The title is too long, but not the title of the party! But it can also be said to be heading the party, because the article said technical articles, technical articles but it is not, but I make a record. (The "yes", "not" can use this sentence, ha ha)

A few days ago my Samsung printer is not pink, and then change the HP M1005MFP printer. We can say that this type of printer is a "street car", and the highest price. Ado, connect the data cable, install the driver, everything is normal.

When printing the next day there was "a USB device to run with this computer is not connected properly, windows is not recognized" issue, in Device Manager in the "device descriptor request failed" error code 43. Then toss chant! The first is the driver uninstall and then re-download from the drive, the installation restart the computer, restart the printer, no; download the driver wizard to identify, results-driven wizard can not identify; then drive to install, restart from HP official download full-featured, the result was not . Tossing to and fro twenty-three hours! In fact, under the recall should toss this drive is futile, why say this because before the drive is installed, the print is normal. Now win more stable system, as in the case "drive out" before the emergence of many years is relatively rare.

Often frustrating computer great God who are saying "not on the soft to hard!" From then on top of the hardware it! This is not a repair computers have to use a process of elimination a test of memory, CPU, graphics card, this printer is simple, the only data that can move the line! In the absence of replacement of data lines, I changed a USB interface, how the results? problem solved!

Sometimes, when we toss things will brick dead end, ideas are often on the card will be a small problem. In fact, for this problem, when a drive reinstall does not work when you should consider going from the hardware side, rather than fiddle around and wasting time on the drive.

Or the phrase "not on the soft to hard!" Is not a technology technical articles, code words to record for future reference!
