If it works, then a cheap USB to serial adapter should do it for you.

$139 - http://www.mikroe.com/en/tools/easypic6/
I've got the previous model $129, - main differences are SM components on the V6, COG display and keypad buttons, whereas V5 has 7-seg LED, and no dedicated key pad buttons, but has two AD pots the touch screen is extra as are the 2 x 16 LCD.... but they aren't that expensive There are also loads of plug on boards from $5 up so you can do basically anything you want... Mikro also do compilers and a free (up to 2K code size) BASIC, which is fairly easy to work with - worth spending some time browsing the site |

Way cool.
I think my bread board was $17 and the programmer was $10... have served me well for about 4 years, but that would be a treat. |

Hmmm... looks like the problem is more related to laptops USB ports. The interface doesn't get recognised on my Sony (Windows 7) or my friends Dell (XP).
Any more ideas from people regarding getting it running OK on laptops, or why it seems so finicky? Update: Well it seems to be related to whether you have programmed 4-axis or 8-axis joystick. Maybe it's the USB speed that's the problem? Anyway, having re-programmed as a 4-axis joystick Windows 7 now recognises the interface! . You are supposed to be able to calibrate USB Joysticks in Windows 7 - but I can't find an actual "Game Controller" tab in Device Manager (Windows 7 Home Premium). There is a HID-Game Controller one (now) - which doesn't allow any calibration, but it does still seem to work. Just got to see if it remains reliable! |

Norman, have you plugged it back in to your XP desktop machine to confirm that it's working OK. If so then I guess it's either down to windows power management software, or that on the two machines the current draw is taking the 5V supply down and the pic can't function.
Googled USB ports not functioning and came up with lots of hits: Most seem to be in relation to hub management under XP though http://support.microsoft.com/kb/817900 |

Yup - it had still been OK in XP - and I had also found the USB Power Management 'stuff' on the Net and tried that on the Lappy - but it made no difference. Many thanks for looking for me, though! Much appreciated! |

No worries,
The strange thing is I can't see that the interface would draw that much current that it causes the thing not to work. Do you have a meter so you can check the voltages that the PIC's receiving, on both the XP machine and your laptop. You might also want to check the current draw at the same time |

This has strictly got to be a Windows 7 thing, perhaps there is not a proper driver installed for Hi-Speed (USB 2.0) drivers. The main difference between the 4 axis and 8 axis version is that the 8 axis is only made for hi-speed USB.
Since you know the USB port itself is capable of doing hi speeds, it must be a driver issue within Windows. Did you try it on a Windows 7 desktop? |

BTW - it worked fine on my friends Compaq Laptop running Vista. More indication that it's software, I think. |

Awww... I read that wrong. I thought that you were saying that both you and your friend's laptop have Windows 7 and it wasn't working on them.
Did you use the PCB to build it, or did you direct solder your own connections? Perhaps there is a short somewhere? You were saying that it doesn't show up AT ALL in windows, or does it say "devise unrecognized"? |

Yeah - it didn't show up at ALL - never got as far as "device unrecognised". |
