Kernel delay booting with USB + Serial RGB Backlight Charac

[xibeaga]

Hi!

When I plug in "USB + Serial RGB Backlight Character LCD Backpack", my kernel

Linux A 4.14.0-3-amd64 #1 SMP Debian 4.14.13-1 (2018-01-14) x86_64 GNU/Linux

delays the boot REALLY LONG.

[ 5.100088] usb 1-1.1: new full-speed USB device number 3 using ehci-pci
[ 5.209108] usb 1-1.1: New USB device found, idVendor=239a, idProduct=0001
[ 5.209117] usb 1-1.1: New USB device strings: Mfr=0, Product=1, SerialNumber=0
[ 5.209121] usb 1-1.1: Product: Adafruit Industries
[ 37.043282] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)

i use a mSATA disk, a Quad-Core AMD GX-412TC SOC cpu and 2GB RAM

Without USB LCD it boots like hurricane

Can you help me?
Thanks a lot!
Best regards,

This Ubuntu bug describes similar symptoms (though not with that device). It appears Linux gets confused with certain USB devices, perhaps due to particular USB controllers as well: https://bugs.launchpad.net/ubuntu/+sour ... ug/1437492
