The UB960 and UB9702 have different registers for the purpose, and the UB9702 version is not correct. Each of the VC_ID_MAP registers do not contain a single mapping, as the driver currently thinks, but two. This can cause received VCs other than 0 to be mapped in a wrong way. Fix this by writing both mappings to each register.
