USB Infrared Toy / IRToyV2 fails to create a COM port
I have been using the IRT for a while.

I was sending some bytes with RealTerm. As usual, when no response came any more (e.g. Widget Mode) I disconnect the IRT from its USB connection and reconnect the IRT.

Although at reconnection the PC (WinXP) gave the  dong-ding reconnect sound, the COM port had disappeared. The Led of the IRT remains on. I did it several times with the same result.

I went to a previous XP restore-point, and my COM port of that time also didn't show up.
I went to the fw_update procedure. Jumpered PGC and PGD. Although not giving any COM port because it didn't exsit, the firmware was reloaded.

Stil the first deconnection(ding-dong)/reconnection(dong-ding) didn't made the COM port show up and the LED remains on.
The second deconnection/reconnection time I was too happy seeing again the missing COM port showing on my XP.

 Question:
What is the reason the IRT LED remains on, which was tha cause that the COM port never was created.
Was the fw-restore the only way to ged rid of that problem?
