Hi Mathias,
I am here on Linux-v5.11-10201-gc03c21ba6f4e.
I see a lot xhci-resets in my dmesg-log:
root# LC_ALL=C dmesg -T | grep 'usb 4-1: reset SuperSpeed Gen 1 USB
device number 2 using xhci_hcd' | wc -l
75
This is what I have:
root# lsusb -s 004:001
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
root# lsusb -s 004:002
Bus 004 Device 002: ID 174c:55aa ASMedia Technology Inc. ASM1051E SATA
6Gb/s bridge, ASM1053E SATA 6Gb/s bridge, ASM1153 SATA 3Gb/s bridge,
ASM1153E SATA 6Gb/s bridge
My external USB 3.0 HDD contains the partition with my Debian-system
and is attached to the above xhci bus/device.
Can you enlighten what this means?
Is this a known issue?
Is there a fix around?
BTW, in which Git tree is the xhci development happening?
Can you point me to it?
I am attaching my linux-config and full dmesg-log.
Also I have attached outputs of:
$ sudo lsusb -vvv -d 1d6b:0003
$ sudo lsusb -vvv -d 174c:55aa
If you need further information, please let me know.
Thanks.
Looks like that xhci-reset happens here every 10min.
