Nor when plugged into monitor. Will work fine if plugged into PCI card at rear of PC. Got Win XP Home with all updates. USB mouse and compact flash memory card reader works fine, tho, when plugged into keyboard USB. Is this a power issue? Be very grateful for advice.
checked it......yep. mouse is taking 100mA on one of the two keyboard USB ports on the MS internet k'board pro. How much does an Integral 256MB memory stick need? If I take out the mouse, using one port ( memory stick) I still don't get a recog for it. If I plug in the reader and the mouse ( 100mA each) no prob. Same with LCD panel.....two ports not in use..plug in same memory stick and nada. Does it require more than 200mA? At work I have a USB hub( two port) that is connected to the PCI USB card....the memory stick works fine with that( work is XP Pro). Thanks, G
Would be most grateful for explanation.Surely a memory stick plugged into one of the two available key board USB ports doesn't draw as much power as the two fuly functional devices currently plugged in( the memory card reader and the mouse)?
