USB device

Two questions.

What do you need to capture a signal from the USB 2.0 interface and have an SX28 recieve it?

How do you send data over the USB port from visual basic?

Thanks

They are not really USB2.0 devices, but are USB2.0 compatable. (You will find this the case
with many USB 2.0 devices) I use them to talk to VB on my PC, and transfer data between the SX and VB...

Hello,

·· You could greatly simplify things by using an FTDI chip (FT232R).· VB & the SX chip could then communicate serially over the USB connection.· Since there are plenty of examples of serial communication for both VB and the SX chips, this makes sense.· Also the driver is freely available.· I hope this helps.· Take care.
