Hello USB developers,
I’m using an NXP LS1046A SoC with the integrated DWC3 USB controller in
host mode. On Linux v5.5.167 my USB flash drive was detected and mountable.
After upgrading to Linux v6.6.110 the USB flash drive is no longer
recognized. If it is already plugged in during boot phase I get the
following errors:
xhci-hcd xhci-hcd.2.auto: Error while assigning device slot ID: Command Aborted
xhci-hcd xhci-hcd.2.auto: Max number of devices this xHCI host supports is 127
And here is the kernel debug output:
user@host:~# cat /sys/kernel/debug/usb/xhci/xhci-hcd.3.auto/ports/port01/portsc
Powered Connected Disabled Link:Polling PortSpeed:1 Change: Wake: WDE WOE
I’ve also found that the function `xhci_alloc_dev` shows the error message.
I printed the `command` member variables and see that the `status` is
`COMP_COMMAND_ABORTED` and `slot_id` remains `0`. I have already seen
similar error patterns in some forums, but the suggested solutions didn’t
help me. Between these releases Kconfig has changed significantly; I may be
missing a config option, but I haven’t found one. Does anyone else see this
error pattern? Or maybe someone has a hint for me on how to proceed?
Best regards
Alexander Wilhelm

Or maybe someone has a hint for me on how to proceed? Looks like "enable slot" commands times out, This is a simple internal xHCI command which shouldn't timeout Could you enable xhci and usb core dynamic debug and share full dmesg after issue is seen. mount -t debugfs none /sys/kernel/debug echo 'module xhci_hcd =p' >/sys/kernel/debug/dynamic_debug/control echo 'module usbcore =p' >/sys/kernel/debug/dynamic_debug/control < Reproduce issue > Send output of dmesg Reasons for command not completing could be xHC being stopped, not processing commands due to being suspended, or something preventing xchi interrupt, and driver misses the command completion event Is runtime PM enabled fo xHCI in your DWC3 setup? It was enabled by default in 6.1 kernels for PCI based xhci 1.2 controllers. Does your flash drive enumerate if you first force roothubs on, disabling runtime pm? echo on > /sys/bus/usb/devices/usb*/power/control Thanks Mathias ^ permalink raw reply [flat|nested] 7+ messages in thread

No event for aborting the ring ether. Maybe interrupts from this xHC aren't coming through. Or then something in xHC isn't set up properly when command is queued. Could you add xhci tracing, and dump the command and event rings after timeout?

It shows the enable slot command was correctly queued to the command ring at 0x86616000, but xHC controller didn't process it at all as event ring is empty. It behaves as if xHC isn't really running at all. portsc registers can show port status (connect) even if xHC isn't running. I guess next step would be to bisect this and find the offending commit Thanks Mathias ^ permalink raw reply [flat|nested] 7+ messages in thread

I used the `stable` kernel repository and narrowed it down to the following commit: 136975c33894e7b48a6007af0f4c25f423bbd1de arm64: dts: ls1046a: make dma-coherent global to the SoC As it turns out, the problem was not directly related to the USB subsystem, but rather to the DMA changes on the Layerscape platform. When I revert this commit, USB works perfectly on my system. I have now CC'ed the `linux-arm-kernel` mailing list as well. Maybe someone has seen a similar issue and could provide some guidance.
