Hi,

I just tried my new RPI4 board and it seems to work fine the same as my old
board. I just observed that the problem is when my VFD (vacuum fluorescent
display) device is connected to either of the two USB 3.0 ports, this
device having uplcom(4) driver is not detected. It's a Prolific USB-serial
device having PL2303 chipset. However, when plugged-in to USB 2.0 ports,
this device is detected and functioning. I can send characters with the
echo command and redirect it to /dev/cuaU0 for display without any problem.
Other observations when this VFD device is connected to either 3.0 ports,
the 2.0 ports will not function i.e. plugging-in any USB devices like my
keyboard or my EMV reader. When this device is also connected to either of
the 2.0 ports, the other 2.0 port is functioning for other USB devices
while 3.0 ports are not. I attached two dmesg outputs when the device is
detected with 2.0 ports and undetected with 3.0. I also include kldstat and
usbdump.
