I just moved the LX710 keyboard to a different plug on the back panel, but it still shows up as one of the 4 devices on the slow bus. I'm assuming that a given hub cannot be accessed by both ehci and ohci drivers, which means I should put all the slow stuff on a separate hub, no? I may have another port powered slow hub but I'm assuming its too old to translate between full speed and 1.1 and I just tried it, its a usb1.1 device all the way. All of this leads to a pair of questions. 1, can a recently purchased accessory hub do speed translations? 2, would it do me any good to put the known slow stuff on such a hub so that all the motherboard ports (6) can then be claimed by ehci_hid? I know the wireless keyboard and mouse are low. And that scanner might be too, its quite long in the tooth. And that LX710 keyboard receiver when plugged into that old front panel breakout hub, it is not found early enough to control the bios. That could be a pita, forcing me to plug in a ps2 keyboard. They seem to be getting rare in these here parts. >From the lsusb -v, is that camera even able to do usb-2.0? If its a 1.1 only, then I may as well bin it and go look for a better one. Thanks Alan.
