cr1901_modernxobs: Does valentyusb work on Windows 10 on your machine?15:29
cr1901_modernActually, scrap that... this seems to be a problem w/ _florent_'s fork15:41
cr1901_modern_florent_: The litex-hub cdc_eptri branch of valentyusb will not enumerate on Windows. I have a USB capture I can give you from my Beagle, but I can't commit much time to this other than that15:42
cr1901_modernLooks like the core is not sending the full config descriptor after the third time windows requests it15:45

_florent_cr1901_modern: having the capture will be useful yes but I'm also not sure I'll commit much time to it (I just did some changes to Greg's branch :)), it has been working fine on Linux but haven't tested it on Windows15:47
_florent_cr1901_modern: this is a bit hacky for now, long term plan is to switch to Luna or rewrite a minimal USB ACM core15:49
cr1901_modern_florent_: Alright, just as a sanity test, I tested my TinyUSB Bx, which enumerates fine. Windows is sending more-or-less the same setup packets in the same order15:51
cr1901_modernIncluding the one where Litex chokes15:51
cr1901_modern_florent_: Do you have a Beagle? If not, I'll give you a CSV file of the capture instead of the database15:52
cr1901_modernhttp://ix.io/2KQn Anyways, here's a CSV15:54
cr1901_modernvalentyusb dies at "Get Configuration Descriptor,Index=0 Length=265". It only sends 9 bytes back instead of the full 62 bytes15:55
cr1901_modernAnd yes, that Length=265 also happens with TinyFPGA Bx. But Bx responds with with its full 67 bytes of descriptor15:56
cr1901_modern_florent_: I think if you send back the full 62 bytes of descriptor in response to that third "Get Configuration Descriptor" request, things should work15:57
