USB Hub with v3 Board?
I have been trying to use a small USB hub to hook up both a keyboard and mouse to a v3 board and I'm never able to get anything to show up. Am I missing something?
What you can plug into HID Remapper
Wireless receivers are supported and multiple devices can be connected at the same time using a USB hub (with different mappings for each device if desired).
I tried 3 different hubs, none worked, do you have a specific model that you have been successful with??
Hubs with the FE1.1s chip should work, for example: https://www.waveshare.com/usb-hub-hat-b.htm
Also CH334 I think.
For the dual Pico variant also the SL2.1a chip works, it's what the variants with a built-in hub use.
I don't really understand why even the dual pico variant is so picky about hubs. I tried the cdc_msc_hid example from TinyUSB, picked three random USB hubs from my shelf and connected them all in a row between input devices and a pico (RP2040) without any issues, everything worked as expected. Maybe it was just luck, or I am missing something?
Should work the same. For some hubs the order of plugging things in matters (plug into HID Remapper, devices into hub, HID Remapper into the PC).
Or maybe some recent changes in TinyUSB improved things - the version used in HID Remapper lags a bit. Need to test.
Here's a test build with TinyUSB updated to the latest version. Feel free to try it and see if it affects hub compatibility.
