mithroCarlFK: did you see https://www.crowdsupply.com/capable-robot-components/programmable-usb-hub ?21:08
tpbTitle: Programmable USB Hub | Crowd Supply (at www.crowdsupply.com)21:08
CarlFKmithro: hmm.  neat, but not sure what I would do with it21:12
mithroCarlFK: It could work as part of your CI system21:13
mithroLets you programmatically connect / disconnect USB devices21:13
CarlFKmithro: I still need to power cycle them - not sure what good it would to to turn the usb on/off21:14
mithroCarlFK: You can test connecting / disconnecting the USB...21:14
mithroCarlFK: Should be able to also reliably see the opsis / atlys doing the disconnect / reconnect dance21:15
CarlFKmithro: I could, but I'm not sure that's a thing we need to worry about21:15
mithroCarlFK: I also picked up a bunch of OpenVisla devices to work with Kate's USB decoder thingy21:15
CarlFKis that the thing in the teardown usb video?21:16
mithroIt's one of the things21:16
mithroGot it more for the Fomu related stuff21:16
mithroBut it could in theory help with fixing / improving the FX2 stuff21:16
CarlFKAndy at PS1 has one - I can borrow it for a while right now if it would help anything21:17
mithroCarlFK: Not unless your are finally going to get your hands dirty with fx2 C firmware hacking21:18
mithroCarlFK: I pushed the conda fix which should mean the prebuilt repository should update in the next 24h21:19
CarlFKmithro: thanks.21:20
CarlFKmithro: I may have picked a bad time to try and test firmware builds, but trying to test my red/orange blank screens was my typical frustration of having no idea what I should be doing/reading/anything21:21

mithroCarlFK: I have some time right now to look at your udev issue...22:04
CarlFKmithro: woot!22:04
mithro(Only reason is that I'm not feeling up to doing real work...)22:05
mithroCarlFK: were did you put the udev but?22:06

mithroCarlFK: The only way I can see https://github.com/litex-hub/litex-buildenv-udev/issues/3 happen is if you have some type of bad udev rules...22:22

CarlFKmithro: what about usb hubs?22:23
CarlFKmith:  a guess given a box with no hub looked ok22:23
mithroby-serial/<missing>/tty is what I'm looking at22:23
mithroHub won't have any affect on that22:23
CarlFKmithro: did you see my ssh pm?22:30
mithroHow did you install the udev rules on this?22:31
