Wow, just tried my "Shareport" function for the first time since buying this product, Hardware Version: A4
Firmware Version 1.21, and didn't have any problems with it at all. I suppose I should "knock on wood" or something

.
My God, I'm soooo glad I heeded the warning in the beginning about not being able to flash back to previous version IF there was a problem AFTER flashing to the newer firmware version. I came so close to updating the firmware. I'm surprised you had trouble with 1.21. Glad you got it operating to your liking. There is nothing more frustrating than to purchase something only to spend hours and hours of troubleshooting time getting it to function properly.
The only thing I can suggest as to maybe improving this function is to make it so multiple systems can use it simultaneously. Surely that should be possible?

Well, one can only hope
