I'm a fairly new RasPad owner, I've had mine for a couple weeks now. I've discovered a fairly major difficulty with the unit. It won't recognize certain USB sticks plugged into any of the 3 USB 3.0 ports on the side.
And by certain, I mean USB sticks that are rated for 3.0 speeds. Older USB 2.0 rated USB sticks show up just fine. I have looked for evidence of these drives using both the lsblk and lsusb commands. They don't show up anywhere, although like I said, older USB drives show up just fine. I have tried this in multiple operating systems: Raspberry pi OS (32 bit & 64 bit) and Ubuntu Desktop 21.04 (64 bit). I get exactly the same response in all of them. All other USB devices (mice and keyboards, etc) seem to work just fine.
Strangely, when I have an official Raspberry pi keyboard plugged in, I can plug in my newer USB drives into the USB hub on the back of the keyboard and then the system will recognize it. I assume that's because the USB hub on the RPi keyboard is a USB 2.0 hub.
Has anyone else had these issues? Is there a fix for this? This seems to be a moderately large issue.
Please let me know.
