Hey Dan, how about developing a USB SX-Key backpack, either based off the USB2SER board, or a custom one? I do agree that using USB power provides an innovative workaround for programming sub 5V SX systems. I don't know if it can be done without modifications to the SX-Key though, perhaps a cleverly designed header that has a surface mount diode inserted into the socket for Vdd will work.

[/quote]I've thought about that. It could be done relativley easily. The problem is time. 
 

One could easily provide enough power to run the SX-Key from a USB port, the only issue

is making sure that your FTDI device notifies windows of the level of current that the device

draws (This is just an EEPROM value that needs to be programmed/changed). 

Again, just takes some time.

 

My vote is for a USB key. With the number of devices that I have which are serial, even the 

USB/Serial converter becomes a pain (Not all software packages will allow the use of 

Com5 or higher, which is a major factor for me wanting as many USB devices as I can get!)

 

USB is the way of the future! I'd gladly pay an extra $30 or $40 to have a USB key.
