BS2 and USB

Hi All
has anybody out there interfaced a BS2 with the USB port on a MAC G4.
I need to send a "space bar" command to Adobe Premiere from a BS2.
On my old PowerMac I simply soldered in a plug to the spacebar switch
on the keyboard (old ADB style with pushbutton keys).
I don't have that luxury with the newer pressure contact USB
keyboards.
Any ideas no matter how obscure would be greatly appreciated.
cheers

How about keeping the old ADB style keyboard and connect it to your G4
via a USB to ADB converter.

that looks to your application as if the user had pressed the Space bar on
the keyboard? In other words, you want an electronically controlled Space bar?
To send a signal that the USB host (Mac, PC, etc.) will interpret as a
keypress, you need a USB controller chip programmed with code that makes
the chip look like a keyboard to the operating system. The chip has to send
the appropriate descriptors (data structures) to the host in response to
requests, and must transfer data in the expected format. This is possible
using just about any USB controller, but may be more trouble than you want
to take!
You can probably send data to the Mac using a USB-to-serial converter,
Serout, and an application you write to receive the data, but you then need
to figure out how to translate the Serout data into something that Premiere
sees as a keypress. I'm not a Mac programmer and don't know if this is
feasible.
