Hi Bill,
I understood that if lsusb is empty then it is failure case, but you didn’t reply my question.
If it always has problem after reboot, then under what case would it works?
Please help share the following information
A. Does the issue also happen on the other M.2 external SSD?
B.The test result of the following steps
- repro the issue
- plug the device to PC
- plug the device back to galen
Does the device get enumerated on PC after repro the issue?
Does the device get enumerated on galen after step 3
C. The detail repro steps, including
1.Peripherals :
2. Repo Steps :
3.Test result :
4. Expected behavior :
5. Other information :
D.The kernel log with debug logs enabled
1.Repro the issue
2. enable kernel debug logs
echo 'module usbcore +p' > /sys/kernel/debug/dynamic_debug/control

Do you mean 3 NVMe SSD which are all the same from this pchome link? Do you have other kind of NVMe SSD?

We were not asking you to share the content of “control”. I meant adding those line to the control node and then share the dmesg
If lsusb hangs, can you monitor “dmesg --follow” in another terminal (or preferably serial console) and see if anything shows up as you run “lsusb”?
dear Wayne.
we use the other two NVMe SSD and same as issue.

Ok, please share the log with the method in #23.
dear Wayne.
We save log.txt(NVM SSD can be working) and log1.txt(NVM SSD not working before reboot)
Hi Bill,
Please be more active on forum. It has been almost 3 weeks since your last update.
We will help check the log and may still need your input.
Bill,
Sorry for one more question. All the link you pasted here is just the nvme to usb adapter.
What is the nvme device you are using?
