Re: usb keyboard via hub on rpi 3a+

1. Does the first USB 2.0 hub, the Maxxter device with card reader, work correctly with Ultibo when the USB Keyboard/Hub combo is NOT connected? The maxxter does not seem to work ever but i dont have another device to attach to it. With or without the keybard the usb dump 'freezes' 2. Does the seco...

Re: WebGL

You need to write your own browser application i guess - so you need a javascript parser - you need to translate (gl.) webgl calls to opengles 2.0 calls - optional html parsing to get to javascript parts. As an exercise you could take a simple application that draws a cube and rotates that and trans...

Re: usb keyboard via hub on rpi 3a+

Tried the hub and keyboard combo on the rpi3b+ and get the same not working result. On both the rpi3a+ and rpi3b+ with only the usb hub attached the dump freezes. Cannot test this on my rpi2 or my rpi1 (broken/lent out). But i blame the usb hub and not the rpi revision. The usb hub however does work...

Re: usb keyboard via hub on rpi 3a+

As repetitive as i am unplugging and replugging keyboard and or hub does not help for my situation. I will try another pi later, but they are build into other projects so that is going to be a bit of a hassle. I managed to make an usbdump to file thingy and here is the output with only the keyboard ...

Re: usb keyboard via hub on rpi 3a+

The usb hub i use has 3 ports and also a sdcard reader part that shows up as usb storage. I fear my keyboard has an build in usb hub and the keyboard itself is connected trough that usb hub also (did not realize that, but makes sense). So in the end my keyboard goes trough 2 hubs, maybe ultibo stops...
