Unfortunately, the USB Hub just quit working and after I replaced it, it's been working fine ever since.

You can but a new one here for $107:

Or here for $93:

Or, you can probably find a used one on eBay for less, if you want to go that route...

It's a pretty simple repair to do yourself.

Good luck,
John
