Deep VISA USB programming

[Zbigniew_StS]

Hello
Did anyone made any deep USB VIs for high speed communications?
I work with FTDI USB devices and need high speed (115200) communication for measurement radiomodem.
The FTDI has some examples (at FTDIchip examples) but it was made for ddl.
I'm looking any guidelines for VISA USB or any other strict LabVIEW solutions.

I've seen examples named USBRawBulkMain.vi but didn't found any manuals for that subject.
I work at win2000 and XP with LabVIEW7.1

best regards
Mikrobi

Have you read through the help that comes with NI-VISA about USB communication? If you haven't already, I recommend you check that out:

Start >> Programs >> National Instrumnents >> VISA >> NI-VISA Help >> Interface specific information >> USB

I guess my question is what exactly are you looking for? Are you looking for a manual or tutorial for USB communication in general? The following site has helped me out a bit in just learning some of the basics of USB communication:
