I also hope to have a complete list of all HXN versions.. But it is difficult.. I use PL2303GT as an example. PL2303GT is currently divided into PL2303GT_R4 / PL2303GT_R5 / PL2303GT_R5+ PL2303GT_R4 : idProduct : 0x23C3, bcdDevice: 0x0300 PL2303GT_R5 : idProduct : 0x23C3, bcdDevice: 0x0305 PL2303GT_R5+ : idProduct : 0x23A3, bcdDevice: 0x0305 The above three kinds of PL2303GT are currently available in the market. >From the bcdUSB & bcdDevice of PL2303GT_R4, it is the same as PL2303TA. So it needs to be checked again with hx_status check. As mentioned earlier, some HXNs are currently on sale, and some HXN versions are coming out (bcdDevice will have other settings), HXN cannot use bcdDevice to determine the type one by one. Charles.
