I only have an HXD (and a GC) here. The HXD has bcdUSB as 1.10 unlike your TA with 2.00, but not sure that helps.Sound promising .. why do you think this is this not reliable?
Perhaps it is. Perhaps even bcdDevice of 3.00 is enough (includes some older variants that the TA replaced supposedly). Not sure anyone ever tried the current scheme on those older models. Charles, could you post the output of "lsusb -v" for your PL2303TA? And did you verify that you actually got 110 Bd with the current Linux driver? Johan
