frequency and F_CPU.
Bad wiring, wiring USB cables directly to my board has caused me some grief. Try a very short USB cable. I also managed to switch around power and ground once...
Wrong pin/interrupt settings in usbconfig.h
Not calling usbPoll() fast enough (or any other general bug in your code) try loading the hid-mouse example. Which doesn't require any additional hardware and should tell you if your USB hardware is working.
No code is running in the chip. Crystal not working, power not connected, try a blinking led example. (Even without a LED you should be able to use your logic analyzer to see this pin working or not)

USBlyzer tells me that Enumeration of device failed.

DN_REMOVABLE

DN_NT_DRIVER

Manufacturer:(Standard USB Host Controller)
Friendly Name:

PDO Name:\Device\USBPDO-5

Also, for shits, I changed the chip to an ATmega16a, no change. Assuming the code isn't wrong, what else could cause this kind of error, where the device doesn't even get past the first stage of enumeration?
