b3e40fc85735b787ce65909619fcd173107113c2 is the first bad commit commit b3e40fc85735b787ce65909619fcd173107113c2 Author: Oliver Neukum Date: Thu May 2 13:51:40 2024 +0200 USB: usb_parse_endpoint: ignore reserved bits Reading bEndpointAddress the spec tells is that: b7 is direction, which must be ignored b6:4 are reserved which are to be set to zero b3:0 are the endpoint address In order to be backwards compatible with possible future versions of USB we have to be ready with devices using those bits. That means that we also have to ignore them like we do with the direction bit. In consequence the only illegal address you can encoding in four bits is endpoint zero, for which no descriptor must exist. Hence the check for exceeding the upper limit on endpoint addresses is removed.
