where do i find on computer where alcor usb 2.0 card reader

they set iProduct to 'USB Hub 2.0', so Windows will show this. Furthermore, the manufacturer and product name are just strings, and I think Windows shows them when a device is plugged in. So, Windows and Linux will claim it's a USB 2 device because of the 'bcdUSB 2.00' line this should be bcdUSB 1.10 on a USB 1.1 device. So, this information is not truly detected, it's all burned into a small ROM on the USB device (hub in this case) and read out when the hub is plugged in (I assume at 1.5mbps USB 'low speed', since the computer won't know what speeds are supported yet.) IdProduct 0x0606 USB 2.0 Hub / D-Link DUB-H4 USB 2.0 Hub A few lines from lsusb, then explanation:īDeviceProtocol 0 Full speed (or root) hub Here's why Windows 'lies' (and Linux does too).

Unfortunately, (per Google), the true Genesys 05e3:0606 is a USB2 hub chip, but there are counterfeit 05e3:0606 that are not. I googled, and found that the hubmen will typically have 1 4-port USB hub chip 05e3:0606 and 7-port ones will have 2 of these chips. I just got one mail order (for some ridiculous price like $2.05) and it's USB 1.1 speed. In my case, I got a 4-port hubman a while ago in the store that was USB 2, but it wore out. 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! 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.) 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. 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. 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.) 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.' 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.
