Hello, I am using a Macbook pro with Mac OS X 10.6.6
I bought the Trendnet TU-S9 cable to connect it through the USB slot. I installed the drive from the Trendnet CD that they game me, but then I cannot find it when i run the pBasic program, I think that it is only looking for the serial drive and not USB drives, can anyone help me please and thank you

    You have to have a proper USB to RS232 serial adapter. In particular, the DTR (Data Terminal Ready) signal line has to be implemented as well as the transmit data (TX) and receive data (RX) lines. You have to install the proper USB driver for the adapter (from the adapter's manufacturer). Parallax sells an adapter using a chip from FTDI and FTDI (and others) sell their own version of the same. All work as far as I know. I have one from Parallax and one from FTDI and both work fine with Stamp boards and Propeller boards on my MacBook.

    You need to figure out what com port the mac has assigned the adapter. That will be the one you tell pbasic editor to use.

    I read the Serial Port tab in Preference and I think I found the problem. It said that I need the Keyspan USA28 and USA19. I think that i bought the wrong cable.

    Hello guys, I bought the RS-232 Cable with the USB cable. It tells me to go on the off site website to download the program for it, but I do not know which 1 I should get. there are VCP Drivers and D2XX driver. I have tried the VCP but the pBasic still cannot find my BS2. can anyone help me please and thank you

    If you have an FTDI (or Parallax) adapter, you want the Virtual Comm Port driver here. The Keyspan adapters also work and were what was available before Parallax began to use the FTDI chips.

    If PBasic can't find the BS2, make sure the BS2 has power and is connected properly. The Stamp Editor (and MacBS2) has to be able to "talk" to the BS2 in order to "find" it.
