I just purchased a 7-port "USB 2.0" hub with Power Adapter off eBay to replace a USB 2.0 hub that I lost the power adapter for. When I plug it in, Windows 7 claims to detect it as a "USB 2.0 hub" and auto-installs the drivers for it, but when I plugged my webcam into it, I got a message telling me it would "perform better if I plugged it into a USB 2.0 port." Suspicious, I tried a few file copy tests to a Flash drive and it took over 2 minutes to copy an 800M file to it (plugged directly into a USB 2.0 port, it took about 58 seconds.) I plugged the new hub into the exact same USB 2.0 port my old (unpowered) hub was plugged into (this is a new PC with USB 2.0/3.0 ports. No USB 1.1 ports.) Removing the new hub and plugging my old one back in, not only did file copy speed return to normal (58 seconds for an 800M file), but no "speed warning" when plugging my webcam into it. So my questions are: 1) Could a USB 1.1 hub incorrectly report it is a USB 2.0 hub? and 2) Could it truly be a USB 2.0 hub and it just installed the wrong drivers? (it's a generic hub and should use the same driver as the other.) PS: I plugged the new hub into a USB 3.0 port to see if it had any effect, and the same 800M file copy took over 10 minutes!
