Older DWC3\nprogramming guide revisions recommended setting forceRM=1 when\nissuing EndTransfer. Newer programming guide revisions recommend\nissuing EndTransfer with forceRM cleared.\n\nWith forceRM=1 on DWC_usb31 v2.00a and v2.10a controllers, a transfer\naborted through the ep_dequeue path was observed to remain active\nafter EndTransfer completion. A subsequent StartTransfer issued on the\nsame endpoint triggered writes associated with the aborted transfer.\nThis resulted in an SMMU fault because the transfer buffer had already\nbeen unmapped during EndTransfer command-completion cleanup.\n\nUsing forceRM=0 eliminates the issue. Although older DWC3 programming\nguide revisions recommended setting forceRM=1, no issues are known\nfrom using forceRM=0. Clear forceRM when issuing EndTransfer to provide\nconsistent EndTransfer behavior and align with newer programming guide\nrecommendations.","state":0,"publishedAt":"2026-09-16T10:33:31.801+00:00","modifiedAt":"2026-10-21T12:49:31.009+00:00","affected":[{"ecosystem":"Vendor
