So on my iMac, I expanded my USB ports with a cheap (unpowered) USB3 hub. I've tried two different ones, in fact. I get strange performance with them. My disk backups are noticeably slower, and my mouse basically freezes about once or twice per day. The only way I can unfreeze it is by unplugging the hub and plugging it back in. Is this a well-understood situation? Am I better off with a powered hub? Are there worse and better unpowered hubs?
