Subject: [Bug 218890] reset SuperSpeed USB device number 2 using xhci_hcd
Date: Wed, 29 May 2024 15:39:04 +0000 [thread overview]

--- Comment #9 from Mathias Nyman (mathias.nyman@linux.intel.com) ---
Traces show xhci driver sets the length of the cancelled 512 byte bulk transfer
incorrectly.
I'll attach a patch for that.
The 255 byte control transfer case is not that clear.
It stops on the data stage with a 'stopped' completion code, with 'len' field
indicating residual untransferred bytes is 0.
827.939738: xhci_handle_event: EVENT: TRB 00000001511921e0 status 'Stopped'
len 0 slot 2 ep 1 type 'Transfer Event' flags e:c
827.939747: xhci_handle_transfer: CTRL: Buffer 00000001023cff00 length 255 TD
size 0 intr 0 type 'Data Stage' flags i:i:c:s:I:e:C
It's also unclear why these transfers don't go through
