Every time I plug in a usb device (windows) tells me it would work faster with usb 2.0. I have a cheapie white box, so I’m not surprised I have usb 1.1 inside. I saw a REAL cheapie pci card that would give me usb 2.0 and I ordered it. When I got it, the instructions said “No driver - plug n play.”
Then, in print so tiny I can barely read it with a magnifying glass, the instructions said something about the card not working if you have other usb things plugged in and it listed 3 connections? ports? something. Well, I plugged the card in and usb stopped working. So, I unplugged all devices and re-plugged only to the new card. One of my goals was to have unlimited usb ports. That ain’t happening. While I had the box open, I tried to see a way to disconnect the old ports on the back of the box but could see no way to do it. The connector is in some kind of little metal enclosure.
I do have 2 non-working usb ports on the front of the box. I figured I might as well pull their plug since they don’t work anyway and they might be causing a conflict. I looked at the wire to the front usb, turned my head, and pulled the wrong set of wires off. Now, my computer won’t start. In a panic, I tried to imagine how killing the usb would kill my pc. Then I noticed that I had pulled the connection to the front power switch and an led. I put them back together and still no power. Now in full panic mode, I discover one of the tiny wires is labeled reset, as is the tiny connector on the mobo. I pressed the reset button, instead of the power button, on the front of the case. That button had never worked before. Now that I am back in business, I figure, why leave well enough alone? 20 minutes later, I have my correct buttons back AND the front usb ports are working for the first time since I owned the box.
So, that is the first question: Why can’t I connect all these usb ports and why are the front and pci card ports now working.
Second question: lsusb shows the first two entries as 2.0 hubs. I now have 7 usb bus devices. No matter where I plug a device in, it is never associated with one of the 2.0 hubs but rather with one of the remaining 1.1 hubs. What’s going on?
Also, are the usb devices assigned on the fly? If I plug a device in, unplug it and replug it, where it connects seems random. Isn’t the physical port always the same address? Can these be fixed (permanent) if I want a usb backup hard drive or a webcam to always be on a 2.0 hub but not continuously plugged in?
