Splitter Cable for ADB(?)

[Zhinü]

I picked up a drawing tablet recently and noticed that my Quadra 950 only has one ADB port, instead of two. This leaves me with a bit of a situation, where I can either use my mouse and keyboard, or the drawing tablet and keyboard, because the drawing tablet doesn't have a passthrough.
Are there splitter cables for ADB? Or a passthrough dongle or whatever that'll allow me to hook up both the drawing tablet and the mouse?

An S-Video splitter cable would probably work, with the caveat that some cheap S-Video cables (and thus likely splitters, too) tie both the luma and chroma ground pins together. You have to make sure whatever you use doesn't, because for ADB that'd mean the power switch and ADB data lines get tied together.

I don't think it'd blow anything up, but it would probably also cause issues with either ADB data transfer, and/or the soft power switch behavior.
