| ovf | so for a hub with just one tt, everyone should be able to see the traffic for the whole hub? | 00:12 |
|---|---|---|
| *** CarlFK has quit IRC | 00:14 | |
| xobs | Yes. That was an issue in foboot versions before 1.9. | 00:29 |
| xobs | They would respond to traffic destined for other devices. | 00:30 |

| ovf | oh wow! this cheap "usb 2.0" hub is actually full speed (i looked at bProductProtocol=0 in disbelief but it's really FS). didn't know i could still buy those. :-) | 01:32 |
| ovf | *bDeviceProtocol | 01:32 |
| xobs | That's technically USB 2, still! | 01:35 |
| ovf | also it's a tree of three 4-port hubs, but i guess that's to be expected | 01:36 |
| ovf | well, a very unbalanced tree, also known as a chain. | 01:37 |
| xobs | Christmas tree. | 01:59 |

| mobius__ | I'm playing with a Fomu on a Windows 10 host + Virtualbox Ubuntu guest OS. I've set up the guest OS according to the instructions with udev rules etc. Virtualbox passes through the USB device, but I get this error: "usb 1-1: device descriptor read/64, error -32". Any idea what is going on? dfu-util -l doesn't recognize because device had an error. | 19:35 |
| xobs | mobius__: if its an earlier version of Fomu, then it didn't properly support USB reset. That might be the issue. | 19:44 |
| xobs | 1.9.1 was the first version of foboot that supported that use case | 19:44 |
| mobius__ | xobs: it's the version you handed out today at the workshop | 19:44 |
| *** xkapastel has joined #tomu | 19:47 | |
| mobius__ | confirmed with windows utils that it's 1.9.1 | 20:26 |
| xobs | mobius__: hmm... Maybe try updating to 2.0.3? | 20:57 |
| xobs | Download https://github.com/im-tomu/foboot/raw/master/releases/v2.0.3/pvt-updater-v2.0.3.dfu and install it. | 20:58 |
| xobs | I don't know if that version of micropython will work, but you can try circuitpython instead. | 20:58 |
| xobs | I'm really curious to know if 2.0.3 works, and if it fixes the issue. | 20:59 |
| xobs | Circuitpython can be downloaded from https://github.com/xobs/circuitpython/releases/tag/v0.1.1-fomu | 20:59 |

| mobius__ | xobs: that fixed it. | 21:29 |
| mobius__ | so it was a problem with a soft reset when it did the USB feedthrough to the VM? | 21:30 |
| xobs | mobius__: thanks for testing! That's a good argument to push the new version. | 21:30 |
| xobs | Yes, the issue may be that the reset process wasn't correct. | 21:32 |
| xobs | It may have been fixed by https://github.com/im-tomu/valentyusb/commit/b262b994fd9e6568b257b8424fe808cfc403e652 | 21:32 |
| tpb | Title: eptri: use EventSourceProcess to signal usb reset · im-tomu/valentyusb@b262b99 · GitHub (at github.com) | 21:32 |
| mobius__ | xobs: Cool. It's both recognized and uploads w/ dfu-utils in the VM | 21:38 |
| xobs | Awesome! | 21:53 |
