I use 4 usb-to-serial adapters on my scope to connect all the various serial bits into a single 4-port usb hub and then a single usb cable back to the laptop. Works great but you have to use one of the "real" usb-to-serial adapters, ie one that passes through all the control signals correctly and not just the data.
I've tried "dolphin" brand (my favourite cause of the thin cables) from tandy, although they don't seem to stock them anymore... they work great.
Also the ATEN adapters work ok (in fact they have the same controller as the dolphin brand) but I don't like them as much cause the cables are heavier and shorter.
cheers, Bird
