Didn't seem to do anything new with the HHKB once I plugged in another device (a logitech keyboard). Damn sorry, there's a bit of code that detects if a device is already enumerated and won't enumerate it again. Latest commit fixes it and has a new feature - if you press the button it will …

I'm impressed you guys have the skill and patience to hand-solder 0402 components meant for automated assembly (ie., no enlarged "hand solder" pads)! I can only speak for myself but a microscope, good flux and A LOT of patience. this was only the 3rd SMD board I've ever built so I was trying to …

Even though I had a functional ITX board, I decided to make one from scratch and solder the components one by one. I always enjoyed building Eivind's art work piece by piece, manually.

Oh interesting, looks like it's just not able to speak to the device at all. My crappy hubs fail much later in the process. I had a look through the tinyUSB code and it looks like the only major thing it's doing differently is retrying the enumeration process several times if it fails. Apparently …

Aha, as we suspected it's a fullspeed device therefore won't be susceptible to the lowspeed issue. So there's no reason why your HHKB shouldn't work on the hidman if it works on other USB1.1 hosts (your RP2040). I suspect that is a bug in hidman. BTW, I've tested your RP2040 code on a pico board …

OH yeah, if you could get it working from the BIOS itself that would be awesome! certainly not a need of course just a cool feature. I love the idea of using the CM4 instead of the Zero 2 since it's a lot smaller and more powerful. Hopefully they become easier to get as I've had issues finding them …

Thanks for bringing up many interesting points, I'll go through each: Going over this, the MIDI out and Line in ports are surface-mount whereas the main output jack is through-hole. Was this done because of space constraints? For the first prototype, I just went with surface-mount jacks I'd used …

As a lover of these kinds of projects I will be watching this and the llamablaster closely! Any thought, or room for that matter, of adding the HDD clicker like on the ITX llama? I love that feature. It just makes it feel like an authentic experience. I wasn't planning on adding a hardware-based …

OK latest commit has hub info in the debug output. Note that if you haven't used the menu in a while the process has changed - you have to hold down the button for a few seconds to make the menu appear. Also pressing the button without holding it will cycle through AT/XT/Amstrad modes so be careful …

USB 1.1 devices can run in Low Speed (1.5Mb/s) or Full Speed (12Mb/s). USB2 devices have those modes too, but can also run in High Speed (480Mb/s). I would be interested to see if your keyboard is Low Speed or Full Speed. The keyboard reports being capable of FS, according to the screenshot below. …

You mean the code that's currently on main ? I believe I already tried, and it didn't work. But I'll do another test, just to be sure. Thanks, yeah current main code theoretically supports most USB hubs. make sure it works on directly-connected mice/keyboards first, possibly the code broke …

Actually, a better test would be to see if your USB2.0 hub/keyboard works on the latest hidman code. I have some USB2.0 hubs that work just fine, and yours probably is one of those. (EDIT - note that you'll have to have all devices plugged into the hub when you connect it to hidman, the code …

So I've done some more testing on various hubs and come to some findings. The problem only seems to appear when the following setup is used : USB1.1 low speed device ---> USB 2.0 hub --->USB1.1 Host (i.e. hidman or PC) Interestingly the same hubs that fail on the hidman also fail when connecting to …
