FB3 not being recognized by my laptop

[andy_con]

my previous laptop was a Dell 1300 with XP, was a bit of an old and basic laptop so thought an upgrade would help.

now got an HP NC6400 with XP, better but the fb3 still dropped out ocne yesterday.

I run mine from my macbook pro, using Oracle Virtual Box (The Software formally known as sun virtual box) and I get it happening too.

Never in the middle of a show mind, or when it's really mattered.

I did find however that using the USB ports on the other side helped.. but thats not really applicable since I'm Mac'in it!

i have an original fb3 which is run on a seperate 5v input, but it kept dropping out really badly.

so i did the usb mod, although better its not perfect.

My problem is now solved.

In my case it turned out to be a fault with the USB daughter board with in my FB3.
So on Friday, with the help of Francesco and Rob, a replacement was sorted and I now have a working FB3 again.

A big thanks to them both and now I can concentrate on the up coming gig.

Glad you got it sorted.

I would also always try a new USB cable; might want to go all out and get the "gold plated diamondware" edition since you are running lasers off of it.

Did anyone ever experience a problem while the unit was running? I am curious to what the projector did.

Just a heads up that if the xD card in the FB3 isn't seated properly, it won't show up on USB either.

Frequently; usually there is a refractoryperiod in which the projector stops (no light, no galvo), but livepro is still under the impression all is well; then livepro suddenly gets very slow (1 fps, but still no actual output), and then it crashes (usually a lockup, sometimes a BSOD.)

Part of this is because the FB3 is a poor USB implementation and part of it is because Windows USB driver model is inherently flawed. Part of it, after all that, is because LivePro does not incorporate good thread safety and does not behave well when structures disappear from under it (like, for example, when memory associated with a USB endpoint is freed upon the endpoint disappearing; this was not possible in windows xp, but happens in vista and win7.)

They couldn't afford me.

I wasn't going to comment on dave's response... but this is almost word for word what I thought.
