[Rfdump] com port

[Stefan Kelm]

Hi,

I've stumbled over the very same problems as Denis: initially the ACG
reader (ACG DualISO USB) worked fine both within the VM live image
as well as with the Windows tools as provided by ACG
(e.g., ReaderUtility.exe).

Now, I'm no longer able to connect to the reader using RFDump v1.4. Even
using a plain SUSE 10.1 workstation I can't connect ("reset resulted in
nothing") at all. ReaderUtility.exe under Windows still works fine,
though.

Would it be possible that the firmware somehow got corrupted (how would
I tell?) or is RFDdump unstable as of yet?

Cheers,

	Stefan.
