This is the first time I have started a post in this community, so I want to say hi to everyone!
My real reason for posting, is to ask a question regarding the BlueSmirf. I just recently realized that USB only uses 4 wires to send signals. The BlueSmirf uses 4 wires to send signals. I have a robotics project that may be able to benefit from the ability to drop in a smirf instead of a USB cable. Can the smirf even handle this type of connection? Or is it only meant to handle serial cable replacement? Thanks in advance. Talk to you soon.

Well, no you can't. The two specification USB and RS232 are not compatible. You would need a RS232 to USB converter to do that.
A USB host controller would also work. I think you might be able to implement USB using a UART, although I really wouldn’t know. I have also found a TI TUSB3210 that implements the functionality of a USB host, allowing communications from embedded systems to USB. Unfortunately, it also needs a program, in 8051 code, but I think that there are several reference programs on the TI website.
