Sorry to answer so late, too much to do

You could have checked out the SVN repository, but I made a package of the customized V-USB for you. I recommend diff to see the changes to your files

OK, I got it and it works on XBox1. I modified interrupt in endpoint 3 (acting as endpoint 2) to send up to 27 bytes, with 4 bytes CRC and sync that makes 31 bytes transferred. Now I'm using bit 6 for ready signalization on usbTxLen3, before 4 was used. As USBPID_NAK is used for this purposes which ...

And, as you have noticed, we encode other info in the length. So the maximum is probably 31 bytes unless you introduce bigger changes. This is hard thing, to find all instructions that use the length bits. In regards to "Did you investigate whether any host side driver accepts bigger packets? ...

Because it is 22 bytes long...

Hi! I want to modify the V-USB code to allow my device to send more than 8 bytes in one packet. I know it contradicts the standard for low-speed USB devices but other things also work which shouldn't. I know that the buffers are to small, but that's changeable. It's also perfectly possible to supply...

First, why is there the whole concept of endpoints? Let me explain, I believe endopoints are there to differentiate between different transfer types and in-out transmitions. But is this so? Or is there any deeper enpoint meaning I am missing? Becouse, for example, Control endpoint0 is In-Out, so wh...

Got all analogs on the xbox in windows, but not XBOX its self. Not sure what to try next I was hoping this would do it. As I wrote in the other thread I got this some time ago. This is working if the max packet sizes conforms to the standard by being 8 and the report is splitted into packets of 8 a...

This is my configuration descriptor: I see you have a default, 1 end in and 1 end out. Maybe I'm counting this wrong. So you have: 0 - default 1 - in end 2 - out end and you set your USB_CFG_EP3_NUMBER to 2 which means 1 if you count from 0. No, in my XBox configuration descriptor I have the defaul...

18 + 7 * USB_CFG_HAVE_INTRIN_ENDPOINT + 7 * USB_CFG_HAVE_INTRIN_ENDPOINT3 + 9, 0, /* total length of data returned (including inlined descriptors) */ I think this is wrong, as you got an additional output endpoint, so you got to add 7. I also tried using sendDataUSB3 on the PC with maximum packet s...

I hope you get it working with this information. I know the UPCB and got the XBox vendor request from there, but the XBox won't accept the setup I described Looking forward to your answer in the other thread

I got it working for the XBox mode of the Dual Strike project. See these files: ⋅  usbconfig.h ⋅  descriptors.c , see the XBox part. ⋅  xbox.c , the data is sent at the bottom with "sendDataUSB3()". ⋅  usb_controller.c , here "sendDataUSB3()&quo...

Sorry, I don't have the time to give you a step by step explanation, but I got it working on Windows with Cygwin (gcc and libusb required) and the compiler flag "-mno-cygwin", see the Dual Strike bootloader's Makefile.windows. Hope that helps

I suppose it should make a bit of a difference, as there would be only 4 USB interrupt requests (3x8 bytes and 1x6 bytes) plus it saves time and space on the MCU. And the parsing on the host side is a bit easier, but this should make no real difference.

Hi and thanks for discussing this matter, your conversation was of some help to me I'm trying to create a XBox controller on an ATmega168 using V-USB and got to the point where the XBox is getting input, but not all of it. I'm sending the 20bytes of the report through the interrupt in endpoint (eith...
