You appear to have a different device than the one Anton reported (e.g. PL2303GS instead of PL2303GC), but the fix is similar and was merged in March as I just mentioned in my other mail. > (forgive the basic questions, I am not very experienced with linux so > don't know what bit I need to update to get the latest usb drivers - > or whatever it is you updated) Just make sure you update to a recent mainline or stable kernel (e.g. 5.17.2, 5.16.19, 5.15.33 or newer) or wait until your distro kernel catches up. The commit you need is 5b6ab28d0678 ("USB: serial: pl2303: fix GS type detection") if you want to report it to the distro. Johan
