Re: v-usb + hidapi

Try to change: unsigned char buf[9]; to: unsigned char buf[8]; Editted : because you " return 8 " in the device side while ' res = hid_read(handle, buf, sizeof(buf))' will return " sizeof(buf) " which is also 8, so the " res " will return negatif value as I knew. Add yo...

There's nothing wrong with your code as I tested it. Here's your code with little mod for my test ( you set the report out but you didn't use it ? ) : /* Name: main.c * Project: hid-data, example how to use HID for data transfer * Author: Christian Starkjohann * Creation Date: 2008-04-11 * Tabsize: ...

Re: GUI for Simple V-USB tester (Update4)

It was written in Delphi's, as it is easier than C#. I'm using libusbdotcom in my C# projects ( VS2010 ), but since it needs .NET Framework 4 for running the application, I decided to wrote in Delphi. I didn't intend to share the Delphi's full source code, sorry for that, but I'll try to answer your...

Re: uC seems to be communicating then stops

Hi Stefan,
Please post the full schematics of the AVR example project that you worked with, I'll try to post the hexfile to make sure there's no hardware issues.

Re: Zener diodes at D+ D-

Also, I power the uC from USB. I need to put a 0.1 uF in parallel to Vcc and Gnd. Put a 4u7 electrolit capacitor at USB Vcc and Gnd if you supply your uc with USB bus not 0.1uf. So, I’ve added a 500 k resistance between ground and D-. And it works!! That's very strange to do, you didn't have to do ...

Re: HID DESCRIPTOR more than 255 bytes

I think straight answer is better than wasting bandwidth told me to look for the "good example" which I didn't know which is "good" exactly because I'm new to this V-USB, and told me to try to use >255 then (which make me asking here in the first post), including "Microchip&...

Re: HID DESCRIPTOR more than 255 bytes

There is no trick, just do it. Like I said find a better example. Like what? Any link to it? I already told you its possible. Possible if less than 255 bytes (as I knew so far) Get one of the ever so common mouse or joystick examples. mouse or joystick examples only needs under 255 bytes, so that's...

Re: HID DESCRIPTOR more than 255 bytes

Sorry for my bad I'm not going to confused you with my code, as I'm new to V-USB and still figuring out how it works for my needs. That's why I took the working example to start, and try to understand it. I was asked to post my code here, so I posted it even it messed up because it's far from final ...
