my Orange Pi A20 does not detect any USB device with the current versions of Stretch or Bionic, but works fine with Wheezy
I had try with a printer, a scanner, or USB stick. When something is connected, nothing appears in dmesg or lsusb.
Yes...yes...I've been reading the troubleshooting FAQs and Google it for an answer.
Change power supply and SD card, etc.
But a printer or scanner doesn't consume too much power from the USB, does it?
in a last effort I went back to the old Debian Wheezy (downloaded from orangepi.org) and everything works fine.
Any help with that?
Could it be a kernel parameter or module?
