The common faults when upload data with U disk controllers

The common faults when upload data with U disk controllers

1.  Insufficient power supply of controller, load too much, resulting in the battery low and the data uploading failed.
    Common faults: LED display screen with no response after the U disk inserting in(repower the display screen, it may work well);

2.  If the USB data extending line is too long, then the driving force of the USB port on controller is lacked, also may cause the uploading data failed;
     Common faults: LED display screen with no response after the U disk inserting in(repower the display screen, it may work well);

3.  The U disk format is correct, but no program data in U disk and reserving control card model incorrect, then the screen points out " no data ", after 2-3 seconds, it presents " remove disk ";

4.  When the U disk format is incorrect ( U disk format is NIFS but not FAT32), the screen points out " unknown disk ", after 2-3 seconds, it presents " remove disk ";

5.  There's also only a few U disk on the market cannot match with our BX controller, and caused the data uploading failed;Common faults:no response from LED display screen after the U disk inserting in.

Remarks:
1. The transmission distance of the U disk controller extending line is closed related with the main choice of the devices on controller、quality of the extending、line power supply and the kinds of  U disk which have different consumption;

2. BX 5th generation U disk controller gets prominent advancements on the U disk identification ability and the transmission distance of U disk extending line. For the identification ability of U disk, the firmware in 15th May,2012 could identify the most of the U disks.For the transmission distance of extending line, since 5th May,2012, our company offer the lines which with good efficience: BX-5UT/5U0/5U1/5U2 for 6 meters; BX-5U3/5U4 for 10 meters ( This is our testing standard );
