First (USB users only) download libusb-win32 from here (I've used 1.2.5.0 but think anything not so old will do well). Then explode the libusb archive, in the bin/x86 folder you will find install-filter-win.exe. Connect the HP50g with USB cable and switch the calculator ON. Execute install-filter-win.exe, then choose install a device filter and click Next >. A list of USB devices will appare, choose your calculator and click Install, now the device filter is installed.
After installing the device filter on win7 I had no problem using the original connection software from HP but I cannot assure you that it will go right.
Second, download the archive containing the exe from here (16-09-2011 Updated for missing images problem), explode in the folder you prefer and run HP82240B.exe. I hope it will run smooth!
Will be available soon! give me the time to make it a little bit more readable.
