Wrayth Posted April 20, 2005 Share Posted April 20, 2005 Okay,The first time you connect a USB device to a specific port, Windows treats it as new hardware and installs the driver for it. After that, it always "remembers" that device.Now if you plug that same device into a different USB port it treats it as a new device, but doesn't need to install the driver.So, the question is this... How do I clear that "history" or "memory" of connected devices?The issue I have is that with a blackberry device, after a time, it stops recongnizing the blackberry when I plug it in. So then I have to plug the cable into a different port to get it recognized. Since a machine only has so many ports, eventually I'm going to run out...If the device isn't connected, then it isn't listed in Device manager, so there's no way to "remove the hardware".Anyone have any ideas?Thanks Link to comment Share on other sites More sharing options...
Treeman Posted April 20, 2005 Share Posted April 20, 2005 You might run regedit and navigate here after detaching all thenon-functioning devices:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBIdentify which keys under this one correspond to the non-functioningdevices. Export a copy of them, then delete them. Then reattach one deviceat a time, loading the drivers per the manufacturer's instructions (someneed to be installed prior to attaching the device).I suggest that you export a copy as a safeguard, you can delete themafterwards. If removing a key causes problems (it shouldn't, but you neverknow), then you can double click the exported copy in order to put it back.Thread from Pcbanter.netTreeman Link to comment Share on other sites More sharing options...
