You have to make an usb Host which is totaly impossible with 8051. I see two ways: 1. Use more suitable mcu, like ARM with usb Host 2. Use SD card and store data by using file system
Hi All, I am working on a usb host capable of 3.0 speed. When i connect a 3.0 pendrive, Linux in my board detects it as usb2.0 and not as usb3.0. Any pointers on what to check or how to debug? Thanks in Advance!
in our project, we are using 18f4620 controller.some information is saved in external eprom connected to this controller. i want to connect one pendrive (usb) to my board for collecting those data saved.

Hi to all i want to know how the set top box usb works and their circuits when we connect it pendrive. How it communicates with pendrive in detail. Any related information please give me thanks
usb spec requires devices to operate with Vbus of 4.4 V to 5.25 V. Beyond this range it's a matter of hope.
I am trying to design a usb pen drive(512 MB) equipped with Bluetooth/WiFi so that even when the pen drive is connected to a computer, we can remotely change the information contained in it. Any ideas? The structure I have thought of is like this. Computer----------(usb port)-----------------(Bluetooth)---------)))))))))[remot

It is an usbasp programmer closed in housing of old pendrive usb. Assumptions: buffered outputs going into state of high impedance after saving/reading is complete handling of input signal leve
Vinculum VNC1L with the VDFC frimware (like in the VF2F2 dev board) can handle to usb flash drives (not usb floppy or usb harddisk... only pendrives) with the VNC1L you will need an extra microcontroller (i.e. AVR) to manage the communication... or just use the VF2F2
have you tried with another usb pendrive?? how much current do you have at 5v for the vinculum??? i remember having this problem, but it was, or the pendrive doesn't have enought current so the 5V drops and it hangs, or the pendrive FAT is corrupted... maybe if you run a scandisk or checkdsk on the drive, or test (...)
unless you reprogram the pendrive firmware, which needs you to know which controller does it have, it's almost imposible... as it always will try to load as an usb mass storage device... (by the usb class and subclass) have you considered changing the format type (to something beside FAT or NTFS)? or have you considered some encryption (...)
