Hi Saimon, welcome back that is great news!
I for one would love to see what you have done and i'm sure I can speak for others.

Sounds like you are not adding the necessary paths to include directories. Go into configuration options and add the path to usbdrv along with ./ & ../(the current directory and parent). If you're still stuck then why not take a look at the avr-cdc project as it comes with avr studio project fil...

What error messages did you get?

As far as I am aware, the driver splits all control transfers (function read/write) into 8 byte packets regardless of the payload. Maybe you need to use an interrupt endpoint?

Sorry, i'm really not sure what you are trying to do.

Sure, by using HID feature reports. Try out the HID-data example, hopefully it will answer the rest of your questions and does pretty much what you're asking already.

Sorry, I've not gotten hold of an xmega yet or I would gladly give it a shot. However, looking at the spec sheet I am confident that the xmega is easily capable of running a software usb stack. So I guess the only question is whether V-USB will compile and run without too much modification. Since th...

Ah yes I think I meant to say supply Unfortunately, a 3.3V supply rules out a good number of AVR8s for F_CPU After looking over the datasheet linked in your OP, I have been wondering if the following setup might work: Operate the MCU from the 5V from the USB port and feed the 3.3V pin on the USBUF0...

All you need is provide a 3.3V signal to it. Certainly looks interesting but doesn't it also require a 3.3V supply? If so then we still need to use a LDO regulator or series diode voltage drop. However, given all the added bonuses like EMI & ESD protection it is probably well worth considering ...

Am I doing something wrong, or is this as specified? Yes, the 250 ms delay in an interrupt service routine is a BIG no no, regardless of the fact that the you must call usbPoll() at least once every 50 ms. Better increment a (volatile)global counter and toggleGreen every so many iterations. Hope it...

Is this possible to make a c++ project with libusb? I have done so with MSVC++ like this extern "C" { #include "opendevice.h" } usb_dev_handle *m_Handle = NULL; Where opendevice.h & .c are taken directly from the v-usb custom class example. The device is initialized like so ...

Hi 1. Does V-USB allowing "real time" communication of an uC with the computer via USB? That depends on what you mean by 'real time'. From a technical point of view the answer would be no, however from a user's perspective it could possibly be considered as such (think: keyboard/mouse). Re...

Just a wild guess, since it is a mass-storage class device, the actual splash animation may well be an executable file stored on the drive itself that gets 'autorun' on connection. I doubt very much this will be possible for any V-USB device regardless.

On jvHid is more example . If use this example then can find and see information for all HID devices connected in System (VID , PID, serial number ...) but how use it for read and write data in to MCU ???? Is there not also an example of how to read/write? I do not use Delphi myself nor do I have a...

You can also use the ones listed here: http://www.lvr.com/development_tools.htm . Scroll to the bottom of the page and be sure the read the terms carefully. Alternatively you could consider purchasing a licence for V-USB, see: http://www.obdev.at/products/vusb/license.html

Perhaps you will get a better reply on the Delphi forums. Working example code has been provided which can be compiled under MinGW or even MSVC (with a few tweaks). The biggest problem I think you will face is finding a compatible version of the Driver Delevopment Kit (DDK) required to compile the H...
