You should really try without the hub to see if it's the cause. nevermind the 15 minutes it'll break your local wireless network, if it works like a charm without the hub, then you're fixed.
Next move if the hub seem in cause, is to adjoin a power supply, ask around you, you don't know how much of these are lying around unused. check the proper polarities, same voltage, amps can be a little higher in case (if you find the right one exactly, don't look elsewhere). Try again the printer thru the powered hub and if it's working then you know. If not it's really either the hub itself or something fishy in the software.
Now, If trying without the hub doesn't change a thing, it's time for some maintenance on the G4:
- check with different USB cables first. Just in case, it sound always silly but…
- repair permissions (Apple disk utility)
- clear caches (use
OnyX)
-
Reset PRAM and NVRAM- Reset the motherboard (hence the USB ports) It's either
here (AGP/gigabyte ethernet) or
there (PCI graphics), depending of your G4. Note, press the button only ONCE, no more.
- If you have a voltmeter, check if the lithium battery is still within 0,2V of the mandatory 3,6V (mesure while the battery is in place not outside its place). If it's not, change it (electronics shop, radiospares, tandy and the like should have the thing, at a normal price)
