I think "USB_RX_USER_HOOK" is what you are looking for. Once the device has been found by the PC the PC will keep communicating with it, so if you put a timeout after the USB_RX_USER_HOOK you can detect if the PC is running and knows the device is there. I am also looking to detect if the...

Hi, i want to send more usbSetInterrupt in a row. void log_usb (unsigned char ch) { while (!usbInterruptIsReady()) // check if USB int is ready { wdt_reset(); usbPoll(); } memcpy(&replyBuf[0], &NewLogCharAvailable, sizeof(uchar)); // copy report id to replybuffer memcpy(&replyBuf[1], &am...

So I got it to compile, and be recognized by my computer.

Hi!
I also got it compiled in AVR Studio but NOT recognized by my computer!

I changed the text address to 0x3800 for the Atmega168. Nothing else.
What did you change that the device get recognized?

Also I have a problem with bootloadHID and (pgm_read_byte_near(0x0000) == 0xFF) Device programming finished! Reset Device now, please wait... Device got removed: HIDBoot DeviceArrival: HIDBoot, VID: 5824, PID: 1503 I can program the device and than the function leaveBootloader(); will be called from...

Is there now an example how to combine an v-usb project with the bootloadHID?

Hi, I just tried the description from above with the hid-data example. I modified: #include "usbconfig.h" #include <hidpi.h> #include <hidsdi.h> Installed WDK 710. Added pathes like above. Using VS2008 SP1 When I try to compile: 1>------ Build started: Project: NewConsole, Configuration: D...

Hi, I want to modify my descriptor! old: PROGMEM char usbHidReportDescriptor[24] = { 0x05, 0x01, // USAGE_PAGE (Generic Desktop) 0x0b, 0x01, 0x00, 0x00, 0xff, // USAGE (Vendor Defined Page 1:Vendor Usage 1) 0xa1, 0x01, // COLLECTION (Application) 0x15, 0x00, // LOGICAL_MINIMUM (0) 0x26, 0xff, 0x00, ...

Thanks for the reply! I mean the desccripton like here: http://s1.postimage.org/8Dbm9.gif It is not my AVR! My AVR will show something like "HID input device". Just an example! I get showed the right device name when I first connect the device to the host. Like "HIDKeys" with the...

Hi,

is there a sample how to change the shown default USB HID device name in the device manger.

I think it have something to do with USB_CFG_DESCR_PROPS_STRING_PRODUCT or something like this.

Is there a small sample just to change the shown USB device name.

thx!

Here I have some log and the AVR source! I use the same functions like the HID-Data example. On one USB Port it is working fine, on the other: 20:43:08 usbhidOpenDevice faild, 0 .. .. 20:43:09 usbhidGetReport faild, 31 20:43:09 Polling faild, PollingFaildCounter: 1 31 is from GetLastError = Device n...

Hi, I were testing the HID-Data example. Now my project is almost over. But I have a problem with the init of the AVR. If the comunication of the device looks like this: http://s4.postimage.org/aOCnA.jpg The comunication, reading/writing eeprom, polling the device is working without any problems. Wh...

As I found out the report number is the Report ID. I have now this usbFunctionSetup function: /* ------------------------------------------------------------------------- */ uchar usbFunctionSetup(uchar data[8]) { static uchar replyBuf[7]; usbRequest_t *rq = (void *)data; usbMsgPtr = replyBuf; if((r...

Hi, I translated the code now to D2010. It's working! But one more question! Waht is the "reportNumber"? int usbhidGetReport(usbDevice_t *device, int reportNumber, char *buffer, int *len) { BOOLEAN rval = 0; buffer[0] = reportNumber; rval = HidD_GetFeature((HANDLE)device, buffer, *len); re...
