Hi,

Windows uses a FIFO sometimes there is some noise inside this FIFO, so:

0. Use Linux, you got native RFDUMP support, out of the box Debian 
packets ... etc... if you will wanna use Windows follow up.
1. Check if the com-port is connected.
2. Check the baud-rate of the port.
3. Check you got a access denied, you have a windows COM-problem, if the 
virtual-device can´t be connected, use the hardware-manager to fix this, 
reinstall driver, windows etc ..
4. If you can see the driver in the hardware-manager, try to connect it 
with the windows.
5. If you have a connection you can use minicom on the image to test the 
connection, send a "v" to the reader.
6. Check if other software take the COM-port, like the ACG PCSC driver, 
this can block it.
7. Reuse the same USB / COM Port, windows likes to install new com-ports 
if you use different USB ports, the Hardware-Manager can fix this.
8. Keep in mind, this is a professional RFID Security, RFDUMP Mailing 
list, we will NOT FIX YOUR WINDOWS !

Any one like to write a FAQ out of this email ?

But if i start the live image, it comes the error: "reset resulted in nothing followed" by the Messagebox: "Could not reset the RFID reader". I can remember, when i started the system the first time - everything was ok and the program was working very well. But i havenŽt changed everything and now it isnŽt working.
