After breakfast, with a few packets of glucose powder and milk powder in his pocket, Atletico Madrid left the school, what he wants most now is to complete the writing of the usB interface driver, and then he can download a large number of reference materials, and then he will naturally compete for the first place in the monthly exam, return to the fast class, kill the college entrance examination, be admitted to a prestigious school, harvest love, and embark on a new peak in life!

It's a little exciting to think about!

The Haiyan Internet café that I often go to is probably not able to go, and as soon as the boss saw Atletico Madrid yesterday, he immediately looked like he wanted to pick someone up. However, there are several Internet cafes in the county, so it would be nice to change one.

In this way, Atletico Madrid walked into the ******* Internet café.

This is a medium-sized Internet café, there is a special front desk cashier, she opened a temporary card of ten yuan, and took the Ic card Atletico and walked to the Internet café.

"A communicative device has been detected. The female voice of the electronic synthesis suddenly sounded in his ears, and Atletico paused and looked at the Ic card in his hand in a daze. It turned out that his finger happened to cover the metal contact area of the IC card.

e7u: "Encrypted message detected, trying to crack the ...... Cracking is complete. ”

“ID：1674，money：5。 0，ver：1。 13" appeared in front of Atletico's eyes, and he flipped over the Ic card, and the number 1674 was embossed in the lower left corner of the front.

"It turns out that the usB external interface module can not only read and write usB interfaces, but also other similar interfaces, especially this simple Ic card system!"

Although he found that he could modify the value of the money balance "by hand", Atletico still shook his head and gave up, even if it was modified here, the recharge data on the server side was not modified. Unless the Internet café billing system is the backward and completely local billing model, it can be changed casually, otherwise the billing server will find that the account amount is abnormal, and then it will be troublesome.

However, Atletico Madrid is still in a better mood because of this incident, and he may have thought too much about it before. You may not need to study the coding of the usB driver to write your own usB driver, the e7u will automatically try to complete the data communication with the usB interface of the computer.

However, the next situation was indeed different from Atletico's assumption, after the computer booted and inserted the card into the windows-xp's iconic blue sky, white clouds and green grass desktop, he put his right index finger on the usB port of the Internet café computer, and the bubble prompt of "new hardware discovered" did not immediately appear in the lower right corner of the computer screen.

After finding the reason, Atletico couldn't help but smile.

The IC card can be read directly through the skin, as its metal contact area is exposed, making it directly accessible to the skin of the finger. However, the four metal contacts of the usB interface are all inside the plug less than two millimeters thick, so fingers naturally cannot be inserted, and they cannot be connected if they cannot be contacted.

"I'm well prepared!" Atletico pulled out a miniusB cable from his pocket, which was the data cable of his mP3 player. Because he was worried about the failure of the "human USB flash drive", he specially brought the mP3 over as a backup mobile storage device.

Cut the miniusB cable from the middle with nail clippers, put the miniusB connector in your pocket, and tidy up the break of the other half of the cable. Let the red, black, blue, and green wires leak out a piece of metal wire, clamp it between the left fingers, and then grab the usB male plug with your right hand and plug it into the usB port of the Internet café computer.

"Discover new hardware. This is what the bubble prompt in the bottom right corner of Windows says.

"A communicative device has been detected. This is the text and voice prompt on the virtual panel of Atletico Madrid's "in front of your eyes".

After waiting for about five minutes, Atletico finally saw that the e7u prompted that "a communication connection has been established with a new device marked as a computer, with a maximum transfer rate of 480Mbps." ”

Atletico Madrid was overjoyed and hurriedly pasted some of the test files he had just found into the "Removable Disk (B:) (100gB of free space)".

Thanks to the reach of usB2. Efficient transmission at 0 standard limit speeds, the test files he prepared were quickly transferred, and Atletico Madrid looked at the results intently.

"System, where is the file you just entered?"

e7u: "New files added in the last 5 minutes: Glory days." mP3, old wolf, please eat chicken. WMA、I made money。 WAV and Northeast people are all living Lei Feng. SWF, sword like a dream. WMV, a bloody case caused by steamed buns. rm、mm1。 jpg、mm1。 BMP, Mars. GIF, create a new text file. txt, create a new Microsoft Word document. DOC, create a new Microsoft Excel worksheet. xls, create a new Microsoft PowerPoint presentation. ppt、setup。 exe、setup。 rar”

"Open the file!"

e7u: "Unknown file format, failed to open!" (15 lines of swipe)

e7u: "New file format discovered, parsing, please wait!" (15 lines of swiping)

e7u: "New file formats registered: TXT, WAV, BMP. ”

Atletico frowned, he pasted 15 files into the "human body USB flash drive" on his body, covering commonly used audio and video, pictures, documents, compressed package formats and executable programs, and the result was that only TXT, WAV, BMP three formats were parsed, and the content could be viewed in the mind, and the other 12 failed.

"Try to parse the glory days. mP3!" Atletico commanded again.

"e7u: Trying to parse the glory days. mP3, encrypted message detected, cracking attempt...... Predicted that it will take 31 hours and 34 minutes to crack, is it forced to crack?"

"No!"

Nodding slightly, Atletico understood what the problem was: the common denominator of the three file formats, TXT text files, WAV waveform files, and BMP bitmap files, was that the data was uncompressed. Other file formats are compressed by professional encoding tools to decontract the storage space, and it is very difficult to restore the information in them without the corresponding decoder software.

Fortunately, a lot of technical information in these encrypted compression formats can be found on the Internet, and many of them can even be downloaded to open source software code packages. The software source code is usually an uncompressed text file (a txt file with a modified suffix), which can be directly read by e7u to speed up the cracking process.

Therefore, Atletico Madrid will soon be able to directly view the content information of MP3, JPG, GIF, PNG, MPG, MP4, RTF, DOC, XLS, PPT, PDF, ZIP, 7Z and other format files in their own minds, but they cannot be opened directly for WMV, RM, RMVB, SWF, FLV, RAR formats, because there is no open-source decoder for these kinds of files on the Internet, and they can only be forced to crack. Atletico downloaded a collection of multimedia decoders and put them in the "B drive", hoping to slightly increase the speed of cracking.

After the file format problem was almost solved, Atletico began to fire on all cylinders, frantically downloading all kinds of materials that seemed useful.
