USB 3.0 SSD and Flash disk unstable and disconnect


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?


Could you share the dmesg? Also, what is your usb drive? Please share brand names.

Dear Wayne

USB Flash Memory
transcend - JetFlash 920 [ts128gjf920] 128GB USB 3.2 Gen1

RAOYI - Model:X4 removable SSD 120GB USB3.1 Gen2

installed Jet Pack 4.5.1 from Recovery mode(SDK Manager)

initial settings and rebooting, connect the USB3.0 SSD and format GPT Partition.
Default setting Benchmark result

install(SDK Manager) (119.1 KB)
dmesg (65.5 KB)

Was self resolved. Thank you for your help.

Can we can know how it’s fixed? What the cause is?


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

Good, thanks for your sharing.
