@geekmaster: Yup, still got that PW1 and that K4, thanks

. The PW1 was my main "at home" reader until the PW2 came out, and the K4 was invaluable as a dev device (and was the one that ended up accompanying me everywhere, until the H2O). The PW1 is currently between parenthesis in my device box since I've lent it to my brother, but it still there, alive and well

. The PW1 is still terrible compared to the PW2/3, but that's certainly not your doing

.
And, yeah, @knc1 is correct, there's a 'plugged in' check to avoid a various collection of weird issues. Depending on devices/FW combo, actual issues may only appear in one 'side' of the equation (i.e., etiher USBMS -> USBNet or vice-versa), so the check has to wrap both :/.
@knc1: I've always felt a bit iffy about donations in this specific context (I might have written a bit more about that at one point), so, no PayPal

. But if it were to happen, I'm afraid that, yeah, I'd need a "prebaked" version when it comes to serial ^^.
