A reader sent an email and photos of his internal USB Hub mod for his B&W G3.

" Hey Mike,
Thought you might like to see this. I got tired of having to move my computer every time I had to plug in my digital camera or anything that needed a powered usb port. So I bought a pc internal 4 port usb hub and replaced my all but useless zip drive.
Best of all my zip bezel works great with no modification.

I assumed the USB cable was routed outside and plugged into one of the rear USB ports on the Mac. (He later sent a photo showing the cable rounted out a PCI slot to the external USB ports. I added the photo below)
