up squared board g_mass_storage not reliable and can not work at superspeed

harry123

I'm having trouble with g_mass_storage on UP Squared Series board

CPU: Intel(R) Celeron(R) CPU N3350
Memory: 4GB
OS: Ubuntu 20.04.4 LTS
kernel: Linux upboard 5.4.0-1-generic #0~upboard5-Ubuntu SMP Fri Jan 7 11:53:57 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

I tried to insert g_mass_storage module with the command:
sudo modprobe g_mass_storage file=/dev/sdb stall=0 iSerialNumber=123456

It only works as 480Mbps device when plug into a superspeed usb port, and having trouble when plug into some of the superspeed+ port.

Anyone have used g_mass_storage module at 5Gbps or higher?
