Haven't noticed this one myself. The only issue I hit once in a while

This might be the XHCI bug where there's missing error handling
around a controller reset failure. I have a patch to send to fix it.
I would second the please send the patch request. I've got a USB raid
enclosure I carried a patch for a few years similar to the one in this
discussion: https://edk2.groups.io/g/devel/message/58193
I've created a PR with the patch:

Hi, so that patch doesn't fix the USB/XHCI error I posted last week, and
that's largely because its not fixing the out of resources issues which
happen when the controller is repeatedly reset. Which itself is in
error, because the returned check condition is valid, but indicating the
device doesn't support the requested command. So the usb subsystem
should _NOT_ be repeatedly resetting, rather it should be trying to use
a different command, or simply ignoring the device since reset implies
there is something wrong with the device/communications channel. Which
isn't the case, the device is perfectly happy, its simply refusing the
requested command.
Also, I hit the MMC error again on the rpi, it seems to be a block size
overflow that isn't being handled correctly. The request is for more
data than a single write the SD card I have seems to support. So, then
it should be sending the remaining block, but its getting stuck sending
MMC_CMD13, presumably waiting for the previous write to complete, which
never happens.
