Hi, I'd like to update my iScan HD with the latest software for the bug fixes and direct IR control, but do not have a USB port so wanted some adivce from others who have successfully updated. -I have a USB > RS232 adaptor but it isn't one of DVDO's suggested models, will trying it potentially cause damage. If it can't support the data rates needed, could I be left with a non-functioning scaler? -Does anyone know where to get one of the suggested adaptors for a decent price in the UK? Any help or advice much appreciated!!
