Sounds like broken usb drivers..
Give this image a quick test on a spare microSD card.

It'll take you 5 minutes to download, 10 to 'flash' to a microSD and 1
minute to verify.

Did you connect a monitor? What’s it showing?

Are they detected? What does lsusb return? Try dmesg to see if something went wrong. Do your keyboard and mouse work with the default drivers?
By the way, do the above using SSH. Hook up an ethernet cable and SSH into the board.

if usb is broken for him, eth0 is not going to be active, as it's
attached the smsc95xx 4 port hub (and ethernet) usb 2.0 device.
Regards,
Well, usb might not really be broken. It might simply be some weird incompatibility. If usb is really broken, trying to SSH would really prove that.

Not necessarily. But if you can manage an entry through ethernet, you can debug the issue.

Most of the time if usb flat out doesn't work, it's
sprz319e-2.1-erratum... Which a lot of the older images don't have our
workaround enabled by default.
Regards,
Okay. But, in this case, there’s pretty much nothing else that could be done, isn’t it?
The workaround is enabled in the image i linked too. If it doesn't
work with that image, the board is probally broken.
Regards
Board being broken would be my first vouch.
That’s because I have been using Ubuntu on the same board for a while, across several releases, and never did it fail to recognize a usb device. Most probably the board might be broken or the particular image downloaded might be tampered with (unlikely).
