I have problem with my USBwiz, I configured it in UART mode (with MODE 0 and 1 pins) and when I power it I obtain the banner, but when I introduce any command I have no response. The manual say that the USBwiz is coming without firmware and is necesary load it. The banner say exactly:
GHI Electronics
________________
Boot Loader 2.01
USBwiz (TM) 2.29
!00
When I configure the BOOT LOADER MODE, I just have "BL" as response. and no other response to anyone command. help me please, I need a clear guide How I could load the firmware and connect the USBwiz?

I have the CTS pin connected to GND.
Do you know if the MAX232 device is must be powered with 3.3 or 5.0 volts, I have it powered with 5.0 V. I think the problem is in the communications from the PC to the USBwiz, maybe the USBwiz is not receiving nothing.

The Revision number you see on manuals first page is related to the document. not to firmware number.
it is the same manual for the latest firmware 2.29
