Today I included 2 Renesas USB boards to try 7 cx231xx A/V recording devices on the same server. It worked for around 10 min and them I got the following warnings: May 20 14:57:39 video3-df kernel: [ 1004.311844] xhci_hcd 0000:04:00.0: WARN Set TR Deq Ptr cmd failed due to incorrect slot or ep state.
