[VisionFive 2] USB: keyboard and mouse do not work if both connected

Description (last modified by )
This is hrev57062.
Only keyboard or only mouse connected works, but not together. Connecting multiple USB mass storage devices (3 USB drives and one mouse) works. If MSI-X is not enabled for XHCI, one of 4 USB ports (upper left) is not working.
USB support is implemented with VL805 chip that is connected to PCIe bus and provides 4 USB ports version 2 or 3. It implements XHCI interface and have 5 internal USB ports. Port 1 is connected to internal USB 2 hub that is used for USB 2 devices support. Ports 2-5 are USB 3 ports and connected to external USB ports 1-4.
Problems summary with VL805 chip:
- Interrupt endpoints with 2 or more devices at the same time is not working. Bulk endpoint work fine with USB 2 mode (mouse and 3 USB mass storage configuration work fine).
- Only 2 of 4 USB 3 ports are powered on (ports 2, 4: OK, ports 3, 5: not working).
- USB Mass storage devices in USB 3 mode work unstable and trigger errors "Babble detected", "Device FIFO overrun".

Did this device work previously? When did it stop working?
comment:4 by , 18 months ago
KERN: usb_disk: receiving the command status wrapper failed: Operation timed out
After this happens, a "reset recovery" should take place which cancels queued transfers, resets massbulk, etc. I don't see that happening in these logs?

usb error control pipe 9: timeout waiting for queued request to complete usb xhci 0: transfer error on slot 1 endpoint 1: Length invalid usb error xhci 0: TRB 0x4124d000 was not found in the endpoint!
A full log with all tracing enabled in the XHCI driver would be helpful here. I have a hunch these errors are occurring upon invocation of the "stop endpoint" command, which merely indicates the TRB had no data transferred to it yet, but I would have to read the spec and other drivers to determine if that is the case.
That pushes the problem up a level, though. It means the hub is just not returning any data to the controller. That sounds like a problem.

Just a simple USB to MicroSD adapter with a MicroSD card inserted. Never had any trouble with it before (but unable to provide bisect hrev ;-) )

On Linux there are 2 root hubs for XHCI: for USB 2 and for USB 3. It are populated based on XHCI_SUPPORTED_PROTOCOLS list (https://github.com/haiku/haiku/blob/17d9a20c621ba91b24b265a0c1becde9492be4c0/src/add-ons/kernel/busses/usb/xhci.cpp#LL638C19-L638C43).

"Embedded Hubs" seem to mean ones in the device but on on the XHC. "Integrated Hubs" seem to be ones in the XHC itself but not the root hub, so I guess that is what is happening here.
There is some information in the spec about "Tier Mismatch" occurring and also the "Integrated Hub Implemented" flag. I guess we should check what other OSes do to handle those.

Have you tried:
- hacking in a mechanism to the XHCI driver to ignore the USB2 ports?
- enabling full tracing, and seeing what differs under MSI-X?

Has anyone tried using a Logitech USB dongle that controls both a keyboard and mouse from the same dongle? I mentioned this, but it was theorized that it would not work (as it reports two devices), but has anyone actually tried it? If it's a physical limitation (you simply cannot use two ports (one per device; mouse and keyboard)), then this should solve it. If it's an interpretive (software) limitation, then this probably won't work. But it's worth a shot.

This patch help a bit, but do not fix root problem.
I'm seeing other stall regressions on x86_64 with usb_disk's (usb flash)
