XPerf is a tool that allows you to take a detailed trace of various system activity like CPU, I/O and more…
Because of it's detail you can see stack trace counts, disk position offset graphs, driver calls and so on…
Is there a XPerf-a-like alternative for Linux and Mac OS X? What are the top-notch performance tools there?
If you are running Mac OS X 10.6, you can open up the Print & Fax pane in System Preferences. Once there, select the printer/scanner. On the right, there should be another menu. Hit Scan, then hit Open Scanner. Now you have full control of what to scan and the output format.
You need to update the driver. To update the driver you have two options:
Find a driver at the manufacturer's website.
Find the hardware ID and download from a driver repository site. In order to find the hardware ID do the following: Open Device Manager > Find the device your looking for in the list > Right-click the device > Click "Properties" > click the "Details" tab > In the Drop-down menu choose "Hardware Ids" and you will see a list of Hardware IDs. Copy one of the hardware ID's, then post into the search field at www.devid.info. There your likely to find the driver. Download the driver your looking for (preferably the one packaged by devID as they strip the drivers for unnecessary junk). Run the .exe and the driver will install itself. Make sure the device is connected when installing the driver.
