Since buying iPads, many PC users and users of USB hubs have found that the iPad doesn't charge at full speed when plugged in (and sometimes not at all). Thankfully, several popular motherboard manufacturers are remedying that problem with driver updates.

The iPad takes a bit more juice to charge than does the iPhone or iPod touch — and a lot of USB ports just weren't designed to output that much power. This meant a lot of users have had to plug their iPad into the wall rather than their computers in order to charge the device. And while the iPad has a pretty awesome battery life, this can be annoying when you do need a charge. Luckily motherboard manufacturers Gigabyte, ASUS, MSI and ASRock have each released a driver update (or separate utility) aiming to address these charging problems.
Of course, this only works if you actually have a motherboard by one of those manufacturers (which you probably do), but with all of them jumping on board, it's possible that other companies will follow suit. If you don't know your motherboard's manufacturer, you can use a tool like previously mentioned Speccy) to find out. Then hit the link for your respective motherboard to download the update, and let us know how it goes in the comments.
