USB 3.0 SSD and Flash disk unstable and disconnect

Hi.

My jetson nano (JP4.5.1 B01) can not use USB3.0 Medias.

Rather than being unusable, the connection sends and receives data at high speed for a moment, but it freezes immediately, and then an error occurs and it becomes unrecognizable.

I tryed two types of USB SSD and USB Flash Memory, but both have the same symptom, and since the SSD is a Type-C connection, it can be used without problems when used with C to USB 2.0.

This USB device can be used on other PCs without any problems.

Is there a solution?

Dear kayccc

In my case it was a simple .
disable UAS driver

#get Dievice ID

$ sudo lsusb

#Find target device
#~~ ID xxxx:xxxx … ~~ Driver=uas

$ sudo nano /boot/extlinux/extlinux.conf

APPEND ${cbootargs} quiet root=/dev/mmcblk0p1…
↓
APPEND ${cbootargs} usb-storage.quirks=xxxx:xxxx:u quiet root=/dev/mmcblk0p1…

sudo reboot

It can boot even if install L4T on USB3.0 SSD & flash memory
