So from that, what is one to conclude?
a) Everyone's USB 3.0 works fine?
b) Nobody cares?
c) "3.0" doesn't search correctly?

z) something else?

Re: v-usb with usb 3.0?

It's also hard to find information on this because the current configuration of this phpBB does not allow "3.0" as a search term. Perhaps an adjustment is in order?

v-usb with usb 3.0?

I have built several devices with v-usb, and tested on hundreds of computers. I have only found three usb ports which did not recognize my v-usb devices, and it turns out that all three of them are USB 3.0 ports. Are there known problems with 3.0 vs v-usb? Is there something to be done? I have not y...

Re: HID read speed?

Well, it certainly does help to RTFM, doesn't it? I simply changed USB_CFG_INTR_POLL_INTERVAL from 100 to 10, and all is well.
Sorry for the intrusion.

HID read speed?

I am creating a new HID device to deliver real-time data to a PC (or Mac). I have used a template for a game controller with a single slider and no buttons to get the smallest report descriptor: PROGMEM const char usbHidReportDescriptor[24] = { 0x05, 0x01, // USAGE_PAGE (Generic Desktop) 0x09, 0x05,...

Re: HID-Data problem with one host (works with others)

OK, This is getting weirder and weirder.

I added the HID bootloader to my device, and now, even though the main program still fails on this one PC only, the bootloader works fine. That, I would think, pretty much eliminates any hardware problems.

So now what?

Re: main.c on v-usb

Oh, you really do need to do some reading about the C language before you go any further. Particularly, your question about the two len variables points to a lack of understanding about a variable's scope. There's plenty of tutorials on the web, or you can get any number of books. But you're going t...

Re: main.c on v-usb

uchar is how some compilers designate an unsigned char, equivalent to winavr's uint8_t.

Does that help?

HID-Data problem with one host (works with others)

I'm using the hid-data sample on a Mega644 (16MHz), and I've run into a problem. I've tested this with at least ten different computers, ranging from a netbook to an i7-980X. Everything works OK, except for computer, a 3.2GHz i5 running XP. On the problem machine, my board enumerates OK and I can se...
