Just ordered one off eBayIf a problem is suspected with device power draw (a perch card power output issue) having a powered USB hub would mean hub connected devices would would not pull USB power from the perch card USB port (instead from the hub's power supply). Might validate the data/signaling portion of your work is right?
Fingers crossed it helps with debugging!Just ordered one off eBay
Have you tried to see what happens if you press the power button on a USB keyboard that has one?Anyone else going to have a go? There’s also the soft power circuit to look at if anyone’s keen.
Yes — nothing.Have you tried to see what happens if you press the power button on a USB keyboard that has one?
Definitely tempted!! Do you have a cheat sheet with everything that's needed?Anyone else going to have a go?
Yes - the last version of the schematic I posted on here, on page 10 I think, but it needs updating again. I could put together a Mouser BOM for anyone interested.Definitely tempted!! Do you have a cheat sheet with everything that's needed?
Yes, sure, we could work out a deal on this....and would you entertain providing an "upgrade" service?
