cr1901_modern | xobs: Does valentyusb work on Windows 10 on your machine? | 15:29 |
---|---|---|
cr1901_modern | Actually, scrap that... this seems to be a problem w/ _florent_'s fork | 15:41 |
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 that | 15:42 |
cr1901_modern | Looks like the core is not sending the full config descriptor after the third time windows requests it | 15:45 |

_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 Windows | 15:47 |
_florent_ | cr1901_modern: this is a bit hacky for now, long term plan is to switch to Luna or rewrite a minimal USB ACM core | 15:49 |
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 order | 15:51 |
cr1901_modern | Including the one where Litex chokes | 15:51 |
cr1901_modern | _florent_: Do you have a Beagle? If not, I'll give you a CSV file of the capture instead of the database | 15:52 |
cr1901_modern | http://ix.io/2KQn Anyways, here's a CSV | 15:54 |
cr1901_modern | valentyusb dies at "Get Configuration Descriptor,Index=0 Length=265". It only sends 9 bytes back instead of the full 62 bytes | 15:55 |
cr1901_modern | And yes, that Length=265 also happens with TinyFPGA Bx. But Bx responds with with its full 67 bytes of descriptor | 15:56 |
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 work | 15:57 |
